Description
The Heatcraft Refrigeration 29341711 Thermal Expansion Valve (TXV) is a refrigerant metering system used to control the amount of airflow entering the evaporator based on cooling demand. It operates using a sensing bulb and diaphragm system that reacts to temperature and pressure changes, adjusting flow to maintain proper superheat for efficient heat exchange. It is mounted at the vaporizer inlet with secure refrigerant line connections and proper lamp placement for accurate detection. Used in HVAC systems such as air conditioners and freezer units, it optimizes cooling performance that improves energy efficiency and ensures stable and reliable system operation.
