Research on operating performance of CO2 ground source heat pump.

Author(s) : WANG J., SHEN J., LI F., et al.

Summary

According to the characteristics of the soil as heat source and sink, the operation rules are studied on the ground source heat pump with CO2 as a working fluid. The methods are brought forward and discussed to test the operating parameters and the control strategies of performance of the ground source heat pump. The analysis shows that the capacity and the pressure control based on the inlet water temperature of the gas cooler can be a better control strategy for CO2 ground source heat pump. And the pressure formula for operating control is also proposed. The main factors that affect the coefficient of the performance of the CO2 heat pump are analyzed.
