WebWhen charging to the proper Superheat, you should have at least 5F, but not more than 25F subcooling with a fixed metering device. This indicates the proper size orifice and that the refrigerant will remain a liquid until meeting the orifice. If you have an undersized orifice, you will be starving the evaporator. WebThe metering device is responsible for feeding the proper amount of refrigerant to the evaporator coil. It is also know as the expansion device. Call Us! 602.975.3477
