Air Supply Unit Compared to a Recuperator

Supply and exhaust ventilation with a recuperator combine two main functions: providing fresh air and heating it to the optimal temperature during the cold season, which saves energy.

“Why is the AIRNANNY A7
the most efficient
supply system?”.

Thanks to AIRNANNY A7’s excellent filtration
rate, you get clean and humidified indoor air.

The principle of operation is as follows:

Air inflow and outflow are carried out through ducts that are next to each other
Heat loss is noticeably reduced
The required amount of incoming fresh air is maintained
It is the recuperator that exchanges heat between gas streams with different temperatures. Such a device allows you to abandon the heater. In summer, the recuperator is able to cool the air entering the dwelling to the required temperature regime.

Pros and cons of a recuperator

Drawing a parallel between the recuperator and the breezer, it should be understood that both options provide air flow. However, recuperators also raise its temperature using waste air heat. But, the main purpose of the recuperator is not heating, but maintaining an acceptable temperature. That is why residents of warm areas can get by with an ordinary breezer. In cold areas, a device with a heating element is preferred.
The recuperator will not be able to heat the room like a breezer does. The fact is that many types of devices have temperature limitations. It will not be able to work in freezing conditions, and will simply take up space in the apartment. Breezers are more suitable to apartments, since the recuperator will not withstand the pressure of the ventilation ducts and will not be able to work at full strength.

When installing a breezers, residents will benefit from the following:

  • Fresh air and no stuffiness
  • Freedom from dust, dirt, unpleasant odors, disease-causing microorganisms in the air stream
  • If the breezer is equipped with an additional cleaning system, then even plant pollen will not enter the room. Allergy sufferers can live in peace
  • Lack of condensation on glass, dampness, and mold on the walls, which have a detrimental effect on the respiratory system
  • Automatic regulation of the system. The sensors regulate the general climate of the apartment.
    The device also has its disadvantages, such as:

  • Professionals are needed in order for it to be installed for to install it,  you need to make a rather large hole in the wall
  • Binding to a specific project of apartments. More suitable for corner layouts
  • Requires filter replacement, which is hitting your budget
  • High power consumption

AIRNANNY Breezer: clean air in apartments and houses

Many of us are used to thinking that a house is a fortress. But not in the case of gas pollution in cities, dust, and the raging coronavirus. It is a closed space that can be a breeding ground for infections that provoke allergies (pollen, mites, etc.). Indoor air is often much dirtier than the air outdoors. Regular, systematic cleaning of your surrounding is okay, but that does not solve the issue. AirNanny is an effective device that will cope with the above problems and inconveniences. It cleans and humidifies the air indoors. In this case, the air flow can be heated, and the water for humidification is disinfected by ultraviolet rays. Some models are equipped with a photocatalytic filter that decomposes all viruses, bacteria, organic compounds, industrial emissions and even odors into harmless components.

The recuperator must be cleaned of bacteria and dust

The filtration system in domestic heat exchangers depends on the condition of the filter. Typically, the package includes prefilters: coarse filters model G. Purifying the supply air, they are able to filter out large dust particles, fluffy residues, poplar fluff and even insects. However, they will not be able to retain fine dust and harmful gases.
The filters, of course, need to be cleaned. For example, models with class G filters must be cleaned at least once every three months. The cleaning steps are simple: rinse under running water or vacuum and then simply dry.
If the recuperator with filter F is processing heavily polluted air, it should be replaced at least once every 12 months, and in some cases more often. The filter elements should be inspected every 3 or 5 months.
When the supply and treated air flows in the same directions and locations, hygiene deviations can occur during the operation of the recuperator. Particles, dust and organic residues accumulate on the filter and can enter the room. Thus, the room becomes polluted through the ventilation system.
Very often, the owners of the premises do not attach importance to the timely replacement of the filter or are trying to save money. And sometimes they are even installed not for the purpose of purifying and filtering the incoming air, but striving to extend the service of the ventilation system itself. But this threatens with additional problems – this time with health.
