2 . 1. 3. Hisoblash uslubi
Ishlab chiqarish binolarida uzluksiz havo almashinuvi imkoniyatini ko‘rib chiqish va xavfli ajralmalardan
himoyalash bo‘yicha muxandislik yechimlarini qo‘llash zarur. Ventilyatsiya tabiiy va mexanik turlarga bo‘linadi.
Ventilyatsion qurilmalarni ishlash effektivligini nazorat qilishda ishlab chiqarish binolarida havo almashtirish marttaligi
nazorat qilinadi, shuningdek, harorat, namlik, havo harakati tezligi o‘lchanadi va ishlab chiqarish binosining gigienik sifati
tahlil qilinadi. 1
1. Haydash zarur bo‘ladigan Q
Is.Aj , issiqlik ajralmasi quyidagi ifoda orqali aniqlanadi:
Q
Is.Aj =Q
P - Q
Ajr , kj/soat, (1.1)
bu yerda,
Q
P – ishlab chiqarish va qurilmalaridan, insonlardan issiqlik ajralishi, quyosh radiatsiyasi va boshqalar natijasida
ishlab chiqarish binosiga keladigan issiqlik miqdori, kj/soat;
Q
A jr –bino devorlari orqali atrof muhitga beriladigan issiqlik miqdori, kj/soat .
2. Issiqlik ajralganda 1 soat mobaynida ishlab chiqarish binosidan haydash zarur bo‘ladigan L havo miqdori

quyidagi ifoda orqali aniqlanadi.
L = Q
Is.Ajr  C  
np , m 2 /soat, ( 1. 2)
Bu yerda ,
C – havoning issiqlik sig‘imi, C
 1 kj/kg·K ;  – olib kiriladigan va xaydaladigan havolar haroratlarining farqi, K ;

np – olib kiriladigan havoning zichligi 
np =1.29 kg/m 3 .
3. Bino havosida zararli gazlar va changlar bo‘lganida, ularni ruhsat etiladigan normalargacha kamaytirish uchun
binoga uzatiladigan zarur havo miqdori quyidagi ifoda orqali hisoblanadi:
L=
W
cd− сn
, m 3
/soat, ( 1. 3)
bu yerda,
W - keladigan zararli ajralmalar miqdori, g/soat;
C
d - bino havosida ruhsat etiladigan zararli ajralmalar konsentratsiyasi, g/ m 3
:
- CO uchun C
d = 2·10 -2
g/ m 3
;
- Pb changi uchun C
d = 1·10 -5
g/ m 3
;
- Notoksik P changi uchun C
d = 10 -2
g/ m 3
;
C
n - ishlab chiqarish binosiga keladigan havodagi zararli aralashmalar konsentratsiyasi, g/ m 3
.
Bu topshiriqni bajarishda C
n
 0 olinadi.
4. Har bir zararli ajralma turi uchun almashtiriladigan havo mi q dori L alohida hisoblanadi. Keyin olingan
qiymatlarning eng kattasi olinadi va havo almashinuvi karrali ligi ifodasiga qo‘yiladi:
