Explain why the external equalizer line on a thermostatic expansion valve should always be installed after (downstream of) the thermal bulb.
What will be an ideal response?
To prevent superheat problems from internal leaks in the valve. If a TXV with an external equalizer line were to have an internal leak, very small amounts of liquid would vent to the suction line through the external equalizer line. If the sensing bulb for the valve were to have this small amount of liquid touching it, it would throttle toward closed because this would simulate a flooded coil.
