- Abstract
- Natural ventilation has the potential to reduce energy consumption and operating costs compared with mechanical ventilation. A pressure coefficient(Cp) is a dimensionless number which describes the relative pressures throughout a flow field and it is used for calculating airflow rates. However, fluctuation of wind velocity is very large and the velocity is below 2.5㎧. Purpose of this study is to analyze the characteristics of pressure coefficient distribution in low wind velocity below 2.5㎧ through long term measurement. In above 4㎧, △Cp values are similar with AIVC Database. However, In low wind velocity, there are much difference in △Cp between measurement and database and fluctuation of △Cp is very large.
