The task of the condensing unit is to supply heating or cooling energy to the heat exchanger of the air conditioner, thanks to which the appliance is able to maintain the desired air parameters in the air-conditioned room. Inverter-type condensing units are equipped with an additional control module, enabling a universal outdoor unit to be connected to any Freon exchanger. This module provides continuous capacity adjustment of the unit, depending on the 0-10 V control signal. The condensing units are equipped with a complete, automatic system protecting against system overload and against the influence of unfavourable weather conditions, and to enable defrosting in the heating mode. These units operate efficiently and quietly and can be installed up to 75 m away from the air conditioning unit thanks to their modern design.
