Description

Technical field

[0001] The present invention relates to an inverter air conditioner, in particular to an inverter air conditioner that limits the operating frequency range of a compressor with a maximum operating frequency determined based on the condensation temperature, and realizes control of the drive of the compressor. The invention also relates to its control method. Background technique

[0002] The air conditioner is a device used for indoor cooling / heating, with dehumidification and quietness functions. An air conditioner that uses a compressor driven by an inverter method is called an inverter air conditioner.

[0003] The inverter air conditioner controls the number of rotations of the compressor according to the load conditions of the cold room or the warm room, and changes the circulation amount of the refrigerant. At this time, the number of rotations of the compressor can be controlled by changing the frequency of the driving power supply of the compressor motor, t...
