Air replacement ventilation system for rooms - includes fresh air artificial breather with the capability of extracting heat from exhaust air

摘要

There is timed phasing of heat storage from the exhaust air (12) and heat dissipation through the fresh air (14). - Intake air (15) and exhaust air (12) are led through the housing (3) of a fresh air breather, but not at the same time. In phase I warm used air is discharged into the open by means of a mechanical ventilator (4) through a cold heat storage mass (5), and the cold heat storage mass (5) is subsequently heated.
