Always take care to ensure a proper weight balance before lifting and moving unit.

 

 

2.1.2 

  

机组的拆箱

Unpacking of Unit

 

拆箱后,检查机组及其他备件是否有任何损坏,如发现任何损坏,请及时联系百尔。

 

When unpacking, inspect for any damage to packing material or the unit itself which may affect 

the unit’s performance. If any such damage is evident, please contact your local Beijer Ref branch.

 

 

2.1.3 

  

机组的放置与固定

   

Installation Location (Refer to the General Arrangement Drawing section)

 

如果机组放置在靠近墙壁的场所或者密闭通道内,需要确保机组能获得足够的风量,以供风量的的畅通及机

组的维修。机组必须牢固地安装在坚固水平的地面上,以防止它掉下或翻倒。 

尤其是要保证机组有一个通畅的环境,以阻止冷凝机组排放出的热空气回流。 

压缩机冷凝机组须用相应的地脚螺栓水平固定在基础上。

 

机组的供液管路均装有视液镜,在机组运行时,应留有足够的空间来观察视液镜。 

If  the  unit  is  to  be  located  in  close  proximity  to  a  wall  or  similar  obstruction,  the  minimum 

distance from the coil face to the obstruction shall comply with the general arrangement drawing. The 
unit shall be mounted on a horizontal plane surface.

 

   It  is  particularly  important  for  the  units  to  allow  sufficient  unobstructed  air-discharge  space  in 

front of the unit to prevent warm air recirculation to the condenser

 

   

Condensing Unit should be properly installed on horizontal base with corresponding foot bolts.

 

  The liquid  sight  glass is  located inside the unit. Allow sufficient  space around the access  panels 
for opening the panels

 

2.1.4 

 

系统充注

System Holding Charge

 

系统在出厂时均充注干燥空气或氮气。 

如果收货验收时发现系统未经充压,请及时联系百尔制冷公司。 
将系统预先充注的气体以适当的方式排出。在制冷系统中选择合适的排气位置。 

机组在试运行之前需将系统中的压力抽空至 200 微米以下。 

The system as supplied is pressurised at the factory with Dry Air or Nitrogen gas. 
   If the system is not pressurised on delivery, please contact your Beijer Ref branch.  
  Care  must  be  taken  to  release  the  pressure  before  attempting  to  gain  access  to  any  part  of    the 
refrigeration system. 
  The unit should be evacuated to a pressure of 200 microns (μmHg) prior to commissioning.

 

 

2.1.5 

压力设置

  

Pressure Settings

 

风冷冷凝机组的最大运行压力为

29bar

,这主要取决与压力容器(储液器)的限制。因此卸压装置的压力应小

29bar

。压力开关的设置,如高压侧压力必须小于

26bar

 

建议

卸压装置设置应不大于

0.9

倍最高工作压

力。“精锐”风冷机组最大设计的冷凝温度为

60

℃。当使用

HP

控制设备时,必须考虑到使用制冷剂的类型以

及环境的最高温度。

 

“SLIM  POWER”  condensing  units  have  a  maximum  operating  pressure  of  29  Bar(g) 
determined  on  pressure  vessels  (such  as  liquid  receivers).  Thus  any  pressure  relief  device 
setting must be 29 bar(g) or lower.  
Pressure limiting device settings such as the HP control  must be  26 Bar(g) or lower. Adviced 
that  the  pressure  limiting  device  setting  is  no  greater  than  0.9  times  the  maximum  operating 
pressure
