Clean Good Quality Air
Many of us spend at least half of our time at home in our houses and apartments. By providing good quality air at home we not only increase the well-
The purpose of ventilation is to provide clean good quality air by removing the stale, polluted air from our homes. The main task is of course to ensure that the indoor air is healthy and safe to breathe. Ventilation today is also about energy and saving energy costs by adding heat recovery and/or renewable energy to the ventilation system.
What is Mechanical Ventilation Heat Recovery (MVHR)?
A human being usually consumes about one kilogram of food and two litres of water each day -
Heat recovery is a process of continuously preheating incoming cool supply air by warming it with the outgoing exhaust air. Warm air is not simply exhausted through the open window but transfers most of its heat to supply air in a highly efficient heat recovery exchanger before being exhausted. At no time do the airstreams mix as the heat radiates through the plates of the exchanger.
Stale air is contaminated with humidity, toxins and smells extracted from the kitchen, bathroom and toilet. Outlet grilles in toilets and wet room areas, such as the bathroom, en-
Fresh air is fed directly from outside into the ventilation system through a filter. The heat taken from the extracted air is used to warm the fresh filtered air in the exchanger and then flows through ducting. By undercutting doors and fitting transfer grilles fresh air circulation is ensured throughout the dwelling.
Saving Energy with MVHR
The level of effectiveness in saving energy depends on a number of highly variable and difficult to estimate factors. These are the level of air tightness in a home, the way the home is heated, the heat energy saved by the system, the energy used by the system, the type and cost of fuel used to heat the home and the cost of electricity used to run the system. MVHR systems are designed to run 24 hours a day, seven days a week, 365 days a year. Quite simply they have to be quiet in operation and acceptable to the occupants.
