由于档案保存的特殊性,需要全年恒温恒湿的环境,能耗很高。地源热泵系统采用土壤作为冷热源,是节约能源的有效手段。采用地源热泵系统能有效符合节能型档案馆建设的需要。而针对上海闵行区档案馆地源热泵系统冬夏冷热负荷不平衡问题,采用了热回收技术予以解决。模拟分析结果表明,在条件允许时,应适当加大埋管深度,同时采用热回收技术不会影响机组运行性能,并能缓解土壤热堆积问题。
Due to the special nature of the preservation of the file, the environment needs constant temperature and humidity all year round, and the energy consumption is very high. Ground source heat pump system using soil as a hot and cold source, is an effective means of saving energy. The use of ground source heat pump system can effectively meet the needs of building energy-saving archives. For Shanghai Minhang District Archives geothermal heat pump system winter and summer heat load imbalance problem, the use of heat recovery technology to be resolved. The simulation results show that when the conditions permit, the depth of buried pipes should be increased appropriately. At the same time, the heat recovery technology will not affect the operation performance of units and alleviate the problem of soil heat accumulation.
