IIR documentSummary
The advantages of a combined ground-coupled heat pump and ice storage technology, a new integrated system with cooling storage in soil and ground-coupled heat pump, are presented. Based on the theory of heat transfer coupled with phase change, a mathematical model of soil cooling energy charging and discharging process of inner and outer pipe in buried pipe bundles is established. The charging and discharging operation performance of single inner and outer pipe under simulative condition is analyzed and compared through the simulation. Moreover, the heat transferred and underlayment cooling loss of single buried heat exchanger in charging and discharging process are analyzed primarily.
