Condensing / Evaporating Temperature Calculator

Estimate the saturated condensing temperature (T_cond) and evaporating temperature (T_evap) of a refrigeration circuit. Three modes: (1) from coil approach — T_cond = T_ambient + condenser ΔT approach, T_evap = T_medium − evaporator ΔT approach; (2) from measured saturated pressures — given P_cond and P_evap for a known refrigerant (R-22 / R-134a / R-410A), invert the Antoine fit; (3) from subcooling & superheat — T_cond = T_liquid − SC, T_evap = T_suction − SH. Temperature in °C/K/°F; pressure in bar/MPa/kPa/PSI absolute or gauge (atmospheric default 1.01325 bar). Results reported in °C.

Parameters

NameTypeRequiredDescription
refrigerantselectNoRefrigerant. Used only in 'from saturated pressures' mode.
modeselectNoEstimate method: coil approach, measured saturated pressures, or subcooling/superheat.
tAmbientnumberNoHeat-sink (ambient entering the condenser) temperature, in the selected Temperature Unit. Used in 'from coil approach' mode.
tMediumnumberNoCooling-load medium temperature entering the evaporator (air or water), in the selected Temperature Unit. Used in 'from coil approach' mode.
condApproachnumberNoCondenser approach ΔT = T_cond − T_ambient (K or °C). Typical air-cooled 8–15 K, water-cooled 4–7 K.
evapApproachnumberNoEvaporator approach ΔT = T_medium − T_evap (K or °C). Typical DX air 8–12 K, chilled water 4–7 K.
pCondnumberNoMeasured condensing (high-side) saturated pressure, in the selected Pressure Unit. Used in 'from saturated pressures' mode.
pEvapnumberNoMeasured evaporating (low-side) saturated pressure, in the selected Pressure Unit. Used in 'from saturated pressures' mode.
tLiquidnumberNoLiquid-line temperature after the condenser, in the selected Temperature Unit. Used in 'subcooling & superheat' mode.
subcoolingnumberNoSubcooling SC (K or °C) = T_cond_sat − T_liquid. Used in 'subcooling & superheat' mode.
tSuctionnumberNoSuction-gas temperature at the compressor inlet, in the selected Temperature Unit. Used in 'subcooling & superheat' mode.
superheatnumberNoSuperheat SH (K or °C) = T_suction − T_evap_sat. Used in 'subcooling & superheat' mode.
tempUnitselectNo—
pressureFormselectNo—
pressureUnitselectNo—
atmnumberNoLocal atmospheric pressure in bar (0.5–1.5, gauge↔absolute conversion). Default 1.01325 bar.
