R134A Air Conditioning Refrigeration Recover/Vacuum And Recharge Machine With Online Support
Why Recover & Recycle Refrigerant?
The Environmental Protection Agency does not want technicians venting refrigerant when servicing vehicles. For many years, this was a common practice because refrigerant was relatively cheap and no one realized it was causing any harm. Today, R-12 is scarce and expensive, and we know it is harmful to the ozone layer.
Reducing global warming was the logic behind not venting R-134a. Although R-134a contains no chlorine and poses no danger to the ozone layer, it is a "greenhouse" gas that retains heat and contributes to the global warming problem. The "Global Warming Potential" (GWP) rating of R-134a is 1,200, which compares to 7,300 for R-12, but only 1.0 for carbon dioxide. So every pound of refrigerant that leaks or escapes into the atmosphere has the same effect as thousands of pounds of CO2. So although recovery is apparently no longer necessary, it is recommended.

Refrigerant Recovery Procedure
Using a recovery/recycling machine is not difficult. The basic
procedure goes as follows:
1. Connect the hoses on the recovery machine to the service fitting
on the vehicle.
2. Turn the recovery unit on following the equipment manufacturer's
operating instructions. Allow the machine to continue pulling
refrigerant from the system until it indicates all of the
refrigerant has been recovered (system pressure reads vacuum and
holds vacuum for at least 5 minutes). If the machine does not have
an automatic timer or shut-off, discontinue recovery at this time,
and close and disconnect the service hoses.
TIP: If A/C components show evidence of icing during the recovery
process, the components can be gently heated to speed up the flow
of refrigerant. Use a hot air blow dryer, never any type of open
flame, to heat parts.
3. Once the recovery process is complete, determine how much oil
was pulled out along with the refrigerant so you can replace it
when the system is recharged. Most machines have an oil cup that
will show how much oil was taken out. The cup should usually have
about one ounce of oil in it if the system contains the proper
amount of oil. If the system is low on oil, there may be little or
no oil in the cup. On the other hand, if the system is overcharged
with oil, there may be several ounces of oil in the cup.
4. After the refrigerant has been recovered, the recycling process
can begin. The time it takes to clean the refrigerant can vary from
20 minutes up to an hour depending on the amount of contamination.
During the recycling phase, the refrigerant is filtered and dried.
Particulates, moisture, oil and air are all removed until the
refrigerant meets purity standards. A moisture indicator light
usually signals when the job is done. The refrigerant can then be
put back into the vehicle, or saved and reused in another vehicle.
Most machines use "single-pass" recycling where the refrigerant
makes only one pass through the cleaning circuit, but some machines
also offer "multi-pass" recycling or a choice of single-pass or
multi-pass cleaning. Multi-pass cleaning takes longer but may be
necessary with refrigerant that contains a lot of moisture.
The filter-drier that removes particulates and moisture from the
refrigerant needs to be replaced periodically. Filter capacities
vary somewhat from one machine to another, and lifespan depends on
how much crud and moisture the filter picks up from the
refrigerant. But as a rule, a typical filter will usually clean
about 1,000 lbs. of refrigerant before it has to be replaced.
