Service Items: Air Conditioning Fluorination
When we determine that the system is blocked, I suggest that we deal with it in a cost-reducing way from simple to complex.
When the system is seriously dirty and clogged, we can choose to release the refrigerant, weld open the subcooling pipe group, and use high-pressure nitrogen to blow out the dirt. When releasing fluorine, we should pay attention to it is best to quickly open the copper cap of the rough stop valve under air conditioning and heating conditions. Allowing the refrigerant to spray out instantly can bring out the dirt in the system. When welding the subcooled pipe group, be sure to cool down the one-way valve.
Carbon chloride cleaning method
This method is used when dust enters the system or the refrigeration oil becomes mushy after the compressor burns. Carbon tetrachloride is corrosive and volatile, so it must be used when cleaning the system. The one-way valve and four-way valve must be welded off the compressor to avoid corrosion. You can use a vacuum pump as power to repeatedly clean the system pipelines. After cleaning, use high-pressure nitrogen to blow out the residual carbon tetrachloride, which will quickly volatilize under the action of nitrogen to reduce corrosion on the system.
Adding a drying filter method
After the two methods are successful, a drying filter needs to be added to the air conditioner return pipe to filter out the moisture in the system and the impurities and dirt in the refrigeration oil.
One-way valve reversing method
Often when the system is blocked, it is usually blocked in front or behind the capillary tube. We instantly turn on and off the power to the four-way valve to change the flow direction of the refrigerant and flush away the dirt blocked in the capillary tube. Allow the refrigerant to flow normally to achieve the purpose of cooling and heating.
Welding and baking method
When the system is oil-blocked and there is frost at the capillary, we can use gas welding to bake the frosted area to reduce the viscosity of the oil and allow the system to operate normally.
Freon is needed for the air conditioner to cool or heat normally. Therefore, if your air conditioner is not cooling or heating well, it means that your air conditioner needs to be added with fluoride. If the air conditioner is lacking fluorine, it will cause the air conditioner to be cooled or heated. Increased electricity consumption will also reduce the service life of the air conditioner.
