摘　　要：根据船用高、低温冷库温度一般采用温控器进行双位控制所存在的一些缺点,提出采用PLC控制,用变频器来改变压缩机的转速,以改变制冷剂的流量,调节库温、提高温控精度、节省能耗。并用实验结果加以验证。According to the disadvantage existing in which temperature of cold store is regulated by thermostat in the high and low temperature refrigerator system, this paper adopts PLC to adjust the rotation speed of refrigerator compressor and refrigerant flux by changing the output frequency of the transducer so as to adjust temperature of cold store and improve the precision of temperature control and save energy, and that it is verified by experiments.
