How a thermal expansion valve works

Web27 de abr. de 2024 · Thermostatic Expansion Valves. Thermostatic expansion valves (TXVs) work as a type of throttling device and are one of the four essential components in a refrigeration cycle, along with evaporators, compressors, and condensers. As with other throttling devices, TXVs cause the refrigerant to expand as it flows, reducing the pressure. Web5 de nov. de 2024 · Place the sensing bulb in a glass of warm water or grip it in your hand. You need to raise the temperature of the sensing bulb to determine if the expansion valve is activating. One easy way is to simply drop it in a cup of warm water. Otherwise, you can simply hold the bulb in your hand throughout the duration of the test. [8]
