Abstract

As a result of developing and evaluation the performance of the kitchen ventilation system, a new kitchen ventilation system, which can improve the exhaust performance of the kitchen ventilation system installed in the existing apartment house and improve the noise problem from the range hood, was conducted as follows. The same conclusion was reached. First, the development system is a kitchen exhaust system, and consists of a roof fan with a power fan, an exhaust standing duct, and a range hood that can selectively incorporate a power fan. It was possible to improve the exhaust performance through the control of the roof fan with a built-in PCB, and the noise level in the kitchen could be reduced below the standard valueby removing the power fan in the range hood. Second, the noise level generated by the range hood could be reduced to below the standard value by removing the power fan. The noise level of the range hood measured under various assumed conditions met the standards of the Korean Standard for Equipment Association. As a result of verifying the performance of the kitchen exhaust performance, noise in the range hood, dew condensation, and backflow into the household, which have been pointed out as problems in the existing kitchen ventilation system. It shows that natural ventilation performance, convenience of use, maintenance and energy cost are reduced through the electric air damper.
