Tashmatov	FEATURES OF AIR EXCHANGE SOLUTIONS IN HIGH-RISE RESIDENTIAL BUILDINGS	2025	6	.pdf	application/pdf	2350	154	58	The selection of supply and exhaust ventilation fans is made based on pressures depending on the height of the building: at 20 floors not less than 20 mm H2O, at 30 floors not less than 30 mm H2O, etc. The initial value for determining the cross-section of the supply and exhaust ventilation ducts in high-rise buildings should be considered the air velocity, which is taken in such a way that in the event of fan inactivity, the system can operate on natural induction.	cache/ajtas-3063.pdf	txt/ajtas-3063.txt
