Özet
One method to reduce energy consumption in buildings is using solar assisted heat pumps, in which the combination of heat pump and solar collector is used to improve the thermal performance. In this paper, TRNSYS and EES software are used to simulate the performance of an indirect expansion solar assisted heat pump. Dynamic simulation of the system is performed by changing parameters such as mass flow rate of collector working fluid and the collector area in five climates including Hot/Dry, Cold/Dry, Moderate/Humid, Hot/semi-Humid, and Hot/Humid. The results show that, in January, the Cold/Dry climate had the lowest free energy ratio (FER) because of high space heating load. In this month, Hot/semi-Humid climate has the highest FER, because of the higher solar radiation and no need to space heating. The annual FER in Hot/Dry zone is 71% which is higher than that other zones. The lowest FER related to Moderate/Humid climate due to high humidity and cloudiness.
