“…Similarly, the performance of a heat pump system using circular and triangular tube configuration was investigated by Mohanraj et al 17 It was reported that, the triangular tube PV-T collector evaporator collector has improved the COP, condenser heating capacity and panel efficiency by about 3-5%, 3-7% and 4-13%, respectively. Manzolini et al 18 studied the performance of a heat pump using photovoltaic assisted roof tile solar air heater and reported with 5% energy savings. Zhou et al 19 investigated the performance of heat pump system using a micro-channel PV-T collector evaporator and reported with an average electrical and thermal efficiency of 15.4%, 56.6%, respectively.…”

In this research, a photovoltaic-thermal collector assisted heat pump has been developed and tested its performance under the tropical climatic conditions of Malaysia. The refrigerants such as, R134a and R1234yf were selected based on its thermodynamic and thermo-physical properties. The temperature of the photovoltaic module was theoretically predicted under the influence of tube diameter, tube spacing and refrigerant mass flow rate. Further, the energy performance of the photovoltaic-thermal evaporator and the heat pump system are investigated experimentally. Finally, the economical feasibility of the photovoltaic-thermal collector evaporator was assessed for the period of 20 years. The results showed that, the tube spacing and diameter of the copper tubes used in the photovoltaic-thermal evaporator/collector using R134a and R1234yf were optimized to 80 mm and 12.7 mm, respectively. It was observed that, during the clear sunny day, the average photovoltaic module temperature was reduced to 30.9 °C under the influence of panel cooling using refrigerant. The output of the panel was enhanced by 21%–44% with increase in solar radiation from 400 W/m2 to 1000 W/m2. The coefficient of performance of the heat pump was varied from 4.8 to 6.84 with an average coefficient of performance of 5.8 during clear sunny days. The life cycle economic analysis indicated that, the photovoltaic-thermal collector evaporator assisted heat pump has a payback period of 3 years, whereas the reference photovoltaic system has a payback period of 8 years.

Heat pumps (HP) can be used for a variety of residential, commercial, and industrial applications and offer a cost-effective replacement for conventional heat recovery systems. Hybrid systems that can be utilized for drying, heat storage, and water heating include solar-assisted heat pumps. Solar energy as a heat source for heat pump dryers improves performance and energy efficiency. This review aims to examine the concept of a solar collector, PV, and PVT technologies-assisted heat pump. The use of solar collectors to assist heat pump technology is a longstanding practice that remains in use today. Solar collectors that utilize direct solar heat sources and convert them into warm water or space heating are highly efficient. The concept of a PV and PVT-assisted heat pump is gaining popularity. The heat source utilized can be either single or multiple. Integrating a heat pump with a PVT as an evaporator result in higher heat performance. Using multiple heat sources is a more effective way to meet the cooling or heating requirements than relying on a single heat source. This review focuses on the mathematical modeling of a heat pump system integrated with PVT. Aspects of the mathematical model are critical for estimating the performance of heat pump systems in conjunction with solar collectors, PV, and PVT technologies. Readers who design and use heat pump technology must comprehend efficiency, COP, and configuration models.
