Vehicle refrigerant recovery and recharge are essential processes in automotive air conditioning systems. During refrigerant recovery, the refrigerant is carefully extracted from the system to prevent environmental damage. This involves evacuating the system, storing the recovered refrigerant in specialized containers, and potentially recycling it for future use. On the other hand, refrigerant recharge involves inspecting the system, removing any contaminants or air, adding the correct amount of refrigerant, conducting leak tests, and verifying the system's performance...
