摘　　要：地源热泵系统既能供热,又能制冷。地源热泵系统通过其中的水源热泵机组从岩土体提取热量,实现向建筑物供热。传统上一定规模的地源热泵系统通过水系统八个阀门切换,实现冬夏季节供热、制冷的转换。随着技术的进步,内切换水源热泵机组开始工程应用。本文分析地源热泵系统制冷制热工况两种转换方法,比较其特点,通过实际工程介绍其应用。Ground source heat pump system can provide both heating and cooling, which uses the water source heat pump unit to extract heat from ground to supply heating to buildings. Traditionally, the ground source heat pump system switches the conditions of heating in winter and cooling in summer by switching eight valves of the water system. With the progress of technology, the internal switching of water source heat pump unit began to be applied in engineering. This paper analyzes two conversion methods of ground source heat pump system cooling and heating conditions,compares their characteristics, and introduces their applications through practical projects.
