空调收氟的方法

Methods of collecting fluorine in air conditioning

移机、 更换连接配管、 焊接蒸发器之前， 都要对空调器进行收氟；收氟是制冷系统维修中最常用的技能之一，大家必须要掌握。今天希望大家花一分钟时间进来学习下。

Before moving the machine, changing the connecting piping and welding the evaporator, fluorine collection should be carried out for the air conditioner; fluorine collection is one of the most commonly used skills in the maintenance of the refrigeration system, which we must master. Today I hope you will take a minute to come in and study.

1收氟要开制冷模式

1. Refrigeration mode is required for fluorine collection

收氟即回收制冷剂， 将室内机蒸发器和连接管道的制冷剂回收至室外机冷凝器的过程， 是移机或维修蒸发器、 连接管道前的一个重要步骤。

Fluorine collection is the process of recovering refrigerants from the evaporator of indoor unit and connecting pipes to the condenser of outdoor unit. It is an important step before moving the unit or repairing the evaporator and connecting pipes.

收氟时必须将空调器运行在制冷模式下， 且压缩机正常运行。

When collecting fluorine, the air conditioner must be operated in refrigeration mode, and the compressor shall operate normally.

如果房间温度较高（夏季）， 则可以用遥控器直接选择制冷模式， 温度设定到最低16℃即可。

If the room temperature is high (summer), you can use the remote control to directly select the refrigeration mode, and the temperature can be set to a minimum of 16 ℃.

如果房间温度较低（冬季）， 应参照以下两种方法可以选择进行开启。

If the room temperature is low (winter), you should refer to the following two methods to choose to open.

1）、用温水加热（或用于捏住） 室内环温传感器探头， 使之检测温度上升， 再用遥控器设定制冷模式开机 收氟。

1) . use warm water to heat (or hold) the probe of indoor ambient temperature sensor, so as to raise the detection temperature, and then use the remote control to set the refrigeration mode to start the fluorine collection.

2）、制热模式下在室外机接线端子处取下四通阀线圈引线， 强制断开四通阀线圈供电， 空调器即运行在制冷模式下。

2) . in heating mode, remove the lead wire of the four-way valve coil at the outdoor unit terminal, force the power supply of the four-way valve coil off, and the air conditioner will operate in refrigeration mode.

注意： 使用此种方法一定要注意用电安全， 可先断开引线再开机收氟。

Note: use this method must pay attention to the safety of electricity, you can first disconnect the lead and then start the machine to collect fluorine.

2收氟操作步骤

2. Operation steps of fluorine collection

1）、取下室外机二通阀和三通阀的阀帽。

1) Remove the valve caps of two-way valve and three-way valve of outdoor unit.

2）、用内六角关闭二通阀阀芯，蒸发器和连接管道的制冷剂通过压缩机排气管储存在室外机的冷凝器之中。

2) , close the two-way valve core with the hexagon socket, and the refrigerant of the evaporator and the connecting pipe is stored in the condenser of the outdoor unit through the compressor exhaust pipe.

3）、在室外机（主要指压缩机）运行约40s后（本处指空调器运行时间），关闭三通阀阀芯。 如果时间掌握不好， 可以在三通阀维修口接上压力表， 观察压力回到负压范围内时再快速关闭三通阀阀芯。

3) Close the three-way valve element after the outdoor unit (mainly refers to the compressor) operates for about 40s (this refers to the air conditioner operation time). If the time is not well controlled, connect the pressure gauge at the maintenance port of the three-way valve, observe the pressure return to the negative pressure range, and then quickly close the three-way valve core.

4）、压缩机运行时间符合要求或压力表指针回到负压范围内时， 快速关闭三通阀阀芯

4) When the compressor operation time meets the requirements or the pressure gauge pointer returns to the negative pressure range, quickly close the three-way valve core
