摘　　要：针对传统地下水源热泵空调(conventional ground water heat pump air-conditioning,CGWHP)系统对地下水储热利用有限的缺陷,提出一种地下水预热新风一体化热泵空调(integrated ground water heat pump air-conditioning,IGWHP)系统。基于分布参数法和集总参数法,建立了IGWHP系统稳态仿真模型,对组成系统部件和整个系统的制热性能进行仿真计算,分析空调热水对IGWHP系统性能影响,同时比较分析IGWHP系统和CGWHP系统的制热性能,并进行了实验验证。研究结果表明:IGWHP系统较CGWHP系统有显著节能优势。当热水供热温度从40℃升高到55℃,IGWHP系统的能耗比CGWHP系统平均下降36.12%。仿真结果与实验结果吻合较好,仿真值与实验值的误差在±10%以内。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%.
