摘要

On trend of 'wellbeing', installation of large gas range hood has taken place in recent times in the domestic super high-rise & high-quality apartments to improve the life quality in Korea. Due to the lack of sufficient information on the performance level of these hoods, however, the construction industry is forced to rely on each supplier's simple catalogue. But most of these suppliers can not afford any independent performance testing of their own products, resulting a credibility problem. At the same time, due to the height and pressure difference between the upper-level floor and the ground level, occurrences of significant foul ordure have been reported because of the back flow of its ventilation circulation from vertical duct, resulting a lower quality of life of the tenants. So residents claim for the bad indoor quality, asserting all responsibility are belong to construction company. To solve this situation, first of all, to know and test the hoods sold in market thoroughly, especially performance, may be the first step and critical. Purpose of this research is to acquire the method to select the optimal gas range hood through the performance test under KS or prEN codes, such as performance curve, noise level, capture efficiency and power conumption and the reasonalbe grounds to adapt the optimal one to our construction fields. After research,to bestow weigh function on noise level is considered more important item than any others. Additionally, the comparison general hoods and fuctional hoods was accomplished under economical efficiency.
