A metering device on a refrigerator is usually a capillary(cap)tube. It is a very small copper line located somewhere between the condenser coils (outside-hot) and the evaporator coils (cooling coils). It reduces the pressure of the refrigerant coming from outside as it enters the evap coils inside. Refrigerant cools under low pressure thus cooling desired inside area when air is blown across the cold coils. Think of a kinked garden hose and how on the spicket side of the hose the pressure is great, but on the other side the pressure is decreased. That is basically the purpose of a metering device.
There are four main parts of refrigerator. A compressor A condenser A Metering Device(capillary tube) An Evaporator
Yes, ideally only liquid refrigerant should enter the metering device to ensure proper operation. The metering device is designed to regulate the flow of refrigerant into the evaporator, and if vapor enters, it can lead to inefficiencies, reduced cooling capacity, or potential damage. Ensuring that only liquid refrigerant reaches the metering device helps maintain optimal system performance and reliability.
As the refrigerant exits the metering device
capillary tube
capillary tube.
Compressor, condensor, metering device, evaporator.
As a metering device you need uniformity
Compressor outlet to metering device inlet.
High pressure liquid
at the metering device before the evaporator
i have a 2002 jaguar x type and they said it needs a air metering device where is that at on the car
yes
