Abstract
Combined the advantages of the ground-coupled heat pump and frozen soil thermal storage technology, a heat pump air conditioning system, integrated soil thermal storage and ground-coupled heat pump (GCHP) system, was presented. The geothermal heat exchangers of the GCHP system and the thermal storage devices are united in the system. During the off-peak period, the cooling load is stored on the underground soil partially or fully to satisfy the air conditioning load requirement during the on-peak period. Based on the energy balance, the mathematical model of soil thermal storage and release processes was established. The simulative calculation was worked out using the model of solid phase increasing method. The technical feasibility of the application was analyzed and theoretical support was supplied for the application of the integrated soil thermal storage and GCHP system.
