近年来我国制冷事业发展很快.冷库制冷工艺自动控制亦得到了广泛的应用,不但新建冷库具有一定的自控程度,而且老库也在不断改造中实现自动控制,从而达到了生产安全,节省劳力和运行经济的目的。我国冷库制冷工艺自控虽然发展很快,但毕竟应用时间不长,经验不足,尚处在 In recent years, China’s refrigeration industry has developed rapidly.Automatic control of cold storage refrigeration process has also been widely used, not only has a certain degree of self-control of the newly built cold storage, and the old library is also in the continuous transformation to achieve automatic control, so as to achieve the production safety and labor saving And the purpose of running the economy. Although the rapid development of China’s cold storage refrigeration process control, but after all, the application of time is not long, lack of experience, still in
