D-58 Study on the design method of higher reliability for residential ventilation system with ducts : Part 3 Investigation on calculation protocol for air flow rate of ventilation systems with multiple terminals

Abstract

A measuring method of static pressure losses on components of ventilation systems employing ducts has been investigated. Data of P-Q(pressure loss-air flow rate) characteristic of components of ventilation systems, such as fans, flexible ducts, and multiple terminals, were measured by utilizing this method. These measuring data were investigation for the purpose of developing a calculation or designing protocol of pressure losses of ventilation systems.
