Where does the engine-driven air conditioner compressor pump refrigerant in vapor form?

The engine-driven air conditioner compressor pumps refrigerant in vapor form to the condenser. This is a critical step in the refrigeration cycle used in air conditioning systems. When the refrigerant leaves the compressor, it is in a high-pressure, high-temperature vapor state. Upon reaching the condenser, the refrigerant then releases heat to the surrounding air, which allows it to condense from a vapor to a liquid as it cools down. This transition is essential for the system's functionality, as the refrigerant must return to a liquid state before it can be cycled through the expansion valve and subsequently to the evaporator to absorb heat from the cabin air. The flow from the compressor to the condenser is fundamental to ensuring the proper operation of the air conditioning system and maintaining desired cabin temperatures.
