* Airflow Requirements (CFM): The foundational step in any diffuser selection process is to determine the required airflow rate for the spaceGrilles. Circular diffusers. Swirl diffusers. Long throw diffusers. Square diffusers.Linear slot diffusers. Floor diffusers. Fire protection. VAV/VAC. Acoustic.. This is typically expressed in Cubic Feet per Minute (CFM). Accurate load calculations and understanding the CFM for the room where the linear slot diffusers will be installed are crucial. If multiple diffusers are being used, calculating the CFM for each zone is necessary. Charts and tables like a Linear Slot diffuser CFM Chart provide guidance on matching airflow to diffuser performance.作者：K LAWSON·被引用次数：1—5. Diffusers will be selected and laid out based on the comfort criteria T50/L method, where T50 is the diffuser throw length to a terminal ...

* Throw and Air Pattern: The "throw" refers to the distance the air travels before its velocity drops to a specified level.How do I choose a Linear Slot Diffuser? First, we'd recommendfinding out the CFM's that the room the Linear Slot Diffusers will be in, and if using multiple ... For linear slot diffusers, the air pattern can often be adjustable from horizontal to vertical, offering flexibility in directing airflow. Some models offer specialized air pattern controlling deflectors or a hit and miss damper system, allowing users to fine-tune the air distribution.Draw a line from the air flowselectionpoint through the required spigot air velocity and read off the nearest standard spigot size. In this example the spigot ... When using slot diffusers in extract applications, manufacturers often provide a vertical/sidewall projection nomogram to select performance effectively, and throw values might be disregarded.Linear Slot Diffusers

* Noise Levels: Occupant comfort is significantly impacted by noise.Technical Selection Guide HVAC designers must consider the noise generated by airflow through the linear slot diffuser. Manufacturers provide sound data, often expressed in decibels (dB) or Noise Criteria (NC) ratings. For instance, a noise level of >NC25 might be acceptable, but when a noise level correction factor of +4 is applied, it can reach >NC30. The selection guide should detail how to find the sound output level for the selected diffuser.

* Pressure Loss: As air passes through the diffuser, there will be a pressure dropHow to Choose the Right Linear Diffuser Size for Your HVAC System. This value must be factored into the overall system pressure calculations to ensure the fan can deliver the required airflowFlush - mountedlinear diffuser. • Available in 1 to 6slots. • Lengths are available on request. • 180° fully adjustable air flow pattern by mean.. A pressure loss of 29 Pa, for example, might be considered for a specific slot diffuser.
