A solar assisted water source heat pump for Radiant Floor Heating (SWHP-RFH) experimental system with heat pipe vacuum tube solar collector as heating source and radiant floor as terminal device is proposed in the paper. The Mathematics Model of dynamic coefficient of performance (COP) for SWHP-RFH 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 heat pump on the thermal performance of SWHP-RFH is investigated. Based on the theoretical analysis, the mathematic model and design parametric of each component is established, the operation strategy and control scheme is proposed for a building in Beijing under different weather conditions. The research proposed a basis for the design and operation control of SWHP-RFH. The reported results conformed that the use of solar assisted water source heat pump radiant floor heating system in Beijing is acceptable.
