In order to solve the instability and intermittence of solar heating system, a experiment system of indirect expansion solar assisted water source heat pump radiant floor heating is proposed in the paper. The mathematics model of coefficient of performance for the system is presented after analyzing the operation principle in different conditions. The influence of the inlet and outlet temperatures of collector and floor coil, the mean temperature of storage tank, evaporation temperature of heat pump on the thermal performance of SWHP-RFH is investigated. Based on the theoretical analysis, the operation strategy and control scheme are also proposed, which provide theoretical bases for the design and operation control of the system.
