Throw Requirement

Ceiling grilles and diffusers recommended for vertical top-down pattern. In some places in the room may need to be cooler than the other. In addition, in some parts of the room can be a difficult condition because air problems. They are used in areas adjacent to the perimeter walls of the places which require localized spot, air conditioning. Ceiling height-12 feet or more in need. Throw for vertical projection largely depends on the temperature of the supply air and the proximity of the surface of the wall.

Sidewall-mounted diffusers and grilles are horizontal values on the basis of a ceiling height of 8 to 10 feet. Diffuser grille or installs in about 1 foot below the ceiling. For this listed throw, air traffic services will increase or decrease inversely proportionally to the height of the ceiling. For the air to adjust the template and air traffic services listed minimum-maximum throw the cost can be decreased by 1 meter 1 meter increase the height of the ceiling above 10 feet. Throw values are furnished by the manufacturer.

When the sidewalls of the grilles are installed remote from the ceiling (more than 3 meters), reduces the nominal throw values 20 percent. The windowsill is mounted diffusers, grilles or have quit values on the basis of 8 to 10 feet high ceilings. This is the outlets are in the top 30 of the century-high window-sill. For this listed throw, air traffic services will vary depending on the height of the ceiling. For the air to adjust the template and air traffic services listed minimum-maximum throw cost can be decreased by 2 metres for every 1 increase ft ceiling height above 10 feet. A decrease of 1 meter 1 meter reduction sill height.

Minimum throw the results of the air traffic services is higher than that obtained when using the maximum throw. Thus, 50 fpm, instead of 35 fpm, is the movement of air. Listed at least throw specifies the minimum distance is recommended. The minimum distance from the diffuser for wall or key barriers, such as a structural beam. The listed maximum throw is the recommended maximum distance to the wall or a large obstacles. Throw values for the sidewalls, ceiling grilles and diffusers and footprint and speed based on flash-ceiling structure to ensure the smooth flow of air path. The listed maximum throw in 1,3 times is the full cast of the air flow. This is where the terminal is equal to the velocity of air velocity. Nominal footprint speeds in the range of 25 to 35 fpm for maximum specified throws and 35 to 50 fpm for the minimum listed throw values.

The cold air falling or warm air in the growth of practical importance in supplying heated or cooled air from the side of the grille. If you throw such that the air stream prematurely included in the occupied zone, significant project can be experienced. This is due to incomplete mixing. Total troops must be considered when the wall grille is located at a distance from the ceiling. Chilled dropping controlled interval walls, bars on the ceiling and setting up the lattices of the 15th century the Warm air fuelled largely contributes to temperature stratification in the upper part of the room. The minimum distance between the grating and the ceiling should be 2 ft or more. Minimum mounting division must be at least 2 feet or more. Minimum installation height must be 7 feet...
