空调缺氟的判定
Determination of fluorine deficiency in air conditioning
1.试:空调正常开启一段时间后，吹到身上的风感到很凉，并能很快达到设定温度，室外的压缩机能像电冰箱一样开一会儿停一会儿，就可以说是正常的。
1. Test: after the air conditioner is normally turned on for a period of time, the air blowing on the body feels very cold and can reach the set temperature quickly. The outdoor compressor can be opened and stopped like a refrigerator for a while, which can be said to be normal.
2.测:用温度计测量室内机的进、出风口的温差，差值在8℃以上为正常，温差越大说明空调的工作情况越好，好的可达15℃左右。
2. Measurement: use a thermometer to measure the temperature difference between the air inlet and the air outlet of the indoor unit. It is normal if the difference is above 8 ℃. The larger the temperature difference is, the better the air conditioner will work, and the better can reach about 15 ℃.
3.看:在开机十几分钟后，打开室内机面板，应能看到蒸发器(铜管上串满铝片进行热交换的部件)上均匀布满冷凝水(像露水一样)，为正常(空气湿度大时多，反之较少)。如果一半有一半没有，可能为缺氟。如局部结霜或结冰也不正常。
3. Look: after starting for more than ten minutes, open the indoor unit panel, and you should be able to see that the evaporator (the part on which the copper tube is full of aluminum sheets for heat exchange) is evenly covered with condensed water (like dew), which is normal (more when the air humidity is high, less on the contrary). If half of them do not, it may be lack of fluorine. If local frost or ice is not normal.
4.摸:如室外机在人手能摸山刷房  保定强夯 卷扬式启闭机  保定网站制作 收费岛模具 遮阳网 麻绳到的地方，可在开机十几分钟后用手摸。室外机有两个铜阀门，一个接粗铜管，一个接细铜管。用手摸两阀门应有温差；粗的应比细的温度低些，摸着比较凉为正常(在温度高时也应有冷凝水)。再摸室外机的热风是不是热呼呼的，如果不大热可能就是缺氟。
4. Touch: if the outdoor unit can be touched by human hands, it can be touched by hand ten minutes after starting. The outdoor unit has two copper valves, one is connected with thick copper pipe and the other is connected with thin copper pipe. There should be temperature difference between the two valves by hand; the coarse valve should be lower than the fine valve, and the cold valve is normal (there should also be condensate when the temperature is high). Touch the hot air of the outdoor unit again to see if it is hot. If it is not hot, it may be lack of fluorine.
