7 功能
7.1 配置与功能
设备配置：
1 ） 高品质关键零部件
2 ） 压缩机保护装置
3 ） 智能控制系统
4 ） 冷凝水蒸发器 （可选）
5 ） 2~400V 交流供电（可选）
设备功能 :
1 ） +15 ℃ ~+55 ℃外部环境温度
2 ） 内部控制温度 + 25 ℃ ~+45 ℃
3 ） 上电自检和运行中实时自检
4 ） 冷凝水蒸发器（可选）
5 ） IP54/IP34 防护
6 ） 2~ 400V 交流供电（可选）
注意：
机柜空调的具体功能见随机附带的技术规格书。
7.2 工作原理
1 压缩机
2 换热器（冷凝器）
3 截流装置
4 换热器（蒸发器）
5 风机，外循环
6 风机，内循环
7 带温度传感器的电子控制系统
压缩机（ 1 ）将制冷剂压缩到高压。在这个过程中温度升高。
冷凝器（ 2 ）中，热量散失到周围环境空气中，制冷剂变成
液体。冷凝器风扇（ 5 ）吸入并使空气通过冷凝器，然后
排放出去。
在截流装置（ 3 ）中，冷却液的压力下降。在蒸发器（ 4 ）中，
冷却剂吸收机柜内空气中的热量并蒸发。因此，来自机柜
中的空气被冷却下来；同时机柜内的空气被除湿。蒸发
器风扇（ 6 ）吸出机柜内的空气并迫使其通过蒸发器，冷却
空气吹回到机柜内。
机柜空调是由电子系统控制的。温度传感器（ 7 ）记录了机
柜内的空气温度。
所使用制冷剂不损害臭氧层，而且不可燃。
7.3 冷凝物
在蒸发器上发生的冷却过程中，空气中的水分被凝聚成冷凝
水。为了避免对电控柜及本制冷系统发生任何损害，必须排
出冷凝水。
冷凝水排放方式如下：
•带冷凝水蒸发器（可选）的制冷设备在正常情况下，可以
蒸发掉水分。但为防止蒸发器故障后产生的冷凝水溢流，请
连接冷凝水管路 , 然后再通过水管排出。
始终确保冷凝水正确地排出。
在特定情况下有可能会发生凝结水过量，例如，机柜不密
封或机柜内部温度经常低于露点温度。
注意：
在正常运行过程中发生冷凝水过量 , 请检查机柜的密
封。
我们建议安装一个门接触开关，当机柜门被打开时 , 机
柜空调将自动关闭 , 以防止过度冷凝水。
8 安装
8.1 概述
• 正确选择机柜空调在机柜上的安装位置 , 保证良好的通风。
• 机柜空调之间或是机柜空调和墙壁的距离必须保证至少
200 毫米。
•在机柜内部，空调的电器连接端子处需预留至少 40mm 空间 .
在机柜内部，电气元件不得阻碍空气循环。
• 机柜空调在安装时，机柜空调的电源必须断开！
• 安装现场必须受到保护，免遭污染。
注意：
如果机柜空调是装在机柜门上，必须检查门的铰链能够
支持机柜空调的重量或当门被打开机柜时,不会翻倒。
注意：
金属碎屑可能损坏机柜。
如果在安装现场开安装孔，确保使用保护罩 , 以免切屑
进入机柜，损坏电气元件。
提示
为方便机柜空调安装， M8 的吊环可以旋入机柜空调顶部固
定，方便吊装，简单 ― 一人安装 ‖ 就能实现。
8.2 安装工作
机柜安装面要开好空气通风口和螺栓安装固定孔，尺寸根据
随机组所附图纸。所附图纸同时说明了电气连接接口位置和
通风口位置。
1) 如机柜未预留机柜空调的开口，在机柜上切出开口（尺寸
见随机组所附图纸），然后去除剪边毛刺。
2) 取出附件包内密封条（标号 8 , 9 或 10,11,12 ）贴在门板外侧
（如图）。先将密封条 8 或 11 上的孔与门板圆孔同心后再

685408014B4
按压在门板上，然后将密封条 9 或 10 或 12 外边线与 8 或 11 外边
线对齐后贴在门板上。
3) 在机柜内侧，取出附件包内的螺栓、平垫片、弹垫、螺母
及螺栓（标号 3,4,5,6,7 ）将空调锁紧。
4) 将出水管通过机柜空调底板，使冷凝水能自由流下，并将
水管切至所需长度。
1 机柜空调组 5 弹簧垫片
2 机柜侧板或机柜门 6 螺母
3 牙棒 7 螺栓
4 平垫片 8-12 密封条
5 ）如果机柜空调在安装时拆下外壳顶部的 M8 螺母，需将其
安装好。
6) 将电线按照接线图（见机柜空调背部）连接到连接头（附
件包中），并连接到机柜空调。
- 导线尺寸： 1.0 –2.5 平方毫米或 AWG18 - AWG14
（在电缆的大小选择，应参照相关法规要求！）
7) 将机柜空调插上电源（见 8.3 ）
不同机器可能安装方式不同，请参考随机资料。
8.3 电气连接
注意：
• 机柜空调应当经由断路器连接到电源（请选择合适的断
路器），断开断路装置时 , 其触点间隙应不少于 3 毫米。
• 电源线上不可以串接温度传感器。

10 投入使用和功能
• 机柜空调包含的功能及可选项见章节 7.
10.1 概述
机柜空调配有温度控制系统。机柜内部温度通过温度传感器
来测量。通过操作显示器可以设定不同的机柜内温度（见附
表）。

5 685408014B
机柜空调具有上电检测、运行时实时监测功能。上电检测过
程中如果有故障，空调会发出相应的报警，这使得在进入工
作模式之前更方便的排查设备故障。
警告
机柜空调只能在装有前盖的情况下运行，否则会因散
热不良造成机柜空调被损坏。
10.2 操作显示器
机柜空调装有操作显示器。上电后操作显示器显示 0.0 ℃ ,3S
后显示柜内实时温度，表明机组在正常操作模式。如果发生
故障或有报警输出时，操作显示器显示报警代码，警报灯点
亮并伴随报警声，这使诊断机柜空调故障更容易（见章节
14 ）。
10.3 启动测试模式
通电前，若门触点断开，则机柜空调不启动，直到 门触点闭
合后，机柜空调进入自测试模式 , 自测试模式将不受外部环境
影响。机柜空调运行启动模式持续 30 秒 , 之后是测试模式持
续 110 秒。测试模式时，有故障设备继续运行，直到测试模
式结束，产生相应的报警代码，如有故障则需解除故障后进
入正常工作模式，如无故障，直接进入正常工作模式。

Caution:
Please refer to the attached technical specification for the
details function of the cooling unit.
7.2 Operating principles
The compressor (1) compresses the refrigerant until high
pressure is achieved. During this process temperature
increases. In the condenser (2) heat is dissipated to
ambient air, the coolant becoming liquid. The condenser
fan (5) of the compensate takes ambient air in through the
condenser, and then it releases the air.
In the expansion valve (3) the pressure of the coolant
drops. In the evaporator (4) the coolant absorbs heat from
the air in the switch cabinet and evaporates. Thus, the air
in the switch cabinet cools down.At the same time the air
inside the switch cabinet is being dehumidified. The
evaporator fan (6) sucks the air out of the switch cabinet
via the evaporator, the cooled air flows back to the switch
cabinet.
The cooling unit is electronically controlled. For that
purpose a temperature sensor records the temperature of
the air inside the switch cabinet (7).
The refrigerant is not detrimental to the ozonosphere; it is
hardly combustible.
7.3 Condensate
During cooling on the evaporator the moisture removed
from the air is collected as condensate. In order to avoid
any damage to the switch cabinet and the cooling unit,
the condensate must be discharged.

685408014B12
The condensate is discharged in the following way:
•In case of normal condensate drainage a reservoir
(option) collects the condensate which is then drained by
means of a hose.
Always ensure that the condensate is drained properly
(safety- drainage).
Excessive condensation can occur if, for example, the
switch cabinet is not sealed or if the internal temperature
of the switch cabinet is frequently below the dew point.
Caution
Please check the sealing of the switch cabinet, if there is
excessive condensate during the normal operation.
In order to prevent the excessive condensate so we
recommend to installed a door contact switch. It will
switch off the cooling unit when the switch cabinet door is
opened.
8 Installations
8.1 General
•In order to keep the cabinet‘s proper ventilation, it is
important to select the correct installation place for the
cooling unit.
•It must be keep the distance at 200mm at least for the
single units or the unit and the wall.
•The cooling unit‘s electrical connection terminal to be
reserved at least 40mm space and the electrical
components shall not impede air circulation in the internal
cabinet.
•It must be switch off the power supply when the cooling
unit installed.
•The site of installation must be protected against
contamination.
Caution:
If the cooling unit is mounted on an switch cabinet door, it
must be confirmed that hinges can support the additional
weight or that the switch cabinet will not topple over when
the door‟s opened.
Caution: Chips may damage the switch cabinet.
It must be use a cover sheet to void the sward enter into
the cabinet to damage the electrical components when
you are installing a hole in the installation site.
Hint
To facilitate installation with heavy units, M8 lifting eyes
can be screwed into the upper fixing on the equipment
housing. Simple‟‟ one man installation‟‟ is thereby
possible.
8.2 Installation work
The mounting surface of the switch cabinet is to be
provided with cutout(s) and holes for air ventilation
openings and for securing the unit according to the
accompanying sheet.
The drawing on the accompanying sheet also shows the
location of the electrical connections and ventilation
openings.
1) If the cabinet is not reserved for the opening hole of the
cooling unit, please cut-out on the cabinet (refer to the
drawing on accompany sheet), then remove burrs from
the cut edge.
2) Please take out sealing strips (Pos.8, 9 or 10, 11, 12)
on the outside of the cabinet, make sure the hole of
sealing strip 8 or 11 concentric with switch cabinet, the
sealing strip 9 or 10 & 12 and 8 or 11 align at outside line,
then paste sealing strip on the swith cabinet.
3) Please take out the thread rod, flat gasket, spring
washer, nut and bolt (Pos. 3, 4, 5, 6, 7) on the inside of the
cabinet and lock the cooling unit tightly.
4) Feeding the condensate run-off tube through the
opening in the base of the unit. Lay the tube with a
downward fall. Shorten as required.

10 Putting into operation and function
•Please refer to section 7 for the cooling unit which
including the function and options.
10.1 General remarks
The cooling unit is provided with an electronic control
system.The cooling unit‘s internal temperature is

685408014B14
measured by temperature sensor.The cooling unit can be
set at different internal temperature through operating
console display, (See attached table) the system will
Disallowed when exceeds the limit temperature.
The cooling unit has the function of power-on self-test, the
run-time real-time monitoring. The cooling unit will
generate an alarm when there is a failure during power-on
self-test.
Caution: The cooling unit can only run in the case
of installing the front cover, otherwise it will be damaged
by poor heat dissipation.
10.2 Operate the display
The cooling unit is provided with an operation display.
―0.0℃‖ is displayed for 3s after the supply power is
switched on, then internal temperature is shown. This
indicates the unit works properly. If there is a failure or an
alarm, the operation display‘s alarm lamp will be light and
accompanied by an alarm sound, which makes it easier to
diagnose the cooling unit. (Refer to section 14)
10.3 Start-up / Test mode
The cooling unit will can‘t work If on front of get supply
power the door switch is open, The test mode is basically
activated after renewed connection of the supply voltage
and is independent of the instantaneous ambient
conditions when the door contact is closed.First of all the
unit runs though a start-up mode lasting 30 seconds
which is followed by a test mode lasting 110 seconds. The
unit will still running when there is an alarm during the test
mode. After finishing the test mode, if have alarms, show
the alarm code in the panel, must take off the alarm, it can
enter into a normal working mode if there is no failure.
