Background
According to different forms of the ground source heat energy exchange system, the ground source heat energy utilization is divided into a buried pipe type ground source heat energy system and a ground water ground source heat energy system. The buried pipe type ground source heat energy system has large occupied area, large construction amount and high cost. The underground water ground source heat energy system is affected by underground water quality, and the running time of the system is short.

The south area mainly supplies cold, and heat is transferred to the underground throughout the year; and in northern areas, the heating requirement in winter is high, and a large amount of heat is absorbed from the soil. After five to seven years of normal operation, the underground energy storage is colder or hotter due to unbalanced cold and hot use on the shallow surface of the facility. In areas with large annual refrigerating capacity, the underground energy storage temperature is higher; in the area with high heating utilization rate, the energy storage temperature is lower, so that the temperature difference of the system is small, the heat exchange efficiency is reduced, the equipment efficiency is reduced, and the surrounding ecological structure is influenced.
Thus, ground source heat pump applications are affected by different regions, different users, fuel prices; the disposable investment and the operation cost can be different according to different users; the utilization mode of the underground water is limited by local underground water resources; the well drilling and pipe burying are limited by the field greatly, and enough area is needed for well drilling and pipe burying; the design and the operation have larger requirements on annual cold and heat balance, and the heat discharged downwards in summer and the heat taken from the ground in winter are approximately balanced.
