• An inverter-driven heat pump with a multi-tubular tube-in-tube heat exchanger for domestic hot water supply

  Journal of Building Engineering 54 104694 - 104694 2022/08 [Refereed]
   

  An inverter-driven heat pump prototype to supply domestic hot water (DHW) was built, within which a multi-tubular tube-in-tube counter-flow heat exchanger as condenser was installed including a desuperheater section and a condenser section. The heating coefficient of performance (COP) is reduced approximately 10% if the feed water temperature increases from 9 degrees C to 24 degrees C. When the inlet temperature of primary brine is 24 degrees C, the compressor frequency does not show any effect on the heating COP. While when the inlet temperatures of primary fluid are 5, 10, and 17 degrees C, the COP increases with the rise of the compressor frequency at first, but it stays almost constant when the compressor frequency is within 40-55 Hz. It is considered that the effects of opposite dependencies of heat transfer and the pressure drop in the condenser onto COP tend to cancel each other out to obtain a constant heating COP. When the produced hot water is 65 degrees C, the heating COP of our developed heat pump for DHW is the largest among those of other three different heat pumps.

  Abstract A building-integrated photovoltaic-thermal (BIPVT) system integrates building envelope and photovoltaic-thermal collectors to produce electricity and heat. In this paper, the electrical and thermal performance of roof-based BIPVT systems developed in the recent two decades and their effects on heating and cooling load of the building are reviewed. According to the use of thermal energy from the photovoltaic (PV) panels, the roof-based BIPVT are classified into three classes: cooling of PV, air heating, and water heating. Each class is further divided into several types according to the designs of the integrated PV roofs. Compared with BIPV systems, the total efficiency of most BIPVT systems is significantly improved. However, the decrease in electricity output and adverse impact on the indoor environment is also found for some designs of BIPVT systems in some climates. The advantages and disadvantages of various designs are discussed. Issues to be further studied in the future are also provided in this review.
