WebThis can be demonstrated on the psychrometric chart. Dehumidification and sensible cooling occur frequently in air conditioning systems. Air that pasess over cooling coil will often cool to the point that water vapor condenses out so that the air is both cooled and dehumidified. The sensible change is the horizontal line as shown here. WebA psychrometric chart is a clever chart that can be used to estimate psychrometric properties for a given air condition. Laminated charts can be used to plot out processes and given a visual representation of the effects of cooling, heating or humidification. Such charts are normally produced for standard air pressure (101325Pa) and so are limited.
