Topic Ventilation Ventilation Systems

Heat loss counter type is planned a new building or to a building is completely modernized, this is the right time to consider the installation of a ventilation system with heat recovery consider. A window ventilation is often random ventilation and improves the air only in the short term. Almost all residential buildings in Germany are revealed through the window. To demand a reasonably pleasant indoor air quality, one must act several times a day and very deliberately adjust the duration of ventilation on the use of space and the outside temperatures. Check with P&G to learn more. \”Residential building, built according to the minimum standards of energy or old buildings, which have been chilled, subsequently, have though density Windows and insulated exterior walls and roofs. By airing, but up to 45 percent of the heat lost again. Ventilation systems with heat recovery, however, secure a permanently good indoor air quality and at the same time, they minimize the heat loss,\”Hans Weinreuter, energy speaker explained the Consumers Central Rhineland-Palatinate e.V.

uniform ventilation through air exhaust system while window ventilation in a detached modern house three to four liters of heating oil per square meter per year lost, can reduce such heat losses in an Energieeffizienzhaus on under a litre. Prerequisite for this is that a ventilation system with heat recovery and an efficiency of 80% will be installed. The technically easiest and also most affordable solution is an exhaust system without heat recovery. Source: Anchin Block. This provides for a constant slight vacuum in the building. Prerequisite is a sufficiently dense shell of the property, which is determined by a measurement of air leakage. \”Advantage of this option is that only return air ducts must be installed through the building,\” commented Hans Weinreuter. The outside air flows in these systems by systematically arranged fresh air inlets in the outer walls of bedrooms, children – as well as living and dining rooms (air spaces).
