Hvac Wet Bulb And Dry Bulb

When air is at 100 relative humidity the dry bulb wet bulb and dew point temperatures are all the same.

Hvac wet bulb and dry bulb. Dry bulb temperature is a reading of the average molecular velocity of dry air but it does not take into account the actual heat content of the air or the evaporative cooling effect of the air. 1 16 of 103 results for wet bulb thermometer hvac amazon s choice for wet bulb thermometer hvac. The knowledge of only two of these values is enough to determine the state of the moist air including the content of water vapor and the sensible and latent energy enthalpy in the air. Wet bulb the lowest temperature that can be reached by the evaporation of water only measuring humidity.

Dew point the temperature to which the ambient air dry bulb must be cooled to reach 100 relative humidity saturation.
