In general, Beijer Ref recommends 60°C condensing temperature as the maximum operating
condition for “SLIM POWER” condensing units.
When using the HP controller, the type of refrigerant and the max environment temperature
would be taken into account.
百尔公司还配备了低压开关作为安全保护装置。根据应用场合、压缩机型号的不同, 低压开关的设置应考
虑以下几点：
低压开关的”切断”温度值应低于最小设计饱和吸气温度 3-5K
低压开关的”切断”值应该在正压区.
当机组安装在温度较低的环境下，低压开关的”切断”压力值应低于其安装在此环境下温度对应的饱和
压力值
Beijer Ref also recommends the LP switch to be used as a safety protection device. Depending
on the application and compressor, LP cut-in and differential points should be set with the following
considerations
：
Set the cut-out points at 3–5 K below the respective minimum design saturated suction
temperatures (Refer to the Standard Design Conditions section for saturated suction
temperature ranges).
The cut-out pressure shall be in the positive pressure region
.
When the unit is installed in a cold ambient, the cut-out pressure shall be lower than the
pressure corresponding to the ambient temperature.

警告
自动重启
&
电机保护
Warning
Reset & Motor Protect
压缩机过载时，过载保护断开电路，使压缩机停止运行，负载恢复正常后，不需要预先警告就会自动复位
或运行。
When compressor over-load, the overload protection circuit disconnected, the compressor stops
running, after load is returned to normal, the compressor will automatically reset and may operate
without warning.
2.1.7
压缩机高温
Compressor High Temperature
系统出现故障时，压缩机的壳体和排气管的温度最高可达
150°C
，这样的高温可能对线路或其他材料造成损
坏，所以不可直接接触壳体和排气管。
Compressor housing and discharge line temperatures may reach 150°C due to failure of system
components. Wiring and other materials which could be damaged by these temperatures should not
come into contact with the housing or discharge line.
2.1.8
高真空
Deep Vacuum
不要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，不能用压缩机抽真空。
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
.
2.1.9
润滑油
Lubrication
“精锐”冷凝机组，使用的润滑油是聚脂油（POE）或矿物油。
“SLIM POWER” compressors use Polyester (POE) oil or mineral oil.
