Design and test of the ground heat exchanger ground-source heat pump system for a villa

Presents the calculating method of ground heat exchanger in the ground-source heat pump system. Represents the operating data in summer and winter of a year. As a result, the heating capacity, cooling capacity and COP of the system can meet the design conditions, and the heat charge capacity of the heat exchanger is slightly smaller than the design condition, and an appropriate allowance should be considered.
