Sub-Cool System

Sub-Cool System Description







In the sub-cool A/C system (condenser integrated with receiver / dryer), the inside of the condenser is divided into the condensation part and the sub-cooler part, and the receiver / dryer is located between those. In the receiver / dryer, the refrigerant is separated into the vapor refrigerant and the liquid refrigerant. Only the liquid refrigerant is delivered to the subcooler part of the condenser. The refrigerant is supercooled by the sub-cooler part of the condenser.
