Double flow ventilation is a system that ensures air quality, through the extraction of foul air in wet rooms (kitchen, bathrooms, toilets, laundry rooms, …) and that simultaneously ensures the insufflation of new filtered air in the dry rooms (living room, dining room, bedrooms,…).
• In WINTER the new air recovers the calories from the foul air that we extract from the house, thanks to the presence of a heat exchanger ( 92 recovery), helping to maintain the temperature in the house.
When there is 5oC on the outside and 20o C inside, the new air enters 19oC.
• In SUMMER the new air that enters the house is cooled thanks to the stale air that we extract from the house, thanks to the presence of a thermal exchanger (92 recovery), avoiding the overheating of the house.
When there is 30oC outside and 21oC inside, the new air enters 22oC only, cooling in summer.
