Analysis for the application of solar assisted heat pump in Wuhan City, China
Wuhan City located in the central of China and its climate was hot summer and cold winter. Heat pump air-conditioners were main equipments for heating or cooling in Wuhan City. Solar assisted heat pump was an energy conservation technology. However, the development and application of solar assisted heat pump at residential buildings was limited by many factors, such as sunshine duration, system construction, running model and solar energy collector, etc. Therefore, a study of analysis for the application of solar assisted heat pump system was carried out to analysis its economical efficiency and applicability in Wuhan City. The general influencing factors on the running of solar assisted heat pump were discussed. The result showed that Solar assisted heat pump could reduce the limitation of solar energy heater and heat pump, especially in heating model in winter. Solar assisted heat pump could improve the performance of heat pump system and the utilization ratio of solar energy.
