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 QIs.Aj, issiqlik ajralmasi quyidagi ifoda orqali aniqlanadi:
QIs.Aj =QP - QAjr, kj/soat, (1.1)
bu yerda,
QP – ishlab chiqarish va qurilmalaridan, insonlardan issiqlik ajralishi, quyosh radiatsiyasi va boshqalar natijasida ishlab chiqarish binosiga keladigan issiqlik miqdori, kj/soat;
QAjr –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 = QIs.Ajr C np, m /soat, (1.2)
Bu yerda,
C – havoning issiqlik sig‘imi, C1 kj/kg·K; – olib kiriladigan va xaydaladigan havolar haroratlarining farqi, K; np – olib kiriladigan havoning zichligi np =1.29 kg/m .
3. Bino havosida zararli gazlar va changlar bo‘lganida, ularni ruhsat etiladigan normalargacha kamaytirish uchun binoga uzatiladigan zarur havo miqdori quyidagi ifoda orqali hisoblanadi:
, m3/soat, (1.3)
bu yerda,
W - keladigan zararli ajralmalar miqdori, g/soat;
Cd - bino havosida ruhsat etiladigan zararli ajralmalar konsentratsiyasi, g/ m3:
- CO uchun Cd= 2·10-2 g/ m3;
- Pb changi uchun Cd= 1·10-5 g/ m3;
- Notoksik P changi uchun Cd= 10-2 g/ m3;
Cn - ishlab chiqarish binosiga keladigan havodagi zararli aralashmalar konsentratsiyasi, g/ m3.
Bu topshiriqni bajarishda Cn0 olinadi.
4. Har bir zararli ajralma turi uchun almashtiriladigan havo miqdori L alohida hisoblanadi. Keyin olingan qiymatlarning eng kattasi olinadi va havo almashinuvi karraliligi ifodasiga qo‘yiladi:
, 1/soat. (1.4)
