CAS号:

性质:又称真空式冷冻机。冷冻设备的一类。通常借水的状态变化以获得低温,称做蒸汽喷射式汽化冷冻机。具有足够高压的蒸汽由发生器进入喷射器,膨胀而将压力降低到与蒸发器中的低压相等,因而具有较高速度,能将蒸发器中产生的蒸汽吸入并与之混合。这混合蒸汽在喷射器的扩大管中被压缩到等于冷凝器的压力,而在冷凝器中液化。冷凝后的水,部分经过膨胀阀进入蒸发器中进行汽化,从被冷冻物料吸取热量,另一部分则由泵送回发生器,优点是:(1)喷射泵结构简单,检修容易,造价低廉,且不直接用机械动力和电力;(2)用水作冷冻剂,价格低廉,容易取得,汽化热值高,无毒无危险性。主要缺点是要得到较低的温度,需要很低的压力,往往需用几个喷射泵串联使用。适用于制取+10~-10℃的低温,如制冰、空气调节和制药工业等方面。
