Abstract

The invention discloses an air conditioner, which includes an indoor unit; an outdoor unit, the outdoor unit at least includes an outdoor fan; a controller, the controller at least controls the outdoor fan; a fan speed detection device, which is compatible with the controller The electrical connection is used to detect the speed of the outdoor fan; the controller is used to: obtain the current speed of the outdoor fan in a natural state through the fan speed detection device; according to the current speed and the set speed The comparison results between determine the corresponding relationship between the starting current of the fan and the current speed, the set speed, and the set minimum starting current; based on the corresponding relationship, the starting current of the fan corresponding to the current speed is obtained; control the outdoor The fan is started with the fan starting current. The invention changes the way of starting the outdoor fan with a fixed current, and improves the reliability of starting the outdoor fan.

Description

technical field [0001] 本发明涉及空调技术领域,尤其是涉及一种空调器及室外风机启动控制方法。 Background technique [0002] 现有的空调器在启动室外风机时,采用固定电流启动室外风机的方式。由于考虑到启动前的风机处于逆风运转状态等可能发生的任何情况,需通过实验测试以获得风机即使处于最恶劣的情况都能正常启动的固定电流值。在开环启动过程中,由该固定电流产生的力矩拖动电机转动,以逆风启动风机转动并进入转速闭环控制,但是在无逆风状态时,若仍然采用该策略,由于固定电流产生的风机力矩远大于风机负载力矩,从而导致风机转速上升过快,在高于预定的目标转速后才进入转速闭环控制以设定转速运行,导致风机启动时出现噪音。 Contents of the invention [0003] 本发明提供一种空调器,以解决现有的空调器以固定电流启动风机的技术问题,本发明改变了以固定电流启动室外风机的方式,提升了室外风机启动的可靠性。 [0004] 为了解决上述技术问题,本发明实施例提供了一种空调器,包括: [0005] 室内机; [0006] 室外机,所述室外机至少包括室外风机; [0007] 控制器,所述控制器至少控制所述室外风机; [0008] 风机转速检测装置,其与所述控制器电连接,用于检测所述室外风机的转速; [0009] 所述控制器,用于: [0010] 通过所述风机转速检测装置获得自然状态下的所述室外风机的当前转速; [0011] 根据所述当前转速与设定转速之间的比较结果确定风机启动电流与所述当前转速、所述设定转速、设定最小启动电流的对应关系; [0012] 基于所述对应关系得到对应所述当前转速的风机启动电流; [0013] 控制所述室外风机以所述风机启动电流启动。 [0014] 作为优选方案,所述控制器,还用于: [0015] 根据所述当前转速与设定转速之间的比较结果确定第一系数; [0016] 根据所述第一系数确定风机启动电流与所述当前转速、所述设定转速、设定最小启动电流的对应关系为: [0017] Iqoset=(Nx0-Nx)*A+Iq00 [0018] 其中,Iqoset表示风机启动电流;Nx0表示设定转速;Nx表...
