摘要：

An integrated ground water heat pump air-conditioning (IGWHP) system is proposed to solve the problem of limited utilization of ground water thermal storage in conventional ground water source heat pump air-conditioning (CGWHP) system. Based on distributed parameter method and lumped parameter method, a steady-state simulation model of IGWHP system is developed, and the heating performance of the proposed system is simulated. The influence of hot water on the performance of IGWHP system is analyzed, and the heating performance of IGWHP system is compared with CGWHP system. The results show that IGWHP system has good energy saving advantages over CGWHP system. As heating temperature of the hot water increases from 40℃ to 55℃, the energy consumption of IGWHP system decreases by 36.12% on average compared with CGWHP system. Moreover, the simulation results are in good agreement with the experimental results, and the error is with in ±10%. © 2023 Chemical Industry Press. All rights reserved.
