A discharge coefficient equation was incorporated into a mass balancing procedure to compute the elevation of the neutral pressure axis (NPA) for a general distribution of openings. An equation was developed to compute the discharge coefficient of an arbitrary opening as a function of the three dimensional geometry, the pressure difference, the total minor loss coefficient, and the air properties.
This paper outlines the development of guidelines for the design and installation of ventilation systems installed in energy efficient homes constructed under the R-2000 Home Program of Energy, Mines and Resources Canada. The guidelines represent one of the first initiatives to develop comprehensive requirements for the design and installation of mechanical ventilation systems for residential buildings in Canada. The guidelines outline requirements for a continuous supply of ventilation air to dilute and therefore control contaminants produced from dispersed sources in a home (e.g.
