We undertake the installation of ventilation systems of industrial institutions, hotels, cultural and social institutions. We place special emphasis on the design and implementation of heat recovery ventilation.
WHY IS HEAT RECOVERY VENTILATION GOOD?
Indoor air quality
The primary purpose of the ventilation system is to ensure good indoor air quality by replacing used air with fresh air coming from outside. While indoor air pollution from human exhalation, indoor activities, emissions from building materials and furniture are a combination of several types of pollutants, excessive humidity does not only reduce comfort level but also plays a significant role in deteriorating the condition of the building. Selecting and installing the appropriate ventilation system is the best way to maintain good indoor air quality.
Better air exchange, more comfort
The ventilation system contributes greatly to improving indoor air quality by ventilating according to our needs. While people located in a room, the relative humidity increases, then the shutters of the diffusers with vapor sensors open, the air flow increases. Activities in the service rooms (kitchen, bathroom, toilet) are associated with increased odor and vapor emissions. As a result, the exhaust diffusers open due to the vapor or motion sensors, thereby increasing the amount of exhaust air and accelerating the removal of the contaminated air.
Heat recovery ventilation to meet new requirements for energy efficiency in buildings
Due to the new requirements for energy efficiency and noise reduction in apartments, the newly built and renovated buildings form a kind of an enclosed husk because of the increased heat, sound and air isolation, while the old buildings are usually “over-ventilated” due to heat losses along windows and exterior walls. In new and renovated buildings, fresh air can not enter if ventilation is lacking or inappropriate, and this causes obvious problems: air quality and comfort clearly deteriorate and vapor can condense on the coldest surfaces of the apartment. Therefore in some places, in the comfort rooms, air inlets must be created, on which controlled ventilation elements must be installed so the fresh air can enter the apartment at all. To eliminate the problems, a new ventilation system must be created, so the fresh air can enter the comfort rooms, and the humid, polluted air can leave service rooms. At the same time excessive ventilation must be avoided because high air exchange also has a drawback: the removal of warm air contributes to energy loss. However, the energy use of buildings falls under increasingly strict regulations. Consequently, the energy efficiency of the ventilation system is already a real challenge for the homes of the present and the future.
Ventilation and energy saving
Nowadays ventilation is the cornerstone of energy saving. While in an uninsulated or a poorly insulated apartment the energy saving due to ventilations is an average 20-25 % of the heating costs, in a very good airtight house the saving can be as high as 50 % of the heat loss.
Our heat recovery ventilation solutions are continuously regulating the amount of supply and exhaust air by sensing air quality of rooms in the building. Therefore the optimal air exchange of the building is solved, it will not be under or over ventilated.
