The thermostatic expansion valve ( TXV ) is a precision device, which is designed to regulate the rate at which liquid refrigerant flows into the evaporator. This controlled flow is necessary to maximize the efficiency of the evaporator while preventing excess liquid refrigerant from returning to the compressor (floodback).
A thermal expansion valve (often abbreviated as TEV, TXV , or TX valve ) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator thereby keeping superheat, that is, the difference between the current refrigerant temperature and its saturation temperature at the current. Lennox has seen an increase in TXV.
