Description Of Function; Technical Data - Dantherm CDF 35 Service Manual

1. Description of function

CDF 35 and CDF 45 are working in accordance with the condensation principle. The humid air is drawn
into the unit by a fan. When passing through the evaporator the air is cooled down to below dew point
and water vapour is condensed into water, which is drained away. The now dry air is then passed over the
condenser coil where the air is heated. As a result of the released evaporator heat and the working energy
of the compressor being turned into heat energy, more heat is returned to the air than was previously
extracted. This extra heat corresponds to an approximate increase in temperature of 5ºC. The repeated
circulation of air through the unit reduces the relative humidity, giving very rapid but gentle drying.
