PURPOSE:To make it possible to freely adjust the direction of blow-off air on the indoor side, and to constantly secure a blow-off port thereby to prevent any machine from causing a fault by using a centrifugal type fan for an indoor fan, providing blow-off ports at the front, both side surfaces and the upper surface of the main body of a product, and providing doors to respective blow-off ports except one or more blow-off ports. CONSTITUTION:The length of an outdoor fan 6 is shortened to charge the same with ventilation at the lower part of an outdoor heat exchanger 3. A second outdoor fan 9 is charged with ventilation at the upper part of the outdoor heat exchanger 3. Two fans emit a predetermined quantity of air flow. Since an indoor fan 7 is a turbo fan, a blow-off port 8A is provided downward to improve the temperature distribution in the residential space during the space heating operation. In this case, during the space heating operation, when it is desired to further warm the feets, doors 10B, 10C and 10D are closed, and air is blown off only by a front blow-off port 8A. When it is desired, during a cooling operation, not to cool the feet, doors 10B and 10C are closed, and a vane 11 vertically changing air flow direction is directed upward, and air is blown off only through an upper surface blow-off port 8D and a front surface blow-off port 8A. |
