http://solutions.parker.com/Literature-10 WebThe TXV cannot control the superheat after the sensing bulb. Total superheat (measured at the condenser) should be 8-20°F. If the total superheat is below 8°F check the TXV sensing bulb for proper installation, good contact and insulation. If the total superheat is above 20°F check the evaporator superheat.

Webof refrigerant capillary tubes range from 0.5 mm to 3 mm and the length ranges from 1.0 m to 6 m.Several combinations of length and bore are available for the same mass flow rate and pressure drop. 1.2 Thermostatic Expansion Valve: Thermostatic expansion valve is the most versatile expansion valve and is most commonly used in refrigeration systems. WebOn the other hand, the capillary tube cannot be adjusted according to changing load conditions and requires the refrigerant charge to be held within close limits. Moreover capillary tubes are easily clogged by small particles that can affect the system efficiency or even interrupt its operation (Marcinichen, 2001).

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°.
