Testing of ground water source heat pump systems in summer

Tests and analyses the operating condition of a ground water source heat pump system in summer. The results indicate that the temperature of the room is about 255 ℃. If the production well is close to the injection well, the temperature of the production well rises with the cooling time, so the distance of the two wells should be increased. Economic analysis results show that the operating cost of the heat pump system is cheap, but the initial investment is high.
