一、概述上海第一冷冻机厂生产的各种冷冻机配套用的冷凝器均为立式氨冷凝器,随着生产的发展,冷凝器的产量逐年增加,但立式冷凝器的传热效率比较差,金属材料消耗多,制造工时也较多,用户普遍反映实际使用达不到设计要求,使用单位常常除配套的冷凝器之外,另外增加订货立式冷凝器,以加大冷凝面积,降低冷凝压力。 First, an overview Shanghai first freezer factory production of various freezer supporting the condenser are vertical ammonia condenser, with the development of production, the condenser output increased year by year, but the vertical condenser heat transfer efficiency Relatively poor consumption of metal materials, manufacturing man-hours are also more users generally reflect the actual use of less than the design requirements, the use of units often in addition to supporting the condenser, the addition of additional vertical condenser order to increase the condensation area, Reduce condensing pressure.
