Copeland Comfort Control (Alco) 055187 Thermal Expansion Valve(TXV) R-22 5' CAP 5-1/2 HC HFES

The Copeland Comfort Control (Alco) 055187 Thermal Expansion Valve (TXV) is a refrigerant metering component used to regulate liquid refrigerant flow into the evaporator based on temperature and pressure condition. It is installed in the refrigeration circuit where it maintains proper superheat by adjusting refrigerant delivery according to evaporator load changes. The R-22 5' CAP 5-1/2 HC HFES specification defines refrigerant compatibility, capillary length, and charge type for accurate system matching. In HVAC systems, it improves cooling performance by balancing refrigerant flow enhancing heat transfer efficiency, and supporting stable compressor operation under operating conditions.
