In the scorching summer, air conditioning is an indispensable part of people's lives. Recently, however, some regions have begun to use fluorine compounds to replace traditional refrigerants - chlorine, bromine, and iodine - in order to save energy and reduce the impact on the environment. So how do you add fluoride yourself at home? Below is an introduction for everyone.

Specific methods for adding fluorine to air conditioners

Generally, we may use low-pressure fluorination and static fluorination for air conditioning. If the family adds fluoride itself, the specific steps are as follows:

1. Materials required: A set of air conditioning fluorination tools, and a bottle of refrigerant.

2. Turn on the air conditioner and operate it in refrigeration mode (if refrigeration cannot be turned on in winter, the temperature sensor can be placed in hot water). Connect the fluorine adding pipe to the external machine interface (there are two copper pipes, and the interface of the thick pipe is required for adding liquid), so that it is in a low pressure state.

3. Open the refrigerant cylinder valve and the three-way valve of the pressure gauge (note: the cylinder should be placed upright, not upside down), start adding fluorine, and fill it for a period of time (time can be controlled by yourself, different air conditioning filling times vary). Close the cylinder valve, and check the pressure gauge reading (the reading will slowly fall back and finally remain stationary). Generally, it needs to be added to 0.4-0.5MPa in summer, and around 0.3MPa in winter.

Note: If the refrigerant has leaked, it can be quantitatively added with fluorine. According to the set filling amount of the air conditioner, use a scale to add fluorine according to the standard filling amount. The refrigerant type and filling amount are indicated on the external unit, and you can check them yourself.

In addition, if the fluorination of air conditioners is usually completed by professionals, the operation is also very simple. When adding freon to the air conditioner, first open the bottle containing freon slightly to allow the freon in the bottle to slowly flow out, then quickly connect the fluorine pipe to the air conditioner's fluorine filling port and tighten it. After that, the Freon in the fluoride bottle will flow into the air conditioner.

How and how much fluorine should be added to the air conditioner

Invert (upright) the fluorine refrigerant steel cylinder, open the cylinder valve, allow the refrigerant to be sucked into the air conditioning system from the low-pressure valve, control the liquid filling gauge, and do not add the liquid too quickly. (In summer, the low-pressure pressure should not exceed 0.4-0.5MPa) Complete the fluorine filling operation.

Before adding Freon to the air conditioner, we need to prepare the tubes for adding fluorine, as well as the Freon cylinder, including a pressure gauge. After preparing these, we need to turn on the air conditioner and adjust it to the refrigeration mode. Then, we need to connect the fluoride flushing pipe to the refrigerant cylinder, and at the same time, we need to exhaust the air in the hose. To take advantage of the pressure difference between them, we need to start injecting Freon gas. While filling with Freon, carefully observe the pointer changes of the pressure gauge.

Precautions for adding fluorine to air conditioners

In fact, Freon is a kind of refrigerant, and the role of Freon added to the air conditioner is to ensure that the air conditioner can operate normally. If there is no Freon in the air conditioner, the air conditioner cannot operate normally.

When adding freon, it is necessary to invite professional personnel, wear professional anti-static work clothes, and install standardized operating procedures to add freon to the air conditioner. When adding freon, there must be no open flames, otherwise there may be risks.
