Central air conditioning system cold winter how to anti-freeze!

Winter and summer are the high-frequency areas of air conditioning, it is so that to ensure the normal use of central air conditioning in strict winter must take protective measures in advance.

How to judge the critical value of the weather for the central air conditioning system: under normal circumstances, the low temperature critical value of the central air conditioning system is 3 degrees Celsius, and once it is below 3 degrees Celsius, anti-freezing measures should be taken to prevent equipment damage and pipeline freezing.

The specific measures of anti-freezing work are summarized as follows:

1. Close the doors and Windows of the machine room to prevent cold air penetration and strengthen the inspection of the operation of the system equipment; Pay attention to the water temperature in and out of the unit, and focus on the status and protection of the equipment near the outside window and outdoor outdoor equipment.

1, it is recommended to adjust the fresh air conditioning box system to the minimum or close the system to reduce the heat load and reduce the heating pressure of the unit.

2. Check the insulation of outdoor equipment and pipes, paying special attention to the cooling water tower, water tank and water supply pipes to prevent freezing.

3, not put into use of the air conditioning system (including air conditioning auxiliary equipment: water tower, water pump, heat exchanger) water needs to be drained. If it cannot be emptied, the staff should regularly patrol and monitor, and take protective measures, and deal with ice in time.

4, the air-conditioning system of commercial office buildings is recommended for weekends and holidays, and the system pump must be kept running 24 hours a day and night, and strengthen the duty patrol.

5, the four control central air conditioning system is recommended to enable the system circulation pump to turn on the operation, keep the water circulation flow smooth, and strengthen the day and night duty inspection.

6, the data center air conditioning system operates in winter antifreeze mode, and the performance of the electric heating components of the cooling tower needs to be checked in advance according to the system configuration to keep it available. And always monitor the operating temperature of the cooling water system, and take effective anti-freezing measures in time.
