Problems & Solution
The Problems
The down-side of these measures is that our homes have become, in effect, sealed boxes with little or no replenishment of the air, especially in the bedrooms. This leads not only to reduced oxygen that we need to breathe, but also contamination build-up such as, carbon monoxide from gas cookers and heaters, cigarettes, vapour from paint and biological pollutants like house dust mites.
Dust
All rooms in a house will have variations on these particle types within them which may aggravate certain allergic symptoms for those that suffer from dust allergies or asthma.
Odours
There are many types of odours around the average household, the following are some examples:
- Pets and their food
- Kitchen waste
- Food smell
- Human waste and body odours
- Cigarette smoke
- Solvents (glue, cosmetics, etc)
- Cleaning products
- Baby waste and vomit odours
Pollution
Pollution is associated with noxious gases from central heating systems, cookers, formaldehyde (paint) and cigarette smoke. Lack of ventilation exacerbates these problems.
Water vapour generated within our homes creates the all too familiar streaming windows leading to mould and fungus problems. Opening windows does not help as it is an uncontrollable means of ventilation which leads to wasted energy and an increase in costs, not to mention the security risks, noise and traffic pollution in highly populated areas.
“A controlled filtered ventilation system that costs little to run (as low as 60 watts), has low maintenance, is easy to operate, should be able to recover energy from the extracted air and most important should be easy to install.”
The Solution - HRV from Space Air
The Daikin (Heat Recovery Ventilation) system recovers heat energy lost through ventilation and holds down room temperature changes caused by ventilation, thereby maintaining a comfortable and clean environment.
