摘要： PURPOSE:To effectively air-condition a room with a plurality of indoor units by reducing the difference in capacity between them when they are operated with a difference of a set air conditioning capacity or more. CONSTITUTION:Microcomputers 13, 25 suitably decide a driving frequency of a compressor based on a difference between a set temperature input from operating units 9, 21 and a room temperature detected by room temperature detectors 11, 23 during air conditioning, and decide an Hz code based on the frequency. The microcomputers 13, 25 compare an Hz code of other indoor unit with an Hz code decided by itself before an operation transfer by the suitably decided frequency. They so corrects downward the decided code as to fall within the set code when the own code is a higher level by the preset code or more than the code of the other indoor unit and operate. Thus, since the indoor units do not interfere with one another, a room can be air conditioned with uniform temperature distribution.

摘要： PURPOSE:To provide effective air conditioning by controlling a diffusing angle and/or diffusing air flow rate of diffusing air from an indoor unit in response to a volume of a detected room. CONSTITUTION:When microcomputers 13, 25 detect that a room temperature becomes a first predetermined temperature difference from a set temperature, they store this time (t1). Heating is advanced, and when the microcomputers 13, 25 detect that the room temperature is raised to a second predetermined temperature difference from the set temperature, they store this time (t2), and obtains a time ¦t2-t1¦ from the first difference of the room temperature to the second difference. The microcomputers 13, 25 compare the time ¦2-t1¦ with a reference time, and decides whether a space to be air conditioned of the room is wide or not. The microcomputers 13, 25 control, if the room is not wide, normal diffusing, but so regulate, when judging that the room is wide, a diffusing angle that the diffused air reaches farther, and also regulates a diffusing air flow rate as required.

摘要： PURPOSE:To effect the comfortable humidifying control of a room and prevent condensation by a method wherein the humidification is controlled by detecting a room humidity, room temperature, outside air temperature and the like. CONSTITUTION:Upon starting humidifying control, humidity control of much humidifying amount is effected for a predetermined period of time in spite of a room humidity detected by a humidity sensor 3, then, humidifying control of less humidifying amount is effected subsequently until a room temperature is approached to a desired set temperature and, thereafter, a humidifier 5 is controlled so that a room humidity becomes equal to a desired set humidity. When an outside air temperature detected by an outside air temperature sensor 6 is lower than a predetermined temperature, the humidifier 5 is controlled so that the room humidity is reduced to a value lower than a desired set humidity. Further, a relative body feeling humidity information, including slightly humidifying and more humidifying, is inputted by an operating unit 11 and the humidifier 5 is controlled based on the relative body feeling humidity information and the room humidity detected by the humidity sensor 3. According to this method, the humidity in the room can be controlled at the desired optimum humidity.
