Inverter
The following drawing shows a schematic view of the inverter principle:
Inverter Features
The inverter provides the following features:
The regulating capacity can be changed according to the changes in the outdoor
temperature and cooling / heating load.
Quick heating and quick cooling
The rotation speed of the compressor is increased when starting the heating (or cooling).
This enables to reach the set temperature quickly.
Even during extreme cold weather, high capacity is achieved. It is maintained even when the
outdoor temperature is 2°C.
Comfortable air conditioning
A fine adjustment is integrated to keep the room temperature constant.
Energy saving heating and cooling
Once the set temperature is reached, the energy saving operation enables to maintain the
room temperature at low power.
Frequency Limits
The following functions regulate the minimum and maximum frequency:
