Can fluoride be added when the air conditioner is cold?

1, the air conditioner can be fluorinated when it is cold.

2. Turn on the air conditioner. When fluoride is added in winter, it is necessary to use the method of heating and pulling the reversing valve line to force the air conditioner to enter the refrigeration state.

3. Connect fluorination equipment. After the air conditioner is started normally, connect the fluorination equipment from the process port on the low-pressure valve side of the outdoor unit.

4. Measure the pressure and add fluoride, observe the high pressure during heating in winter, and control it at around 1.7MP after the pressure is stable.

5. Dismantle fluorination equipment; Dismantle the fluorination equipment in the coke-making state and tighten the sealed receiver of the external machine; If the equipment is disassembled under heating, it will cause a lot of freon leakage.

6. Install the air conditioner after adding fluoride, and check the air conditioner suspected of leaking with detergent foam.
