武汉地区常规地源热泵与冷却塔复合地源热泵的运行比较

The Results Comparison of A Ground Source Heat Pump and Aground Source Heat Pump Systemaided by Cooling to Werin Wuhan

针对武汉地区某办公建筑,利用DeST软件计算其全年逐时负荷。利用TRNSYS软件对该建筑分别建立常规地源热泵系统(GSHP)模型与冷却塔复合地源热泵系统(HGSHP)模型,通过模拟发现冷却塔复合地源热泵系统更利于土壤的热平衡,且机组和系统全年的COP也较高。

The building load of a certain office building was calculated by DeST. A ground source heat pump model（GSHP）and a ground source heat pump system aided by cooling tower model（HGSHP） were established by TRNSYS. Comparison of the simulation results using TRNSYS indicatedthat the ground source heat pump system aided by cooling tower model was better at the heat balance of the soil and could provide high COP of heat pump unit and the system.
