Installation And Maintenance Instructions

安装维护使用说明

机组配管侧及风机、电机的检修门一侧，应留有足够的操作空间和吊顶入孔，以方便日常维护及检修。

Sufficient operating space and ceiling access holes should be left on the piping side of the unit and the side of the inspection doors for the fans and motors to facilitate daily maintenance and inspection.

●机组与外接风管、水管连接，应采用柔性接头以避免振动传递。

When the unit is connected to external air ducts and water pipes, flexible joints should be used to prevent vibration transmission.

外接管与机组进出水管驳接时，应避免用力过猛而损伤盘管，外接管之重量不得由机组承担。

When connecting the external connection pipe to the inlet and outlet water pipes of the unit, excessive force should be avoided to prevent damage to the coil. The weight of the external connection pipe must not be borne by the unit.

●机房内应设地漏，以方便冷凝水排放及清洗机组时污水排放。

Floor drains should be installed in the computer room to facilitate the discharge of condensate water and wastewater during the cleaning of the units.

●机组冷凝水管出口应先接"U"形存水弯，再接排水管，并确保排水管沿水流方向有不少于0.5%的坡度，以保证排水顺畅。 帆组々凝小山口应九接u川停小与，再按小旨，开洲不H小官口小ル力有个少了0.J时城反，以体证H小顺物

The outlet of the condensate pipe of the unit should first be connected to a "U" -shaped trap, and then to the drainage pipe. It is necessary to ensure that the drainage pipe has a slope of no less than 0.5% along the direction of water flow to guarantee smooth drainage.

存水弯作法如上图(左)所示：

The construction method of the trap is shown as above (left)
The motor wiring diagram is as shown in the above figure (on the right)

机组运行前，应当首先拆除机组内减振系统的锁定装置（如下图，即贴有"运行前拆除”标识的运输固定钣金），使其减振功能恢复。

Before the unit is put into operation, the locking device of the vibration damping system inside the unit (as shown in the following figure, that is, the transport fixed sheet metal marked with "Remove before operation") should be removed first to restore its vibration damping function.

Common Fault Solution

常见故障解决方法

●机组积水无法排出The accumulated water inthe unit cannot be drained

对于吸入式空调系统。在冬、夏季的运行中，会由于喷蒸汽加湿系统的带水或者由于空气冷却处理而产生的凝结水不能排出空气处理室而积存于空气处理室或集水盘内，在空调系统的运行中，往往容易使系统送风控制点移动而无法保证室内相对湿度。

For suction air conditioning systems. During the operation in winter and summer, the water carried by the steam humidification system or the condensate water produced by the air cooling treatment cannot be discharged from the air handling chamber and accumulates in the air handling chamber or the water collection tray. In the operation of the air conditioning system, this often causes the risk control points of the system to move, making it impossible to ensure the relative humidity inside the room.

出现此类问题的原因基本上在于在空调排水管上未装水封，或虽装了水封但水封的尺寸不适合所致，因而使空调系统在运行中由于其内的负压作用而导致内部的积水无法排出。水封的具体尺才应根据排水口处的负压值决定。

The main reason for such problems lies in the fact that no water seal is installed on the air conditioner's drain pipe, or even if a water seal is installed, its size is not suitable. As a result, during the operation of the air conditioning system, due to the negative pressure inside, the accumulated water inside cannot be discharged. The specific size of the water seal should be determined based on the negative pressure value at the drainage outlet.

表冷器冬季冻裂The surface cooler cracked due to freezing in winter

避免机组内水冷式表面冷却器冬季运行中冻裂的方法有以下几种：

There are several methods to prevent the water-cooled surface cooler inside the unit from cracking due to freezing during winter operation:

1）在冬季温度较低的地区，在空调系统中应设置新风预热器（预热盘管或电加热器），使进入机组内的新风温度提高到0℃以上(一般可将新风温度提高到+5℃左右)。

1) In regions with relatively low winter temperatures, a fresh air preheater (preheating coil or electric heater) should be installed in the air conditioning system to raise the temperature of the fresh air entering the unit to above 0°C (generally, the fresh air temperature can be raised to around +5°C).

2）对于设置有表冷器、加热器、加湿器的空调系统，如果在夏季运行中系统的机器露点即为送风状态点（无需再热）时，可将加热器置于表冷器之前。这样空气在冬季的运行中，低于0℃的空气首先经过加热器的升温而高于0℃，就不会使表冷器再发生了冻坏现象。

2) For air conditioning systems equipped with surface coolers, heaters and humidifiers, if the dew point of the system's machines is the supply air state point during summer operation (no further heating is required), the heater can be placed before the surface cooler. In this way, during winter operation, the air below 0 will first be heated by the heater and rise above 0, thus preventing the surface cooler from being damaged by freezing again.

3）如果空调系统较小，系统的新风量也较小，可在新风管路位于空调机房的管段上再设置一个新风口（空调机房内空气无污染时），同时在两个新风口各装设一个密闭式对开多叶调节阀。这样空调系统在夏季运行时，可随便关一个新风阀，开启另一个风阀；而在冬季运行时，可关闭室外的新风阀，打开空调机房内新风管段上的新风阀。对于设有采暖的空调机房，由于机房内的空气温度肯定高于室外空气温度且高于0℃，这样采用空调机房内的空气作为新风进入机组即可避免机组内的水冷式表冷器冻坏的现象。当室外空气温度高于0℃后即可关闭空调机房内新风管段上的新风口而打开室外的新风口进行运行。

3) If the air conditioning system is small and the fresh air volume of the system is also small, an additional fresh air inlet can be set on the section of the fresh air pipeline located in the air conditioning machine room (when the air in the air conditioning machine room is not polluted), and at the same time, a closed double-leaf regulating valve can be installed on each of the two fresh air inlets. In this way, when the air conditioning system is operating in summer, one fresh air valve can be closed at will and another can be opened. When operating in winter, the outdoor fresh air valve can be closed and the fresh air valve on the fresh air duct section inside the air conditioning machine room can be opened. For air conditioning machine rooms equipped with heating, since the air temperature inside the machine room is definitely higher than the outdoor air temperature and above 0°C, using the air inside the air conditioning machine room as fresh air to enter the unit can prevent the water-cooled surface cooler inside the unit from freezing and being damaged. When the outdoor air temperature exceeds 0°C, the fresh air outlet on the fresh air duct section in the air conditioning machine room can be closed and the outdoor fresh air outlet can be opened for operation.

4）目前，有些机组的新风与回风采用平行进入的方式，这种方式下利于新、回风混合，尤其是在冬季，极易产生空气的分层。一旦位于底部低于0℃的冷空气通过表面冷却器时，就可能发生水冷式表面冷却器冻环的现象。因此，机组的新风与回风最好采用互为垂直进入的方式，同时在新、回风入口处安装对开多叶调节阀。新风、回风在经过新、回风混合段和空气的初效过滤段后，混合就比较充分。同时由于空调系统在冬季运行时所采用的新风比例较小，因此一般其混合后的空气温度都会高于0℃。如一空调房间内冬季温度按tn=18℃，相对湿度为50%，室外新风温度tw=-10℃，相对湿度为25%，新、回风比为1：3，则其新、回风混合后的空气状态点的干球温度远高于0℃，这样就可以避免机组内的表冷器被冻坏的现象发生。

4) At present, in some units, the fresh air and return air enter in parallel. This method is conducive to the mixing of fresh and return air, especially in winter, which is very likely to cause air stratification. Once the cold air at the bottom below 0°C passes through the surface cooler, the phenomenon of the water-cooled surface cooler freezing ring may occur. Therefore, it is best for the fresh air and return air of the unit to enter perpendicularly to each other, and at the same time, install split multi-leaf regulating valves at the fresh air and return air inlets. After passing through the fresh and return air mixing section and the primary air filtration section, the fresh air and return air are well mixed. At the same time, since the proportion of fresh air adopted by the air conditioning system during winter operation is relatively small, the temperature of the air after mixing is generally above 0°C. If the winter temperature in an air-conditioned room is tn=18C, the relative humidity is 50%, the outdoor fresh air temperature tw=- 10°C, the relative humidity is 25%, and the ratio of fresh air to return air is 1:3, then the dry bulb temperature of the air state point after the fresh air and return air are mixed is much higher than 0°C. This can prevent the phenomenon of the surface cooler in the unit being damaged by freezing.

5）采用一班制运行的空调系统，在冬季运行中，于下午下班停机时，必须关闭系统的新、回风阀及送风阀，避免由于烟囱效应而使低温空气进入机组内而造成表冷器冻坏。必要时要打开机组新风段上的检修门，使设有采暖的空调机房内高于0℃的空气进入机组内。或者，在空调系统停机后、使装于加热器的流量调节阀保持一定开度，使少量热媒仍能进入空气加热器内，使其向机组内散热，以保持空调内的温度始终高于0℃，即可防止水冷式表面冷却器的冻坏。

5) For air conditioning systems operating on a single-shift system, during winter operation, when the system stops at the end of the workday in the afternoon, the fresh and return air valves as well as the supply air valve must be closed to prevent low-temperature air from entering the unit due to the chimney effect and causing damage to the surface cooler. When necessary, the inspection door on the fresh air section of the unit should be opened to allow the air above 0°C in the air conditioning room with heating to enter the unit. Alternatively, after the air conditioning system is shut down, keep the flow control valve installed in the heater open to a certain extent, allowing a small amount of heat medium to still enter the air heater and dissipate heat into the unit, so as to keep the temperature inside the air conditioner always above 0°C, which can prevent the water-cooled surface cooler from freezing and being damaged.

送、回风机无法启动The supply and return fans cannot be started

一般在空调系统的送风管路和回风管中都安装有防烟防火阀，而且防烟防火阀与送、回机实行联锁住制，即防烟防火阀只有处于开启状态，风机才有可能启功运行，而一旦防火阀处于关闭状态时，风机将无法启动，而且风机在运行中如果风管中的防烟防火阀自动关闭，则空调系统中的风机将会自动停止运转。

Generally, smoke and fire dampers are installed in the supply air ducts and return air ducts of air conditioning systems. Moreover, the smoke and fire dampers are interlocked with the supply and return air units. That is, the fan can only start operation when the smoke and fire damper is in the open state. Once the fire damper is in the closed state, the fan cannot start. And if the smoke and fire damper in the air duct automatically closes during the operation of the fan, Then the fan in the air conditioning system will automatically stop running.

因此，在送风总管和回风总管上装有防烟防火阀的空调系统，在供电及负荷正常情况下，风机供电主回路中的熔断器、热续电器等无异常，同时又无超温报警信号，正常运转的风机突然停止转动，或处于停机状态的风机无法启动时，一般为防烟防火阀自动关闭所致。遇到此情况时，应进行认真、细致的检查，在确认不是由于产生烟雾、火警所致时可使防烟防火阀复位，使风机继续投入运行。

Therefore, in air conditioning systems with smoke and fire dampers installed on the supply and return air main ducts, when the power supply and load are normal, there are no abnormalities in the fuses, thermoelectric heaters, etc. in the main power supply circuit of the fan, and there is no over-temperature alarm signal, if the normally operating fan suddenly stops rotating or the fan in the shutdown state cannot be started, it is generally caused by the automatic closing of the smoke and fire damper. When encountering such a situation, a careful and meticulous inspection should be carried out. Once it is confirmed that it is not caused by smoke or fire, the smoke and fire damper can be reset to allow the fan to continue operating.

●机组哨叫声 Crew whistle call

在空调系统的运行中，经常会发生从机组的检查门与壁板、风管检查门与风管之间的缝隙处，以及送风口处的高效过滤器与安装框架之间的缝隙处发出刺耳的哨叫声的现象。产生这种现象的原因，大都是由于两个接触面之间的缝隙处有个别地方不严密，形成很小而狭长的缝隙或针孔，气流是由缝隙或针孔处高速喷出或吸入所形成。

During the operation of the air conditioning system, it is often the case that shrill whistling sounds are emitted from the gaps between the inspection door of the unit and the wall panel, between the inspection door of the air duct and the air duct, and between the high-efficiency filter at the supply air outlet and the installation frame. The reason for this phenomenon is mostly that there are some areas in the gap between the two contact surfaces that are not tight, forming very small and narrow gaps or pinholes. The airflow is formed by the high-speed ejection or suction from the gaps or pinholes.

此现象的处理方法较为简单，可将两接触面压紧，或将两接触面进行重新平整后再压紧，或将两接触面上粘着的已老化、变化或局部脱落的衬垫清理干净，重新将新的密封衬垫平整地进行粘结，然后使两个接触面均匀、平整地互相压紧即可消除哨叫声。

The treatment method for this phenomenon is relatively simple. You can press the two contact surfaces tightly, or flatten the two contact surfaces and then press them again, or clean the aged, changed or partially fallen gaskets adhering to the two contact surfaces, and then flatten the new sealing gaskets. After that, press the two contact surfaces evenly and flatly against each other to eliminate the whistling sound.
