Fresh air at home is not only about health and a refreshing atmosphere. It also means more energy for life! Heat recovery systems will conveniently ensure that you always feel a refreshing and atmospheric aura in your home. We have prepared some tips that will help you learn what air handling units are and how to choose a device that suits your needs.

Many of us like to ventilate overheated rooms in winter and feel a comfortable breeze of coolness in hot summer. At the same time, no one likes to let polluted air into the house in winter and insects in summer.
On the other hand, specialists emphasize how important continuous air circulation is. Thanks to the supply of fresh air, we simply get sick less often. Unfortunately, in many buildings traditional ventilation systems do not function efficiently.

A solid ventilation unit turns out to be an excellent solution. Such a device not only ensures good air exchange, but also recovers heat. The air handling unit is a modern way to constantly supply fresh air to the interior of the building. Additionally, heat recovery increases the comfort of people staying in closed rooms, while taking care of their health by preventing the formation of fungi and mold.

How does an air handling unit work?

In order to describe the principle of operation of an air handling unit as simply and vividly as possible, it is worth noting that in winter, when we ventilate rooms, we let out warm, heated air and let in fresh, cold air that we only need to heat. Heat recovery gives us greater control over the ventilation system in the building, and thanks to these devices it is more energy-saving and efficient. The air handling unit allows you to heat the air supplied to the rooms without using additional energy.energii. The principle of its operation is to recover heat from ventilation, which means that it heats the air flowing into the house with the heat of the exhaust air.

Why is it worth investing in ventilation with heat recovery?

Before purchasing an air handling unit, you should decide whether you want to install a full installation or use a decentralized system. In the first case, the system will be the most efficient and best suited, while individual devices, such as a wall heat recovery unit, will only be used to ventilate the room in which they are installed. It is also worth paying attention to the enthalpy recuperator, which, in addition to heat recovery, also provides users with moisture recovery.

When choosing an air handling unit, remember both the type of device and its power adapted to the building’s area and the number of people who will stay in the rooms. It may happen that poorly selected heat recovery will not fulfill its function, which in turn will make the rooms stuffy. When choosing an air handling unit, it is worth paying attention to its efficiency and classification according to energy classes. The range of classes is large, from A+ to G. Significant differences between AHUs include how much noise they emit, i.e. annoying noise during operation.

When purchasing an air handling unit, you should also pay attention to the exchanger and heat recovery, and whether the air flow is automatically balanced. On a less technical note, it is also important whether the filters used in the device are easily available from the manufacturer and whether their replacement requires the help of a specialist. If you want to be sure that the device will be well selected and that replacement parts are always available, it is worth considering DEFRO heat recovery units.
