摘　　要：提出一个以土壤作为冷源直接供冷空调的新构想,并在哈尔滨地区建立了相应的实验系统。根据该系统运行一个空调季所得实验数据,除获得一些重要参数(如季节供冷系数、平均供冷率)外,着重对它在运行期间的供冷特性进行了研究,得到一些重要分析结论。实验结果还表明,所提出的土壤直接供冷系统在一定地域范围内具有巨大节能潜力。A novel conception, e.g. the ground is used as heat sink directly for air conditioning, was presented, and a corresponding experimental system was set up in Harbin area. According to the experimental data obtained after the sys- tem operated over an air-conditioning season, its cooling characteristics during the operation were laid stress on study and some important analytical conclusions were found, besides some important parameters, such as the cooling seasonal per- formance factor and the average cooling rate, were obtained. The experimental results also show that the presented ground sink direct cooling system has great energy saving potentiality in a definite region.
