PURPOSE:To aim at improvement in cooling efficiency, by constituting an air conditioner so as to prohibit the closure of an outside air inlet at a time when the outside air is less than the specified value with maximum cool and a refrigerant compressor is turned on, in case of the inside air circulating quantity-outside air intake quantity automatic control type air conditioner. CONSTITUTION:A max-cool setting signal is inputted into a controlling device 400 from a max-cool setting device 100, and an operating mode from a compressor operating mode judging device 200, respectively. On the other hand, outside temperature to be detected by an outside air sensor 29 is inputted into an outside temperature judging device 300, and if it is less than the specified value, a judging signal is inputted into a controller 400 outputs a signal prohibiting the closure of an outside air inlet 3 to an inside-outside air adjusting device 500 when a compressor is operated and of a max-cool mode and that the outside temperature is less than the specified value. With this constitution, even at time of the max-cool mode, the outside air is utilized for cooling, thus cooling efficiency is improved. |
