Recuperation is also known as mechanical ventilation with heat recovery. First of all, it is a way to save money on home heating. Moreover, it is a way to increase the comfort of household members and take care of their health. What other advantages does recuperation have?
What are the benefits of recuperation?
An important function recuperation is air purification. This way you can get rid of pollutants and allergens. The filters used in the installation will keep outside air polluted as a result of burning e.g. coal in nearby buildings.
In addition, the benefits of recuperation include:
- Energy saving
- air purification from dust mites, viruses, bacteria, pollen harmful to allergy sufferers and fumes from cars and chimneys
- controlling the amount of extracted and supplied air
- possibility of quick "ventilation" of rooms
- removing moisture from rooms
- clean air without having to open the window (this also reduces noise if you live next to a busy road).
It is also worth noting that in rooms with mechanical ventilation, laundry and floors dry faster after washing. The ease of using heat recovery will be enhanced by connecting the system to the intelligent building installation. You can also choose, for example, recuperators with WiFi control (bought e.g. from the Onninen hydraulic wholesaler , where you will also find, among others, ventilation units, EasyFlow ducts, angular or straight manifold, pipes, distribution and plenum boxes, insulated and ventilation duct, plate assembly and connection).

How does mechanical ventilation work?
The operation of mechanical ventilation is based on air movement generated by a special device - a recuperator. It allows you to control the movement of exhaust and supply air and to recover heat from the already used "dirty" air, which is humid and saturated with carbon dioxide. Simply put, heat recovery is an air exchange system in the house, which involves removing stale air and introducing clean air, while recovering part of the heat already accumulated.
The heart of the entire installation is the recuperator - it is a heat recovery center with an exchanger used for heat recovery. The extracted air flows simultaneously in two directions:
- clean and cold air is drawn from outside the building
- stale and warm air is extracted outside through anemostats.
Anemostats are round grilles placed as part of the operation of this installation on the walls or ceiling, through which air is transported. Both of these directions and streams meet in the recuperator, i.e. the heat exchanger, but each of them flows through a separate channel. Dirty air leaves its heat here, and cold air takes it over and goes into the ventilation duct. Then the air goes to all rooms and is distributed throughout the house, and the used air goes outside.
The mentioned recuperator has four connection stubs to which the ventilation ducts are connected:
- intake - brings cold air from outside
- launcher - discharges air to the outside
- air supply to rooms - supplies warm and filtered air to rooms
- extractor from rooms - transports air from rooms to the recuperator.
Channel 1 draws in cold air and introduces it to the exchanger in the recuperator. At the same time, channel 4 draws in warm exhaust air and also introduces it to the exchanger. Energy is transferred here (heat exchange) - the air from the 4th channel heats it in the 1st channel. Then, warm and fresh air is blown into the room through the 3rd channel, and at the same time, the 2nd channel throws out the polluted and temperature-free air. .
Vertical and horizontal channels in heat recovery
Ventilation is most often associated with the use of vertical air supply and exhaust channels. And in reality this is most often the case. However, it is also possible to run the channels horizontally. However, you should be aware that this may mean worse efficiency of the ventilation system, but it does not have to be so. It is worth consulting this issue with experienced specialists in this field. All necessary ventilation elements can be purchased at the Onninen wholesaler, where you will find, among others: fans, air curtains, heaters, and ventilation ducts and fittings.
