| Solar heat pump has a combination of heat pump technology and solar thermal technology. Solar heat pump can achieve the purpose of heating with high efficient. Air source heat pump using air as heat source which is environmentally friendly, non-polluting.A computer simulation program was coded with C# language. The thermodynamic properties of refrigerants and air properties, the models including the compressor model, air-cooled evaporator model, water-cooled evaporator model, water-cooled condenser model, the capillary model are established, and principle of simulation methods of the various components are described. Basing on the components simulation model, the solar energy heat pump, air source heat pump simulation system was established. The references are provided for experiment by the simulation results.The test bench and measuring system of the solar energy heat pump system, air source heat pump system are established, and the principle of system is introduced. Experimental study is conducted in different operating conditions, and experimental data are analyzed by software. It is analyzed the influence of solar radiation, evaporation temperature and condensation temperature of solar heat pump, air source heat pump system on heat absorption, heat capacity, compressor status, COP of the system.The bases for design and operation of solar heat pump system, air source heat pump system are provided according to the analysis. Through comparison of experimental data and simulation data, the practicality of the simulation program is to be confirmed. |
