Here is a link to a site that explains the concept of how to read a chart. Their example is using R404A; however, the basic principles of reading a PH chart are the same. Assuming you have a R134A chart, you need only apply the principles to your chart.

Another site that may be helpful. This one is using a 134A chart for their example.

Is there any difference between the plain auto R134a and R134a used in the 2000 year Kenmore refrigerator model 596.58642890? If it is different where can I buy a small can of appliance grade R134a ?


r134a gas is r134a gas and it is used in a variety of applications
because it is a extreme high pressure gas , it is unlikely that you will get a small can of it
It will be cheaper to have a fridge technician come and use the right amount as it normally comes in a 9 kg bottle and cost plenty
a fridge may use 100 grms if lucky

What is wrong with the aircondition,when you start the car the compressor woks fine for aminute then shuts off


It is probably low on refrigerant. Most 1994 and newer use R134A (new stuff) 1993 and older mostly use the old R12 which you cannot buy unless a certified AC technician. You can add R134A yourself after purchasing a can WITH a gauge on it, reading the directions well first, about $35.

How much R134a should I add to 2000 toyota? My a/c wont charge


Not sure I understand. R134a is the refrigerant. So what else are you adding? The best solution is to find the leak and repair it. Leaks will continually become worse. Your system may not hold anything anymore. However having to much refrigerant will overcharge the system and not allow it to cool. All systems hold different amounts, there should be a sticker under the hood that tells you how many pounds the system holds.

What is the refrigerant use in xj6 jaguar 1995


If it has screw on fittings then r12. If the fittings are quick disconnect type then it takes r134a. I would do a r134a system conversion if needed because of the availability and price of the r134a refrigerant.

Automotive r134a refrigerant in refrigerator compressor?


it is the same refrigerant however the car industry and the refrigeration industries purity standards ARE NOT the same!! as a rule refrigerant manufactured under the refer standard can be used for auto but not the reverse, you can use it but be forewarned chances are you will be replacing the compressor due to an electrical burn out

Have a cold point BF 368 refrigerant R134a, the bulb inside the u


refrigerant r134a is the type of freon in the unit, not a model #. probably the wrong type bulb. you can't put a regular bulb in it. it has to be an appliance bulb. they have a thick coating on it to endure extreme temps.
