Ventilation has several tasks in the conservatory and on glass façades. On the one hand, it is used in the automatic conservatory climate control to regulate the room temperature and humidity. Another objective is good air quality. CO2 and germ contamination are reduced by regular air exchange. The air is "fresh". If you want to be sure of this, install a carbon dioxide sensor in addition to the thermo/hygrometer, which is included in the scope of delivery of conservatory control systems such as the WS1000 Connect from Elsner Elektronik. The combined sensor with temperature, humidity and CO2 measurement replaces the standard sensor. In this way, additional automatic ventilation is provided if the CO2 level is too high.
In winter gardens, condensation on the panes is an issue that can also be avoided with proper ventilation. Air circulation transports the moisture away from the pane and creates a clear view. In addition, circulation improves heat distribution in the room. Especially in conservatories that extend over two storeys, it is otherwise warmer upstairs than downstairs. In the cold season, the heat from the ridge area is valuable and should not be dissipated but distributed in the room.
While air exchange can be achieved naturally via windows, circulation is one of the advantages of blower fans. There are models, such as the WL400 and WL800 from Elsner Elektronik, which have an exhaust air mode and a recirculation mode. The fans are installed in the conservatory roof like a pane of glass and with their restrained design, colours that can be ordered individually and a very low noise level, are made for living spaces.
Further plus points of motorised ventilation result from the fact that, unlike skylights and windows, there are no unprotected openings. The ventilation units do their job even in rain and strong winds. And, unlike windows, they are not a potential entry point for thieves. Insect or pollen screens on the supply air unit help against smaller "intruders".
By blowing the air out with the exhaust air unit, the air exchange is ensured, regardless of the thermal conditions in the room or air movement outside. While the exhaust air is being blown out, fresh air flows in automatically at the supply air unit. Ventilation units are a safe alternative or a helpful supplement for a good climate in the winter garden.
