Description
The Carrier T111850057 Thermostatic Expansion Valve (TXV) is a refrigerant meter that regulates the amount of liquid entering the evaporator to maintain stable superheat conditions and efficient heat exchange. It operates using a temperature-sensing bulb and internal diaphragm that adjust valve opening based on evaporator outlet temperature and pressure, ensuring precise refrigerant delivery for optimal cycle balance. In HVAC systems it is used in air conditioning and heat pump units to improve cooling efficiency and protect the compressor from liquid refrigerant return. It is situated in the fluid line near the evaporator inlet and supports stable cooling performance, energy efficiency, and reliable system operation.
