Abstract: System which is based on TRNSYS software, set up two ground ｓｏｕｒｃｅ heat pump low temperature radiant floor heating system, the traditional ground ｓｏｕｒｃｅ heat pump low temperature radiant floor heating system and join the buffer tank of ground ｓｏｕｒｃｅ heat pump low temperature radiant floor heating system, assess the performance of the two systems and the energy-saving efficiency of the research results show that adding water tank system heating ｌｏａｄ is 1.41 times that of the traditional heating system, the system total energy consumption and water pump energy consumption was reduced by 27.2% and 91%, respectively, is mainly due to the buffer tank running change the operation mode and control strategy of heat pump.
