土壤热源与热泵联接运行冬季工况的试验研究

研究利用土壤热源的一种新方法，即利用我国长江流域丰富的地表水作为蓄能和传热介质，以井作为竖直埋管形式．提取土壤热量来作为热泵系统冬季供暖热源．测试结果包括不同埋管尺寸、不同水循环方式以及各种工况下运行参数对热泵性能和取热量的影响．

An Experimental Study on a Heat Pump Using Soil Heat Source in Winter

The heat source is of great importance to the operating characteristies of a heat pump,the economy and the selection of the type of a system.A new method for making full use of the soil heat source is investigated. In the experimental setup, water on the ground surface of the Yangtze Valley is used as a medium for energy storing and mass transfer.The well,while extracting heat energy from inside the soil,acts as a vertically buried pipe.The results of the experiment including the influences of different sizes of the pipe,different modes of water circulation and different operating parameters on the performance of the heat pump and the amount of heat extracted are given.
