の発停を自動的に行う。EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. In the figure, reference numeral 1 denotes arithmetic means having a built-in automatic control function, to which a scheduled operation time is inputted from time setting means 2. In addition, a command for forced operation or forced stop that has priority over scheduled operation is input to the calculation means 1 from the remote start/stop means 3 attached outside the air conditioner main body 6. Note that these forced commands are used for operations outside the normal schedule, that is, for overtime work or when a fire occurs. Therefore, the calculation means 1 performs these scheduled operations and

。Therefore, at this time, if the safe operation setting means 6 is set in advance to automatic stop mode, the air conditioner 6 will automatically stop regardless of whether it is running or stopped, and the air conditioner 6 can be safely operated. It becomes possible to carry out maintenance. In addition, if it is necessary to check the inside of the air conditioner 6 while operating the air conditioner 6, by setting the safe operation setting means 6 to the inspection operation mode, the air conditioner can be operated with the inspection door 4 open. It becomes possible to check the inside of aircraft 6.
