Output power control method and system under refrigeration mode of excavator air conditioner
The invention discloses an output power control method and system under a refrigeration mode of an excavator air conditioner. The method comprises the steps of obtaining a working pressure of an air conditioner compressor according to a working state of the excavator air conditioner in the refrigeration mode, controlling an output flow of hydraulic oil through controlling an output rotating speedof a power device and a displacement of the hydraulic oil, and then controlling the power device to drive the air conditioner compressor to work at a target output power. The output rotating speed ofthe power device and the displacement of the hydraulic oil are controlled through a complete machine controller, so that the power device is controlled to drive the air conditioner compressor to workat the target output power, power loss caused by rotation of the air conditioner compressor is accurately controlled, power loss of an engine is reduced, and oil consumption is reduced.
本发明公开了一种挖掘机空调制冷模式下输出功率控制方法及系统，包括：根据挖掘机空调制冷模式的工作状态，获取空调压缩机的工作压力，通过控制动力装置的输出转速和液压油排量控制液压油输出流量，以此控制动力装置以目标输出功率驱动空调压缩机工作。通过整机控制器对动力装置的输出转速和液压油排量的控制，以此控制动力装置以目标输出功率驱动空调压缩机工作，对空调压缩机转动导致的功率损耗进行精确控制，降低发动机功率损耗，从而降低油耗。
