AIR CONDITIONER
FIG3 is a flowchart showing a flow of a process of a heating operation control
Next, a drive control of the compressor 21, the outdoor fan 27 and the indoor fan 32 in the heating operation (hereinafter, described as heating operation control) will be described in detail using the flowchart shown in FIG3. In FIG3, ST represents a step of a process, and the numbers following this represent a step number. The outdoor unit control means 200 and the indoor unit control means 300 described above constitute the control means of the present invention. Therefore, in the following description of a control and a process including FIG3, the description of the control of the air conditioner 1 will be made mainly by using control means, and the description of the control of the individual device of the outdoor unit 2 and the indoor unit 3 will be made mainly by using (CPU 210 of) the outdoor unit control means 200 and (CPU 310 of) the indoor unit control means 300 appropriately.

['10. The air conditioner according to any one of claims 1 to 9, wherein the indoor unit includes an indoor temperature sensor, the outdoor unit includes an outdoor fan and an outside air temperature sensor, when the temperature increasing operation is performed, the control means drives the outdoor fan at a rotation speed corresponding to a minimum rotation speed of the compressor, when the temperature maintaining operation is performed, the control means drives the outdoor fan at a rotation speed corresponding to a minimum rotation speed of the compressor in a case where an outside air temperature detected by the outside air temperature sensor is lower than a predetermined first threshold outside air temperature, stops the outdoor fan in a case where the detected outside air temperature is equal to or higher than a predetermined second threshold outside air temperature which is a temperature higher than the first threshold outside air temperature, or in a case where the detected outside air temperature is equal to or higher than the first threshold outside air temperature and lower than the second threshold outside air temperature and an indoor temperature detected by the indoor temperature sensor is equal to or higher than a predetermined threshold indoor temperature, and drives the outdoor fan at a predetermined outdoor fan rotation speed when maintaining a temperature in a case where the detected outside air temperature is equal to or higher than the first threshold outside air temperature and lower than the second threshold outside air temperature and the indoor temperature detected by the indoor temperature sensor is lower than a predetermined threshold indoor temperature.']
