護装置。[Claims for Utility Model Registration] (1) A compressor, a drive unit that changes the operating capacity of the compressor based on a signal, and a drive unit that detects the current flowing through the compressor and starts compressing when the current value is greater than a predetermined value. An air conditioner having an overcurrent protection section that reduces the operating capacity of the machine, an outside air temperature detection section that detects outside air temperature, and an outside air temperature detection section that increases the current value when the temperature detected by this detector is equal to or higher than a predetermined temperature. A protection device for an air conditioner, characterized by comprising a compensation section. (2) A compressor, a drive unit that changes the operating capacity of this compressor based on a signal, and an overcurrent that detects the current flowing through the compressor and reduces the operating capacity of the compressor when this current value exceeds a predetermined value. The air conditioner has an outside air temperature detection section that detects outside air temperature, and an outside air compensation section that lowers a predetermined value of the overcurrent protection section when the temperature detected by the detector is equal to or higher than a predetermined temperature. A protection device for an air conditioner characterized by:
