Title: AIR-CONDITIONING DEVICE
Abstract:
This air-conditioning device has a control device that controls a refrigerant circuit and a temperature detection device that detects temperature information showing the temperature of the refrigerant circuit. The control device determines the difference between the temperature information when power is restored after a power failure and the temperature information when the power failure is detected by a power failure detection unit. If the determined difference is greater than a power failure reference threshold value, the control device performs compressor protection control to heat a compressor for a certain period of time, and then rotationally drives the compressor. However, if the determined difference is the power failure reference threshold value or less the control device rotationally drives the compressor without performing the compressor protection control.
