PURPOSE:To enable to response to the total change of load by a method wherein simultaneous controlling is performed so as to coincide a detected suction air temperature with a set suction air temperature, to coincide a detected air pressure with a set air pressure and to settle adjustable air flow dampers to set opening degrees. CONSTITUTION:Firstly, the respective required heats of the zones, of which the adjustable air flow dampers 91, 92,... are respectively in charge, and the total heat summing up said required heats are calculated by means of a controlling device 12. Secondly, the optimum air flow of a duct, which can be set beforehand in proportion to the number of the adjustable air flow dampers 91, 92..., and the respective air flows of the adjustable air flow dampers 91, 92... based upon said total heat are determined and as well as the respective opening degrees of the adjustable air flow dampers 91, 92,... are set in accordance with said determined air flows. Thirdly, the static pressure in the duct in proportion to the total air flow summing up the air flows in the adjustable air flow dampers 91, 92,... is set in order to control the air conditioner 1 and the adjustable air flow dampers 91, 92,.... |
