The invention discloses a control method and a control system for a direct-current fan of a vehicle-mounted refrigerator. The control method comprises the following steps: calculating a rotating speed standard range according to a rotating speed standard value and a tolerance value; acquiring a rotating speed calibration value; enabling the rotating speed calibration value to be equal to the rotating speed standard value; and detecting the pipeline temperature of the compressor, and when the to-be-detected temperature is greater than a first temperature threshold value, controlling the current rotating speed of the direct-current fan to be set as [rotating speed calibration value * (output percentage + 10%)]. According to the technical scheme, firstly, the rotating speed calibration value of the direct-current fan in the vehicle-mounted refrigerator is set within the rotating speed standard range, and in the running process of the vehicle-mounted refrigerator, whether the rotating speed of the direct-current fan needs to be changed or not is judged by detecting the temperature of a compressor pipeline; and the current rotating speed of the direct-current fan is controlled to be set as [rotating speed calibration value * (output percentage + 10%)], so that the heat dissipation efficiency of the compressor is improved, the temperature of the compressor is kept in a better range, and electric energy is effectively saved.

    本发明公开了一种车载冰箱的直流风扇控制方法以及控制系统,控制方法包括根据转速标准值以及公差值计算转速标准范围;获取转速标定值;令所述转速标定值等于所述转速标准值;检测压缩机管路温度,待测温度大于第一温度阈值时,控制直流风扇的当前转速设定为[转速标定值*(输出百分比+10%)]。本技术方案首先将车载冰箱内直流风扇的转速标定值设定在转速标准范围内,在车载冰箱运行过程中,通过检测压缩机管路温度判断直流风扇转速是否需要进行更改,当检测到压缩机管路温度过高时,控制直流风扇的当前转速设定为[转速标定值*(输出百分比+10%)],从而提高压缩机的散热效率,保证压缩机温度维持在较佳的范围,而且有效地节约电能。
