How to choose the right ceiling diffuser
According to different types of diffusers, there are rectangular diffusers, circular multi-layer cone diffusers, circular convex diffusers, the airflow pattern for the flat send adherence type; (2) self-operated temperature-controlled variable flow type diffusers , send back (suction) dual-use diffusers.
Selection of the material of the diffuser are mainly plastic, steel and aluminum alloy two categories.
Overview
(1) According to the characteristics of the project, the type of airflow organization required. Regulating performance and air supply mode, etc., select the appropriate type of air vent.
(2) According to the required air volume [air supply or exhaust (return) wind], in the neck of the air outlet (or air outlet inlet and outlet section) within the range of permissible wind speed, to determine the size of the required air outlet. If the wind speed (generally 2 ~ 5m / s) to determine the size of the air outlet, should take into account the effective area of the air outlet rate (generally 30% ~ 60%).
(3) check the main technical performance of the selected air vent. Such as range, pressure loss, noise indicators and the working area of the wind speed and temperature difference.
(4) Determine the arrangement of the selected air vent installation and connection with the air duct.
