The invention discloses a compressor rotating speed control method based on VCU control, which comprises the following steps: when an air conditioner is started, the VCU controls a compressor to be started at a fixed rotating speed N1, the VCU periodically collects the temperature T1 of a compressor body, the real-time rotating speed N of the compressor, the indoor expected temperature T2 adjustedby a driver, and detects the difference deltaT1 between the real-time temperature T3 of a cockpit and the indoor expected temperature T2; the deltat1 at the moment is calculated according to the temperature data of the VCU collection moment before each period after the air conditioner is started, and if the deltaT1 is larger than or equal to a set temperature threshold value, a rapid cooling strategy is started; and if the deltaT1 is smaller than a set temperature threshold value at the moment, a temperature equalization action strategy is entered at the moment. The rotating speed of the compressor is more reasonable, the temperature fluctuation of the cockpit is small, and the temperature experience of a user is improved.

    本发明公开了一种基于VCU控制的压缩机转速控制方法,包括:在空调开启时,VCU控制压缩机以固定转速N1开启,VCU周期性的采集压缩机本体温度T1与压缩机实时转速N,驾驶员调节室内期望温度T2,检测驾驶舱实时温度T3与室内期望温度T2差值△T1;空调开启后的每个周期开始前根据VCU采集时刻的温度数据计算出此时的△T1,如果△T1大于等于设定温度阈值,则进入快速降温策略;若此时△T1小于设定温度阈值则此时进入均温作用策略。本发明使得压缩机转动速度更加合理且可以使得驾驶舱温度波动较小,提高用户的温度体验。
