Description
The Carrier 340620-717 Thermal Expansion Valve (TXV) is a refrigerant metering technology that regulates the amount of liquid cooling fluid entering the evaporator coil based on system load conditions. It maintains proper superheat levels by adjusting flow in response to temperature and pressure changes within the refrigeration circuit. In HVAC systems, it is used in cooling and heating equipment to ensure balanced air vapor distribution stable ducting performance, and efficient heat exchange during operation cycles. It applies in residential and commercial air conditioning units where precise humidity control is required for reliable system effectiveness.
