A Study on the Vertical Sectional Exhaust Characteristics from Kitchens Using a Vertical Shaft
Abstract
Recently a high-rise building is built in many places. However some problems are occurred in the high-risebuildings. Especially, at the case of the kitchen exhaust using vertical shaft, the kitchen exhaust fansometimes can not work normally because of unbalance of pressure inside the shaft. In this study, under theassumption that the kitchen exhaust system applied uniformly can not cope with the various changes of theoutside environment, the vertical sectional characteristics of a kitchen exhaust using vertial shaft is analyzed.Outside temperature, number of the floors and operating ratio of the vertically connected fan are selectedas major parameter. And it is analyzed by a network simulation method. In case of 60 stories building, thestandard deviations are 115.6 at the second floor, 74.9 at the 30th floor and 20.7 at the 60th floor. Thestandard deviation at the lower part is about 5.5 times than the upper part. So the results of the simulationshow that the kitchen exhaust system should be installed considering the vertical sectional exhaustcharacteristics.
