- About Lunos DCV
Needs-driven regulation of the Silvento exhaust air fans has been fitted with a humidity-temperature sensor. This innovative regulation adjusts the fan speed 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 in 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 mould 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.
2. Systems with Heat Recovery All living room areas are equipped with heat recovery units in this extremely efficient system. The new ego also enables ventilation of classical exhaust air rooms using this device. Living room areas are equipped with the well-proven e2. This system can save €6-10,000 when compared to centralised systems.
- The e² and ego principle in ventilation systems with heat recovery
- Ventilation in living rooms is applied as in bedrooms, with e²:
- Ventilation in the bathroom, WC and kitchen with ego:
The ego also operates in accordance with the principle of the regenerative heat exchanger. A storage element charges with heat as in the well-known e2. However, this is distributed skilfully with two fans so that supply and exhaust air are provided simultaneously. A second device is not required for operation. The system can also be switched to exhaust air mode in which a very high flow of 45 m3/h is discharged in order to enable fresh air to flow into the room quickly (e.g. WC or bathroom).
3. Hybrid Systems Hybrid ventilation systems are combinations of at least two different types of ventilation. Combination of exhaust air devices and fans with heat recovery are especially effective. The benefits of such hybrid combinations are clear: while living areas are equipped with heat recovery devices, the more favourably priced exhaust air device can be used in classical exhaust air rooms such as the bathroom, WC or kitchen which are only used when required.
- Combining with different Systems
- The e² Principle
- The exhaust air fans of the 160 series
With its new products AB/30 and RA 15-60, LUNOS provides an ideal enhancement to the 160 series in classical exhaust air rooms subjected to humidity, such as the bathroom, WC and the kitchen. With the aesthetic dreams of house and apartment owners in mind, engineers at LUNOS also focused on the design when developing the new fans. These fans present themselves like their ‘big brother’ e2: inside panel, filter and outside grille are from the same product family, whereby the RA 15-60 is more pressure-resistant than its alternative, the AB 30/60.
