How does a txv work

WebA TXV for air conditioning is pretty much the same as TXV for refrigeration. They both work off of bulb pressure that opens the valve and increases refrigerant flow to the coil. A combination of adjustable spring pressure and suction pressure work together to overcome bulb pressure to drive the valve closed to reduce refrigerant flow. WebJan 14, 2024 · The TXV now sees an evaporator outlet pressure of 52 psig underneath its diaphragm. The evaporator superheat would be: 37°F evaporator outlet temperature (bulb temperature) - 28°F saturated temperature (equivalent to evaporator outlet pressure) = 9°F superheat By no means should a service tech ever cap or close the external equalizer port …
