Question

Which type of metering device used on flooded evaporators opens to admit more liquid refrigerant into the evaporator when the liquid level in the evaporator drops?

a) Capillary tube
b) Thermostatic expansion valve (TXV)
c) Float valve
d) Automatic expansion valve (AXV)

Answer 1

The type of metering device used on flooded evaporators that opens to admit more liquid refrigerant into the evaporator when the liquid level drops is the Float valve.

Step-by-step explanation:

The type of metering device used on flooded evaporators that opens to admit more liquid refrigerant into the evaporator when the liquid level drops is the Float valve. The float valve is a mechanical valve that controls the flow of liquid refrigerant based on the liquid level in the evaporator. When the liquid level drops, the float valve opens to allow more liquid refrigerant to enter the evaporator.
