Ensure that the installation complies with
HACCP and/or relevant regulations for food
safety, and the end user’s preferences when
choosing copper, stainless steel or PVC
material for condensate drain lines. For low
temperature applications, proper insulation
and heating cable shall be provided to
prevent the drainpipe from freezing. Provide
a minimum 300mm per meter pitch to
condensate drain lines for proper drainage.
Drain lines should be at least as large as the
evaporator drain connection. All condensate
drain lines must be trapped to prevent
outdoor air and odours entering the
refrigerated room, and must never be
connected directly to the sewer system. All
traps must be located in a warm ambient to
prevent water from freezing. It is
recommended that the drain line be kept to a
minimum length within the refrigerated room.
请确认排水管的安装符合食品的 HACCP 及相
应的安全规范，材料可选择铜管，不锈钢管或
PVC 管，根据客户而定。对低温应用工况，
需提供保温及加热丝以防止排水管结冰。推荐
每
1 米 300mm 的坡度正确安装排水管。排水
管的尺寸至少和冷风机的积水盘接头一样。所
有的凝结水排水管必须要安装
U
型弯以防止
外界空气及异味进入冷库，绝对禁止直接和排
污系统相连。所有
U
型弯置于温暖的环境以
防止结冰。建议排水管在冷库内的长度要尽可
能短。
To obtain the best performance of the
evaporator, the distributor body shall be
mounted vertically to ensure refrigerant liquid
being distributed evenly to all the circuits.
For each unit through the whole range of
BOHN Heavy Duty Evaporators, a carefully
selected Sporlan-type orifice will be factory-
fitted in the distributor based on your request
of refrigerant type before delivering the
completed unit to your preferred site.
为保证冷风机达到最佳的制冷效果，分液器必
须竖直安装，确保制冷剂均匀地分配到各个制
冷回路中。
对于
BOHN
工业型冷风机中每一个型号，在
发往客户指定的地点前，根据客户所采用的制
冷剂，我司已在工厂安装了和分液器配套的
Sporlan
孔板。
For best performance, the TX valve should
be installed as close to the distributor as
possible.
Locate the TX valve sensor bulb on the
horizontal section of suction line and close to
the suction header. For a satisfactory TX
valve operation, good thermal contact
between the sensor bulb and the suction line
is essential. Follow TX valve manufacturers
recommendations when positioning TX valve
and sensor bulb. Incorrect installation may
result in poor evaporator performance.
The external equalisation line should be used
to link the TX valve external equalisation port
and the suction line, near the suction header.
A ¼” tube brazed to the suction line is
supplied for that purpose.
为了达到最佳的制冷效果，热力膨胀阀应尽可
能安装在离分液器近的位置。
将热力膨胀阀的感温包放置在吸气管的水平位
置，并且离吸气集管比较近的位置。为了达到
良好的运行效果，必须保证感温包和吸气管之
间达到良好的热接触。热力膨胀阀及感温包的
放置请遵循生产厂家的指示。不正确的安装会
导致制冷效果变差。
外平衡管用于连接热力膨胀阀的外平衡口和吸
气集管附近的吸气管。连接到吸气管的
1/4
英
寸铜管就是所说的外平衡管。
