Dehumidification
Dehumidification by superheating adaptation:
During dehumidification by superheat adaptation, the evaporation temperature falls beneath the dew point so
that a condensation is produced. The temperature control is not influenced by this. With low room loads and
as a consequence low compressor power, it can happen that the air is only slightly dehumidified.
Dehumidification with additional compressor speed increase:
To also dehumidify efficiently with low heat loads (compressor power) the compressor speed is increased
during dehumidification. To maintain the temperature the air must be reheated. If the electric reheat does not
suffice, the hotgas reheat is additionally switched on due to its start value.
The CyberLab function is activated by the following command:
By activating this special software option the following features come into force:
- the EC compressor (ICC) runs permanently.
- the electric reheat is controlled by PID factors.
by the following commands you can set the PID factors.
- for the EC compressor and the electric reheat there is a setpoint spread of 0,1 K if both components are
simultaneously in operation.
With a setpoint of e.g. 24,0°C, the EC compressor runs at 24,1°C and lower at minimum speed, the electric
reheat is switched off at 23,9°C and higher.
