How to Recharge Car Air Conditioning with Refrigerant?

[JackDella]

There are two methods to recharge a car's air conditioning system: high-pressure side charging and low-pressure side charging. High-pressure side charging involves liquid refrigerant, characterized by safety and speed, making it suitable for the initial charging of the refrigeration system. Low-pressure side charging uses gaseous refrigerant, which is slower and typically used for topping up. Precautions when recharging car air conditioning with refrigerant: 1. Avoid direct sunlight or stove heating of refrigerant containers to prevent accidents; 2. Prevent direct contact between refrigerant and human skin to avoid frostbite; 3. Avoid refrigerant accidentally entering the eyes to prevent blindness; 4. Once the refrigerant lines are opened or if there is a leak, the refrigerant will completely escape; 5. Refrigerant in gaseous form is heavier than air, so avoid repairing the air conditioning in trenches or low-lying areas to prevent suffocation, and ensure the work area is well-ventilated.
