Installation Instructions 安装说明
a) Lifting of Unit a）设备的吊装
b) Unpacking of Unit b）包装的拆除
c) Mounting the Unit c）设备的安装
The weight of the unit ranges from 70 to
350kg. Always use the appropriate
mechanical handling equipment to lift the unit
into
p
lace.
设备的重量在 70~350Kg 之间，用合适的设备
吊起到适当的位置。
When unpacking, check 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
Heatcraft branch.
拆包装的时候，检查设备和包装材料是否受
损，任何受损可能会影响运行效果。如果发现
有明显的受损部位，请您联系西克各地办事
处。
These evaporators can be mounted with
threaded rods and bolts. As a general rule,
the single 5/16” rod, and bolts and washers
can lift the weight up to 110kg (250 lb), 3/8”
for up to 270kg (600 lb). However it is the
installer’s responsibility to ensure the
evaporators mounted securely and
professionally.
To comply with HACCP and/or relevant
regulations for food safety, the area above
the evaporator must be sealed or exposed in
such a way to facilitate hand cleaning without
the use of tools. So depending on the end
user’s preference, the evaporators can be
installed either,
•Using threaded rod and allow sufficient
space between the top of the evaporator
and the ceiling for cleaning, or
•Flush mount the evaporator to the ceiling,
seal the gap between the top and the ceiling
with food benign sealant to prevent
accumulation of any foreign matter.
All evaporators shall be mounted
professionally and levelled properly so that
condensate drains from the evaporator
efficiently. Adequate support must be
provided to hold the weight of the evaporator
plus the weight of the refrigerant and any
frost that may accumulate on the coil surface.
The use of weight lifting equipment is highly
recommended whenever possible.
冷风机可以用螺栓和螺母固定。一般来说，单
个M8 的螺栓和螺母能承受重达 110Kg(250lb)
的重量，M10 的能承受重达 270Kg(600lb)的
重量。尽管是这样，但安装人员有责任确保蒸
发器安全的、专业的安装在指定位置。
为了遵守 HACCP 和/或有关的食品安全标
准，蒸发器的上面必须密封，或者不密封的话
请留出一定的空间方便手工清洗。以上两种方
式根据终端用户的实际需要而定。
•用螺栓固定蒸发器，并在顶板到天花板之
间留有足够的空间以便于清洗。
•将冷风机对齐安装在天花板上，采用亲食
品的密封材料密封天花板和冷风机顶部间的空
隙。
冷风机安装要得当，位置要适中，以保证凝结
水能有效地排出冷风机。支撑必须有足够的能
力承受冷风机自身的重量，冲注的制冷剂重量
及盘管表面寄居的霜的重量. 可能的话推荐使
用起重设备来吊装。

e) Refrigerant Distributor and Nozzle e）制冷剂分液器及节流环
f) TX Valve, Sensor Bulb and External Equalisation Line
f）热力膨胀阀, 感温包及外平衡管
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。

g)Refrigeration Piping g)制冷管路
Note: With modern high quality TX valves,
refrigerant leakage through the equalisation
line is at a minimum and the TX valve
operation is not affected. Thus the external
equalisation connection could be made either
upstream or downstream of the sensor bulb
注意：目前热力膨胀阀的质量比较好，外平衡
管上很少会出现制冷剂泄漏，热力膨胀阀的运
行不受影响。 因此，外平衡管连接位置既可
以在感温包前，也可以在感温包后。
Refrigeration piping work shall be carried out
professionally by qualified refrigeration
mechanics in accordance with applicable
national and local regulations and in
conformance with good engineering
practices required for the proper operation of
the refrigeration system
制冷管路的设计，安装必须由专业的制冷技工
依照国家和当地的规范，同时符合良好的制冷
工程运行实际。
All the evaporators supplied by Heatcraft
Wuxi are supplied clean and internally
charged with dry nitrogen to prevent
oxidation and ingress of moisture or foreign
matter. Care shall be taken during installation
of the piping to prevent entrance of foreign
matter or moisture by minimising the time
that the piping is uncapped.
The interconnecting refrigeration pipe size is
not necessarily the same size as the outlet
on the unit. The pipe sizes shall be
selected/calculated based on the best
compromise of minimizing refrigerant
pressure drop and refrigerant velocity to
ensure efficient oil return. Heatcraft can
provide a software program to assist in the
calculation of pipe sizes.
Horizontal suction lines shall slope away
from the evaporators to allow the oil return
freely to the compressor by gravity. A 1:100
slope is considered sufficient. It is a good
engineering practice to fit an oil trap when
the suction line rises above the evaporator.
If in doubt during the installation, please
consult with your local sales representatives
and/or application engineers from Heatcraft
Australia for technical support.
西克提供的所有冷风机都是干净的，并且内部
预先充注有干燥氮气以防止氧化及湿气和外界
杂质进入。在安装时，尽量减小接管暴露在空
气中的时间，以防止外界杂质和湿气的进入。
制冷连接管路不一定要和冷风机的出口管路一
致，管路尺寸的选择和计算应基于最小压降和
流速衰减的原则。西克可提供管路计算软件。
水平吸气管需以一定的倾斜度离开冷风机，确
保冷冻油由重力作用回到压缩机。1:100 的斜
率是足够的。当吸气管高于冷风机时，最好安
装回油弯。
如果在安装过程中有疑问，请咨询我们当地的
销售代表或应用工程师。

Vacuum must be maintained sufficiently so
as to minimise the occurrence of leaks when
the system is charged. Refrigerant must not
be charged into a system with known leaks.
Should vacuum not be maintained, check for
leaks with Nitrogen gas at a suitable
pressure prior to charging.
Installing a liquid line drier and a sight glass
in a refrigeration system is sound
engineering practice. The liquid line drier will
ensure all refrigerant supplied to the
refrigeration system is clean and dry. The
sight glass is a useful device to ensure
sufficient refrigerant is supplied to the
refrigeration system.
Refrigerant charging shall be in liquid form at
the high-pressure side of the system such as
condenser or liquid receiver. If the refrigerant
charging must be carried out through the
suction side of the compressor, charge in
vapour form only.
系统必须维持足够的真空度，这样在充注制冷
剂时不会出现泄漏现象。如果系统已有泄漏，
决不允许再充注制冷剂。如果系统不能保持真
空状态，那么在充注制冷剂前，用氮气在一定
压力下检漏。
制冷系统中安装液路干燥器和视液镜是比较好
的工程应用。液路干燥器可以确保系统中的制
冷剂是干净及干燥的。视液镜用来检查系统中
是否有足够的制冷剂。
采用液态制冷剂进行充注，一般在系统的高压
侧，比如在冷凝器或储液器。如果必须在压缩
机的吸气侧进行充注，必须以气态的方式充
注。
In order to maximise efficiency and airflow,
the following advisory defrost data has been
compiled. Defrost data is minimum number of
defrosts required per 24 hrs for average
room loads.
为了能使客户在使用我公司蒸发器时得到最高
的效率和最大的风量，建议根据以下除霜参数
进行除霜。
Double-check all field wiring connections and
factory terminals. Factory connections can
vibrate loose during shipment. Ensure
correct fan motor rotation, airflow is induced
from coil side and forced out of fan motor
side.
Check the room thermostat for normal
operation and adjust if necessary.
由于运输可能导致工厂接线松动，请再次确认
出厂前的接线及现场的接线。检查风扇马达的
运转方向是否正确，气流是否是从盘管处吸
入，从风机侧排出。
检查库房的温控器是否运行正常，有必要时可
对参数进行调整。

a) Defrost Termination Requirements a) 除霜终止要求
Each column represents a 3-hour period
during the day. An X indicates the hour that a
defrost should commence. “Heavy Load”
represents the nominal ‘working period’ of
each da
y
.
每列代表了每天时段中的 3个小时。X显示了
除霜应该开始的时间。"重负荷"显示的是通常
意义上每天的“工作时段”。
温度终止—温度终止的设定主要根据除霜的频
率和结霜的状况，另外还取决于温度传感器/
温度开关的位置。如果使用的是电子除霜控制
器，对于每个安装环境下的冷风机，其温度终
止的设定点必须单独确定，设定点应不低于
12℃切断。温度传感器的位置应根据各个不
同的安装环境进行优化摆放。将传感器放置于
盘管上时通常需要更高的设置点，一般为 20
℃或者更高。
压力终止—可采用多种方式用于除霜。不论采
用何种方式，必须注意翅片表面的温度总是比
制冷剂饱和压力对应的温度要低，应此，必须
考虑在设定压力控制时，制冷剂的温度设定要
高点。请参看下面的表。西克制冷不推荐通过
压力来控制风机延时，因为在采用热力膨胀阀
的系统中，当风机停止时，除霜结束后系统迅
速进入低压状态。对风机延时控制上，建议对
采用压力中止的除霜方式基础上采用时钟。

Fan Delay Requirements – may vary with
application, conditions and control method,
but should not be more than 5 minutes.
Coils – 4FPI (for Low Temp.) and 6FPI(for
medium Temp.) coils (standard coils), should
be operated to the above guidelines unless
otherwise indicated on the installation
concerned.
风机延时要求—风扇延迟需要根据不同的应用
场合而定，但一般来说不应超过 5分钟。
盘管—4FPI(低温) 和6FPI(中温)盘管(标准盘
管) 除非有特殊安装指示，一律按上述的指导
进行安装运行。
Each application should be treated on its
merits, however the following is given as a
guide. During the commissioning, this data
should be used as a reference initially. It is
then necessary to fine-tune the control
settings to achieve the satisfactory defrost
results.
不同的应用需区别对待，请遵从下面的安装指
南。在开机调试时，下面的参数应作为首选参
考值，然后根据实际做相应的调整，达到最佳
的除霜效果。
The above guidelines allow for relatively
heavy defrost loads. Shorter times or lower
settings must be verified on the installation.
Pressure termination given for R407C and
R404A corresponds to the mid point at the
required temperature. Refer to the applicable
Heatcraft Pressure / Temperature Chart.
All data given is for defrost without refrigerant
pump down.
Pump-down is not recommended for electric
defrost using pressure and/or temperature
control. There is clear evidence in testing that
positive defrosting of the distributor, leads,
header and suction line, can not be achieved
without refrigerant being present in the coil.
Additional means, such as heater tape
around these components, may be needed if
using pump-down.
上面的设置参数同样适用于重除霜负荷的工
况。在安装时必须修改时间及温度设定。对
R407C 和R404A 压力设定点取要求温度对应
的中间点。具体请参看西克的压力温度对应
表。
所有给定的除霜参数在无抽空循环的情况下
的。西克制冷不推荐在抽空情况下使用电加热
化霜的方式。根据我们多年积累的经验，分液
器、分液管、吸气集管上的霜如果在盘管内没
有制冷剂存在的情况下是很难除掉的。可能还
会需要其它诸如在这些零部件上加装发热管等
辅助方式。

Routine Maintenance of Unit 设备的日常维护
Longer defrosting time and / or more frequent
defrosting may also be necessary to ensure
long-term ice built up does not occur.
Pump-down may be used with time
termination. The defrost time will be longer
and requirements must be determined on
individual systems.
Data above based on R507/R404A
refrigerant. For other refrigerants, it may be
necessary to vary the number of defrosts per
day to maintain efficient performance.
可能还必须采用延长加热时间，提高加热次数
的方法以避免霜堵。
抽空最好和时间中止一起使用。除霜时间会相
应变长。
上面的数据是基于 R507/R404A 制冷剂的。
对于其他制冷剂，西克建议变化每天的除霜次
数来最佳的除霜效果。
BHDC-H Unit
The advisory defrost data has not been
compiled for the BDHC-H range, the medium

use above low temperature application data
as a guideline to start with, and make
necessary alterations based on observation
and monitoring during the commissioning
BHDC-H 冷风机
推荐的除霜参数不适用于 BHDC-H 冷风机，
对于中温应用工况，工厂已预装了加热丝。在

整。
All BOHN Heavy Duty Evaporators are
designed to have low service maintenance
requirements. Based on normal operation
conditions and working environment, a
service maintenance schedule shall be
established after the successful completion
of commissioning, to ensure the evaporators
operate efficiently and running costs are kept
at a minimum. The following items shall be
checked and recorded during service
maintenance,
•Visually inspect the evaporators looking for
corrosion, unusual vibrations, oil stains and
drain tray blockage. The drain tray should be
cleaned regularly with warm soapy water.
•Clean the evaporator fins by using a soft
brush, low pressurised water and/or
commercially available evaporator coil
cleaner. Never use an acid based cleaner.
Follow label directions for appropriate use.
Flush and rinse coil until no residue remains.
•Coils supplied with ‘Koil Kote’ need special
care so as not to damage the coating. The
coils should not be cleaned with strong
Alkaline Cleaners and/or with stiff brushes.
Mild soapy solutions that are well rinsed after
cleaning should be satisfactory.
所有 BOHN 冷风机都是基于维护较少的前提
下设计的。根据正常的运行工况和环境，在调
试成功后，应准备一份维护时间表，以确保冷
风机在最佳效率下运行，同时保证运行成本最
低。在做维护时，请检查并记录下列各项参
数：
•检查冷风机是否有腐蚀，不正常的振动，油
堵及排水管脏堵。排水管需要经常用温肥皂水
清洗。
•用柔软的刷子清洗冷风机翅片，用低压清水
冲洗盘管或者用市面上买得到的盘管清洗器。
禁止使用酸性清洗剂。请遵循标识的使用指
南。冲刷盘管直至无任何残留物。
•“Koil Kote”盘管需要特殊注意，不要破坏其
涂层。不要用碱性清洁剂或坚硬的刷子来清洗
这类盘管。清洗后最好用中性肥皂水进行冲
淋。

General Decommissioning Guide 关机指南
•Check that each fan rotates freely and
quietly, fan guards are free of airflow
obstructions and fan screws are tight.
•Inspect electrical wiring, connections and
components looking for damaged wiring,
loose connections and worn components.
•Check that all coil heaters are in their
original positions and properly secured, and
that drain tray heater is in proper contact with
the tray and located by the brackets.
•Ensure even coil frost formation pattern on
the air off (fan) side of the coil during
operation. An uneven frost pattern may
indicate a distributor blockage or incorrect
refrigerant charge. The air on side tubes may
contain superheated vapour and may not
frost completely.
•Look for abnormal accumulation of ice
patterns and adjust the defrost cycles
accordingly.
•Check the superheat and adjust TX valve
accordingly.
•检查每个电机风扇转动是否正确，风扇罩是
否有堵塞，螺栓是否拧紧。
•检查电线，接头及其他元件是否有电线损
坏，接线是否松动，元件有无磨损。
•检查所有的盘管加热丝是否在原始位置，是
否安装牢固，检查积水盘管的电加热丝是否和
托盘接触良好，位置是否在托架上。
•在运行时检查在排风侧盘管上的结霜是否均
匀。不均匀的结霜说明分液头有堵塞物或者制
冷剂充注的不正确。在吸风处的盘管上可能因
为有过热气体而无任何结霜现象。
•寻找不正常的结霜状况，根据情况调整除霜
循环。
•检查过热度，相应的调整热力膨胀阀。
All power must be disconnected before cleaning
and/or service maintenance. The condensate
drain tray also serves as a cover of hazardous
(hot, cold, electrical and moving) parts. Operation
of evaporators without condensate drain tray
constitutes a safety hazard.
The service maintenance record as well as this
“BOHN Heavy Duty Evaporators Handbook” shall
be kept together in a safe place as a future
f
在清洗和维修时必须断电。积水盘也是
需要维修的部件(热，冷，电气及运动部
件)。如果冷风机在不安装积水盘情况下
运行是存在安全隐患的。
维护记录和”BOHN 工业型冷风机的操
作手册” 应好好保管以便将来做参考。
In order to remove the evaporator from its
mounting place, the following procedures
need to be carried out professionally by
qualified personnel. Failure to do so may
result in personal injury or death, property
damage by fire or explosion. Discharge of
refrigerant to atmosphere is illegal and may
result in heavy fines by relevant regulatory
authorities.
将冷风机从原来的安装位置移走，必须由专业
的制冷技工遵循下面的程序来进行拆卸。不遵
循该程序将引起操作人员受伤或死亡，并且由
于失火或爆炸引起财产损失。直接将制冷剂排
放到大气中是不合法的，并且会受到监控部门
的严厉罚款。

Material Safety Data Sheets – M.S.D.S. 制冷剂安全数据表-M.S.D.S
•Pump down the entire refrigerant charge
into the liquid receiver or appropriate
container such as reclaim cylinder, and shut
related valves. All reclaimed refrigerant that
is not re-used must be taken to an approved
refrigerant recycling or destruction facility.
•将全部充注的制冷剂抽到储液器或合适的储
液罐，如回收钢瓶，同时关闭相应的阀件。所
有回收的不能再用的制冷剂必须送往合格的制
冷剂再利用或销毁处。
•Disconnect the power supply. Remove all
necessary field electrical wiring and related
components, leaving the earth wire to the
last.
•Disconnect the drainpipe.
•Care must be taken when de-pressing the
Schrader valve core in order to balance the
pressure between the evaporator and
ambient. There may be a small amount of
refrigerant trapped in the oil, the pressure
rise in the evaporator will boil and vaporise
the refrigerant resulting in a potential
personal injury hazard.
•Cut and solder seal the refrigeration liquid
line and suction line pipe connections.
•Remove the evaporator from its mounting
place. Adequate support must be provided to
hold the weight of the evaporator. The use of
weight lifting equipment is highly
recommended whenever possible.
•切断动力供电。移走所有不要的现场接线，
相应的电气元件，最后切断地线。
•断开排水管
•为了平衡蒸发器和外界的压力，在打开针阀
阀心时必须特别小心。在润滑油中溶有一定量
的制冷剂，当冷风机的压力上升时制冷剂就会
沸腾并挥发，这可能会导致人员受伤。
•切断，并密封液管和气管的接头。
•将冷风机从安装位置移走。当需要时，建议
采用起重设备。
