摘要
介绍了一种开启式螺杆氨盐水机组,采用PID控制的电子膨胀阀直接供液,蒸发器和冷凝器均采用半焊式板式换热器。并生产了一台样机进行测试,最终取得了很好的效果。
A new type ammonia brine unit was introduced in this paper, which use electronic expansion valves to supply liquid and use semi-laser welding plate-and-frame heat exchangers as condenser and evaporator. A prototype was made and tested. Test result was acceptable.
