PROBLEM TO BE SOLVED: To obtain a device for controlling a refrigerant heating type inverter air conditioner which can improve the pressure protection, temperature protection, and the starting performance when the compressor is not warm. SOLUTION: In a refrigerant heating type inverter air conditioner, the refrigerant discharge part of a compressor 12 is provided with a temperature sensor 11. When the detection signal of the temperature sensor 11 is the first high temperature level or higher, the compressor 12 is stopped. When the detection signal is lower than the first high temperature level, and between the second and third high temperature levels, the maximum operating frequency of the compressor 12 is controlled to a predetermined value. Moreover, the intermittent operation of the compressor 12 having the open-phase operation for a predetermined time/the shutdown for a predetermined time as one cycle is repeated during the interval when the detection signal of the temperature sensor 11 becomes the first low temperature level or higher, after it becomes below the second low temperature level at the time of the operation shutdown. |
