The invention discloses a control method for preventing an automobile air conditioner from frosting. A temperature control point of a compressor is associated with outdoor temperature and fan gears. The specific logic is as follows: when the outdoor temperature is greater than 30 DEG C, T disconnection = T original disconnection + (0-2) DEG C, and T work = T original work + (0-2) DEG C; when the outdoor temperature ranges from 25 DEG C to 30 DEG C, T disconnection = T original disconnection + (0.5-1.5) DEG C, and T work = T original work + (0.5-1) DEG C; when the outdoor temperature is less than 25 DEG C, T disconnection = T original disconnection + (0.5-1) DEG C, and T work = T original work + (0.5-2) DEG C; wherein T disconnection is a new compressor disconnection temperature, T original disconnection is an original compressor disconnection temperature, T work is a new compressor working temperature, T original work is an original compressor working temperature, and T original disconnection is equal to 0.5-4 DEG C; and T original working is equal to 5-8 DEG C. According to the control method, frosting of the automobile air conditioner can be prevented.

    一种防止汽车空调结霜的控制方法,压缩机的温度控制点与室外温度、风机档位关联。具体逻辑为:当室外温度大于30度时,T断开=T原断开+(0~2)℃,T工作=T原工作+(0~2)℃;当室外温度在25‑30度之间时,T断开=T原断开+(0.5~1.5)℃,T工作=T原工作+(0.5~1)℃;当室外温度小于25度时,T断开=T原断开+(0.5~1)℃,T工作=T原工作+(0.5~2)℃;其中T断开为新的压缩机断开温度,T原断开为原压缩机断开温度T工作为新的压缩机工作温度,T原工作为原压缩机工作温度,T原断开=0.5~4℃;T原工作=5~8℃。根据本发明的控制方法,可以防止汽车空调结霜。
