Title:
可変容量型圧縮機
Document Type and Number:
Japanese Patent JP6711336
Kind Code:
B2
Abstract:
This variable displacement compressor is provided with: a compression mechanism (12); a volume control mechanism (40) for controlling the volume of discharge of a refrigerant from the compression mechanism; a clutch (MGC); and a control device (100) for controlling the volume control mechanism and the clutch to switch between operating modes. The compression mechanism is provided with a volume limiting section for limiting the lower limit of the volume of discharge, to an intermediate volume which is greater than a minimum volume and smaller than a maximum volume. The control device can switch the operating mode to a variable operation mode and an intermittent operation mode. The variable operation mode is an operating mode in which the volume of discharge is changed by the volume control mechanism in a range from the lower limit volume to the maximum volume. The intermittent operation mode is an operating mode in which the state of connection is intermittently switched to a connected state and a disconnected state by the clutch while the volume of discharge is controlled to the lower limit volume by the volume control mechanism.
