Chil­dren’s edu­ca­tion­al and edu­ca­tion­al insti­tu­tions are sub­ject to spe­cial require­ments in rela­tion to air exchange and ven­ti­la­tion. It is not allowed to have stag­nant air in the premis­es — it affects the health and well-being of peo­ple (both pupils and employ­ees). It is clean, air with opti­mal tem­per­a­ture and humid­i­ty indi­ca­tors that allows you to ensure a healthy micro­cli­mate in the insti­tu­tion. This is ensured by well-orga­nized, mod­ern ven­ti­la­tion.

Why is the lack of forced ventilation dangerous in kindergartens?

Nat­ur­al air exchange in the premis­es of the kinder­garten is far from the norm. In this regard, there is a need to reg­u­lar­ly open win­dows and doors. But this, in turn, leads to heat loss, and there­fore increas­es the pay­ment for heat­ing.

Absence entails:

  • The occur­rence of dis­eases in chil­dren, the man­i­fes­ta­tion of aller­gies.
  • Spread of virus­es indoors.
  • A decrease in the lev­el of oxy­gen in the body of chil­dren, fol­lowed by a decrease in immu­ni­ty.
  • The risk of drafts due to the need for con­stant ven­ti­la­tion in the kinder­garten.
  • Poor health, lethar­gy, and hence the slow devel­op­ment of chil­dren.

If we con­sid­er the issue from the tech­ni­cal side, the devel­op­ment of projects for the orga­ni­za­tion of ven­ti­la­tion in kinder­gartens looks the same as for any oth­er struc­tures with sim­i­lar per­for­mance. But for kinder­gartens, both high-qual­i­ty aer­a­tion and the pre­ven­tion of colds are real­ly impor­tant. The lat­ter is pro­vid­ed by:

  • Cre­at­ing such a micro­cli­mate in the kinder­garten group, where the risk for the repro­duc­tion of pathogens is min­i­mized.
  • Orga­ni­za­tion of the dynam­ics of air exchange, exclud­ing drafts, hypother­mia of chil­dren.
  • Favor­able humid­i­ty and tem­per­a­ture envi­ron­ment nec­es­sary for the nor­mal func­tion­ing of the child’s immu­ni­ty.

“San­i­tary stan­dards for kinder­gartens pro­vide for an annu­al audit of the ven­ti­la­tion sys­tem. It is impor­tant to main­tain air humid­i­ty in groups with­in accept­able lim­its (from 40% to 60%), in cater­ing and laun­dry rooms up to 70% are allowed. Through ven­ti­la­tion in kinder­garten is sup­posed to be car­ried out every hour and a half for at least 10 min­utes. This should be done when the chil­dren are out for a walk — at the same time, half an hour before their arrival.

If in the warm sea­son a one-sided influx of fresh air is allowed in the pres­ence of the pupils of the gar­den, then in the cold sea­son, arti­fi­cial recu­per­a­tion of the room is sim­ply nec­es­sary. Regard­ing what tem­per­a­ture should be in kinder­garten, there are spe­cial stan­dards for dif­fer­ent cli­mat­ic regions. But +22°С in bed­rooms and no more than 24°С in play­rooms is con­sid­ered opti­mal.

Sanitary standards for kindergartens

And no mat­ter how it is spelled out in the require­ments of San­PiN, chil­dren through­out the day most­ly stay in dry rooms at air tem­per­a­tures that are far from opti­mal. And what is impor­tant here — the devel­op­ers of the ven­ti­la­tion sys­tem are not to blame for this — after all, design stan­dards in preschool insti­tu­tions are not vio­lat­ed.

It is rather dif­fi­cult to guar­an­tee the nec­es­sary air exchange due to nat­ur­al infil­tra­tion — both through and cor­ner ven­ti­la­tion types are con­nect­ed. But quite often there are vio­la­tions in the form of:

  • Non-work­ing mech­a­nisms for open­ing win­dows.
  • Seal­ing gaps in order to keep warm in win­ter and in the off-sea­son, etc.

From the above, the need for aux­il­iary forced ven­ti­la­tion clear­ly fol­lows. Dur­ing the heat­ing sea­son, the instal­la­tion of local humid­i­fiers is rel­e­vant. And at the same time, expe­ri­enced spe­cial­ists who have been work­ing on the devel­op­ment of suit­able air exchange schemes and estab­lish­ing a micro­cli­mate to achieve improved air qual­i­ty indi­ca­tors should be engaged in the design and selec­tion of a ven­ti­la­tion sys­tem for a kinder­garten.

Forced ven­ti­la­tion can look dif­fer­ent. There is:

  • sup­ply and exhaust ven­ti­la­tion with a heat exchang­er;
  • devices with sup­ply valves;
  • com­bined method.

The first works accord­ing to this prin­ci­ple: 2 air flows are formed in the premis­es, with clean and already exhaust­ed air. Com­ing from the street with­out fail pass­es fil­tra­tion, purifi­ca­tion from dirt, dust, virus­es and oth­er harm­ful microor­gan­isms. Air enters the room only after heat­ing to the opti­mum tem­per­a­ture. It is thanks to the heat exchang­er that the exhaust air mass­es share heat with fresh flows and leave the room through the air vents.

How is equipment selected?

How is equipment selected?

Before pro­ceed­ing with the devel­op­ment of the sys­tem, engi­neers care­ful­ly study the object. Which type of equip­ment will be used depends on the ini­tial con­di­tions and the num­ber of rooms. What is impor­tant when design­ing accord­ing to the norms in kinder­garten?

  1. Esti­mat­ed tem­per­a­ture in win­ter.
  2. The rate of air exchange.
  3. The vol­ume of air enter­ing and leav­ing the room.
  4. Required humid­i­ty.
  5. The cli­mat­ic zone in which the kinder­garten build­ing is locat­ed.
  6. Size of each room.

When draw­ing up the scheme, spe­cial­ists make the nec­es­sary mea­sure­ments, fol­low­ing the require­ments and san­i­tary stan­dards of the kinder­garten, for each spe­cif­ic type of room:

  • bed­rooms
  • gam­ing;
  • group rooms for chil­dren of dif­fer­ent ages;
  • dress­ing rooms;
  • toi­lets;
  • pools, etc.

School and kindergarten ventilation

“Ven­ti­la­tion of schools and kinder­gartens has noth­ing to do with asbestos-cement air ducts. The min­i­mum air expan­sion rate is 50 m³, and the max­i­mum air flow rate is 0.1 m/s. It is unac­cept­able to com­bine air ducts of dry­ers, bath­rooms, a kitchen block with oth­er rooms, and autonomous ven­ti­la­tion should be pro­vid­ed in the first-aid post, exhaust fans are also placed in the rooms.

Def­i­nite­ly, pro­fes­sion­als should deal with the selec­tion of a ven­ti­la­tion sys­tem for kinder­gartens. They will do this not only tak­ing into account san­i­tary require­ments, but also to min­i­mize ener­gy costs. Mod­ern equip­ment with recu­per­a­tion is able to per­fect­ly cope with the tasks set — to pro­vide high-qual­i­ty aer­a­tion, main­tain the desired tem­per­a­ture and humid­i­ty indi­ca­tors.

Monoblock sys­tems are capa­ble of trans­fer­ring up to 70% of heat — this is a huge plus of instal­la­tions with recu­per­a­tion. Man­u­fac­tur­ers have proven them­selves well:

After the instal­la­tion of the heat exchang­er, the spe­cial­ists instruct about the oper­a­tion and main­te­nance. Often enough to clean the chan­nels 2 to 4 times through­out the year. An excep­tion is the cater­ing depart­ment — here the require­ments are strict (as in pub­lic cater­ing points).
