由机械工业部下达给通用机械技术设计成套公司的组合冷库研制科研任务,分二阶段进行。第一阶段工作由通用机械成套公司与大连冷冻机厂和上海制冷设备厂合作研制35m~3和20m~3低温用组合冷库各一台于84年9月通过了技术鉴定。第二阶段工作要求在第一阶段的基础上,把产品技术水平和质量再提高一步,使配套的冷风机、制冷压缩机和库板等有较大的改进。由通用机械成套公司负责设计,烟台冷冻机厂负责制造ZL—26m~3的组合冷库。
By the Ministry of Machinery Industry issued to the general machinery technology design company portfolio cold storage research and development tasks, in two stages. The first phase of the work by the General Machinery Company and the Dalian Refrigeration Factory and Shanghai Refrigeration Equipment Factory cooperation in the development of 35m ~ 3 and 20m ~ 3 low temperature with a combination of cold storage in September 84 passed the technical appraisal. The second phase of the work requires that in the first stage, based on the technical level and quality of products to take one step further, so that supporting the chiller, refrigeration compressor and the library board and other major improvements. By the General Machinery company responsible for the design, Yantai freezer factory is responsible for manufacturing ZL-26m ~ 3 combination of cold storage.
