THERMAL EXPANSION VALVE FOR HVAC

摘要

A thermal expansion valve (TXV) for a heating, ventilation, and air conditioning (HVAC) system. The TXV includes a first inlet chamber configured to receive refrigerant from a condenser of the HVAC system. The first inlet chamber includes a first portion and a second portion with an aperture therebetween that fluidly connects the first portion and the second portion together. The TXV also has a first outlet chamber through which the refrigerant from the condenser exits the TXV. Bubbles in the refrigerant rise due to buoyancy and are trapped by the partition in the first portion of the first inlet chamber to restrict the bubbles from passing through the TXV to an evaporator of the HVAC system until the bubbles shrink to a size smaller than the aperture.
