Abstract

1,001,560. Ventilation. SVENSKA FLAKTFABRIKEN A.B. May 23, 1962 [May 25, 1961], No. 19916/62. Heading F4V. In a ventilating system comprising a distribution duct 3, a fan 2 and two or more air outlets 4, 5 adjusted by means of dampers and located at a relatively large distance from the fan, a device is provided for maintaining constant the static pressure in the duct near the outlets, the device consisting of a pressuresensitive means 6 connected to a branch duct narrow in relation to the main duct 3 and disposed close to the fan outlet, the pressuresensitive means 6 controlling a fan output adjusting device 12 through a servomotor 7. Upstream of the means 6 in the branch duct there is a throttle 9 having similar pressure-fall characteristics to that of the distribution duct up to said air outlets and in the outlet of the branch duct a damper 10 operated by the pressure-sensitive means 6 so that the position of the damper 10 will correspond approximately to the average position of the dampers of the air outlets. In operation if dampers of the air outlets are nearly all closed the air consumption will be small, and the output of the fan will be reduced to maintain the desired static pressure near these outlets. The setting of the throttle 9 is adjustable.
