  • control device for the air conditioner executes the defrosting operation according to a flowchart shown in Fig. 3 .

Specifically, if a temperature detected by the outdoor heat exchanger temperature sensor 38 as described above is lower than the defrosting requiring temperature, it is determined that the defrosting is required. If the defrosting is required, the flow proceeds to step S20. If not, the flow proceeds to RETURN and goes back to START.
  • step S20 the control device calculates a heat quantity (compressor-generated heat quantity) Qc generated by the compressor 6.
  • the duration time of defrosting operation is determined by various conditions such as a temperature inside the outdoor heat exchanger, a compressor power set by the user (e.g., a power corresponding to an air flow rate set by the user), an outside air temperature (for this, an outside air temperature sensor is provided), a temperature of the indoor heat exchanger at a start of defrosting operation (i.e., heat quantity held by the indoor heat exchanger at a start of defrosting operation), and the like.

  • step S50 the control device determines a rotation speed N of the indoor fan 34 based on the heating-distributable heat quantity Qh calculated in step S40.
  • control device exerts control so that even if the heating-distributable heat quantity Qh becomes smaller in the defrosting operation, the indoor fan 34 is rotated at more than a specified least rotation speed. That is, the indoor fan 34 is not fully stopped (the rotation speed N is not set to zero).
  • an indoor user actually obtains a feeling of heating not only by directly receiving actual heat quantity (warm air) fed from the indoor unit 4 into the room, but also from air flow sounds (wind flow sounds) or rotational sounds of the indoor fan 34 without direct reception of the warm air from the indoor unit 4. Accordingly, as the rotation speed N of the indoor fan 34 becomes zero, the user may feel uncomfortable by feeling a heating stop.
  • the control device exerts control so that even if the heating-distributable heat quantity Qh becomes small in the defrosting operation, the indoor fan 34 is rotated at a specified least rotation speed, i.e. such a rotation speed that the user can obtain a feeling of heating.

  • the indoor fan 34 blows air into the room during the execution of defrosting of the outdoor heat exchanger 14.
  • the defrosting of the outdoor heat exchanger 14 can be executed without causing the user to feel uncomfortable by regarding a stop of the indoor fan 34 as a stop of heating.
  • a heat quantity distributable to the heating is calculated based on a heat quantity necessary for melting of frost on the outdoor heat exchanger 14, a power of the compressor 6, and a defrosting duration time, and the rotation speed of the indoor fan 34 is controlled based on the calculated heat quantity. Therefore, the rotation speed of the indoor fan 34 can be controlled with preference given to the defrosting.
  • the indoor fan 34 can provide air blow with users avoided in the defrosting operation. As a result, the possibility that the users may feel uncomfortable due to direct reception of low-temperature air is suppressed.
  • the air conditioner of the above embodiment includes the motion sensor 40 for detecting a position of a human (user) in a room.
  • the louver directs the air flow blown from the indoor fan to an upward direction in the room (e.g., toward the ceiling).
  • the possibility that the users may feel uncomfortable is suppressed as in the case where the motion sensor is included.
  • an outdoor temperature sensor for detecting outdoor temperature is provided so that the rotation speed of the indoor fan can be controlled based on an outdoor temperature detected by the outdoor temperature sensor.
  • the heat quantity required for defrosting becomes higher under a lower outdoor temperature, than in cases of higher outdoor temperatures. Accordingly, under a lower outdoor temperature, it is preferable to exert control so that the rotation speed of the indoor fan becomes lower than those of higher-temperature cases, thereby allowing larger amounts of heat to be supplied to the outdoor heat exchanger.
  • the present invention is applicable not only to such air conditioners composed of an outdoor unit and an indoor unit as in the above-described embodiment but also to integrated type air conditioners in which an outdoor unit and an indoor unit are integrated.
