PROBLEM TO BE SOLVED: To condition air inside an apparatus by generating control air flow by a method with a higher energy-saving effect irrespective of a temperature outside an apparatus body.SOLUTION: An air conditioner includes: air conditioning means 3; an outward channel 4a that guides an air from the air conditioning means 3 to environment control portions 2-1 and 2-2; a return channel 4c that passes the air after heat exchange from the environment control portions 2-1 and 2-2 via the air conditioning means 3 to the outside or directly to the outside of the device; a first communication path 4c1 that branches from the return channel 4c and has a first outside air port 7 opening toward the outside of the device; and a second communication path 4c2 that branches from the return channel 4c and has a second outside air port 8 opening toward the outside of the device. The air conditioner compares a temperature inside the return channel 4c with a temperature outside the device, and switches between a route passing a third communication path 4c3 that is the return channel 4c, and a route to discharge air from the second outside air port 8 of the second communication path 4c2 and take in the outside air from the first outside air port 7 of the first communication path 4c1, on the basis of a comparison result. |
