Second, the specification on the basis of 2 "Ventilation and Air Conditioning Engineering Construction Quality Acceptance quality GB50243-2002" provisions of the damper settings are as follows: 6.2.5 fire dampers, exhaust valve (port) Installation direction, location should be correct. Fire dampers on both sides of the partition wall, from the wall surface should not exceed 200mm. Third, considering 1, fire dampers of "fire zone setting position" and "distance of 200mm from the wall" requirement MEE damper, aware of the mounting position of the damper is determined; (2) air conditioning room space determines whether muffler can be installed in the air conditioning room, of course, from the muffler noise perspective, the muffler placed in the air-conditioned room is ideal.
