Centralized ventilation with recuperation
A profitable investment in further comfortable living in the house will be the use of air-handling unit with heat recovery. Ventilation of an aerated concrete house thanks to such equipment is carried out throughout the house thanks to air ducts through which air moves. Therefore, such a system is called centralized. The air handling unit consists of one casing, which contains all the necessary components – fans, heat exchanger, heater, and filters for air purification. In this design, the equipment is easy to manage and there will be no difficulties in operation.
The heat recuperator in the unit unloads the heating system, taking heat from the exhaust air and transferring it to the supply air, thereby heating it. The availability of such an element in the air-handling unit allows you to save on energy resources during the cold period of time, especially taking into consideration ever-increasing tariffs.
To organize a centralized ventilation system, you can use air handling units of well-known brands:
Today, one of the most popular and requested models of centralized ventilation units is the Jablotron Futura L/M. It is perfect for supplying fresh air and extracting exhaust air in both houses and apartments. This unique equipment combines simplicity and sophistication in design, as well as high efficiency, energy efficiency, multi-level air purification and convenient remote control.
It is also important to note the availability of an enthalpy heat exchanger that reuses heat, as well as excess humidity in the premises, for its recycling.
Thanks to a system of VAV-клапанов the equipment can supply air separately to each room in case the level of carbon dioxide in a particular room has exceeded the norm. This function can not only provide more efficient air distribution, but also significantly save on resources. Accordingly, every resident will be able to feel comfortable, regardless of whether he is in the bedroom or living room.
Let's get acquainted with our project based on ventilation equipped with VAV-valves.
Moreover, when organizing ventilation in the kitchen, it is recommended to use a Faber kitchen hood together with a Jablotron ventilation unit equipped with VAV valves. In this case, when the kitchen hood in the kitchen is turned on, the ventilation system begins to intensively remove air in the cooking zone (the volume of intake air is preliminarily calculated by engineers and adjusted separately to the valve.) At the same time, in other “dirty areas” – a bathroom, a wardrobe, the VAV valves close automatically.
The main task and advantage of such a system is to ensure the balance of supply and exhaust air.
When the kitchen hood is activated in the kitchen, the volume of removed air may exceed the amount of supplied air. In this case, the ventilation unit increases its performance in order to compensate for the removed volume with supply air.
Another significant advantage of such a system is the preservation of the heat of the exhaust air. Because the Faber hood is connected to the general ventilation system, it does not just “throw out” the heat received from the frying surface along with the exhaust air, but, if necessary, reuse it thanks to the heat recovery.
It is important to note that Faber equipment has a filtration system that prevents grease and other contaminants from entering the heat exchanger.
Thus, effective ventilation in the house is ensured, the smells of cooking do not spread to other rooms, and the load on the heating system during the cold season is also reduced.
The units can be combined with smart home systems via ModBus, in this case you don’t even need to monitor the operation of the system because it will follow and adapt itself to the already programmed work scenarios.
