How many bottles of refrigerant should be added to a car?

[StRose]

Adding refrigerant to a car typically requires 4 or 5 bottles. Refrigerant charging: Generally, it can be defined as adding refrigerant (Freon) to household cooling appliances, such as air conditioners and refrigerators, using professional tools to inject the refrigerant into the compressor. Methods for adding refrigerant to an air conditioner: 1. Weld an additional service pipe to the compressor's suction pipe for refrigerant charging. 2. Charge refrigerant through the high-pressure service pipe on the compressor. Prerequisites for refrigerant charging: 1. The air conditioner being serviced must meet its usage conditions and installation standards. 2. The maintenance tools and materials must be qualified. 3. Strictly follow the refrigerant charging procedures. Reasons for adding refrigerant: Freon is the medium that transfers heat in an air conditioning system. Without it, heat cannot be effectively exchanged, and the air conditioner cannot cool or heat. Therefore, when the air conditioner lacks refrigerant, symptoms may include poor cooling (or heating), no cooling (or heating), protective shutdown, water leakage from the indoor unit (sometimes spraying water), and ice formation on the indoor evaporator.
