Refrigeration piping work shall be carried out professionally by qualified refrigeration mechanics in
accordance with applicable national and local regulations and in conformance with good engineering
practices required for the proper operation of the refrigeration system.
百尔生产的压缩冷凝机组有较高的洁净度和干燥度，并且系统内部充注了干空气或氮气，可以防止氧化和
湿气及异物的进入。 管道在安装时应格外小心，减小管道安装的时间可以防止湿气或异物的进入。
内部相连的制冷管道的大小不必与机组的出口管道大小一致。 管道尺寸的选择/计算是基于确保最小制冷
剂压降和有效回油最低制冷剂流速。百尔公司可提供相应的管道尺寸计算的技术支持。
水平吸气管与机组连接的时候应有适当的坡度，使油因为重力而自由返回压缩机。1：100 的坡度是比较合
适的。竖直段管道必须使用回油湾及双立管。吸气管道应有保温措施，减小过热影响。
如果在安装时有任何疑问，请向当地的销售代表咨询。
All Centurion condensing units manufactured by Beijer Ref are supplied clean and internally
charged with dry air or nitrogen to prevent oxidation and ingress of moisture or foreign matter. Care
shall be taken during installation of the piping to prevent entrance of foreign matter or moisture by
minimizing the time that the piping is uncapped.
The interconnecting refrigeration pipe size is not necessarily the same size as the outlet on the
unit. The pipe sizes shall be selected/calculated based on the best compromise of minimizing
refrigerant pressure drop and refrigerant velocity to ensure efficient oil return.
Horizontal suction lines shall slope towards to the units to allow the oil return freely to the
compressor by gravity. A 1:100 slope is considered sufficient. The use of oil trap and double risers
may be necessary on vertical sections. Suction line piping shall be insulated to minimize the
superheat effect to the vapour.
If in doubt during the installation, please consult with your local sales representatives
and/or application engineers from Beijer Ref for technical support.
2.3 压缩机启动 Compressor Starting
对于较大型的压缩机启动时产生的瞬间起动电流要格外小心。
Care should be taken to establish starting requirements for the larger compressors due to high in-
rush current.
2.4 冷凝风扇控制 Condenser Fan Controller
“精锐”冷凝机组可选配冷凝风扇控制器。
使用R404A制冷剂时，推荐设定值为:单风扇11 Bar(g)，双风扇11 Bar(g) 和14Bar(g)。
R22制冷剂时，推荐设定值为:单风扇9 Bar(g)，双风扇9 Bar(g) 和12Bar(g)。

2.5 常规调试&拆卸指南 General Commissioning & Decommissioning Guide
2.5.1 警告——调试 Warning –Commissioning
制冷系统的调试应由专业的制冷技工完成，其必须具备良好正确操作制冷系统的工程实践能力。
Refrigeration system commissioning shall be carried out professionally by qualified refrigeration
mechanics in conformance with good engineering practices required for the proper operation of the
refrigeration system.
在所有安装及电气连接完成之后，整个制冷系统必须进行泄漏测试。如果系统没有泄漏，制冷系统的管路
需要保温，室外环境下保温材料应具有防紫外线功能。
在充注制冷剂之前，制冷系统需要由一台良好的高真空泵来抽气，将其连接在高压侧和低压侧的检修阀或检
修口上。
充注任何制冷剂时，具备良好的工程实践能力是必要的。特别是混合（共沸）制冷剂，如 R404A，必须遵
守适当的程序。
抽气至合适的压力，先充注 60%~80%的制冷剂量，以液态的形式充注到储液器，压缩机未运行，当系统压
力稳定后，启动压缩机，向吸气管缓慢充注剩余的制冷剂，以液态的形式通过仪表节流阀，使其在进入压缩机
之前蒸发，如果系统中有汽分, 在汽分前充注。
在系统初始运行后，从视液镜中查看制冷剂充注情况，如果制冷剂量不够，从吸气管添加，若制冷剂过多，
将多余的释放到回收桶中。
After all installation and electrical work is completed, the entire refrigeration system must be leak
tested. After satisfactory testing of the refrigeration system, then refrigeration lines shall be
insulated as necessary. The insulation located in “SLIM POWER” environments shall be protected
from UV exposure.
Before charging the refrigerant, the entire refrigeration system shall be evacuated by connecting a
good, high vacuum pump to both the high-pressure side and low-pressure side service valves or
ports.
It is important to apply good engineering practice when charging any refrigerant, but in particular
blended ( zeotropic ) refrigerant, such as R404A, require proper procedures to be observed:
•Initially charge 60 to 80% of the expected refrigerant charge in liquid form into the liquid receiver
with the compressor not running (after evacuation to the correct pressure).
•When the system pressure has stabilized, start the compressor & slowly charge the remaining
refrigerant quantity into the suction line in liquid form through a gauge manifold or a throttling valve
to allow it to vaporize before entering the compressor. If the system is fitted with an accumulator, it
is preferable to charge upstream of the accumulator.
•After initial running of the system, check the refrigerant charge condition at the sight glass and add
any required refrigerant in the suction side as noted above, or remove excess refrigerant into an
approved reclaim cylinder

and forced out of fan motor side.
If fitted, ensure that the crankcase heater has been energised for a minimum 12 hours before
initial start-up and / or after prolonged shutdown periods.
After the successful start up of the system, check:
•Current draw and voltage levels.
•Suction superheat settings and discharge temperatures.
•Abnormal refrigeration piping vibrations.
•Oil level and refrigerant charge.
2.5.2 警告—拆卸 Warning—Decommissioning
对于机组从安装的地方拆除，需要专业技术人员按照一定的程序来进行。假如不按步骤进行的话可能
引起机组失火或爆炸，这将导致人员的伤亡，财产损失。不允许把制冷剂直接排放到大气中。
In order to remove the unit from its mounting place, the following procedures need to be carried out
professionally by qualified personnel. Failure to do so may result in personal injury or death, property
damage by fire or explosion. Discharge of refrigerant to atmosphere is illegal and may result in heavy
fines by relevant regulatory authorities.
要把所有的制冷剂泵到储液器或适当的容器中（如回收桶），然后关闭相关阀门。所有不能重新使用的制
冷剂必须回收或者销毁；
切断电源，拆除所有现场的电线以及相关设备，最后拆除接地线；
由于机组和外界环境存在压差，在拆除制冷剂管道时要特别小心。系统的润滑油中存有少量的制冷剂，系
统中压力的升高使制冷剂不断的沸腾和汽化这对人会造成潜在的危害；
切割并密封液管和吸气管的连接处；
把机组从安装位置上搬走，需要适当的搬运设备。
Pump down the entire refrigerant charge into the liquid receiver or appropriate container such as
reclaim cylinder, and shut related valves. All reclaimed refrigerant that is not re-used must be
taken to an approved refrigerant recycling or destruction facility. Beijer Ref Branches will
accept the used refrigerant.
Disconnect the power supply. Remove all necessary field electrical wiring and related
components, leaving the earth wire to the last.
Care must be taken when disconnecting the refrigeration piping because of unbalanced pressure
between the unit and ambient. There may be a small amount of refrigerant trapped in the oil, the
