Sensible Cooling with Dehumidification

In this process the dry-bulb temperature and the moisture content of air are decreased. The heat in the condensed water is normally very small relative to the total cooling load therefore the load on the cooling coil can be approximated as:

Dehumidification can only occur, if the coil surface temperature is blew the dew-point temperature of the entering air stream.
Apparatus dew-point temperature (ADP) is defined as the average coil temperature at air condition C. Where C is the intersection of the saturation line and the straight line through conditions A and B on psychrometric chart. Related topic:
