WebIf the cooling coil is 100% effective, then the exit temperature of air will be equal to the coil temperature. However, in practice, the exit air temperature will be higher than the cooling coil temperature. Figure below shows the sensible cooling process O-A on a psychrometric chart. The heat transfer rate during this process is given by: WebAn average cooling coil of four to six rows will produce an air-leaving condition of approximately 90 percent RH.

WebCooling tower, air washer and spray dehumidifier nay be expressed as examples of direct con tact heat and mass transfer between the moist air and water. At the cooling and dehumidifying coils, indirect or induced heat and mass transfers occurs. In order to obtain thermodynamic properties of moist air, psychrometric tables and equations are used. everton in the community visionWebThis 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.
