Moreover, even in normal working operation, the unit can generate very high temperature(may 

exceed 100°C) and very low (below -40°C) temperatures on compressor housing and tubing surfaces 
resulting  in  the  possibilities  of  severe  contact  burns.  Special  caution  must  be  taken  when  working 
around the unit

注意

     

真空环境

Caution

     Deep Vacuum

 

      

请勿在高真空条件下使用压缩机,这可能导致电器故障。对于制冷或空调系统,请不要用压缩机

抽真空。

 

Do  NOT  operate  compressors  in  deep  vacuum  conditions  as  this  can  cause  electrical  failure. 
Compressors should never be used to evacuate refrigeration or air conditioning systems

.

注意

     

电机保护

Caution

     Motor Protection

 

 

警告:不要往正在运行中的风机中插入任何物体。这样将导致严重的人员伤亡或设备损坏。

 

 

WARNING: Do not insert any object into operating fans. Ignoring this warning may result in 

personal injury and/or severe equipment damage and consequences

.

 

 

“精锐” 压缩冷凝机组使用涡旋压缩机,其带有内置过载保护装置,在压缩机过载的情况下,可自动断开

压缩机的电源,从而保证压缩机的安全。未经充分冷却,内置过载保护不会自动复位,时间可能需要几个小时。 

涡旋压缩机仅能一个方向运行。请参考安装和试运行说明,以确保压缩机正确运行。 

     “SLIM  POWER”  condensing  units  use  scroll  compressor  ,  which  are  fitted  with  inherent 

internal line break motor protection. After opening, the protector may not reset for several hours until 
the motor cools sufficiently.  

Scroll  compressors  can  only  run  in  one  direction.  Refer  to  Installation  and  Commissioning 
Instructions for details of how to identify if the compressor is running correctly.

原理

  

Purpose

 

“精锐”压缩冷凝机组,包括中温、低温,按照设计,冷量是由制冷剂在蒸发器中蒸发不断提供的,冷凝

机组向环境放出热量。 

冷凝机组应水平安装在室内/室外环境下,(细节部分请参照总体布置图),冷凝温度建议不高于 55℃,  

返回压缩机的吸气温度不大于 20℃(具体请参考样本数据)。 

机组不宜安装在有害、腐蚀或易燃的环境中。海洋性气候对设备是有腐蚀危害的,若必须安装在此环境下

请咨询百尔公司。 

“SLIM  POWER”  condensing  units  are  standard  OEM  products  of  Beijer  Ref  including 

“medium” and low temperature application ranges. They are designed for continuously supplying and 
receiving the refrigerant to and from the evaporator(s), and rejecting the heat extracted from the cold 
space to the surrounding atmosphere where the units are installed.  

 
“SLIM POWER” condensing units are intended for installing in a typical ventilated indoor or 

outdoor  environment  (Refer  to  the  General  Arrangement  Drawing  section  for  details)  with  the 
condensing  temperature  no  greater  than  55°C  and  compressor  return  vapour  temperature  no  greater 
than 20°C (Refer to catalogue).
