PROBLEM TO BE SOLVED: To easily prevent hot exhaust air being discharged from the outlet of an outdoor machine from flowing back to a fresh air suction port by providing a wind direction deviation frame that is mounted to the outlet of the outdoor machine being surrounded by a sound-arresting panel and a U-shaped connection frame that can be mounted in connection with its deviation side. SOLUTION: An outdoor machine is installed on a floor surface such as a roof along the outer wall of a building and at the same time is surrounded by a three-side sound-arresting panel 7. The three-side sound-arresting panel 7 is composed by connecting a front panel and two side panels in the same structure in a U shape. In a wind direction deviation frame 20, a plurality of air current guide plates that are tilted or curved in a deviation direction are arranged and fixed at nearly a constant interval between a pair of side plates. Although a width plate 27 of a fixed U-shaped connection frame 26 that is connected to a deviation side end face 25 of the deviation frame 20 has the same width as the deviation frame, the depth of a side plate 28 is approximately two times larger than the depth of the deviation frame. The height of the connection frame 26 may be higher than the upper end of the sound-arresting panel 7, at least, by approximately 10 cm. |
