WebJul 24, 2024 · If it is using a piston or other fixed metering device, you must refer to the manufacturer's superheat requirements or a superheat chart like the one below. If it is a TXV-type metering device, the TXV will generally attempt to maintain between a 5 – 15 ° superheat on the suction line exiting the evaporator coil (10 ° +/- 5 ° ). 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.
