可变容量压缩机的控制装置和计算该压缩机的转矩的方法
摘要：
提供了一种计算可变容量压缩机转矩的装置。该压缩机包括吸入室；缸膛；排出室；将冷却剂从吸入室抽至缸膛，压缩抽出的冷却剂并将压缩的冷却剂排出至排出室的活塞；离合器，其打开用以传输驱动源的驱动力至活塞从而驱动活塞，以及关闭用以将驱动源的驱动力从活塞断开从而停止活塞运动；以及调节从排出室引入至活塞后的后压力从而调节活塞冲程的压力调节器。该装置包括计数器，用于在离合器被关闭至下次打开的时间内计数关闭时间；判决器，用于判断关闭时间是否少于预定时间；和开始转矩计算器，用于根据判决器的判断计算压缩机的开始转矩。
摘要（英）：

An apparatus for calculating torque of a variable capacity compressor is provided. The compressor includes a suction chamber, a discharge chamber, a piston to draw coolant from the suction chamber, compress the drawn coolant, and discharge the compressed coolant into the discharge chamber, a clutch to be turned on to transmit driving force from a driving source to the piston so that the piston operates and to be turned off to disconnect the driving force of the driving source from the piston so that the piston stops, and a pressure adjuster to adjust a back pressure introduced from the discharge chamber to the back of the piston and thereby adjust a piston stroke. The apparatus comprises a counter configured to count an OFF time when the clutch is tuned off from an ON state until the clutch is next turned on, a determiner configured to determine whether or not the OFF time is less than a predetermined time, and a start torque calculator configured to calculate a start torque of the compressor depending on the determination of the determiner.
