PURPOSE:To equalize the balance of the amount of air and the blow-off air speed distribution in respective blow-off ports, by a method wherein the first and second blow-off air passages of a chamber are divided into a plurality of blow-off passages from the upstream to the downstream of the blow-off port, in the title air-conditioning machine of two-direction blow-off type. CONSTITUTION:Conditioning air is sent to an air inflow port 15g by a fan from the blowing passage 15a of a chamber 15 through a heat exchanger and, thereafter, is distributed to first and second blow-off passages 15b, 15c. In this case, the amount of air is distributed equally substantially since the air is distributed into both blow-off passages 15b, 15c in accordance with the ratio of respective passage resistances. Further, the first blow-off passage 156 is divided lengthwise by a partitioning plates 15i and the second blow-off passage 15c is divided lengthwise by the partitioning plates 15j, 15k into independent divisions. Accordingly, the conditioning air may be blown off through respective blow-off ports with equal distributions of airflow amount and air speed in spite of different resistances of respective blow-off passages 15b, 15c. |
