Can I combine a ventilation unit with an air conditioner?


An eternal question with a standard answer. Two in one will never be as good as two separate ones – that goes for coffee as well as for engineering solutions. The key is to understand that ventilation and cooling require very different amounts of air. 80-100 cubic metres per hour will be enough to ventilate a home, while 500-800 cubic metres will be enough for quality cooling. We do not recommend combining the two systems, also because if you want to transport cool air through the ventilation system ducts, it is likely that indoor humidity will condense on the duct walls. Therefore, the entire room piping should be thermally insulated. The recuperator does not have an active cooling element, but when the indoor air is cooler than the outdoor air, it will keep the room cool for some time by reversing the heat retention in winter.
