The features of air systems for preschool institutions hold great importance for children. Ventilation issues in educational institutions are crucial for maintaining the well-being of children. Calculating the ventilation of a kindergarten and ensuring clean air in the building allows you to keep the children's well-being at the correct level. If clean air is provided by natural ventilation and forced ventilation through fans, it must be properly designed.
Ventilation requirements in kindergartens and nurseries are specifically designed as essential initial data for calculating the ventilation system. Accordingly, ERF GROUP possesses extensive knowledge and experience in both ventilation systems and regulations.
For almost every room where children spend time, requirements for temperature regime and supply and exhaust air changes are specified. All recommendations and regulations include the obligation to regularly ventilate the environment when children are not present. The recommended methods are draft and corner ventilation.
The duration of air cooling may vary, generally depending on the strength and direction of the wind, the outside air temperature, and the operating mode of the heating system. It is necessary to ventilate the room with an air flow for at least 10 minutes every 1.5 hours. During ventilation, the maximum allowable temperature drop is 4 degrees.
When it is hot outside, windows on only one side of the room may be opened in the presence of children. Ventilation from toilets is strictly prohibited. Overall, ERF GROUP offers a wide and comprehensive range of products and services.
Generally, air exchange is extremely important for the development and health of children. At this point, the sleeping area should be ventilated before putting the children to bed. When it is cold outside, windows should be closed 10 minutes before the children arrive. After the children fall asleep, windows can be opened, but only on one side.
They should be closed half an hour before the children wake up. In warm seasons, sleep should occur with the windows open, but drafts should not be allowed. ERF GROUP's ventilation systems are an effective way of natural ventilation.
All product features are also widely used in forced supply and exhaust ventilation in preschool institution buildings. The setup in kindergartens also has its own unique features.
Features of ventilation regulations in kindergartens:
In two-story buildings, natural induction exhaust channels are used to regulate ventilation for fresh air. In service rooms or kitchens, the air exchange rate is increased to 3-5 times per hour, and in toilets, it is increased to 2-5 times per hour, requiring equipment in stimulating ventilation channels.
In ERF GROUP system installations, technical features and setups provide recommended ground-level or corner ventilation for group dining and play areas, as well as for bedrooms, kitchens, utility rooms, and toilet/bathrooms located in the IV climate zone.
In children's rooms, at least 50% of the windows have transom windows. The area of the transom openings is about 1/40 to 1/50 of the floor area. The outer sash of the transom windows opens from bottom to top, and the windows have lever devices and side curtains.
In the main rooms of the children's institution groups, the system installation ensures a constant air temperature of 20°C with 60-70% relative humidity. A wall thermometer is hung at a height of 1 meter from the floor in group rooms.
There are two options for kindergarten ventilation systems: traditional and modern. The traditional (simple) version of kindergarten ventilation used to rely on natural ventilation.
Air was provided through ventilation holes and natural leaks in the windows, and the exhaust went from the well to the roof through natural air pressure. In other words, hot air would rise. Of course, such a ventilation system has more disadvantages than advantages.
In ERF GROUP system installations, corner and internal ventilation are provided in areas where children spend the most time (bedrooms, playrooms).
If the kindergarten is located in a place where the temperature remains above +30°C for a long time during the hot season, the most suitable service is provided by ensuring cross or corner ventilation in rooms, drying rooms, toilets, and kitchens.
When a room is ventilated in this way, for example, when ventilating a playroom, air exits from the bedroom or dressing room, and when ventilating from the kitchen, air is expelled from adjacent rooms through the pantry. This type of ventilation will not be necessary in extreme northern conditions.
The features of ventilation in kindergartens involve the operating principle of the supply and exhaust ventilation system. In rooms, two air streams are created, clean and dirty, thanks to the supply and exhaust units. Street air masses passing through the filter are purified from dust, dirt, and microorganisms, then heated to the required temperature before entering the room.
With the help of fans, the dirty air stream enters the unit's air ducts and is expelled outside the facility. In this regard, ERF GROUP services require the installation of a ventilation system to minimize energy costs. ERF GROUP prefers modern installations because they are economical and can provide the necessary levels of heating and air humidification.
A supply and exhaust system with a heat exchanger is ideal for this role. It significantly reduces the cost of heating supply air during the winter season while ensuring a continuous supply of fresh air at the set temperature.
The recuperator transfers the heat from the exhaust air to the supply air masses, thus consuming much less electricity. At the same time, it will be cleaner and healthier from certain points.
Kindergartens with crowded groups of children and insufficient ventilation contain large amounts of carbon dioxide in the air. This can cause symptoms in children and caregivers, such as migraines and a constant feeling of nausea. However, proper ventilation in kindergartens ensures sufficient oxygen content in the air masses, reduces the number of harmful substances in the air masses, eliminates certain odors that negatively affect the nerves of different age groups, normalizes the humidity of the air masses, and reduces the spread of various pests and fungal spores.
At this point, ERF GROUP products are of great importance. They establish highly successful systems both in areas without ventilation and in areas where children spend the most time.
ERF GROUP adheres to the basic rules for ventilation in preschool institutions. It takes all necessary measures to prevent excessive amounts of carbon dioxide, which can harm all child groups, in the air of a preschool institution.
ERF GROUP has also developed a special program for implementing ventilation in preschool institutions. This results in highly advanced designs and technical systems that comply with all regulations.
