PROBLEM TO BE SOLVED: To perform simultaneous regulation according to indoor environment by a method wherein zone air distributor bodies are integrally arranged on the right and left sides with a body situated at a center and through regulation operation of dampers for air flow regulation and conversion arranged to the respective zone air distributor bodies, cooling, heating, and moistening air in an air flow necessary to the respective zones are distributed and fed. SOLUTION: Return air from the interior of a room, filtered by a prefilter 15 and a main filter 16 arranged in a body A, and external fresh air flow in respective zone machine bodies through ventilation ports 7 and 10 of respective zone air distributor bodies B and C through a blast passage 6 by a single damper motor through operation of zone air distributors B and C through operation of a damper D for varying OA and RA. The return air and the fresh air are heated to a proper temperature, moistened and an air flow is regulated by cooling and heating coils 11 and 12, and a heat-exchange coil 8 for both cooling and heating. Cooling, heating, and moistening air of an air flow and a quantity of heat, needed by each of a plurality of zones are simultaneously fed through opening and closing operation of dampers 9a, 9b and 14a, 14b for conversion. Thus, distribution and feed are practicable by a single air-conditioner. |
