Air cooling power from flow and delta T
Estimates sensible air cooling power from volumetric flow rate and temperature difference.
Magnus dew point
Calculates a helper dew-point estimate for humid air from temperature and relative humidity; it does not replace HVAC condition validation.
Humidity ratio from temperature and RH
Calculates humidity ratio from temperature, relative humidity, and atmospheric pressure using the Magnus approximation.
Stull wet-bulb temperature
Estimates wet-bulb temperature with the empirical Stull equation over its limited temperature and RH range.
Two-stream moist-air mixing
Mixes two dry-air streams by humidity-ratio and moist-air enthalpy balances.
Cooling water flow rate from power
Calculates cooling-water volumetric flow from power, density, specific heat, and temperature difference.
Total cooling load from sensible and latent load
Sums sensible and latent cooling load without automatic equipment sizing.
Condensate rate from humidity-ratio difference
Calculates condensate mass flow from dry-air mass flow and humidity-ratio decrease.
Cooling energy from power and time
Calculates cooling energy from cooling power and time using the same relation as the thermal calculator.
Full psychrometrics
Moist-air properties with the Buck equation: RH, W, dew point, wet bulb, vapor pressure, enthalpy, density, comparison and air-stream mixing.
Interactive psychrometric chart
Tdb-W chart with saturation boundary, RH curves, enthalpy and specific-volume lines, state points and HVAC processes.
