The invention provides a protection method and device for an air conditioner compressor and engineering machinery, and is applied to the technical field of vehicle control, the method comprises the following steps: acquiring the duration of stopping the operation of the air conditioner compressor, and when the duration of stopping the operation of the air conditioner compressor is greater than or equal to a first preset duration, generating first prompt information, the first prompt information is used for reminding a user to confirm whether the compressor enters an oil return mode or not, and when first confirmation information indicating that the compressor enters the oil return mode is received, the gear of the engine is controlled to be a preset gear and is kept at the preset gear within a second preset duration, and the compressor is controlled to operate for the second preset duration. Whether the compressor enters the oil return mode or not is determined according to the running stopping duration of the air conditioner compressor, and when it is determined that the compressor enters the oil return mode, oil return of the compressor is achieved, internal abrasion of the compressor is reduced, and an air conditioner system is protected by controlling the gear of the engine and running of the compressor.

    本申请提供一种空调压缩机的保护方法、装置、工程机械,应用于整车控制技术领域,所述方法包括:获取空调压缩机停止运行的时长,当空调压缩机停止运行的时长大于或等于第一预设时长时,生成第一提示信息,所述第一提示信息用于提醒用户确认压缩机是否进入回油模式,当收到表示压缩机进入回油模式的第一确认信息时,控制发动机的档位为预设档位,且在第二预设时长内保持在所述预设档位,并控制压缩机运转,且运转第二预设时长。本申请根据空调压缩机停止运行的时长,确认压缩机是否进入回油模式,在确认进入回油模式时,通过控制发动机的档位和压缩机运转,实现压缩机回油,降低压缩机内部磨损,保护空调系统。
