Shenzhen Haier central air conditioning: what should we pay attention to when adding fluorine to central air conditioning

   central air-conditioning It has become our essential household appliances. Now most of the air conditioners used in our homes are fluoride systems. The lack of fluorine in air conditioners will lead to poor cooling (heating) effect, protective shutdown, water leakage (sometimes water spray) of indoor units, and freezing of internal evaporator; Serious will also reduce the service life of air conditioning or waste of electric energy and so on, so we should timely add fluorine to the central air conditioning, so what should we pay attention to?


Precautions for adding fluorine to central air conditioner:


1. When the connecting pipe is used to connect the full bottle of refrigerant, it should be blown. The faster the bottle is changed, the better the refrigerant loss can be reduced;


2. Use a new copper tube as a suitable charging connecting pipe to connect the filling valve on the system and the connector on the medium bottle;


3. The filling amount should be correct and appropriate, and the refrigerant level can be seen in the evaporator mirror of central air conditioner;


4. In the process of refrigerant pumping or refrigerant filling, the freezing and cooling pump should be operated to circulate the cooling water and chilled water, so as to avoid cracking the copper pipe due to the freezing of cold liquid in the tube bundle. When the refrigerant filling amount is more than 2 / 3, the main engine can be started to charge during operation;


5. The liquid level should be observed and recorded after the initial filling of refrigerant;


6. When the pressure and temperature balance is reached between the condenser and the evaporator, check the refrigerant level (this time is generally more than 4 hours after the compressor and water pump stop running)


7. Take measures to prevent moist air from entering the system during filling;
