One problem on the 24 hours house ventilation system is trouble with maintenance of dirt air filter. The axial flow cyclone air intake hood was developed in order to reduce filter maintenance cost. However, the optimum design parameters of this cyclone intake hood have not been obtained yet, especially the relationship between performance for a cyclone dust collector and internal flow in an intake hood are unknown. The purpose of this investigation is to make clear the relationship between performance and internal flow. As the result of this study, velocity and pressure distributions in intake hood were shown, and we examined the relationship between performance for a cyclone dust collector and these results.
