Exhaust air system
According to the needs and the degree of humidity, fans transport air from the bathroom, kitchen, or laundry room to the outside or in air ducts. This will create in the living area a slight vacuum. Because of this under pressure flows fresh and filtered air through supply air elements in the living room, bedroom, children's room and study rooms. Special attention is given to the humidity-controlled ventilation systems. These officially approved systems can reduce the loss of heat energy in accordance with the energy-saving considerable extent.
Innovative Control: Humidity and Temperature
Needs-driven regulation of the Silvento exhaust air fans has been fitted with a humidity-/temperature sensor. This innovative regulation adjusts the fan stage automatically to the ventilation requirements: the air flow increases or decreases depending on the relative humidity. This ensures that as much ventilation is made as required and as little as possible.
The sensor integrated into the suction section of the exhaust air fan records the temperature as well as the humidity content of the exhaust air flow. Since the fan is installed in the bathroom or WC where different room air conditions arise compared to the living room areas, the simultaneous evaluation of temperature and humidity ensures ventilation (step 1 to 4) adjusted to the room air conditions in the living room areas.
Therefore, this control not only considers the requirements in the bathroom but also the needs in the living room area and provides effective protection against moisture damage and mold formation. The automatic seasonal time switch adjusts the fan automatically to the lowest stage in summer and back to humidity control in the transition period and winter season.
Financial Support for LUNOS exhaust air systems
The remarkable energy saving effects of a building by using home ventilation have been confirmed by the Federal Industrial Association of Germany for House, Energy and Environmental Technology and by the Fraunhofer Institute for Building Physics. As a result, the energy saving features of regulated home ventilation are being rewarded by the legislator in the form of a financial subsidy. In addition to the energetic benefits, the building owner can also benefit from a range of other plus points: a healthy, cosy indoor climate which is always full of fresh air, and protection of the building substance, which increases the value of the property.
