Experimental study of performance of solar-ground source heat pump floor panel heating in severe cold area

Presents a demonstration project of solar-ground source heat pump heating and cooling in severe cold area. According to the characteristics of the combination system of solar-ground source heat pump and floor panel heating in the project, puts forward a new operation mode and executes preliminary heating experiment. The results indicate that this operation mode has a prominent energy saving effect, the average COP of the heat pump is 4.3 and the mean heating coefficient of performance of the system can reach more than 8.
