According to the characteristics of the soil as the heat source and sink, the operation rules are studied on the ground source heat pump using CO2 as a refrigerant. The methods are brought forward and discussed to make certain the operation parameters and the control strategies of the ground source heat pump. The analysis shows that the capacity regulation 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 operation control is also proposed. The main factors that affect the coefficient of the performance of the CO2 heat pump are analyzed.
Keywords. CO2 ground source heat pump; cycle performance; operating control
