[0040] Specifically, for the water circulation unit 200, under the power of the water pump 202, the high-temperature water enters from the water inlet interface 201 and is heat-exchanged through the heat exchanger 203, the high-temperature water is converted into low-temperature water, and the low-temperature water exits from the water outlet interface 204 and is delivered to the equipment needing cooling;

[0041] For the refrigeration circulation unit 300, the compressor 310 compresses the refrigerant into high-temperature and high-pressure gas and delivers it to the two parallel condensers 320, the condenser 320 cools and liquefies the high-temperature and high-pressure refrigerant vapor discharged by the compressor 310, the liquefied high-temperature refrigerant enters the heat exchanger 203 after being throttled and decompressed by the expansion valve to cool the high-temperature water, the liquefied low-temperature refrigerant is converted into gaseous high-temperature refrigerant after absorbing the heat of the high-temperature water and enters the compressor 310 again, forming a cycle.
