N2 - Ground coupled heat pump (GCHP) is an efficient air-conditioning technology, which is good to sustainable development of energy use. In order to make GCHP system operate efficiently in long term, soil needs to be maintained heat balance in an annual cycle. If necessary, auxiliary heat or cold source is also needed. A soil heat balance theory was proposed, and it contained heat balance equation and annual heat balance rate of soil. Soil heat balance point and floating range were derived, and the upper and lower limit of the range correspond to cold and hot critical region, respectively. And heat balance point 80% and floating range 65%~95% were obtained according to experimental data, which can be used as indicators to measure soil heat balance. The soil heat balance theory can be used to investigate the regional applicability of a GCHP system with auxiliary heat or cold source, and design an efficient system which can maintain soil heat balance.
