As shown in fig. 2: the refrigerant output by the refrigerating mechanism 1 exchanges heat with water through a copper pipe in the heat exchanger 2, the cooled water enters the low-temperature water tank 5 through a circulating water return pipe 17, and meanwhile, the water in the low-temperature water tank 5 is pumped back into the heat exchanger 2 through a circulating water outlet pipe 18 under the driving of a circulating water pump 7; when the electromagnetic valve 10 is opened, water in the low-temperature water tank 5 is pumped into the heat exchange tube 3 to exchange heat with water in the normal-temperature water tank 4 and then returns to the low-temperature water tank 5.
As shown in fig. 3: two areas of the same external equipment have different requirements on temperature control, the first area 601 and the second area 602 are different areas on the external equipment 6, the working temperature of the first area 601 needs to be controlled to be 5-20 ℃, the working temperature of the second area 602 needs to be controlled to be 20-35 ℃, the first area 601 is cooled by adopting the low-temperature water tank 5 which is controlled to be 8-18 ℃ water, and meanwhile, the heat exchange pipe is utilized to exchange heat with the water in the normal-temperature water tank 4, so that the temperature of the normal-temperature water tank 4 is controlled to be 22-30 ℃, and the second area 602 is cooled.
