How to Recharge Car Refrigerant?

[DiChristopher]

Methods for recharging car refrigerant: 1. Charge from the bypass hole of the compressor discharge valve, known as high-side charging, where refrigerant liquid is added. This method is safe and fast, suitable for the first charge of the refrigeration system, i.e., after leak detection and vacuuming. 2. Charge from the bypass hole of the compressor suction valve, known as low-side charging, where refrigerant gas is added. This method is slower and can be used for replenishing refrigerant in the system. Refrigerant is the working fluid used in refrigeration and air conditioning systems to transfer heat energy and produce cooling effects. In air conditioning systems, it is a substance that facilitates heat transfer through evaporation and condensation, commonly known as Freon.
