The operation speed storage device, the compressor suction operation according to the output of the indoor suction set temperature determining means and the suction temperature measuring means. Switching the plurality of working rotational speeds stored in the rotational speed memory means those having a compressor operation rotational speed changing means.

Further, in the above-mentioned contents, the suction temperature conversion amount storage means is provided with a plurality of suction temperature conversion amount storage means for converting the set temperature of the room temperature according to cooling and heating.

[0008]

The operation of the above technical means is as follows.

According to the present invention, since the number of revolutions of the compressor is changed in accordance with the radiant heat assumed by the operating time and the suction temperature at the start of operation, the present invention does not cause the user discomfort and reduces the power consumption. It becomes possible to reduce.

Further, by storing different set temperature conversion amounts during the cooling operation and the heating operation, the suction set temperature can be set in accordance with the characteristics of the radiant heat during each operation, and the power consumption can be reduced. You can

Is.

The operation of the above arrangement will be described below. When the operation of the air conditioner is started, the indoor set temperature set by the user is stored in the set temperature storage means 3. Further, the suction temperature measurement means 1 installed on the suction side of the indoor unit of the air conditioner measures the suction temperature at the start of operation and stores it in the operation start suction temperature storage means 2. Then, based on the elapsed time from the start of the operation measured by the time measuring means 5 and the suction set temperature stored in the set temperature storage means 3, the set temperature conversion amount stored in the set temperature conversion amount storage means By switching the suction set temperature by the indoor suction set temperature determining means 5 in the microcomputer, the suction set temperature can be switched between time and suction temperature at the start of operation. The compressor operating speed changing means 8 stores in advance the compressor operating speed in the compressor operating speed storing means 7 so that the suction set temperature matches the suction temperature measured by the suction temperature measuring means. Switch to multiple operating speeds. As described above, the rotational speed of the compressor is changed in accordance with the radiant heat assumed by the operating time and the suction temperature at the start of the operation, so that it is possible to reduce the power consumption without giving the user discomfort.
