Energy analysis of cool storage and discharging processes in soil

Based on the analysis of the cool loss process of cool storage system in the soil, the concepts of underlayment cool loss and heat transferred cool loss were presented, and the calculated models of underlayment and heat transferred cool loss of underground heat exchangers were established. Moreover, in order to evaluate the operation efficiency of the buried pipe bundles, the average cool discharging factor model of the underground heat exchangers system was set up. Through the theoretical analysis and simulation, the influences of the initial soil temperature, pipe distance and pipe bundle structure on cool loss of the soil cool storage system were analyzed and the cool loss change rules with soil initial temperature and pipe distance were put forward, and these will provide theory proofs for the optimal design of underground heat exchangers of the soil cool storage system.
