(engineering)

A device for quickly computing certain psychrometric data, usually the dew point and the relative humidity, from known values of the dry- and wet-bulb temperatures and the atmospheric pressure.

Since ASHRAE standard 90.4 lists wet-bulb temperature as the secondary parameter for the calculation of MLC when no waterside economization is present in the system, the wet-bulb temperatures were calculated using available data with VTAS's built-in psychrometric calculator. The calculator was developed using ASHRAE's Handbook (ASHRAE 2002) and has been verified for a dry bulb temperature range of -30[degrees]C to 50[degrees]C using two online psychrometric calculators (UIGI and SugarTech).
