WebFeb 17, 2024 · 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). WebThe idea of a TXV is to maintain a fixed superheat (how much heat the cool gas contains) over all conditions. In HVAC, they usually shoot for about 15Â°. That means if the refrigerant enters the coil at 40Â° it leaves around 55Â°. On higher SEER equipment, the entering temp is probably more like 45Â° to 50Â°. bts ama performance 2021WebJun 25, 2024 · Likewise, a capillary tube restricts the flow by using a very long pipe or tube in order to create the correct amount of flow.
