Two calculations engineers reach for every day, run by the same code HVAC Builder solves systems with. No account needed.
Dry bulb plus wet bulb or relative humidity, at any altitude — to humidity ratio, enthalpy, dew point, density and the rest, on ASHRAE's relations with the IAPWS-IF97 saturation line.
Any of the catalog's compressor maps — thousands of published AHRI 540 polynomials — evaluated at your evaporating and condensing temperatures: capacity, power, COP, mass flow, and whether the point is inside the manufacturer's envelope.
Want the whole machine? Open the builder — it solves a coil, a compressor and a condenser together, and runs them against a year of weather.
