Decentralized ventilation helps to ensure efficient air exchange in the room without the use of air ducts. Such a system is quick to install, does not disrupt existing repairs, and helps maintain a comfortable microclimate 24 hours a day.

Advantages of decentralized ventilation systems:

1. Possibility of additional energy savings

In order to maintain a comfortable indoor temperature in the summer heat or winter cold, additional energy costs are unavoidable. Due to the rise in energy prices, the demand for various energy-efficient solutions has recently increased significantly.

The goal of saving energy used for building heating is to ensure that energy resources can be used more efficiently through economically sound technical solutions that are environmentally and socially acceptable.

In Table 1 you will find a list of common solutions for saving energy used to supply heat to buildings. And also, the expected annual energy savings in case of their implementation.

As you can see, the microclimate of a room has a significant impact on the efficiency of resource use both during construction or reconstruction and during the operation of a facility. The need to lay air ducts to organize a ventilation system, organize separate technical rooms for equipment, the need to lower ceilings, and other factors force many users to decide in favor of compact decentralized ventilation systems that do not spoil the interior and existing renovations in the room.

2. Improving air quality

Today, air pollution in large cities and industrial areas, where we spend most of our time, is a major problem around the world. Construction sites, car traffic, and hazardous industrial emissions increase the level of dust, formaldehyde, benzene, and other harmful compounds in the air.

And the installation of sealed plastic windows and other ways of insulating residential premises leads to the fact that we breathe low-quality air even at home. This trend provokes an increase in the level of various diseases of the respiratory, nervous and cardiovascular systems, and contributes to the exacerbation of allergies.

Therefore, in recent years, the issue of effective ventilation has become increasingly relevant for various types of premises.

For example, medical facilities – due to the increase in the level of viral diseases, shelters – due to the prolonged stay of a large number of people, educational institutions – due to low oxygen levels and high CO2 content.

In most educational institutions in Ukraine, the ventilation system (natural or forced) does not provide an adequate level of air exchange that meets national standards. Usually, ventilation is achieved by periodically opening windows. However, in rooms such as assembly halls, classrooms, gyms, etc., this method of ventilation, especially in the cold season, is not able to provide adequate air exchange.

When people are in the room, the windows are not opened, which increases humidity, lacks oxygen, and makes the temperature uncomfortable. After all the activities are completed, ventilation usually takes place, and this leads to significant losses of heat energy. That is why it is extremely important to install a controlled mechanical ventilation system.

3.Relevance of the PRANA decentralized ventilation system

The main purpose of installing a modern decentralized ventilation system is to:

• ensuring air quality that meets national standards;
• energy saving, which is achieved through the installation of ventilation equipment using energy-saving motors;
• reduction of energy consumption for air heating due to energy recovery of exhaust air;
• efficient operation of the ventilation system through automatic control.

Decentralized ventilation systems with air recovery are a modern ventilation solution for efficient and precisely controlled air exchange in premises. It involves the installation of one or more recuperators according to the size and needs of the room.

The PRANA supply and exhaust decentralized ventilation system is one of the best modern solutions for providing fresh air to the room. The installation of the system is carried out using advanced diamond drilling technology and takes no more than two hours. This greatly facilitates the work of installers and does not compromise the integrity of the repair. The recuperator weighs from 4.5 to 22 kg (depending on the model), which reduces the load on the supporting structure of the premises. Unlike centralized air handling units, this equipment is suitable for rooms with any ceiling height.

The recuperator technology ensures simultaneous removal of «exhaust» air from the apartment and the supply of fresh air from the street.

Inside the device is a special copper heat exchanger that takes heat from the room and heats the outside air with it. As a result, the room receives already warm air flows that do not require additional heating, meaning that users do not spend extra energy and money on heating their homes.

The absence of air ducts in the ventilation system is a significant advantage in terms of energy and cost savings. Due to the free movement of air in the room, a significant reduction in energy losses and a minimum noise level are achieved.

Decentralized ventilation with heat/cold recovery is the most flexible and user-friendly system. Unlike massive centralized ventilation, this system allows you to gradually change and update ventilation equipment (if necessary, repair independent ventilation units) without interrupting operations in the room. In addition, the ability to create different microclimatic zones in one room – without erecting walls and partitions – is another significant advantage of the system.

The effectiveness of PRANA recuperators in the fight against mold and fungi at the stage of their appearance should be noted separately. This issue is extremely relevant today, as there is often an increased level of humidity in a closed room, which provokes the appearance of mold, fungus, persistent unpleasant odor, etc. Installing a recuperator helps to create a comfortable microclimate, which significantly reduces the likelihood of such unpleasant phenomena.

PRANA’s team of professionals is always ready to advise each client when choosing a recuperator and provide information on the specifics of operation. Therefore, to ensure maximum ventilation efficiency, we advise you to listen to the advice of professionals and contact trusted installers before purchasing it.
