Title:
AIR SUPPLY AND EXHAUST APPARATUS FOR FORCED AIR SUPPLIED AND EXHAUSTED COMBUSTION APPARATUS USING COMMON DUCT FOR MULTIPLE DWELLING HOUSES
Document Type and Number:
Japanese Patent JP3634666
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve a higher safety with a higher level of operation by modifying air supply and exhaust conditions of each floor, without handling a common duct completely to achieve a burning in a better condition with a combustion apparatus.
SOLUTION: On each floor of multiple dwelling houses, all feed air ports 8a of feed air pipes of forced air supplied and exhausted combustion apparatuses 7 are arranged to be opened into a common duct 1, and all exhaust ports 9a of exhaust pipes 9 are extended to the vicinity of an exhaust opening part 6 of the common duct 1. This keeps exhaust from being mixed completely into feed air as discharged from the combustion apparatuses on lower floors, thereby eliminating the occurrence of incomplete combustion and fading of flame, while achieving a higher level of operation and a higher safety level.
