Japanese, In this paper, the authors introduce the calculation method for the heat extraction/injection coefficient of ground heat exchangers (GHEs) (heat extraction/injection rate per length and temperature difference) according to the operating conditions of ground source heat pump system. Then, the heat extraction/injection coefficients of GHEs with the different specifications and the different system operating conditions were calculated. The result indicated that the heat extraction/injection coefficient with the operating time of the GSHP system per day of 8 h was approx. 1.6 times compared to the coefficient with the operating time of the GSHP system per day of 24 h.

Evaluating Variability of Ground Thermal Conductivity within a Steep Site by History Matching Underground Distributed Temperatures from Thermal Response Tests
Yoshitaka Sakata; Takao Katsura; Ahmed A. Serageldin; Katsunori Nagano; Motoaki Ooe
Energies, 14, 7, 1872, 1872, MDPI AG, 28 Mar. 2021
Scientific journal, The variability of ground thermal conductivity, based on underground conditions, is often ignored during the design of ground-source heat pump systems. This study shows a field evidence of such site-scale variations through thermal response tests in eight borehole heat exchangers aligned at a site on a terrace along the foothills of mountains in northern Japan. Conventional analysis of the overall ground thermal conductivity along the total installation length finds that the value at one borehole heat exchanger is 2.5 times that at the other seven boreholes. History matching analysis of underground distributed temperature measurements generates vertical partial ground thermal conductivity data for four depth layers. Based on the moving line heat source theory, the partial values are generally within a narrow range expected for gravel deposits. Darcy velocities of groundwater are estimated to be 74–204 m/y at the borehole with high conductivity, increasing in the shallow layers above a depth of 41 m. In contrast, the velocities at the other seven boreholes are one-to-two orders of magnitude smaller with no trend. These high and low velocity values are considered for the topography and permeability. However, the relatively slow groundwater velocities might not apparently increase the partial conductivity.

The Effect of Groundwater Flow on the Thermal Performance of a Novel Borehole Heat Exchanger for Ground Source Heat Pump Systems: Small Scale Experiments and Numerical Simulation
Ahmed A. Serageldin; Ali Radwan; Yoshitaka Sakata; Takao Katsura; Katsunori Nagano
Energies, 13, 6, 1418, 1418, MDPI AG, 18 Mar. 2020, [Peer-reviewed]
Scientific journal, New small-scale experiments are carried out to study the effect of groundwater flow on the thermal performance of water ground heat exchangers for ground source heat pump systems. Four heat exchanger configurations are investigated; single U-tube with circular cross-section (SUC), single U-tube with an oval cross-section (SUO), single U-tube with circular cross-section and single spacer with circular cross-section (SUC + SSC) and single U-tube with an oval cross-section and single spacer with circular cross-section (SUO + SSC). The soil temperature distributions along the horizontal and vertical axis are measured and recorded simultaneously with measuring the electrical energy injected into the fluid, and the borehole wall temperature is measured as well; consequently, the borehole thermal resistance (Rb) is calculated. Moreover, two dimensional and steady-state CFD simulations are validated against the experimental measurements at the groundwater velocity of 1000 m/year with an average error of 3%. Under saturated conditions without groundwater flow effect; using a spacer with SUC decreases the Rb by 13% from 0.15 m·K/W to 0.13 m·K/W, also using a spacer with the SUO decreases the Rb by 9% from 0.11 m·K/W to 0.1 m·K/W. In addition, the oval cross-section with spacer SUO + SSC decreases the Rb by 33% compared with SUC. Under the effect of groundwater flow of 1000 m/year; Rb of the SUC, SUO, SUC + SSC and SUO + SSC cases decrease by 15.5%, 12.3%, 6.1% and 4%, respectively, compared with the saturated condition.

Japanese, Scientific journal, This study aims at developing the vacuum insulation panels (VIPs) with small thickness and light transmittance to contribute retrofitting insulation for existing buildings. The authors are focus on producing the slim and translucent VIPs with vacuum layer which hold by spacers. Firstly, the outlines of vacuum layer type VIPs were introduced. Next, the structural calculation was carried out as a mechanical analysis to determine the specific array of spacers to pillars supported type. Then, the heat transfer model applying the one-dimensional calculation was developed to predict the insulation performance of VIPs. After that, the authors conducted an experiment applying the guarded hot plate method in order to verify the apparent thermal conductivity of VIP according to the set pressure. The result showed that the apparent thermal conductivity was less than 0.1 W/(m<tt>･</tt>K) and was enough low. Finally, the VIPs with different core materials were trial produced and the apparent thermal conductivity were evaluated by the heat flux method.

A Study on Estimation of Ground Effective Thermal Conductivity as Probability-Weighted Average
SAKATA Yoshitaka; KATSURA Takao; NAGANO Katsunori
Journal of the Geothermal Research Society of Japan, 40, 1, 33, 44, 日本地熱学会, 2018
Japanese, This study proposes an indirect method to estimate the ground effective thermal conductivity in the formation of a depth over several tens to one hundred meters by averaging probability-weights of all soil/rock types. Thermal response test results are used as the in-situ measurements for determining a set of the individual effective thermal conductivities in the least square. The probability values of all soil/rock types are estimated at any location and depth through the indicator kriging interpolation with the adjacent water well data. In this study, 76 test data were used for analysis and the individual effective thermal conductivities of 8 soil/rock types, i.e., clay, sand, gravel, volcanic ash, Quaternary volcanic rock, Neogene fine rock, Neogene coarse rock, and bedrock were determined. For comparison, this study demonstrated a conventional method to estimate the ground effective thermal conductivity as a thickness-weighted average. The conventional method requires the direct geo-information such as geologic columns, which are not often obtained especially in the deep zones several meters deep. Also in this study, only 25 test data included the geologic columns. Thus, the conventional method resulted in the insufficient agreements of ground effective thermal conductivity between the estimates and the measurements. On the other hand, the analysis of the proposed method was performed in all 76 test data by using the probability estimates through the kriging system. As a result, all individual effective thermal conductivity values were reasonably obtained: the values of clay, sand and volcanic ash were almost equal to the reference values in texts. The value of gravel was relatively large probably because of the natural convection flows along the borehole during heating. The values of soft Neogene rocks were smaller than those of hard Quaternary volcanic rock and bedrock. The estimation errors of the ground effective thermal conductivity were close to the possible error by testing itself, except for the results over 3 W/(m･K). The K-fold cross validation (K= 10) also indicated the stability of the analysis results. This means the potential use of the method not only in the study area but also in other regions. This proposed method contributes to various heat transport problems in practice by providing the estimates of the ground effective thermal conductivity at any location. The method is also efficiently used to construct a database of the ground effective thermal conductivity, as shown in a case study of Sapporo City.

Japanese,  The purpose of this study is to evaluate an efficiency of ground source heat pump systems (GSHPs) in a standard residensial on a regional scale by the numerical simulation with the three-dimensional database of the effective thermal conductivity. The database was constructed through the indicator-kriging procedure based on the available borehole and water-well data to cover the depths beyond about 100 m for installation of borehole heat exchangers (BHEs). This study also proposed the methodology to determine required lengths of BHEs for a target value of seasonally averaged coefficients of performance (tCOP) in the GSHPs. The GSHPs simulation was demonstrated by using the Ground Club algorithm in a regular grid of 10 km over the northern area (the latitude > 36°) of Japan. First, this study showed that the COP values were calculated at about 4.0 in the Hokkaido area and about 4.4 in the Tohoku and northern Kanto areas when the BHE was assumed to be a standard length of 100 m. Next, the required median length of BHE for tCOP = 4.25 was estimated at about 80 m in the Tohoku and the northern Kanto areas. The smaller BHE length means that the intial costs for GSHPs could be efficiently reduced. On the other hand, the required median length was about 130 m in the Hokkaido area because the heating loads were relatively high in the cold region. The reduction ratio of CO2 emissions was estimated at about 45-60 % when the ground source heat pump systems were utilized over the area instead of the conventional electric, oil and gas boiler systems. The reduction ratio was relatively large in the Tohoku and northern Kanto areas, indicating the potential increase of GSHPs in the future.

Japanese, The purpose of this study is to develop a kriging interpolation method to estimate soil/rock types in the deep zones from the water well data for compensation of limited core-sampling data. The system provides the probability value of each soil/rock type by using the indicator kriging. The soil/rock types of the maximum probability are specified in a regular grid. The probabilistic-based system determines the data search radius and the anisotropic ratio of variogram range at each point according to the categories of topography, geology and data amounts with search radiuses. Re-estimation Score (ReS) in the leave-one-out cross validation is compared to determine the local parameter settings. A case study of the proposed method in the Toyohira River alluvial fan, Sapporo, Japan, shows that the kriging estimation covers almost the entire region. In addition, the averaged ReS is close to the highest value as the smallest search radius is applied.

Japanese, Scientific journal,
These studies aim at developing a performance prediction tool for a heat pump system taking the refrigeration cycle into consideration. This paper constitutes Part 1 in this series of studies. In this paper, it is indicated that the physics model of a heat pump system can be simplified on the basis of the calculation equation of the compressor. The authors simplified the physics model's calculation and developed an annual performance prediction tool for the heat pump system taking the refrigeration cycle into consideration. In this design tool, the calculated condition can be obtained by using the heat pump system's specification form and the annual performance can be calculated with high speed. In addition, it is possible to change a part of the equipment constituting the heat pump system such as the evaporator, condenser, and compressor. This tool can also perform calculation for the heat pump system with the control that the refrigerant's evaporating or condensing temperature is kept constant. The energy consumption of the water source variant refrigerant flow heat pump system installed in the office building was calculated by using the tool and compared to the measured consumption. The results showed that the relative errors between the calculated energy consumption and the measured consumption are 1.0% for the summer and 4.8% for the winter, respectively. Therefore, it is confirmed that the developed tool can predict the annual performance of the heat pump air conditioning system with acceptable precision.

Japanese, This study improves thermal response test (TRT) by using a set of fiber-optic distributed temperature sensors (DTSs) to estimate effective thermal conductivities in multi-layered formations. These sensors are installed into both inlet and outlet pipes (a U-tube) to obtain vertical profiles of heat transfer fluid temperature at TRT in more detail than those obtained by single DTS as in previous studies. When the borehole is constructed in a formation with several horizontally layers, this study analyzes the effective thermal conductivity in each layer under the assumption of line heat source. In the analysis, the slopes of fluid temperature on logarithmic elapse time are averaged within each layer, and heat exchange rate is calculated using a sum of linear slopes of temperature with depth in both inlet and outlet pipes. Offset and averaging span for DTS calibration are evaluated by laboratory sink tests at constant temperatures. Finally, an example of the proposed method at Asahikawa City, Hokkaido, Japan, is shown. In the example, the formation consists of three layers; unconsolidated gravel, clay, and pre-Quaternary shale. The solutions of the effective thermal conductivity in each layer are converged commonly when the thicknesses for analysis are larger than 20 meters. The conductivity in the upper-gravelly layer is about 1.5 times larger than those in the mid-clayey and lower-shale layers, probably due to groundwater flow advection. The thickness-weighted average of conductivities in the three layers is almost equal to the conductivity by conventional TRT with Pt100 sensors. The solutions are also valid in terms of total heat exchange rate. In addition, a series of effective thermal conductivities is invariable among the cases of DTS data: 1) calibrated in the heating period, 2) smoothed additionally by the FFT low-pass filter, 3) randomly sampled as the boot-strap method, and 4) calibrated in the recovery period.

Japanese, In order to investigate design and operating method of the hybrid ground source heat pump (HGSHP) system combined cooling tower, the authors developed a computer aided simulation tool for the system. Performance of the HGSHP system combined cooling tower, which has been installed in a new office building in Kitakyushu City, is predicted with the simulation tool. The result shows the HGSHP system can operate with high cooling seasonal performance factor (SPF) of 5.4. In addition, the authors investigated connection sequence and operation method of the HGSHP system. The result shows that the HGSHP system provides the highest cooling SPF when the cooling tower is connected in series with the ground heat exchangers (GHEXs) and the water as heat carrier fluid is circulated to the cooling tower ahead of the GHEXs. The system performance is additionally improved by using the simple cooling tower's activation control by the inlet temperature of heat pump unit.

Japanese, The subject of this study is to establish design and operation method of the ground source heat pump system affected by ground water flow. In order to investigate relation between the ground temperature response around ground heat exchanger (GHEX) and ground water velocity, multilayered ground simulation model is developed. It was shown that heat medium temperature is not kept in steady state in thermal response test when the groundwater flow in all geological layer is not generated. It is suggested that the thickness of geological layer with ground water flow and the ground water velocity can be estimated by analyzing the apparent effective thermal conductivity, which is obtained by the thermal resp_-1onse _-1test. Also, if the apparent effective thermal conductivity at elapsed time of 50 h is more than 4.5 W・m ・K ,the ratio of thickness of geological layer that have ground water flow with the velocity of 300 m・y^-1 is more than 25 % in all geological layer.

空気調和・衛生工学会論文集, 39, 207, 19, 27, The Society of Heating, Air-Conditioning & Sanitary Engineers of Japan, Jun. 2014, [Peer-reviewed]
Japanese, The authors demonstrate the feasibility of superposing the temperature variation caused by heat extraction or injection via ground heat exchangers (GHEXs) and the temperature variation influenced by the ground surface. A performance prediction tool for the ground source heat pump (GSHP) system that can consider the influence of the ground surface was developed. In order to validate the calculation precision of the tool, a thermal response test was carried out using a borehole GHEX with a length of 30 m and the outlet temperature of the GHEX calculated by the tool was compared to the measured one. The results showed a relative error of 4.3%, which confirmed that the tool can predict the temperature with acceptable precision. In addition, the authors predicted the performance of GSHP systems that contained different numbers of GHEXs with different lengths for the same total length in residential houses. The result showed that the heat exchange performance of 10 GHEXs with individual lengths of 10 m was reduced by 23% compared to that of a single GHEX with a length of 100 m.

Japanese, The authors established a technique for measuring heating or cooling output from a heat pump air conditioning system by applying the refrigerant enthalpy method. In this paper, advantages of the technique and estimation process of the heating or cooling output are introduced. In addition, field experiment with a water source heat pump unit was carried out to validate the established technique. In the experiment, the refrigerant saturation temperatures at inlet and outlet of compressor and compressor frequency, which are estimated in the technique, are firstly verified by comparing to measured values. As the result of experiments, it is confirmed that the established technique have possibility of omitting foundation of the pressure sensors and the measurement of compressors frequency in the technique. As the another results of experiments, the error of estimation values of heat quantity between the established technique and the conventional one is less than 5 % for cooling and 7 % for heating. Therefore, the technique for heat quantity measuring that the authors established has the potential to become the new measuring method for the heat pump air conditioning system.

Transactions of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan, 33, 134, 1, 10, 社団法人空気調和・衛生工学会, May 2008, [Peer-reviewed]
Japanese, This paper constitutes Part3 in the series of studies that aim at development of a design and performance prediction tool for the ground source heat pump (GSHP) system. The authors introduce calculation algorithm of the temperatures of the ground and heat carrier fluid in multiple ground heat exchangers for pipe arrangement of the GSHP system. Next, performance of GSHP systems with steel foundation piles is predicted with the design tool. In moderate climate region, since the GSHP systems using multiple ground heat exchangers with short length can operate with high efficiency as well as the GSHP system using a single ground heat exchanger with long length, the GSHP system with steel foundation piles has possibility to become popular. In addition, the authors investigated temperatures of the ground, thermal medium, and system performance according to the interval of the ground heat exchangers when annual heat extraction from the ground is equal to annual heat injection. The calculation results show that the applicable interval is 2m for the small-scale building. In a case where the large-scale building adopts the GSHP system with multiple ground heat exchangers, the adequate intervals for linear and lattice arrangement are 2m and 3m, respectively.

Japanese, A steel tank which is 2.0m by 4.5m by 3.0m is installed under the ground in order to investigate increase of heat extraction or heat injection by ground water flow in the ground thermal energy system (GTES). First, the authors define unit heat transfer rate, which can clarify relative merit of heat extraction or injection performance. Next, it was confirmed that the unit heat extraction rate increases according to the ground water velocity even in the case where the ground water velocity is relatively small (100〜350m/year). When the ground water velocity is 1400m/year, unit heat transfer rate with a double pipe ground heat exchanger is 16.12W/m/K and more than three times larger than the one with a single U-tube ground heat exchanger. The result shows that using a ground heat exchanger with small internal thermal resistance is effective to increase the heat extraction from the ground. In addition, from the result that the unit heat transfer rate of measuring was larger than the one calculated with considering only forced convection, it was indicated that the free convection is generated in the sand layer. Thus the authors investigated about the effect of the mixed convection.

Japanese, This paper shows method of calculation of the ground temperature with ground water flow and its application. First, method of calculation of the thermal response surrounding cylindrical heat source in the ground with ground water advection is shown based on comparing the thermal response for the cylindrical heat source with the one for line source. Next, the method's preciseness is verified by comparing thermal response calculated by this method and numerical calculation on condition that two ground heat exchangers are used. In addition, the impact that the ground water flow effects performance of the GSHP system and installation advantage is examined with the developed tool including this method. As the results of simulation of the GSHP system operation and cost analysis in case where the GSHP system with single ground heat exchanger is installed to a residential house in Sapporo, it is shown the ground heat exchanger of 45m is reduced for calculated condition that the ground water velocity in all ground layer is 100m/year. This result indicates that considering the ground water flow for the design of the GSHP system contributes to the reduction of the initial cost of the GSHP system.

Transactions of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan, 31, 112, 51, 59, 社団法人空気調和・衛生工学会, Jul. 2006, [Peer-reviewed]
Japanese, This paper demonstrates a laboratory experiments in order to investigate about thermal response for heat source (line or cylindrical) in the ground with ground water advection. The apparatus features to imitate ground water in a layer of sand filled into the apparatus. A prove buried in the sand layer can generate constant heat. Temperatures of the probe and each point in the sand layer were measured under a condition that the heat generation from the probe was constant. First, the experiments were carried out for several times by changing the ground water velocity. The time to achieve steady statement of the temperature change is shorter and the temperature is lower when the ground water flow is larger. Next, the each temperature variation calculated by the moving line source theory and numerical program applying finite difference method were validated by comparing with the measured one. The result showed that the calculated value reproduced the measured one. In addition, the authors proposed a method of estimation of the ground water velocity applying moving line source theory and estimated the velocity with experimental results as an example. As the result, it was confirmed that the errors between the velocities of the estimation with the method and the actual measurement are less than 100m/year or the relative errors are less than 20%.

Transactions of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan, 31, 111, 43, 51, 社団法人空気調和・衛生工学会, Jun. 2006, [Peer-reviewed]
Japanese, This paper constitutes Part 2 in the series of studies that aim at development of a design and performance prediction tool for the GSHP system. First, authors described the high-speed algorithm of calculation of the ground temperature response for heat extraction of the multiple ground heat exchangers. Next, a variation of ground temperature calculated by using this method was compared with the one calculated by using superposition of the theoretical equation. As the result, the method's preciseness was proved and the calculation time was about 1/135 compared to the method described this paper with theoretical solution. From these, it was shown that the method has performance required to use as a design tool. In final, if the ground heat exchangers often become short in such a case that foundation piles of the building are used as the ground heat exchangers, it is necessary to consider heat transfer from edge of the ground heat exchangers. Thus authors reviewed the modification coefficients in order to obtain average surface temperature of the ground heat exchangers influenced by the heat transfer. The temperature calculated with the modification coefficient was compared to one calculated without the modification coefficient.

Japanese, Heat exchange characteristics of steel foundation piles used as ground heat exchangers were evaluated by heat extraction tests and the calculation methods were indicated. First, heat extraction tests were carried out in such a way that the inlet fluid temperature kept constant. As a result of these tests, the use of a double U-tube indirect heat exchanger made possible to obtain an equivalent heat extraction to direct circulating heat exchanger in the condition using a steel pile with a large diameter of 400mm since ten days passed from the start of the test. Next, the effective heat conductivity of the surrounding soil was evaluated as 1.5W/m/K in comparison calculated temperature variations returned from the ground heat exchanger with a measured one. The last, thermal resistances of each type of the heat exchanger were calculated. In addition, a calculation method of the heat transfer in the indirect heat exchange type steel pile was shown. The values calculated with the method were compared to the actual measurements. As a result, it was demonstrated that calculated temperature variations returned from the ground heat exchanger reproduced those of measured in the case where steel piles with both diameter 400mm and 165mm were used.

A result of calculations shows that the GSHP system can reduce 56% of LCCO_2 compared to the oil boiler heating system.

Ground Source Heat Pump (GSHP) systems are gradually being introduced in Japan because they were defined as a renewable energy source in 2009 and have high potential for introduction as a renewable energy heat utilization technology. On the other hand, in order to accurately simulate GSHP systems, it is required to accurately simulate buildings and air-conditioning systems and to combine them as an ideal method. In order to combine the calculations of building thermal load and HVAC equipment with the GSHP system and other heat source equipment, a methodology using standard input/output was applied to link subprograms in different program languages. The building thermal load calculation was developed in C#, the HVAC calculation was developed in Python, and the GSHP system calculation was developed in Basic language. Furthermore, the authors developed a methodology to give input sheets of WEBPRO's standard input method as thermal load and air conditioning conditions, and a methodology to select the GSHP system according to the type of air conditioning. The main program and subprograms (heat source system (GSHP system) plug-in, air conditioning system plug-in, and heat load plug-in) that serve as the calculation engine of the integrated design tool were built on the cloud. Furthermore, a user interface for setting analysis conditions and a graphical display of the results are provided on the web so that users can freely set analysis conditions, perform analysis, and check the results., Japanese Branch of the International Building Performance Simulation Association, English

Estimation of Multi-Layered Soil Thermal Properties using Data Assimilation Method
Shoji Yutaka; Katsura Takao, Proceedings of the 5th Asia Conference of International Building Performance Simulation Association, 1028, 1035, 08 Dec. 2024
As global warming becomes a reality, the widespread adoption of shallow geothermal energy, known for its stability and ubiquity, is becoming increasingly important. The performance of shallow geothermal utilization depends heavily on soil thermal properties, such as the effective soil thermal conductivity and groundwater flow velocity. While methods for estimating effective soil thermal conductivity through thermal response tests are known, methods for estimating groundwater flow velocity have not been established. In this study, we propose a method to simultaneously estimate the vertical distribution of effective soil thermal conductivity, and the groundwater flow velocity by applying the Ensemble Kalman Filter (EnKF), a representative data assimilation method, to a ground heat exchanger model that considers multi-layered ground with groundwater flow. Numerical data assimilation experiment was performed on a quasi-3D borehole heat exchanger simulation with different soil effective thermal conductivities and groundwater flow velocities for each of three layers, using fluid temperature distributions in U-tubes as observed data. The results showed that the effective soil thermal conductivity and groundwater flow velocity can be estimated simultaneously by setting appropriate fluid heating conditions. This study proposed a method for estimating vertical thermophysical property distribution that takes into account the multi-layered nature of the ground. This method can be an important proposal to obtain more accurate simulation results for shallow geothermal applications in the presence of groundwater flow velocity., Japanese Branch of the International Building Performance Simulation Association, English

Improving the accuracy of deep learning models for solar irradiation prediction is crucial for the optimization of home energy management system (HEMS). This study proposes a new deep learning model to better perform open-loop prediction. The convolutional neural network (CNN) and long short-term memory (LSTM) models are introduced to enhance the accuracy of the model for different weather conditions and locations. The prediction results and performance of the model will be evaluated using solar irradiation data from regions such as Sapporo, Tokyo and Osaka in different weathers, and compared with LSTM based model and CNN model.

There is few research on the economics of smart houses involving storage batteries, and the optimal operation method of a battery introduced into an individual houses based on economical efficiency is not clear. Therefore, in this research, the authors try to optimize operation method of storage battery on an individual house of one day by bi-directional inverter for smart house system. In the proposed system, purchase from the commercial power system is minimized by optimal operation of the bi-directional inverter on the predicted data of the energy balance and solar radiation amount of the next day. In addition, surplus electric power obtained by solar power generation is sold to electric power company. The proposed system consists of solar cells, storage battery, bi-directional inverters and simulated load. A bi-directional inverter optimization algorithm is installed into the controller of the proposed system. The operation of the controller is optimized by the genetic algorithm (GA), and the objective function gives the minimization of the amount of purchase electric power per one day., The Japan Society of Mechanical Engineers, Japanese

The operation of the controller is optimized by the genetic algorithm (GA), and the objective function gives the minimization of the amount of purchase electric power per one day. As a result, compared to the conventional method (when the proposed system is not introduced), the purchase amount was reduced by 16.4%, 33.2%, and 13.7% in January, April and July. In addition, the electricity charges were reduced by 32.4%, 44.6%, and 56.1% in January, April and July., The Japan Society of Mechanical Engineers, Japanese

B-49 Development of a Low Flow Circulation Ground Source Heat Pump Multi-split System : Part-6 Development of a performance prediction tool for the GSHP system combined cooling tower
KATSURA Takao; NAKAMURA Yasushi; NAGANO Katsunori; OKAWADA Toru, 学術講演会論文集, 22, 3, 1875, 1878, 12 Aug. 2010
When the ground source heat pump (GSHP) system is installed to the commercial building in moderate climate region, ground temperature is raised by imbalance between cooling load and heating load. In this case, it is necessary to release the excess exhaust heat to the atmosphere with cooling tower. Therefore, the authors developed a performance prediction tool for the GSHP system combined cooling tower. In addition, performance of the GSHP system combined cooling tower, which will be installed in a new office building in Kitakyushu, is predicted with the tool. The result shows the GSHP system can operate with high efficiency long term although the cooling load is too much compared to the heating load., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

The authors investigate operating and design method of the ground source heat pump (GSHP) system combined cooling tower by using a computer aided simulation program. The GSHP system provides the highest performance when cooling tower is connected in series with ground heat exchangers (GHEXs) and the water as thermal medium is circulated to the cooling tower ahead of the GHEXs. Furthermore, the system performance is increased by set the water temperature in which the cooling tower is operated. Finally, we measure and evaluate the performance of a low flow circulation GSHP multi-split system combined cooling tower, which is installed an actual building., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

Two types of variable water flow control were installed to the low flow circulation ground source heat pump (LF-GSHP) multi-split system in the field experiment. It was demonstrated that one variable water flow control that keeps temperature difference between inlet and outlet of the heat pump unit has advantage from the viewpoint of follow capability of water flow control according to cooling output. The average SCOP during cooling season was 4.51 and the value achieved target SCOP of more than 4.5. Additionally, the LF-GSHP multi-split system combined variable water flow control could reduce approximately 80% of electric power consumption compared to the one with constant flow operation., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

Heating test of the low flow circulation ground source heat pump (LF-GSHP) multi-split system was carried out in the field and approximately 4.0 of SCOP were obtained on the some conditions. Also, antifreeze solution was applied as the thermal medium instead of water and heating and cooling test were conducted. The LF-GSHP multi-split system with antifreeze solution decreased only less than 15% of SCOP compared to the one with water in the both of heating and cooling experiment. In addition, daily average SCOP during heating operation was 3.33.5 even in the middle of winter season. These show that the LF-GSHP multi-split system has great possibility of adaptation also in the cold region., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

Field experiment with foundation piles as ground heat exchangers (GHEX) applying low flow circulation (LF) has been carried out since October 2006 in order to develop the LF-GHEX. The LF-GHEX can extract or inject nearly equal heat to the conventional GHEX even in a case where the low flow circulation system is adopted in the primary side. As the result, the authors confirmed that several GHEXs with flow rate of 8L/min extracted nearly equal heat to the conventional one with flow rate of 16L/min. In addition, the variation of temperature calculated by a simulation program for the GHEX could reproduce the measured one., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

A ground source heat pump (GSHP) system has been installed into a new building in the Soen campus of Sapporo City University. The ground thermal energy is extracted through the ground heat exchanger, steel foundation piles and boreholes and utilized in the ventilation system for heating and cooling of fresh air. The extracted heat is increased through the heat pump in the heating period. On the other hand, the cold energy from the ground is directly utilized for free cooling without the heat pump in the first year's operation in 2006. This paper describes the system flow and the result of the free cooling operation during summer. It is predicted that changes of operating conditions of the circulating pumps will lead to increase the system COP to around 3.0., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

A steel tank which is 2.0 m by 4.5 m by 3.0 m is installed under the ground in order to examine increase of heat extraction or heat injection by ground water flow in ground thermal energy systems. One experiment with a ground water velocity of 1350 m per year shows 1.5 times higher heat extraction compared to another one without ground water flow. The ground water flow doesn't show increase of temperature on the surface of the ground heat exchanger in spite of heat charge. Reduction of thermal resistance of the ground heat exchanger will lead to higher performance in such conditions., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

Field experiment on the thermal response test with ground water flow was conducted with a large-scale tank, which can imitate the ground water flow through the sand filled layer. The results demonstrated gradients of the ground temperature in the thermal response test with ground water flow are influenced by the range of the elapsed time. From the comparison between temperatures of measurement and calculations which apply the moving line source theory and the finite differential method respectively, it was indicated that the free convection is generated in the sand layer since the calculated temperature variations were larger than the measured ones. Thus the authors investigated the mixed convection., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese

We propose a "zero energy" ground snow melting tank using a steel pile. A theoretical analysis predicts that the use of a steel pile of 2000 mmφ would result in the snow melting of 174 m^3 during a winter season. Field experiments are conducted with two steel piles of different diameters, 600mmφ and 800mmφ. It spends 11 days and 18 days to melt the whole snow filled in the piles respectively. The measurements also indicate the average snow melting rate per the length of 23 W/m and 34 W/m for the steel piles of 600mmφ and 800mmφ., The Society of Heating, Air-Conditioning Sanitary Engineers of Japan, Japanese
