Simple operation method and judgment method for adding fluoride to central air conditioner

The central air-conditioning system is different from the general hanging and desktop air-conditioning. The central air conditioning system consists of a cold and heat source system and an air conditioning system. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system. The current central air-conditioning system is divided into service system and water system. Two different working modes are very popular. Of course, if it is not cooling, most of the reasons are also the lack of refrigerant. Here is a brief introduction to some of the operation methods of central air-conditioning fluoride.

1. How to judge the lack of fluoride in central air conditioners

The method of judging the lack of fluoride in central air conditioners is basically the same as that of general air conditioners. Freon is used as an air conditioning refrigerant to transfer heat Medium. Played an irreplaceable role. Once the air conditioner is uncooled (heated), the indoor unit leaks water (sometimes it sprays water), and the evaporator of the indoor unit freezes. Generally, it can be judged that the central air conditioner is lack of fluorine.

Second, the specific method of adding fluoride to the central air conditioner

1. Use a new copper tube as a suitable charging connection tube, and connect it to the system The filling valve and the joint on the media bottle;

2. When connecting a full bottle of refrigerant with the connecting pipe, it should be purged. The faster the bottle change time is, the better, and the refrigerant can be reduced. Loss;

3. Measures should be taken to prevent moist air from entering the system during the filling process;

4. The filling volume should be correct and appropriate, and refrigerant liquid can be seen in the evaporator sight glass Position;

5. Observe the liquid level and make a record after the initial charge of refrigerant;

6. During the process of pumping refrigerant or refrigerant filling, the refrigeration and cooling pumps should be operated ，Let the cooling water and chilled water circulate to avoid the cold liquid in the tube bundle from freezing and bursting of the copper tube. When the refrigerant charge is more than 2/3, the host can be turned on and charged during operation;

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

The above briefly introduced how to judge the lack of fluoride in central air conditioning and the specific method of adding it. For Central Air users. It is very necessary to know some information about adding fluoride to the air conditioner, which can not only ensure the effect of the central air conditioner in your home, but also effectively extend its service life.
