JAUE2014-062 A Study on the Utilization of Ventilation Velocity in High-Rise Apartment Houses

Abstract

This study intends to propose a renewable energy utilization plan which installs an external air current induction duct to the exhaust duct of kitchen & bathroom and vent of the generator midst equipment shaft of a high-rise apartment house in order to improve the ventilation performance per household with the increase in exhaust wind velocity, and in the meantime, increases the exhaust wind velocity over the operational wind velocity of wind generator and may produce a certain amount of electric energy necessary for the building operations. 1) In case of utilizing the generator flue duct, the greater the inner diameter of the induction duct, the greater the exhaust wind velocity was, but in the meantime, the smaller the inner diameter of the vent, the greater the exhaust wind velocity was. Therefore, it is appropriate for the inner diameter of the induction duct to be over 50% of the inner diameter of the vent. 2) In case of utilizing exhaust duct of kitchen & bathroom, if the induction duct is not installed, it was difficult to secure the operational wind velocity for wind power generator with 60% or lower usage factor, but in the meantime, installing the induction duct led to the effect of increasing the exhaust wind velocity over the operational wind velocity of the wind power generator for all of 20~60% of usage factor.
