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.

在这项研究中，开发了光伏热收集器辅助的热泵，并测试了其在马来西亚热带气候条件下的性能。根据制冷剂的热力学和热物理性质选择了制冷剂，例如R134a和R1234yf。理论上在管直径，管间距和制冷剂质量流率的影响下预测光伏组件的温度。此外，还对光伏热蒸发器和热泵系统的能量性能进行了实验研究。最后，对光伏集热器蒸发器的经济可行性进行了为期20年的评估。结果表明，使用R134a和R1234yf的光热蒸发器/收集器中使用的铜管的管间距和直径分别优化为80 mm和12.7 mm。观察到，在晴朗的晴天，在使用制冷剂的面板冷却的影响下，光伏组件的平均温度降低至30.9°C。随着太阳辐射从400 W / m增加，面板的输出提高了21％–44％²至1000 W / m ²。在晴朗的晴天，热泵的性能系数在4.8到6.84之间变化，平均性能系数为5.8。生命周期经济分析表明，光伏集热蒸发器辅助热泵的投资回收期为3年，而参考光伏系统的投资回收期为8年。
