If the temperature of the vapor is, let us say, 300°C; and if we transfer some heat from the vapor, the temperature may drop somewhat but no condensation will take place as long as the temperature remains above 100°C (for P = 1 atm).

Weband consequently there exists a vapor pressure. When a container containing water is open then the number of the escaping molecules is larger than the number of molecules coming back from the gaseous phase (Fig. 5.1). In this case vapor pressure is small and far from saturation. When the container is closed then the water vapor pressure above the WebApr 5, 2024 · Without knowing what the water vapor content of the return air is, we can’t predict the supply air temperature. Ditch the thermometer and invest in a hygrometer. That way, you can measure the moisture content of the air entering and leaving the unit, in addition to the ΔT, if you still want to hang on to that.
