摘要:

 以寒冷地区某医院综合楼为例,通过分析蒸发冷却空调系统供冷量与建筑冷负荷之间的关系,提出了蒸发冷却与机械制冷联合供冷的双温冷水系统,以及系统运行策略。对比分析结果显示,空调系统优化运行后,可节省耗电量36.4%,运行节能潜力较大。

Abstract:

Taking a hospital project in cold zone as an example, by analysing the relationship between the cooling capacity and the cooling load for the evaporative cooling air conditioning system, proposes a dual-temperature chilled water system combining evaporative cooling and mechanical refrigeration, as well as system operation strategies. The comparative analysis results show that the power consumption can be saved by 36.4% after operation optimization, and the operation energy saving potential is great.
