氟用桶泵机组

Fluorine barrel type pump system

高效节能的氟泵供液系统是利用泵的机械作用,向蒸发器输送低温制冷剂液体的制冷系统。节流后的低温制冷剂液体,首先进入具有一定贮液容积和一定气液分离容积的低压循环桶中,再用氟泵把数倍于蒸发量的低温液体输送到各库房蒸发器中。大部分液体在蒸发器吸热汽化,其余液体随汽体经回气管返回低压循环桶。经气液分离后,汽体被制冷压缩机吸走,分离下来的液体和相当于蒸发量的新补充液体,又被氟泵输送到蒸发器进行再循环。

High efficiency energy saving fluorine barrel type pump system is a refrigeration system utilizes pumpprinciple, running by delivering liquid format refrigerant into evaporator. The throttled low temperaturerefrigerant liquid, firstly enters a low pressure cycling barrel which has certain liquid storage space and gas-

liquid separation space, then uses a fluorine pump pumping the low temperature liquid refrigerant whichhas several times larger volume than evaporation amount, into the evaporators in each cold room. Mostof the liquid in the evaporator absorbs heat and turned into gas, the rest of the liquid goes back to lowpressure circulation barrel through return pipe along with gas, after gas-liquid separation, the gas will betaken away by compressor, the liquid left together with newly added liquid which has a volume equivalentto refrigerant amount, are pumped back to evaporator to complete the recycling.

主要优点

Main advantages

● 蒸发器具有较高的蒸发换热效率,冷却效果好。制冷剂循环量数倍于蒸发器的蒸发量使蒸发器有着充分的润湿表面,可以发挥蒸发器全部蒸发面积的传热效能;制冷剂在蒸发器内呈环流流动状态,气体在中心部位流动,从而强化了制冷剂和管壁面的换热条件;而且,由于大量制冷剂的冲刷,蒸发器管壁不易形成油膜,其底部也不易积存油污,从而使管壁传热系数得以提高。所以,同样蒸发面积的蒸发器,氟泵供液的冷却效果比直接膨胀供液提高25-30%左右。

● 能够保证长距离供液。利用泵的机械作用,可以克服系统中的部分阻力损失,实现长距离供液。

● 系统操作简单可靠,便于集中控制和实现自动化,制冷压缩机的运行工况得以改善。氟泵供液制冷系统,在库房热负荷无大波动,氟桶液面较稳定的情况下,就能维持氟泵的正常运行,而不需要经常性的调节工作,同时让制冷装置自动化变得更加容易。

● 热氟融霜操作简便。氟泵供液制冷装置中,融霜时把蒸发器内的剩余液体直接排至低压循环桶中,融霜完毕开启氟泵即可恢复蒸发器的供液,恢复正常库温的速度快,操作方便。上述融霜方式利用其他制冷房间的冷凝热源为融霜房间提供冷源,经济节能(相对于电热融霜节能80%以上)。

卧式桶泵组合装置是食品速冻库为满足行业需求研发的大型制冷组合装置,卧式桶泵组合装置将卧式低压循环桶和氟泵组装在同一钢架上,工艺管路、阀门、自控元件均已配备齐全,构成桶泵一体化供冷装置。

具有自动供液、液位显示、超高液位报警及过热度控制双重保护、氟泵自动报警等功能。

● Using fluorine barrel pump system, the evaporator has a higher evaporation efficiency, the coolingperformance is good. The refrigerant recycling amount is always several times larger than the evaporationamount in evaporator, this ensures a fully wet surface inside the evaporator, so that the the evaporator’sability can all play out. Refrigerant circulates inside the evaporator along the pipe wall while the gas flowsin the pipe center, this guarantees an excellent heat exchange situation between refrigerant and pipesurface. Moreover, because of being largely scoured by the refrigerant, it isn’t likely to form an oil film,the bottom as well will not easy to accumulate oil dirt, in this case the pipe wall can remain a good heatexchange performance. In conclusion, using same evaporator, fluorine barrel pump feeding has a 25~30%better result than direct evaporating.

● It ensures long enough distance liquid feeding. By using the pumping principle, it can overcome the

resistance loss in the system, to guarantee a long distance feeding.

The system is simple but reliable, it’s convenient for centralized control and automation, the operating condition of the compressor can be improved. Fluorine pump feeding system can maintain its function without frequentlyadjustment as long as barrel has relatively stable level of liquid and the heat load of the room doesn’t have largefluctuation, this will make the automation of the refrigeration more easily.

● Hot fluorine defrosting is easy to operate. In the fluorine pump feeding system, when defrosting, it directly leadthe left liquid in the evaporator into low pressure cycling barrel, after defrosting finished, turn on the pump then the

evaporator liquid feeding will be carried on. It returns the cold room temperature more faster, very easy to operate.The above mentioned defrosting uses the condensing heat source from other cold room as its heat source, it’s moreeconomic and energy saving (saves 80% more compared with electric defrosting )

● Horizontal barrel pump system is a combination of large refrigeration unit developed by us in order to meet industry

need. This system unites the horizontal low pressure cycling barrel and fluorine pump onto the same steel frame,together with process piping, valves and controlled components, completes the barrel-pump integrated refrigerationsystem. It has auto feeding, liquid level display, fluorine barrel auto alarming system and double protection includingliquid level over filled alarm and over heated control, etc.
