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

例。制冷剂都不能直接排放到大气中。使用过的制冷剂要进行回收。
Beijer Ref is dedicated to providing safe products and protecting the environment by complying
with all applicable national laws and regulations governing environmental protection. New and
used refrigerants cannot be vented into atmosphere. Reclaim all used refrigerants. Ensure your
refrigerant handling procedure complies with the relevant regulations.
