1、拆机前应先将空调机内的制冷液收进室外机组中。

1, before the cooling liquid will disassemble inside the air conditioner outdoor unit revenue.

收液步骤：

Take the liquid step:

①、先将空调机置于制冷状态，并开机运行。

First, the air conditioner is placed in the refrigerating state and starts running.

②、将室外机上的高压阀黄铜六角形阀盖打开，用内六角扳手将高压阀门关闭，（在室外机的一侧有两只三通阀门，一只口径大的为低压阀门，一只口径小的为高压阀门）。

2. Open the brass hexagonal valve cover of the high pressure valve on the outdoor machine and close the high pressure valve with the inner six angle wrench. (there are two three valves on one side of the outdoor machine, a large diameter for the low pressure valve, and a small caliber for the high pressure valve).

③、此时空调机仍在运行，因为高压阀门已被关闭，所以制冷液不能再经高压阀门流到室内机进行热交换，而被压缩进了室外机组内。

At this time, the air conditioner is still running, because the high pressure valve has been closed, so the refrigerant can not flow through the high pressure valve to the indoor machine for heat exchange, and it is compressed into the outdoor unit.

④、等运行约3-5分钟，室内机应该不再有冷气吹出，说明制冷液已被全部收到室外机组中了。

4. When running for about 3-5 minutes, no more air coolers should be blown out of the indoor unit, which means that the refrigerating fluid has been all received in the outdoor unit.

⑤、此时再将室外机上的低压三通阀门关闭。此时制冷液就被封闭在室外机组中了。

At that time, the low pressure three way valve on the outdoor unit will be closed again. At this point, the refrigerant fluid is enclosed in the outdoor unit.

2、将空调机关闭，此时可进行拆机操作，拆下室内外机的联接管道，拆下室内外机间的电缆。

2, when the air conditioner is closed, the dismantling operation can be done at this time, the connecting pipes of indoor and outdoor machines are removed, and the cables between indoor and outdoor machines are removed.

3、拆下的联通铜管要注意清洁，用塑料袋将管道口和三通阀门的接口都封起来。

3, we should pay attention to the cleaning of the unblocked copper pipe, and seal the connection between the pipeline port and the three way valve with plastic bags.

空调移机流程第二步——装机

Second step process: air conditioning installed

1、室外机定位，机架安装时要注意水平。

1, outdoor aircraft positioning, rack installation should pay attention to the level.

2、室内机定位，室内机应注意往出水方向略有一点倾斜，如果倾斜方向相反，冷凝将会从室内机内漏到房间里。

2, indoor positioning, indoor machine should pay attention to a slight tilt to the outlet direction, if the direction of the opposite direction, condensation will leak from the indoor machine to the room.

3、联接室内机间的管道和电缆。

3. Connect the pipes and cables between the interior machines.

4、在连接室外机的低压管道和三通阀门时要注意，管接头的拼帽先不要拼紧，略松一点。在接好所有管道后，先将高压阀打开一点，等到有制冷液从低压管道拼帽螺丝外冒出来时，再将低压管的拼帽拼紧。（这样做是为了将连接管和室内机中因封闭系统被拆开，而进入的空气赶出来。）

4, when connecting low pressure pipes and three way valves of outdoor units, we must pay attention to that the pipe cap should not be tightened up and loosely. After receiving all the pipes, the high pressure valve is opened first, when the refrigerant comes out from the cap screw of the low pressure pipe, then the cap of the low pressure pipe is tightened. This is done to drive the air coming into the connecting pipe and indoor machine because the closed system is opened.

5、检查所有联接处都可靠连接后，可将高、低压阀门全部开足，制冷液即进入到制冷循环系统中。

5, check that all joints are connected reliably, all the high and low pressure valves will be fully opened, and the refrigerant fluid will enter into the refrigeration cycle system.

6、开机运行，此时可用钳形表检查空调机总电源线上的线电流。根据空调铭牌上标定的额定电流来判断空调机运行是否正常。一般22OV，一匹半的空调工作电流为6A，大于6A说明制冷液太多，小于6A则说明制冷液太少。

6, boot, line current clamp meter the total power available at this time to check the air conditioner line. According to the rated current rated on the air conditioning nameplate, we can judge whether the air-conditioner is running normally. In general 22OV, the working current of a half air-conditioner is 6A, larger than 6A, indicating that too many refrigerant fluids and less than 6A indicate that the refrigerant fluid is too small.

空调移机流程第三步——加液

The third step: air conditioning process with liquid

1、如需对空调机进行加液可在室外机的低压三通阀上进行。

1, if you want to add air to the air conditioner, it can be carried out on the outdoor low pressure three-way valve.

2、确认空调机使用制冷剂的种类，准备好盛有制冷剂的钢瓶、加液管、加液管和低压三通阀的管接头及合适的板头等工具。

2, confirm the type of refrigerant used in the air conditioner, prepare the steel bottle with the refrigerant, the liquid pipe, the pipe and the low pressure three valve tube joint and the suitable plate head and other tools.

3、关闭空调机。

3, close the air conditioner.

4、将室外机低压三通阀门关闭。

4, turn off the three - pass valve of the outdoor machine low pressure.

5、将阀门另一侧上的加液头管接头盖帽打开。

5, open the cap on the other side of the valve.

6、将加液管的一头和盛制冷剂钢瓶上的阀门出口联接好，另一头接到三通阀门上的加液接头上，拧紧接头螺丝。

6, connect the outlet of the valve on the top of the liquid pipe and the valve on the refrigerant cylinder, and the other end receives the liquid connection on the three way valve, and tighten the connection screw.

7、打开低压三通阀，将空调机置于制冷状态，并开机运行，将钳形表钳在电源线上。

7, open the low pressure air conditioning unit in a three-way valve, cooling condition, and starts to run, the table clamp forceps in power line.

8、运行后，慢慢打开制冷剂钢瓶上的角阀，此时可看到制冷液被压缩机吸入系统中。（因为一般加液管都是塑料管，可看到制冷液在内流动。）

8, after running, slowly turn on the corner valve on the refrigerant cylinder. At this time, we can see that the refrigerant is absorbed by the compressor. Because the general liquid adding pipe is plastic pipe, and it can see the flow of refrigerant.

9、观察钳形表读数，当读数达到要求的数值时，关闭钢瓶上的阀门，再观察一会电流正常，即可关机，如不够，还可再打开钢瓶阀门补加，直到电流正常为之。

9. Observe the readings of the table. When the reading reaches the required value, the valve on the cylinder is closed and the current is normal, then the machine can be turned off. If it is not enough, the cylinder valve can be opened up until the current is normal.

10、关闭空调机，关闭低压三通阀门。

10. Turn off the air conditioner and close the low pressure three - way valve.

11、拆下加液管，拧上三通阀门上加液投的盖帽，注意盖帽上的铜垫是否完好，如不好，需要更换密封铜垫。

11, remove the liquid pipe, screw up the cap on the three way valve and add the liquid filler cap, and notice whether the copper pad on the cap is intact. If not, replace the sealed copper pad.
