Photovoltaic-Thermal(PVT)-Heat Pump Hybrid Hot Water System:Design and Operational Performance
摘要
Abstract
A photovoltaic-thermal(PVT)-heat pump hybrid hot water system was designed,and its annual op-erational performance in Jiaxing was simulated using POLYSUN.The results indicate that the system per-formance varies significantly with the seasons.During summer,when solar radiation is abundant,the system a-chieves higher heating capacity,power generation,and solar fraction.In winter,however,due to reduced solar radiation and lower ambient temperatures,the performance of the system shows a slight decrease.The solar fraction of the system is approximately 66％in summer and 59％in winter,with an annual CO2 emission re-duction of about 26 110 kg.关键词
