In the article, a simple and high efficient, once-through ammonia refrigeration system with flooded evaporator, is presented to explore the possibility of replacement of CFCs and HCFCs, ammonia. 本文在分析氨的热力性质的基础上,讨论一种简明、高效的氨制冷系统&带满液式蒸发器的直接膨胀供液制冷系统,来替代CFCs和HCFCs制冷剂的可能性。
Reason Analysis on Pipe Explosion of Ammonia Evaporator 氨蒸发器列管爆裂的原因分析
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. 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。
The ammonia refrigeration evaporator was used as an example to calculate the effect of temperature difference of heat transfer oncost, and analyse the significance of optimal design. 以氨制冷蒸发器为例,计算、分析了传热温差对费用的影响及其优化设计的意义。
