場合、ファン１０４に吸込まれた風は上吹出口１０２か
ら吹出されるとともに開閉部材１０５の開動作により下
吹出口１０３からも吹出される。In the figure, in the case of cooling operation, the air sucked into the fan 104 is blown out from the outlet 102. Further, in the case of heating operation, the air sucked into the fan 104 is blown out from the upper outlet 102 and also blown out from the lower outlet 103 by the opening operation of the opening/closing member 105 .
発明が解決しようとする問題点

あった。Problems to be Solved by the Invention In the conventional configuration as described above, if cold air is blown out from both the upper and lower air outlets during cooling operation, the cooling effect can be increased.
Blowing out cold air at low wind speed and low air volume from the lower outlet has the problem of worsening the cooling feeling except at the start of operation, and also requiring measures to prevent condensation around the lower outlet.
本発明は以との点に鑑みて、熱交換器温度が所定温度以
上でかつ下フアン風量が多い場合すなわち、上フアン風

による水洩れ防止を可能とするものである。In view of the following points, the present invention opens the lower outlet when the heat exchanger temperature is higher than a predetermined temperature and the lower fan air volume is large, that is, the upper fan air volume is also large and high cooling capacity is required. Conversely, when the heat exchanger temperature is below the specified temperature and the lower fan air volume is low, the lower air outlet is closed, ensuring high cooling capacity after the start of operation and improving the feeling during weak operation. This makes it possible to prevent water leakage due to condensation around the lower air outlet and the lower air outlet.
