某物流中心低温粮库空调设计方案探讨

Discussion on Air Conditioning Design of Low Temperature Grain Depot in Huangshi Grain Logistics Center

本文以某现代化粮食物流中心低中温粮库制冷空调系统设计为例,介绍了热泵+冷却塔+主机热回收的节能空调系统方案。与常规空调系统相比,该空调系统既考虑了浅层地热能的开发利用,空调供冷、冷却水供热,也考虑了主机的热回收。初投资相比传统的谷物冷却机高,但运行费用较谷物冷却机低,且能制取宿舍及办公楼的日常生活热水,具有良好的节能性和经济效益。

Taking the air conditioning system design of low temperature grain depot in Huangshi grain modern logistics center as an example,this paper introduces the energy-saving air conditioning system scheme of ground source heat pump+cooling water heating+main engine heat recovery.Compared with the conventional air conditioning system,this system not only considers the exploitation and utilization of the shallow geothermal energy,cooling and cooling water,but also the heat recovery of the main engine.Compared with traditional grain chillers,the initial investment is higher,but the operating cost is lower,and it can make hot water for daily life in dormitory and office building.
