The refrigeration function of air conditioning is inseparable from the refrigerant. In the use of air conditioning, the refrigerant will gradually consume and volatilize, so it may be necessary to add refrigerant in the follow-up.

How often does the air conditioning refrigerant be added? 

How often the refrigerant of air conditioning is added depends on the air conditioning itself. Some air conditioners do not need to be added once for seven or eight years, and some air conditioners need to be added for two or three years. As long as air conditioning refrigeration is normal, it is necessary to pay attention to the cleaning of air conditioning after a long time, dust will also affect refrigeration.

How to add air conditioning refrigerant?

1. When the air conditioner is fluoridated in summer, the air conditioner can be directly operated in the refrigeration mode. Because in the heating state, the air conditioner can not be fluoridated operation, so in the winter, the air conditioner should be forced to enter the refrigeration state.

2. Connect the fluorine equipment with the liquid hose first connected to the refrigerant steel cylinder valve, and then connected to the liquid cutting at the end. The surface cutting is opened, and the other end of the liquid cutting is connected with the liquid adding nozzle of the coarse tube valve on the outdoor unit of the air conditioner with the liquid adding hose. At this time, there is refrigerant gas in the pipe, loosen the steel cylinder valve joint to release some gas (exhaust air) and then tighten. The air conditioner sets the refrigeration mode and starts running. Invert the fluorine refrigerant cylinder and open the valve to allow the refrigerant to be sucked into the air conditioning system through the low pressure valve. Note that the air and dirt in the fluoridated tube must be discharged during this process.

3. pressure measurement fluorine observation of low pressure in summer, the ambient temperature of about 32 degrees Celsius, the pressure control at about 0.45mp; In winter, the high pressure during heating was observed, and the pressure was controlled at about 1.7mp after stabilization.

4. remove the fluorine equipment in the system of ling state to drop the fluorine equipment, tighten the external secret seal, air conditioning refrigeration liquid added successfully. Note that if the equipment is dropped in the heating state, it will cause a large amount of fluorion leakage, which is easy to reduce the efficiency of air conditioning.
