• Ground Source Heat Pump (GSHP)
• Ground Heat Exchanger (GHE)
• Intermittent Operation
• Adjustment Ability

Analyzes the ground adjustment ability in thermal equilibrium of the GSHP system during intermittent operation of 1:1 and 1:2 in summer through experiments. The result shows that the intermittent operation of 1:2 can maintain good heat transfer efficiency and better achieve restoration of the soil temperature field. For the intermittent operation of 1:1, however, the result of heat transfer of the GHE will become worse. It can be also concluded that through reasonable manual control in intermittent operation, strengthened heat transfer can help maintain the efficiency of heat pump units and better solve the problem of the soil thermal equilibrium. The conclusion can provide a good reference for running GSHP systems.
