[0002] In recent years, data centers have higher and higher requirements for temperature and humidity, and with the expansion of the design temperature range of data centers, the temperature of water supply has increased. When traditional mechanical refrigeration chillers produce high-temperature cold water, compared with indirect evaporative cooling chillers Production of cold water consumes a lot of electricity, and the cost of operation and maintenance is high. If only indirect evaporative cooling chillers are used to produce cold water, it will be subject to meteorological conditions. In case of continuous rainy days, traditional mechanical refrigeration chillers still need to be turned on to produce high-temperature cold water
