NATURAL VENTILATION SYSTEM

摘要

FIELD: ventilation for livestock buildings and other structures. SUBSTANCE: natural ventilation system of a building with roof and air exhaust well has an air plenum passage and internal air circulation passage which are separated by heat-conducting surface and by two ducts formed along ceiling and located one above other. Ducts are inclined towards walls of building and provided with condensate removing system. Air plenum passage is connected with outside atmosphere by means of air intake well located in garret, and is connected with indoor air through slots located at longitudinal walls. Second duct together with first duct ceiling and side walls of building create a clearance for circulation of indoor air. Exhaust well is connected directly with indoor air of building. Second duct is attached to ceiling by easy-to-remove hangers. EFFECT: high efficiency.
