Specifically, the method comprises the following steps:

1. and (5) circulating the working condition of the air conditioner. In the air conditioning season, the water pump 16 is stopped, the water inlet electromagnetic valve 4 and the water return electromagnetic valve 3 are opened, and due to the action of the check valve 14, the chilled water can only enter the heat exchange tube in the heat exchanger 7 after entering from the water pump 1 to exchange heat with fresh air passing through the heat exchanger 7 and then flows out from the water return tube 2, so that the temperature of the fresh air is reduced to a proper temperature, and the purpose of air conditioning is achieved.

2. And (5) circulating under an anti-freezing working condition. In the anti-freezing season, the water inlet electromagnetic valve 4 and the water return electromagnetic valve 3 are closed at the moment, the air-conditioning working condition circulation of the chilled water is cut off, and the chilled water is retained in the heat exchange tube of the heat exchanger 7 and the anti-freezing water circulation pipeline 11. When fresh air passes through the heat exchanger 7 and the temperature probe 18 detects that the air temperature is lower than a set value, the electric cabinet 10 starts the water pump 16 to operate, water flows in the anti-freezing water circulation pipeline 11 and sequentially flows through the water pump 16, the second vibration reduction pipe 15, the check valve 14, the stop valve 13, the heating pipe 17, the heat exchanger 7, the stop valve 13, the second vibration reduction pipe 15 and the water pump 16, and anti-freezing circulation is completed. Because the water flows fast in the heat exchange tube, the ice nucleus continuously impacts the tube wall and is continuously damaged and difficult to condense into ice, thereby realizing the aim of preventing freezing. Under the condition of extreme weather, the heating pipe 17 can be started to heat water, so that the water temperature is properly increased, and the auxiliary anti-freezing effect is achieved.
