WebDec 9, 2024 · Before adding refrigerant, check the superheat reading at the low evaporator heat loading and see if it is normal. Normal evaporator superheats usually range between 5° to 10°F when the system is pulled down to a desired refrigeration space temperature and the evaporator is under a low heat loading. WebMany units have a charging chart, behind the name plate on the condensing unit, use this first. Charge by superheat for fixed metering devices, and use subcooling for TXV’s, if your not sure check the manufacturer documentation. None of this means ANYTHING if your airflow isn’t up to manufacturer specs. Same goes with proper system sizing.
