Basics of Home ventilation

The Principle of Home Ventilation

LUNOS ventilation systems are based on airflow through the entire living areas in accordance with specific requirements. For efficient ventilation, the decentralised fans can be combined into three different ventilation systems:

Exhaust air system

In accordance with the requirements and the level of humidity, fans discharge the exhaust air from the bathroom, kitchen, toilet or washroom into the open or into exhaust air shafts. These fans run permanently, thereby creating negative pressure. As a result of this negative pressure, fresh, filtered air flows through the outer wall air vents into the living room and bedroom, children's rooms and work rooms. Particular attention is paid to humidity-regulated home ventilation. By means of this ventilation system, significant losses of ventilation heat can be saved in accordance with EnEV.

Exhaust air system

Hybrid system

Hybrid ventilation systems are combinations of at least two different types of ventilation. Combinations of exhaust devices and ventilators with heat recovery are especially effective. The benefits of such hybrid combinations are obvious: while the living rooms are equipped with heat recovery devices, a low-cost air device, which is operated only when necessary, can be used in classical exhaust air rooms. In bathrooms and toilets without window, this is even required pursuant to DIN 18017-3.

Hybrid system

System with heat recovery

In this highly efficient system, all rooms of the apartment are equipped with heat recovery devices. With the ventilation units of LUNOS it is possible to operate ventilation and exhaust air systems with heat recovery via the outer wall even in classical exhaust air rooms.

Via the ego, the e² can be used to optimum effect in a ventilation system with heat recovery. On account of the decentralized concept, the individual fans can be installed exactly where they are required.

e² fans are used in living room areas, and two units are always in operation as pairs. Therefore, an even number of units must always be installed to ensure the units work properly.

Functional rooms such as bathrooms and kitchens are ventilated via the ego. Operation in pairs is not required, since two ‘small’ e² in the ego ensures supply and exhaust air with heat recovery.
