4 Description of the System
The Combi Unit Genius realizes the complete building services for energy efficient buildings without water-based heating system.
Modern buildings are planned with thicker envelopes. Thus, a mechanical ventilation is more and more necessary. New buildings as well
as renovated buildings have higher insulation standards with less heating loads. Consequently, conventional heating systems are often
over-dimensioned.
Systemair provides with the Combi Unit
Genius a new designed heating system based on heating and cooling via ventilation ducts. This
can be achieved by temporarily increasing the volumetric flow in combination with an air-air/air-water-heat pump. This heat pump also
provides warm water.
Furthermore, planning and design of the building equipment can be minimized.

4.1.1 Heat Pump/Cooling Circuit
A steplessly controlled air-air heat pump heats in winter and cools in summer. The heat pump adjusts its performance according to the
requirements. This guarantees an energy efficient operation. Additional air is removed from the living area via a separate duct system
and led back after treatment (heating or cooling) to living and sleeping areas. This is a pure air heating/cooling system. The extract
system remains unaffected. An odour or mass transfer from the extract air rooms into the supply air is excluded.
The hot water generation with a 150 litres drinking water tank is ensured by an additional plate heat exchanger. This ensures hot water
comfort because water treatment works during all operating modes. The water will be heated or cooled to the desired temperature on
demand.
