电子工业部于六十年代初进口了十套苏联12—Э型蒸汽喷射式制冷机。汽源为热电厂汽轮机的撒汽。这十套设备至今已使用了二十多年。12—Э型蒸汽喷射式制冷机采用卧式设备(见图1),冷凝器为表面式,以便回收凝结水。蒸发器为混合式。主喷射器垂直布置。该机组配有整套自控仪表。其主要设计参数如 In the early 1960s, the Ministry of Electronics Industry imported ten sets of Soviet 12-Э type steam jet chillers. Gas source for the steam turbine steam plant steam. These ten devices have been used for more than twenty years. 12-Э type steam jet refrigerator with horizontal equipment (see Figure 1), the condenser surface type in order to recover the condensate. Evaporator is hybrid. Main injector vertical arrangement. The unit is equipped with a complete set of automatic control instrument. Its main design parameters such as
