Detailed graphics: DIY to add refrigerant in automobile air conditioning
Kunming's hot weather early, this is not the first to enter in March, temperatures dally up, seeing is 29 degrees, the car has been almost 5 years old, recently that air conditioning suck, to think of the car of R134a 4S, we will not go to a roadside shop, ask the price, people say "260 yuan", gee, this price is quite expensive, one would like to forget, not do not add refrigerant, what is too difficult, on everything # treasure Amoy, refrigerant and tools are also cheap, I thought it was added to the car after every year a refrigerant, took a bite teeth, today is all right, do it yourself to the car to fill the refrigerant. OK, here!
1, it is the supplement of refrigerant three in one tool (bottle opener, pressure gauge, connecting head), containing a total of express how much money?
This is the pressure gauge This is a bottle opener
This is a quick joint
Snow, took three bottles,
3, launch the car, turn on the air conditioner to the cold state, and the open loop mode, wait for 3 minutes.
4, open the hood, find the Aluminum Alloy tube (usually on the left), a tube with a green dust cover, they are labeled "H" is a high pressure pipe, they are labeled "low L", is to inject refrigerant from the low pressure pipe.
This is a high end This is the low end
5、Then the bottle opener screw turning the knob in the refrigerant, until you feel tight, stop.
Low pressure pipe dust 6, screw opening "L" on the cover, you can see the device as the valve core the same, then the joint filling tool according to the end.
7, this time, pressure gauge pointer will have reaction, the internal pressure is shown in the car air conditioning. I was only 25, early to add time! (photo handshaken, a little flower)
8, at this time, can open the bottle a little loose end of the pipe in the air clean, how to tighten. Then the clockwise twist knob until the screw does not move far, let the bottle pierce the refrigerant, then slowly loosen knob counterclockwise, so that the refrigerant flowing into the car air conditioning.
9, a few minutes later, when you feel that the refrigerant bottles are not cold, that added finished, if the pressure gauge shows still not up to supplement the standard, then add a bottle, until the pressure meter display standard, my car total two bottles (standard gauge attached).
Filling after the completion of the work, immediately tried the air conditioning, really good, and before the cool feeling, is really "fonder"!
The detection of the pipe is left the bottle, middle refrigeration pressure gauge, the right side is the automobile air conditioning low pressure quick connector.
Automotive air conditioning refrigerantDIYSupplementary filling method
Automotive air conditioning refrigerant, and tire gas as convenient and safe.
Automotive air conditioning in general will each year about 10% of the loss of normal refrigerant, which is due to automobile air conditioning compressor sealing mode decision (automotive air conditioning compressor is half sealed). As long as we regularly to automotive air conditioning refrigerant can be added to detect. Don't need to worry about the use of methods, I tell you you friends DIY automotive air conditioning detection method. Friends can try it yourself with refrigerant.
The method is as follows:
1. need to prepare a car air conditioning DIY detection tube.
With R134A refrigerant 2. a bottle of car.
3. now to the car testing pressure: first DIY tube opener end of the thimble anti clockwise rotation to the top of the bottle opener, the refrigerant is screwed into the screw.
4. identify the low voltage interface in general under the hood of the left side has a blue or black hat, hat there is a L word, the small cap is screwed down.
5. will the car engine starting and open air blower AC switch, open to the maximum, run and wait for three minutes. Connect the DIY tube interface to the low voltage end of the automobile air conditioner.
After the 6.DIY tube is connected to the low voltage interface, the DIY tube pressure gauge will instantly be calibrated. At this time, the pressure gauge on the DIY pipe is consistent with the air conditioning system pressure, see the pressure gauge on the pressure gauge, you know the pressure in the system. How much pressure do you need to add the refrigerant? Then there is a knowledge note! The pressure in the automotive air conditioning system varies according to the ambient temperature. As shown in the chart below, the temperature and the pressure of the air conditioning system confirm that the pressure is high and low in the system, the system pressure is higher, indicating that the refrigerant in the system is more than the normal value, otherwise, it is necessary to add refrigerant. If the ambient temperature is 30 degrees, the pressure in the air conditioning system should be about 45PSI, and the refrigerant should be supplied less than 45PSI. Fahrenheit is a common temperature unit in the United States, thank you
The pressure of the low pressure meter in the external environment (Fahrenheit temperature), the value of the following pressure gauge is the theoretical constant temperature value in the laboratory, and the outdoor temperature can not meet this requirement in the process of using. So the owners of friends please press chart in numerical minimum calculation in the use process, calculation method is the minimum value to the minimum value minus 10PSI calculation is normal pressure system, the pressure must not exceed the minimum pressure, more than once, the opportunity to reduce automatic protection, then it will be very poor cooling effect! When the external temperature is 30 degrees, the chart shows 45PSI-55PSI, which is the constant temperature value. When we calculate, we should subtract the 10PSI pressure by 45PSI, and the result is 35PSI. This is the normal pressure value of the system. It is better not to exceed this value.
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. low pressure air conditioning system, the need to add refrigerant, the bottle opener in the thimble clockwise, pierce the refrigerant bottle, bottle opener in the thimble immediately counter clockwise to the top, (Note: this time scale pressure gauge will show up to 100PSI to 110PSI, the scale pressure gauge 2 seconds after the time will slowly drop down. Dial back to its original display, this is normal, because the bottle is punctured, the pressure, a few seconds it shows the R134A bottle of the pressure in the bottle pressure by the compressor after absorption is shown as the pressure in the system!) Shake the refrigerant bottle, the refrigerant gas will flow into the system at the same time, see the pressure gauge, and the temperature and pressure of PSI units to be. Note: the refrigerant bottle should not be upside down!!! (except for oil mixtures)
Note: in the absence of pierce the refrigerant bottle, DIY tube has a little air, if the owner to need to drain a little air in the pipe, please according to the following method, in the absence of refrigerant bottles will pierce the refrigerant bottle opener and gently loosen a bit, then the DIY pipe in the air will be air conditioning system in the refrigerant to go out, then tighten the refrigerant bottle!!!
8. observe the pressure gauge calibration is normal, please immediately the bottle opener in the clockwise rotation to the bottom and tighten, remove the air conditioning system low port connector can. If one bottle is not enough, add second bottles of refrigerant according to the method described above, until the outside temperature and system pressure are up to one day.
9. at this time, the car air conditioning system refrigerant supplement to complete, please L small cap tightening.
Note: the above pressure calibration and filling method are the filling instructions of ID and EF of American refrigerant sales company. After completing a successful filling, it will feel as convenient as the car tire flushing!
Features and uses
(1) R134a as the most widely used medium and low temperature environmental protection refrigerant, because of its good comprehensive performance, HFC-134a has become a very effective and safe alternative to CFC-12.
(2) including mainly used in in most areas, the use of R12 refrigerant, refrigeration equipment, refrigerators and freezers, water machine, automobile air conditioning, central air-conditioning, dehumidifier, commercial refrigeration, cold storage, ice machine, ice cream machine, refrigeration condensing units, but also can be applied to aerosol propellant, medical aerosol, insecticide drug propellant, polymer (plastic) physical foaming agent, and magnesium alloy protective gas etc..
(3) HFC-134a does not contain chlorine atoms, not destructive to the ozone layer, has good safety performance (no inflammable, explosive, toxic, non irritating, non corrosive); the cooling capacity and efficiency and CFC-12 is very close, so regarded as excellent long-term alternative refrigerants.
(4) HFC-134a can be widely used as refrigerant for automobile air conditioner, refrigerator, central air conditioner, commercial refrigeration and so on, and can be used in medicine, pesticide, cosmetics and cleaning industry.
(5) the chemical stability of R134a is very good, but because of its water solubility is higher than R22, so the refrigeration system is unfavorable, even a small amount of moisture exists in lubricating oil, will produce acid, carbon dioxide or carbon monoxide, has a corrosive action on metals, or produce "copper" role so the R134a of the system requires higher dry and clean. The chemical reaction of steel, iron, copper, aluminum and other metals was not found by R134a, but only slight effect on zinc.
