DRAFT CHAMBER AIR FEED/EXHAUST SYSTEM

摘要

PROBLEM TO BE SOLVED: To constitute the above system in such a manner that the balance of a the air-intake and air volume displacement can be obtained regardless of the air-intake and air volume displacement of an air conditioner for indoor use when a plurality of draft chambers are installed in one chamber. SOLUTION: The exhaust air quantity from the respective chamber bodies 1, a plurality of which are arranged in one chamber are exhaust outside by one system of exhaust wind trunk (37) and the air-intake volume from outside is blown off from diffusers 43 into the room 3 by one system of air-intake wind trunk 49. The respective chamber bodies 1 are provided with opening/ closing control valves 31 for exhaust and opening/closing control valves 39 for air intake of which the valve opening degrees move to an open or close side in correspondence to the opening or closing of opening/closing doors 15. The quantity of the air intake appropriate for the air volume displacement is taken into the respective chamber bodies by the opening/closing control valves 31 for exhaust and the opening/closing control valves 39 for air intake are in correspondence to the opening and closing rates of the opening/closing doors 15, by which the respectively independently balanced air-intake and air volume displacement are obtained.
