Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/158693
Kind Code:
A1
Abstract:
The present invention has: a compressor (7) that constitutes a refrigerant circulation circuit; a control unit (30) provided with an input current detection circuit (11) for detecting the input current of the compressor (7), and a microcontroller (1) for generating the drive signal of the compressor (7) and calculating the input power of the compressor (7) on the basis of the input current; and a vibration sensor (10) for detecting the vibration of piping included in the compressor (7). The control unit (30) is provided with a memory medium (12) for associating the compressor frequency with the input power at which the vibration detected by the vibration sensor (10) is determined to be abnormal vibration and storing the compressor frequency and the input power, and the control unit (30) performs a frequency jump control that sets the compressor frequency stored in the memory medium (12) as a jump frequency at which operation of the compressor is avoided.
