description This paper studies the efficiency of ground source heat pump(GSHP) used in refrigeration and heating, comparing it with air source heat pump (ASHP) by means of theoretical analysis and experiment. The results were as follows, the cooling efficiency of GSHP in summer is higher than that of heating in winter because of the heat is transferred from high temperature to low temperature during cooling in summer, which can be compared to heat pipe; By calculating the power consumption of pump and fan, it is found that theoretically GSHP unit and system have higher heating efficiency than ASHP; The experiment shows that the daily average COP of the unit and the system is 4.22-4.62 and 3.26-3.55, respectively, both the unit COP and system COP of GSHP is higher than that of ASHP, which is consistent with the theoretical analysis.
