Fresh air in older houses
Ventilation is about replacing old used air with new and fresh air. The fact that this air exchange takes place is essential for a healthy indoor climate. In many older homes, new windows have been installed with effective sealing against the wall structure. The apartments' air vents are closed to avoid cold draughts, dirt and noise. The result is airtight residential buildings with inadequate ventilation. This increases humidity in the apartments, which in turn increases the growth of mould and mites, as well as the excretion of contaminants from building materials and décor. Another problem is condensation on windows and cold wall surfaces. Houses built from blue concrete often have a dangerously high radon content in indoor air. Blue concrete was used in the years 1929-1975, which means that many houses are affected and need to be fixed. By improving ventilation and thereby increasing air turnover, radon levels can be significantly reduced.
Extraction and central extraction systems
The used air in a home is sucked out via a kitchen fan in the kitchen, and vents in the toilet/bathroom. Easy-Vent is placed in other rooms such as the living room and bedroom. Here, new air is supplied and preheated. The fresh air flows through the home, capturing pollutants generated indoors on the way to kitchen fans and exhaust vents.
How Easy-Vent works for existing radiators
Outdoor air is directed through the façade grille and duct into the air chamber mounted on the wall behind (model Mini below) the radiator.
At the entrance to the chamber there is a filter that prevents pollen and pollutants from entering with fresh air. The filtered air flows into the air chamber and is then directed up the back of the radiator. In contact with the warm radiator surface, the air is effectively preheated before being discharged at the top of the radiator. Draught-free and silent.
Easy-Vent increases the power of the radiator. Forced convection combined with a large temperature difference between the radiator and the outside air provides a highly efficient heat transfer to the air.
Easy-Vent is located behind the radiator in living rooms and bedrooms
Uteluft ledes inn i et luft-kammer via en kanal i fasadeveggen. I luft-kammeret filtreres uteluften og varmes opp av radiatoren. Den rene og oppvarmede friske luften strømmer inn i rommet på toppen av radiatoren. Trekkfri og lydløs. Hjemmets "gamle" brukte luft suges ut via kjøkkenvifter på kjøkken og ventiler på toaletter/bad og noen ganger i skap.
