RESIDENTIAL VENTILATION – DO YOU KNOW WHAT KIND OF VENTILATION YOUR RESIDENCE HAS?
Natural ventilation used to be common both in houses and larger buildings in earlier days. Deaeration happens naturally by hot air beeing lighter than cold air, and thus will rise up through the air ducts. Fresh air will be supplied through poorly isolated doors, windows or vents.
Mechanical ventilation means there is an engine somewhere in the building that pushes or draws air from the kitchen (or other rooms). Within this category, there are several types of ventilation. We will look at the different types of mechanical ventilation for houses.
Basic Ventilation
The engine is in the ventilator above the oven in the kitchen. The most common solution in Norwegian homes. Fresh air is supplied through doors, windows or vents. All ventilators from «Røroshetta» are customized for this.
RESIRCULATION
The air is purified through a carbon filter and then brought back to the kitchen. This is common where the air stream can not be led out into fresh air. The carbon filter must be changed or cleaned on a regular basis. Every 6 months should suffice. Most ventilators from «Røroshetta» are customized for this.
BALANCED VENTILATION
An engine sucks out the «old» air and brings new, fresh air in. In combination with a heat recovery system, heat from the indoor air is used to warm up the cold fresh air from outside.
CENTRAL VENTILATION – HOUSE
The engine is a self maintained unit placed in a closet (closet fan), inside the «Røroshetta», in the attic (attic fan) or on the roof (roof fan).
CENTRAL VENTILATION – BUILDING
Each apartement can adjust their own engine from the unit in the kitchen. A ventilation duct from the bathroom or scullery can also be connected.
COMMON VENTILATION
A powerful engine sucks out air from all the apartements in the building at the same time. Each resident can easily adjust their own ventilator by opening or closing a vent in their kitchen fan.
EXTERNAL ENGINE
An external engine is recommended if the ventilation air ducts are very long. This kind of external engine will only suck out air from the ventilator in the kitchen, and must not be confused with «central ventilation» that provides ventilation from several rooms. You can limit noise from the kitchen ventilator by placing the engine on the roof or in the attic.
