How to Recover Liquid Refrigerant From an Air Conditioning System?

Explanation:

To recover liquid refrigerant from an air conditioning system, you must connect a hose to the system's liquid line. The recovery process involves extracting the refrigerant in its liquid state so it can be reused or properly disposed of. The evaporator is the component that converts liquid refrigerant into gas by absorbing heat from the environment. Conversely, the condenser is responsible for converting gas back into liquid, as it releases heat to the surroundings (the process of condensation).

When the gas refrigerant is compressed and forced into the condenser coils, its temperature is higher than that of the room, causing heat transfer to occur and the gas to condense into a liquid. The liquid refrigerant then travels through a pressure-reducing valve and returns to the outdoor evaporator coils, becoming cooled by expansion.
