Dew point control

During SUMMER operating mode, the mixing valve work set

modified for the dew point control.

The dew point is the temperature at which a mass of air must be cooled at constant pressure, until it is saturated (i.e.

when the percentage of water vapour reaches 100%) and therefore can start to condensate if it should lose further

heat.

This would lead to the formation of dew on the cooled surface, thus compromising the integrity of the controlled

environment.

The dew point is calculated on the basis of the temp
