一、前言螺旋板式氨冷凝器,于1970年—1972年在上海第一冷冻机厂试验室内进行过测试,取得了较好效果。为了考核在生产单位的长期实际使用情况,为今后正式投产积累资料,于1971年6月在上海吴径砖瓦厂四车间内装置了一具36米~2螺旋板式氨冷凝器,供该车间4AJ-15盐水制冷系统使用。 1973年11月30日由上海第一冷冻机厂召集了由有关工厂、高等院校、科研设计等十四个单位参加的“关于螺旋板式氨冷凝器、蒸发器 I. Introduction Spiral plate ammonia condenser, from 1970 to 1972 in the first Shanghai Refrigeration Factory test room has been tested and achieved good results. In order to assess the long-term actual use of the production units and to accumulate data for the official production in the future, a 36m ~ 2 spiral plate ammonia condenser was installed in the fourth workshop of Shanghai Wujing Brick and Tile Factory in June 1971 for the workshop 4AJ-15 brine cooling system. November 30, 1973 by the Shanghai First Freezing Factory convened by the relevant factories, institutions of higher learning, scientific research and design fourteen units attended the "spiral plate ammonia condenser, evaporator
