A Study on Performance Factors of Seasonal Solar Energy Coupled Heat Pump System

In this paper, the physical model and the unsteady heat transfer mathematical model of the seasonal solar energy storage coupled heat pump system was developed. A set of system simulation program was produced based on Visual Basie software,which can simulate and analyze performance of the entire system. Key factors which have impact to system performance were calculated such as starting temperature of collector circulation pump,storage time,the volume of water tanks and collector area ratio(V/A)and starting temperature of ground heat exchanger circulating water pump.The results show that all these simulation results have a great significance on the research and design of the system. The results should be paid great attention in matching system design and researches on operation control strategy.
