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.
