CO2

Did you know that…

• Carbon dioxide (chemical formula CO2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms.
• The carbon dioxide sensor measures pressure, temperature, humidity and CO2 and adjusts them if necessary. If there are a lot of people in the room, the air can become thick, which can cause a feeling of nausea and fatigue. In this case, the automatic ventilation system will operate in accordance with the principle of energy efficiency. If there is nobody in the room then the carbon dioxide content in the air drops and the systems turn themselves to the lowest level to save energy again.
• In the absence of air exchange, indoor air contaminates quite quickly. The main air pollutant is the person himself or some of the household devices used. When inhaled, oxygen is used in the air and carbon dioxide is exhaled, and if its concentration rises above normal, human work capacity and efficieny will be reduced.
• Thermal-proof ventilation simultaneously performs several functions: it provides clean air in the rooms, reduces heating bills and saves the environment.The system is easy to operate: the heat from the outgoing air is taken and the incoming air is heated up.
• Rakvere Kindergarten building is being taken by the air 12 “Salda” small ventilation units and 4 “Remak” devices.
• All data can be conveniently monitored, controlled, and adjusted as required by Fidelix operating system, which brings together all of the house's technical systems. Recorded data provides a good opportunity to analyze whether and to what extent the equipment used in the house has been effective, which has been energy-saving, and certainly the main thing to be aware of is the well-being and health of children and teachers in kindergartens.

What is the benefit of forced ventilation with heat recovery?

• -Fresh air
• -Warmth at home / kindergarten
• -Financial savings on heating bills
• -Removement of moisture from buildings and indoor rooms
• -Health-friendly indoor climate
• -It maintains up to 95% of the thermal energy.
