In this video, we break down the metering device and the important role it plays in the refrigeration cycle. You’ll learn how the metering device controls refrigerant flow, creates the pressure drop that allows refrigerant to boil in the evaporator, and helps the system absorb heat properly. We also explain the difference between common metering devices like TXVs and fixed orifice systems, along with how metering problems can affect superheat, system performance, and overall operation.
This is a practical training video for HVAC technicians and students who want a better understanding of refrigerant control, system efficiency, and field diagnosis.
