PROBLEM TO BE SOLVED: To provide a turbo fan housing for window-type air conditioner which enables the prevention of the drop of wind quantity and static pressure, using a turbo fan excellent in fan efficiency. SOLUTION: In the fan housing 13 of a window-type heat exchanger which is equipped with a flow guide part 131 being equipped with a suction face where a bell mouth for guiding indoor air is made, a bottom face being opposed to the above suction face and having an indoor fan for sucking the above indoor air installed, and a bulkhead being installed between the above suction face and the bottom face and surrounding the above indoor fan, a discharge part 132 being constituted by the above bottom face and the above bulkhead being extended from an open side made on one side of the above flow guide part, and a cut-off part 133 being made inside the bulkhead coupling the above discharge part and the above flow guide part, the above indoor fan is a turbo fan 14, and a passage made of the above turbo fan 14 and the above flow guide part 131 is made to have a change in advance direction, and a part of the dynamic pressure of the indoor air is converted into static pressure at conversion of the direction of the indoor air. |
