基于冷却塔逆用的缓解土壤冷堆积研究

Mitigation of soil cold accumulation based on inverse cooling tower

土壤源热泵系统单独长期运行导致产生土壤冷堆积,为此分析了土壤冷堆积产生的原因,以及近年来解决土壤冷堆积的一些研究方法。提出将冷却塔逆用与土壤源热泵联合运行,满足室内冷热负荷要求,使温度较低的地下水与环境中温度较高的空气进行换热,地下水升温后送回地下,以缓解北方地区土壤冷堆积问题;同时亦可在一定程度上改善局部热环境,并对冷却塔逆用进行了经济性分析。

Due to the problem of soil cold accumulation caused by the long-term operation of the soil source heat pump system, this paper analyzes the causes of soil cold accumulation in detail through reading a large number of literatures, as well as some research methods to solve the problem of soil cold accumulation in recent years. Inverse cooling tower with a combined with soil source heat pump is proposed to meet the requirement of indoor heat and cold load, and make the temperature lower groundwater and air to heat environment temperature is higher, back to the underground, groundwater used to mitigate the problem of soil cold accumulation in north China, at the same time, it also improve the local thermal environment to some extent. The economic analysis of inverse cooling tower is also carried out.
