摘要： PURPOSE:To provide an air conditioning device which is suitable for quiet sleep operation and prevents an uncomfortable feeling from being exerted on a user by providing a selecting means to select first and second operation modes. CONSTITUTION:A selecting means 2 to select which of a first operation mode suitable for continuance of operation and a second operation mode suitable for operation during sleeping of a user, and a control part 3 to control blowers 9 and 12, a compressor 6, a 4-way valve 7, and an expansion valve 10 according to control signals transmitted from an operation content input part 1 and the selecting means 2 are provided. A protection control operation in the second operation mode disconnects, unlikely the first operation mode, a power source 4 to a compressor 6 instead of forced high speed rotation of the indoor blower 12. This operation is made so as to be suitable for running during sleeping of a user, and enables prevention of awaking of a user and production of an uncomfortable feeling due to noise and strong air occasioned by high speed rotation of the indoor blower 12 during sleeping.

摘要： PURPOSE:To enable substantial control of indoor air and to enable control of prevention of the occurrence of the overload of a compressor by a method wherein, through control of a louver drive motor in prior to control of an indoor fan and the compressor, the opening of an indoor louver is controlled. CONSTITUTION:A relay 7b is brought into an ON-state so that an outdoor fan 2 is brought into an OFF-state from an ON-state, heretofore kept, according to the increase of a input current value detected by a current detector 11. With this state, operation is effected for a while, and when an input current value is yet increased, the opening of a louver 20 is controlled so that the opening area of a discharge port 19 of the louver 20 is increased. The opening of the louver 20 is regulated in a way that based on a detecting value from a louver angle detector 13, a relay 10 for driving a louver is closed to operate a louver drive motor 5. This constitution increases an airflow discharged through a discharge port 19 even when the number of revolutions of an indoor fan 4 is not changed and increases an amount of heat emitted at an indoor heat exchanger 18, and prevents the increase of an input current.
