It's been four years since golf's 6th, seven w km since summer, and it's been a little bit cold when the air conditioner came in, and it's a little cold now, and if it's too hot for the outside world, it's hard to get down, and the evaporation tanks on the middle control table are ringing, and there's probably no refrigerant. I don't want to go to the 4ss。
Now cars are all r134a because of environmental requirements, not freon, not freon. The consequences of making mistakes are serious。
Specifically, what kind of chiller opens the engine room will always be marked in a visible space, depending on the type of car you have。
R134a
I'll just have to search the ma yun family for a large number of famous brands
Besides, if it's just an addition and not a replacement, it's usually enough to add a bottle a year
Also, the cadets are at ma yun's house. Head
Both domestic and japanese refrigerants can buy everything
We'll find a good weather to dry
Top chart
Start the car, air conditioning is cold, wind speed is maximum, outer circulation is 3 minutes
The pre-connection of the colder vials and the apostilles, bearing in mind that the needle of the opener is returned to the top before twisting the bottles. The bottles should not be too tight and the air in the tube should be filled with a refrigerant exhaust in the system. I guess it's just a twist。
The low-pressure tube is connected, so if you're going to be able to squeez the casket, you're going to press the low-pressure interface, you're going to let go, you're going to shake it。
This diagram looks at low pressure tube interfaces like golf 6
At this point, there will be silk leaks at the end of the bottle, and the air will be drained and sharpened。
View pressure values on the pressure table according to ambient temperature:
How much pressure does a refrigerant need to be replenished? At this point, there is a knowledge that pressure in ac systems varies according to temperature changes in the external environment. In the chart below, the fahrenheit and ac system pressure table confirms that the pressure in the system is high and low, that the system pressure is high to indicate that the refrigerant in the system is higher than the normal value, which in turn is supplemented。
The external environment temperature (fahrenheit temperature) is the pressure pressure of the low pressure table. The following pressure table values are the theoretical constant temperature in the laboratory and the outdoor temperature does not meet this requirement during use. So the owner's friend, in the course of using it, is asked to calculate by the smallest to the smallest value minus 10 psi, which is the normal pressure of the system. The pressure must not exceed the minimum. Once the pressure is exceeded, the compression opportunity is automatically protected, then the cooling effect is poor! If external temperature is 30 degrees, the chart shows 45 psi-55 psi, which is a constant temperature. We should calculate with 45 psi minus 10 psi pressure, with 35 psi, which is the normal system pressure value, preferably not exceeding that value。
65 fahrenheit corresponds to 18. 33 degrees celsius
70 degrees fahrenheit, 21. 11 degrees celsius, system pressure 35-40 psi
75 degrees fahrenheit, 23. 89 degrees celsius. System pressure 35-40 psi
80 degrees fahrenheit, 26. 67 degrees celsius, system pressure 40-50 psi
85 degrees fahrenheit, 29. 44 degrees c. System pressure 45-55 psi
90 degrees fahrenheit, 32. 22 degrees celsius. System pressure 45-55 psi
95 fahrenheit, 35 degrees celsius, system pressure 50-55 psi
100 degrees fahrenheit, 37. 78 degrees c. System pressure 50-55 psi
105 fahrenheit to 40. 56 degrees. System pressure 50-55 psi
110 fahrenheit, 43. 33 degrees celsius, system pressure 50-55 psi
I don't care about myself. I have to add it anyway
And when you spin a clockwise on the opener, you break the bottle, and then you twist the clockwise out, and the refrigerant starts adding to the air conditioning system, and you keep the bottle straight at the beginning, so that you don't hit the air conditioning system too hard and damage the compressor。
If you're too high, you'll be almost stable at 30-40 psi, and you'll shake the bottle over
Feels like the bottle is empty, or needs to stop the bets, and the clockwise penetrating pin goes into the bottle, and grabs the ring and pulls it down quickly。
The last few bets were positive and medium temperature changes
The temperature of the vent was significantly reduced。
And finally, the hood of the engine, the wind is moving back and forth, and the sound in the middle controls is much smaller。
At the first stage, the vent temperature was only five degrees
