We all know that this duct also requires a quantity circulation charge of 0.79m3/s so we will use the velocity and quantity move charge to find the lacking info.
Linear slot diffusers have decreased airflow capacity than directional diffusers. Every single of these provides about 200-250 cfm of airflow only. Should you enable an excessive amount of airflow via a linear slot diffuser, it begins to crank out sounds. In addition to, its vertical toss characteristic could cause uncomfortable if far too much air is blasting on to people’s heads.
