PCT No. PCT/FI90/00010 Sec. 371 Date Aug. 17, 1990 Sec. 102(e) Date Aug. 17, 1990 PCT Filed Jan. 11, 1990 PCT Pub. No. WO90/08293 PCT Pub. Date Jul. 26, 1990.The present invention concerns a procedure and apparatus for controlling and maintaining air currents or equivalent in an air-conditioning installation or equivalent. The air-conditioning installation comprises one or several air-conditioning machines (P) for producing the desired flows, and one or several duct systems for conducting the flows into the desired room spaces (H1,H2 . . . ) or equivalent and/or out from the room spaces (H1,H2 . . . ) or equivalent. The duct systems consist of requisite trunk, zone and room duct systems (R,Z,C). In the procedure the air flow rates required at any given time in the air-conditioning system are determined on the basis of the air temperature and/or air quality and/or air noise levels and/or air pressure conditions and/or other similar factors. On the basis of the respective air flow rates determined by calculation, a combination of the set values for all control members (S1,S1.1,S1.2 . . . ) and air-conditioning machines (P) are thereafter determined at the same time, and the control members (S1,S1.1 . . . ) and the air-conditioning machines (P) are at the same time set to settings consistent with said set value combination, whereby the above mentioned air flow rates will be realized.
