蒸发式冷凝器在合成氨冷冻系统中的应用

Use of Evaporative Condenser in Ammonia Refrigeration System

根据蒸发式冷凝器工作原理和技术特性,制定出冰机冷凝器的改造方案。介绍了蒸发式冷凝器的选型参数、安装及运行效果。使用蒸发式冷凝器后,弛放气中氨浓度由原5.0 g/m3下降至0.5 g/m3,年节约电费76万元以上、节约水费30万元。

A plan for revamping the refrigerator condenser is laid down on the basis of the working principle and technological performance of the evaporative condenser. The model selection parameters of the evaporative condenser and the results of its installation and operation are given. After its use the ammonia concentration in the purge gas decreases from 5.0 g/m^3 to 0.5 g/m^3, with an annual saving in power of over 760 000 yuan and a water saving of 300 000 yuan.
