Suppose that supply air temperature is -25°C. Ambient air temperature, where air handling unit is installed,
is +20°C. In this case, condensate may appear on the outer surfaces of the air handling unit when relative hu-
midity in room is in range from 23% up to 100% (from point where curves of outside and inside air temperatures
crosses till the maximum value).
In other case, suppose that supply air temperature is 0°C. Indoor air temperature where air handling unit
is installed is +20°C. In this case, condensate may appear on the outer surfaces of the air handling unit when
relative humidity in room is in range from 43% up to 100% (from point where curves of outside and inside air
temperatures crosses till the maximum value).
To avoid condensation on unit outer surface use following solutions:
1) There should be maintained a lower relative humidity in the room where air handling unit is installed;
2) Preheater should be installed to increase the supply air temperature
