摘　　要：地下水源热泵是解决空调高能耗的有效方法之一,但有些地下水源热泵工程并不像预期的节能,所以一套地下水源热泵能耗模拟的方法对于地下水源热泵的发展来说是至关重要的。本文以石河子市一地下水源热泵系统工程为例,用DEST-c软件模拟得到该建筑物的全年逐时冷热负荷;同时以压缩机部分的性能系数随部分负荷率变化曲线为依据,用Visual Basic编制出了地下水源热泵系统的能耗计算程序;结合模拟得到的逐时冷热负荷,用程序计算出最终的制热、制冷能耗;最后将计算结果和系统实际能耗比较,偏差在2%以内,从而证实该能耗模拟方法的可行性。Ground-water heat pump is one of the effective methods to deal with the problem of high energy consumption of air conditioning.But some ground-water heat pump projects cannot save energy as expected,so a set of consumption simulation methods is essential for the development of the pump.This paper took a ground-water heat pump project on Shihezi as a research subject,and got the building＇s hourly cooling load by using the simulation software DEST-c;based on the compressor section coefficient of performance with part load rate curve,we composed the energy consumption program by using Visual Basic;combined with the simulated hourly cooling and heating load,we calculated the final heating and cooling energy consumption with the program.The calculation results and actual energy consumption,deviation between the calculated and real consumption was within 2%,confirming the feasibility of the energy consumption simulation method.
