The most important benefit of a domestic ventilation system with heat recovery is the positive effect on the health and well-being of the residents. A ventilation system also helps to save heating costs. The better the ventilation is geared to demand, the greater the benefit.<\/p>

The air we breathe is our No. 1 foodstuff. People who suffer from allergies in particular benefit considerably from an air supply with few pollutants. Fresh outdoor air contains far fewer airborne substances that can endanger health than “normal” indoor air.<\/p>

The treatment of outside air through filtration also helps to improve the indoor air. Replacing polluted indoor air with fresh air is therefore extremely sensible. All properly designed ventilation systems make a significant contribution to health.<\/p>

Just as important for a healthy indoor climate is the use of building and operating materials with the lowest possible emission of pollutants.<\/p>

A modern, airtight building has very good thermal insulation. It then loses more heat through ventilation processes than through the components. If you, as the resident of a house, prevent inefficient tilt ventilation, you can achieve significant energy efficiency improvements in the building heat supply through proper ventilation behavior.<\/p>

A sufficiently comfortable exchange of indoor air for fresh air can be achieved with ventilation systems. Systems with heat recovery are able to provide a significant proportion of the building’s heat supply.<\/p>

Buildings are insulated and constructed in accordance with the Energy Saving Ordinance or as a passive house during new construction or modernization. It is not uncommon for even more advanced standards to be implemented in accordance with passive house guidelines or plus house energy requirements. The Energy Saving Ordinance stipulates an insulation concept, a tightness concept and a ventilation concept.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The illustration shows a typical ventilation system. This system uses a fan to convey exhaust air from rooms such as kitchens, bathrooms and basements out of the building via a filter through the heat exchanger. After the heat exchanger, the term exhaust air is no longer used. At the same height, outside air is conveyed by a second fan via a further filter through the heat exchanger into supply air rooms such as bedrooms, children’s rooms and living rooms. From the heat exchanger onwards, this is no longer referred to as outside air but as supply air.<\/p>

The heat exchanger extracts the heat contained in the extract air (20 \u00b0C) and feeds it to the outside air (0 \u00b0C). The supply air heats up to 19 \u00b0C and the exhaust air cools down to 2 \u00b0C. This example assumes a heat supply efficiency of 90 %. The degree of heat generation depends on the outdoor temperature, indoor temperature and the air volume flow to be conveyed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
