Abstract

A ventilating system is provided with openings through which injection is performed. These openings are provided with motor-driven regulating means 4, 5 for regulating the size of the openings in dependency of room thermostats RT. In the duct system 1 of the ventilating system, motor-driven flap means 7, 15 are inserted for maintaining approximately constant pressures ahead of the injection openings. Said flap means 7, 15 are regulated by the static pressure prevailing at the places in the duct system 1 where the pressure is to be kept constant. In order to control the flap means regulating the pressure at the places where it is to be kept constant, in a cheap and simple way, a partial air flow is led out from said places in the duct system 1. Said partial air flow is guided past the sensor for an electric air speed meter and from there to the free atmosphere. The output signal from the air speed meter is utilised in controlling said flap means. <IMAGE>
