Use this chart when matching coil with an outdoor unit with a different nominal capacity than. (Note that in most cases, equipment designed for R-22 cannot use R-410A because of this difference in operating pressures, so retrofitting an existing R-22. Size a fixed metering device piston based on the condenser specifications. ” This article offers an overview of some of the issues related to R-22 and -410A in the field: operating pressure differences, oil characteristics, and temperature glide. ADP evaporator coils are designed for use with condensing units or heat pump units.
