上海市通用机械技术研究所在华东化工学院和上海恒温控制器厂协助下,研制成功制冷系统用氟利昂 YC 型潮汽——液体指示器并通过技术鉴定。潮汽——液体指示器是国外七十年代开始广泛应用在制冷设备中的一个新型元件,它由在玻璃窥镜中放置能随含水量多少而变色的指示片所组成,把它安装在膨胀阀前的液体管路中不仅可以观察氟利昂工质流动情况,而且还可以检查工质中含水量的变化,是制冷设备维护保养的一个重要检测工具,该所将小批量投入生产,以满足用户单位的需要。
Shanghai General Machinery Institute of Technology in East China Institute of Chemical and Shanghai Thermostat controller plant with the assistance of the successful development of refrigeration systems with Freon YC tidal vapor - liquid indicator and through technical appraisal. Tidal vapor - liquid indicator is the seventies abroad began to widely used in refrigeration equipment, a new element, which consists of glass placed in the mirror with the amount of water can change the color of the indicator sheet, it is installed in the expansion The liquid pipeline in front of the valve can not only observe the flow of Freon, but also check the change of water content in the working fluid. It is an important test tool for the maintenance of refrigeration equipment. It put small quantities into production to satisfy users Unit needs.
