Automobile air conditioning refrigerant DIY filling method
Automotive air conditioning refrigerant supplement, and the same as the tire gas and convenient.
General car air conditioning every year will normally lose about 10% of the refrigerant, which is due to the choice of automotive air conditioning compressor seal (car air conditioning compressor is semi-sealed). As long as we regularly to the car every year to add air conditioning detection of refrigerant on it. Do not need to worry about the use of methods, the following I tell you friends friends DIY car air conditioning detection method. Friends can try to raise their own hands with refrigerant.
Methods as below:
1. need to prepare a car air conditioning DIY detection supplement tube.
2. A bottle of vehicle with R134A refrigerant.
3. Now start to test the pressure to the car: the first DIY to add the tube in the bottle top throttle clockwise rotation to the top, the refrigerant bottle into the opener, tighten.
4. Find low-voltage interface generally under the hood in the left side of the end of a blue or black little hat, hat above a L word, the hat off.
5. Turn the car engine on and turn on the air conditioning AC switch, the blower open to maximum, run and wait for three points. Connect the DIY pipe interface to the low pressure side of the car air conditioner.
6.DIY tube access low-voltage interface, the DIY tube pressure gauge will instantly have a scale indication. At this time the pressure gauge on the DIY tube is consistent with the air conditioning system pressure, look at the pressure gauge on the pressure scale, you know the pressure in the system. How much pressure does it need to add to the refrigerant? At this time there is a knowledge that! The pressure in the air conditioning system varies according to the ambient temperature.
External ambient temperature (Fahrenheit) The pressure of the low pressure gauge, the following pressure gauge value is the theoretical value of the temperature in the laboratory, the use of the outdoor temperature is not up to this requirement. So the owner of the owner in the use of the chart according to the minimum value of the calculation, the calculation method is the minimum to the minimum 10PSI calculation are the system normal pressure, the pressure must not exceed the minimum, the pressure once exceeded, the compressor will automatically protect , Then the cooling effect will be very poor! If the external temperature at 30 degrees, the chart shows 45PSI-55PSI, which is constant temperature value. We should be calculated with 45PSI minus 10PSI pressure, the result is 35PSI, which is the system normal pressure value, it is best not to exceed this value, less than 35PSI is the need to add.
Fahrenheit 65 corresponds to 18.33 degrees Celsius system pressure 25-35PSI
Fahrenheit 70 corresponds to 21.11 degrees Celsius system pressure 35-40PSI
Fahrenheit 75 corresponds to 23.89 degrees Celsius system pressure 35-40PSI
Fahrenheit 80 corresponds to 26.67 degrees Celsius system pressure 40-50PSI
Fahrenheit 85 corresponds to 29.44 degrees Celsius system pressure 45-55PSI
Fahrenheit 90 corresponds to 32.22 degrees Celsius system pressure 45-55PSI
Fahrenheit 95 corresponds to 35 degrees Celsius system pressure 50-55PSI
Fahrenheit 100 corresponds to 37.78 degrees Celsius system pressure 50-55PSI
Fahrenheit 105 corresponds to 40.56 degrees Celsius system pressure 50-55PSI
Fahrenheit 110 corresponds to 43.33 degrees Celsius system pressure 50-55PSI
7. Air conditioning system, low pressure, the need to add refrigerant, the opener in the thimble clockwise rotation, piercing the refrigerant bottle, the opener in the throttle immediately counterclockwise rotation to the top, (Note: this time the pressure The scale of the table will show up to 100PSI to 110PSI, 2 seconds after the pressure gauge scale will slowly come down, back to the original display scale, it is normal, because the bottle was pierced, the pressure out, This time the pressure in the bottle is shown in the R134A bottle. The pressure of the bottle is absorbed by the compressor and is shown as the pressure in the system!) Cry the refrigerant bottle, the refrigerant gas will flow into the system, and watch the pressure gauge , With the above figure temperature and pressure PSI unit can be. Note: Do not reverse the refrigerant bottle! The The (Except for oil mixture)
Note: In the absence of piercing the refrigerant bottle, DIY tube in a little air, if the owner if you need to drain a little air in the tube, please do the following, do not pierce the refrigerant bottle when the refrigerant bottle And the opener gently release a little, then the DIY tube in the air will be air-conditioning system out of the refrigerant, then immediately tighten the refrigerant bottle can be! The The
8. When observing the normal pressure gauge scale, please immediately turn the thimble in the opener clockwise to the bottom and tighten, remove the low-port connector of the air conditioning system. If the bottle is not enough to add, please add the second bottle of refrigerant as described above, until the outside temperature and the system pressure to the end.
9. At this time the car air conditioning system refrigerant supplement to complete, please tighten the L word hat.
Note: The above pressure scale and filling method is the United States refrigerant sales company ID and EF filling instructions, their successful completion of a successful filling, and feel like the tires of car tires as convenient!
汽车空调制冷剂DIY加注补充方法
汽车空调制冷剂补充,就和轮胎冲气一样的方便,安全。
一般的汽车空调每年都会正常损失10%左右的制冷剂,这是由于汽车空调压缩机密封方式决定的(汽车空调压缩机是半密封式)。我们只要每年定期给汽车空调检测补充制冷剂就可以了。不需要担心使用方法,下面我告诉各位车友朋友DIY汽车空调检测补充方法。朋友可以尝试自己动手加注制冷剂。
方法如下:
1.需要准备一根汽车空调DIY检测补充管。
2.一瓶车用R134A制冷剂.
3.现在开始给汽车检测压力:先将DIY补充管开瓶器端中的顶针反时针旋转至最顶端,将制冷剂瓶子旋进开瓶器中,旋紧。
4.找准低压接口一般在引擎盖下左侧端有个兰色或黑色小帽子,帽子上面有个L字,将小帽子旋下来。
5.将汽车发动机起动并打开空调AC开关,鼓风机开至最大,运转并等待三分种。将DIY管子接口接入汽车空调低压端。
6.DIY管接入低压接口后,DIY管压力表就会瞬间有刻度指示。这时DIY管上的压力表刻度是与空调系统压力是一致的,看压力表上的压力刻度,就知道系统中的压力了。在多少压力时需要补充制冷剂呢?这时有一个知识说明!汽车空调系统中的压力是根据外界环境温度变化而变化的。
外界环境温度(华氏温度) 低压表的压力,以下压力表数值是实验室中理论恒温值,在使用过程中室外温度是达不到这个要求的。所以车主朋友在使用过程中请按图表数值中最小值计算,计算方法是最小值到最小值减去10PSI计算都是系统正常压力,压力千万不能超过最小值,压力一旦超过,压缩机会自动保护,这时制冷效果反而会很差!如外界温度在30度时,图表显示为45PSI-55PSI,这是恒温数值。我们计算时应该用45PSI减去10PSI压力,结果为35PSI,这就是系统正常压力值,最好不超过这个数值,低于35PSI就是需要补充的。
华氏65对应 18.33摄氏度 系统压力25-35PSI
华氏70对应 21.11摄氏度 系统压力35-40PSI
华氏75对应 23.89摄氏度 系统压力35-40PSI
华氏80对应 26.67摄氏度 系统压力40-50PSI
华氏85对应 29.44摄氏度 系统压力45-55PSI
华氏90对应 32.22摄氏度 系统压力45-55PSI
华氏95对应 35 摄氏度 系统压力50-55PSI
华氏100对应 37.78摄氏度 系统压力50-55PSI
华氏105对应 40.56摄氏度 系统压力50-55PSI
华氏110对应 43.33摄氏度 系统压力50-55PSI
7.空调系统中压力低,需要补充制冷剂,将开瓶器中的顶针顺时针旋转,刺穿制冷剂瓶口,开瓶器中的顶针立刻反时针旋转至顶,(注:这时候压力表的刻度会显示最高到100PSI到110PSI,2到时候秒钟后压力表的刻度会慢慢降下来,回来原来显示的刻度上,这是正常的,因为瓶子被刺穿后,有压力出来,这几秒钟显示的是R134A瓶子中的压力,瓶子的压力被压缩机吸收后就显示为系统中的压力了!)轻摇制冷剂瓶,制冷剂气体会流入系统中,同时看压力表刻度,与上图温度与压力PSI单位一至即可。注:制冷剂瓶子请勿倒立!!!(油剂混合物除外)
注:在没有刺穿制冷剂瓶时,DIY管中有一点空气,如果车主如要需要将管子中的一点空气排掉,请按以下方法做,在没有刺穿制冷剂瓶时将制冷剂瓶子和开瓶器轻轻松开一点,这时DIY管中的空气会被空调系统中制冷剂冲出去,这时即刻旋紧制冷剂瓶即可!!!
8.观察到压力表刻度正常时,请立即将开瓶器中的顶针顺时针旋转至最下端并旋紧,拆下空调系统低端口接头即可。如一瓶加入后不够,请按上叙述方法加入第二瓶制冷剂,直至外界温度与系统压力一至为止。
9.这时汽车空调系统制冷剂补充以完成,请将L字小帽子旋紧。
注:以上压力刻度和加注方法是美国制冷剂销售公司ID和EF的加注说明,自己完成一次成功加注后,会觉得和汽车轮胎冲气一样的方便!
