SYSTEM OF VENTILATION PASSAGES FOR REPLACEMENT OF AT LEAST SOME PART OF AIR IN SECTION OF CUBICLES OR IN SYSTEM OF CUBICLES WITH SECTIONS OF CUBICLES, AND VENTILATION METHOD OF SECTIONS OF CUBICLES OR SYSTEM OF CUBICLES Russian patent published in 2014 - IPC A01K1/00 F24F7/00 

FIELD: heating, ventilation.

SUBSTANCE: group of inventions relates to a method for replacement of at least some part of air at least in some part of a building containing an inside room and a floor. The method involves supply of the first air volume from the first station to the inside room of the building or to space interconnected through the first air duct, and/or removal of the second air volume from the room of the building or from the space to the second station through the second air duct. Cross-section of the first air duct is reduced in the direction from the first end of the first air duct to the second end of the first air duct, and/or cross-section of the second air duct is reduced in the direction from the first end of the second air duct to the second end of the second air duct. A system of cubicles includes at least two sections of cubicles. A system of ventilation passages includes the first air duct, the second air duct, the first suction, pumping or blowing device and the second suction, pumping or blowing device. The first end of the first air duct faces to the second end of the second air duct or to the first end of the second air duct. The first and the second air ducts are located at some distance from each other or have a common wall. The system can be used for optimisation of total animal transportation distance so that the shortest possible distance of transportation is provided.

EFFECT: providing ventilation of rooms due to ventilation units having favourable effect both on an animal and a human being.
