Title:
可変容量コンプレッサのトルク算出装置およびトルク算出方法
Document Type and Number:
Japanese Patent JP4580816
Kind Code:
B2
Abstract:
An apparatus for calculating torque of a variable capacity compressor (8), comprising: a sensor (20, 21) configured to detect internal and external states of an air conditioner (6); an OFF-torque calculator (205) configured to calculate and store a steady-state torque according to a state detected by the sensor (20, 21) just before a clutch (43) is turned off; a start torque calculator (209) configured to calculate a start torque according to a state detected by the sensor (20, 21) after the clutch (43) is turned on; a steady-state full-stroke calculator (207) configured to calculate a steady-state full-stroke torque, based on an assumption that the compressor was in a full-stroke-state according to a state detected by the sensor (20, 21) after the clutch (48) is turned on; and a determiner (217) configured to provide, when an elapsed time after the clutch (43) is turned on is less than a predetermined time, a maximum one of the torque values calculated by the OFF-torque calculator (205), start torque calculator (209), and steady-state full-stroke calculator (207).
