PURPOSE:To shorten a distance between an air blower and a heat exchanger and to prevent the overheat of an electric motor by a structure wherein an air passage on the air blower suction side is divided into two branch passages, and the heat exchanger is provided in one branch passage on the side where the electric motor for the air blower is not installed, while a static pressure regulating damper is provided in the other branch passage. CONSTITUTION:An air suction port 3 and an air discharge port 4 are formed in a casing 2 mounted on a cealing 1, and a rough dust filter 5 is provided at the port 3 and a high performance filter 6 is provided at the port 4. Within the casing 1, a partition plate 7 is planted adjacent the port 4, and an air discharge pipe 9 is opened to the partition plate 7. The air passage of the air blower 8 on the air suction side is divided into two branch passages by another partition plate 10, and the heat exchanger 12 is provided in one branch passage on the side where the electric motor for the air blower is not installed, whereas the static pressure regulating damper 13 is provided in the other branch passage. The air suctioned by the operation of the air blower 8 is divided into the respective air passage, and then joined to be discharged into a room out of the air discharge port 4. |
