冷冻板制冷技术在铁路保温车上应用的研究,自1979年8月至1980年2月间完成了第一阶段的工作,对冷冻板冷藏汽车进行了运行试验和试验室静止性能试验。武昌车辆工厂又根据铁道部(80)科技运电字78号文件,关于装配冷冻板制冷的保温车设计任务书的通知及其附文——技术条件,进行了B_(12)型保温车改装冷冻板的结构方案设计。部科技局于1980年6月2～3日在武昌车辆工厂主持召开了方案讨论会。参加讨论会的有上海市食品进出口公司、上海、长沙铁道学院、上海铁路局、武昌工厂、四方车辆研究所等单位。
The research on the application of the refrigeration plate refrigeration technology in the railway insulation car has completed the first phase of work from August 1979 to February 1980 and carried out the running test and the static performance test of the refrigerator on the frozen plate refrigeration truck. Wuchang Vehicle Factory also carried out the modification of the B 12 thermostat according to the document No 78 of the Ministry of Railways (80) Technology Transcript No. 78, the notice on the design task of the insulation truck equipped with the refrigeration plate refrigeration and its attached document - technical conditions Structure Design of Freezing Plate. Ministry of Science and Technology Bureau in 1980 June 2 ~ 3 in Wuchang vehicle factory chaired a program seminar. Participants in the seminar are Shanghai Food Import & Export Corporation, Shanghai Railway Institute, Changsha Railway Institute, Shanghai Railway Bureau, Wuchang Factory, Sifang Vehicle Research Institute and other units.
