Product and functional description
Illustration
Illustration of the functional principle of the CDP 35/45/65:
Functionality of the
dehumidifier
CDP 35/45/65 is working in accordance with the condensation principle.
The humid air is drawn into the unit by one, two or three fans.
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 ex-
tracted. This extra heat corresponds to an approximate increase in temperature of 5 °C.
The repeated circulation of air through the unit reduces the relative humidity, giving
very rapid but gentle drying.
Fan control
When the dehumidifier is started by the hygrostat, the fan(s) are activated at the same
time as the compressor.
If continuous ventilation is required – i.e. independent of the dehumidification demand –
a bridge must be made between the terminals 25 and 26.
Compressor cont-
rol
The number of compressor starts is limited by a 6 minutes timer, which starts when the
compressor is switched on. The timer must have come to an end before the compressor
can be switched on again.
Each time the unit has been switched off on the main switch, by the built-in hygrostat
or by an external hygrostat, it will take 30 seconds before the unit can be switched on
again. This is a safety function protecting the compressor against overloading caused by
too high pressure in the cooling circuit at start up.
