The cold water of the first plate heat exchanger 1 is connected to chilled water of a first temperature value, and the cold water of the second plate heat exchanger 2 is connected to chilled water of a second temperature value, which is smaller than the first temperature value.
When the air conditioner is cooled at a high temperature (namely, when the temperature acquired by the first temperature sensor 7 is higher), the water pump 5 is started, hot water passing through a load end (a measured piece) is driven into the hot water side of the first plate heat exchanger 1 through the first three-way valve control 3, heat exchange is carried out between the hot water and chilled water of the air conditioner at 7/12 ℃, and the load is cooled for the first time; the cooling water after heat exchange flows back to the water return end of the cooling pipeline through the second three-way valve 4;
