CHECK DOOR MOUNTING STRUCTURE OF A VENTILATION SYSTEM FOR PREVENTING THE REDUCTION OF HEAT-EXCHANGE EFFICIENCY CAUSED BY WRONG COMBINATION OF A CHECK PORT BY RESTRICTING THE INTERNAL AND EXTERNAL AIR FROM BEING EXCHANGED THROUGH THE CHECK PORT

摘要

PURPOSE: A check door mounting structure of a ventilation system is provided to reduce the number of work processes for installing and separating a check door by mounting the check door by turning the check door counterclockwise and dismantling the check door by turning clockwise and pulling out the check door. CONSTITUTION: In a ventilation system having a check port(104) formed at one side of a body case to inspect the inside and replace parts and opened and closed by a check door(110), a check door mounting structure has a hanging rib(120) for installing the check door and a rib fixing tool(130) catching the hanging rib. The hanging rib and the rib fixing tool are mounted on one surface of the body case and the check door with corresponding to each other. The rib fixing tool is projected forward on a front side(50') of the body case at which the check port is installed.
