摘要
随着国家对节能产品的提倡,满液式机组也越来越受到欢迎。满液式机组与普通冷水机组的区别就在于蒸发器采用了满液式蒸发器,而普通冷水机组采用干式蒸发器。满液式蒸发器与干式蒸发器二者的明显区别在于制冷剂流程的不同,满液式蒸发器制冷剂走壳程,制冷剂从壳体下部进入,在传热管外流动并受热沸腾,蒸汽从壳体上部排出。干式蒸发器中制冷剂走管程,即制冷剂从端盖下部进入传热管束,在管内流动受热蒸发,蒸汽从端盖上部排出。
Flooded chiller is being more and more popular with our government′s promotion of energy saving products.The major difference between flooded chiller and normal chiller is their evaporator installed inside,flooded evaporator was installed in flooded chiller while DX evaporator in normal chiller.The obvious difference of these two kinds of chillers is their refrigeration passes.In the flooded chiller,refrigerant runs into shell from the bottom,then flows outside of heat exchanging piping,being heated and boiled,turns into vapor and being discharged from the top of shell.In DX evaporator,refrigerant runs inside tubes.It enters tube bundles from the bottom of end cover,flows inside the tubes,being heated and evaporates,then being discharged from top of end cover.
