Superheat and subcooling calculator

Refrigerant — turns the gauges into saturation temperatures

Superheat

Evaporator pressure (bar g)Suction line temp (compressor) (°C)At the service valve on a split

Saturated evaporating temp

—°C

Total superheat

Suction (comp) − evaporating

—K

Condensing pressure (bar g)Liquid line temperature (°C)

Saturated condensing temp

—°C

Total subcooling

Condensing − liquid line

—K

Saturation data derived from reference equations of state. Always cross-check against calibrated gauges.
