Hourly Simulation Study of Intermittent Operating Conditions for Ground Heat Exchanger in the Hot Summer and Warm Winter Areas

Abstract

This paper dynamically simulates the soil source heat pump air conditioning system of a library in Nanning with the eQUEST software combined with the geology and climate characteristics, unit parameters. Comparing the simulated values with the measured values to verify the correctness of the model. Then simulate and analyze the variation of ground temperature rise at well bore with long-term intermittent operation for the system and the influence of different well spacingground and backfill materials thermal conductivitywell depth on the outlet temperature and the ground temperature rise at well bore. The simulation results show that the reasonable selection of relevant parameters has important significance to improve the operating performance and economy of the system.
