eng.refrigerant-superheat-subcool Calculator
Calculates refrigerant superheat at the evaporator outlet and subcooling at the condenser outlet from pressure-temperature measurements. Target superheat of 10–15°F and subcooling of 10–15°F at the service valves indicates correct refrigerant charge and system operation.
Inputs
T Sat Evap C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
T Suction C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
T Sat Cond C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
T Liquid C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).

subcooling at condenser exit (°C)
The value at the specified point or condition.
superheat target range
The difference between the maximum and minimum values.
subcooling target range
The difference between the maximum and minimum values.
