一、前言最近三十年来,日本的冷藏库技术,在各方面都取得了很大的进展,其中冷藏库的自动化是从1965年起才得到了发展,到了70年代中旬微型计算机被引入到冷藏界,最近OA化(OFFICE AUTOMMATION),FA化(FACTORY AUTOMATION)的普及是相当惊人的。当然在冷藏界,微机控制的主要目的是为了节能和省力。这是由于尽管对耗电较大的 I. Preface Great progress has been made in various aspects of Japan’s cold storage technology in the recent three decades, of which the automation of cold storage has only been developed since 1965. By the mid-1970s microcomputers were introduced into the cold storage Recently, OA (OFFICE AUTOMATION), FA (FACTORY AUTOMATION) popularity is quite amazing. Of course, in the refrigeration sector, the main purpose of microcomputer control is to save energy and effort. This is due to the greater power consumption
