Refrigeration technicians who violate the Clean Air Act Lose their EPA certification, be fined, be required to appear in Federal court.
can: -
After 1995, any supplies of CFC refrigerants to service recovery and recycling.
existing units in the USA can only come from: -
Refrigerant that is recovered can be returned to: - the same system or other systems owned by the same person without
restriction.
Refrigerant can not be called "reclaimed" unless it: - . has been chemically analyzed and the refrigerant meets the ARI-700 standard.
The EPA can require a technician to demonstrate their revocation of the technicians certification.
ability to perform proper procedures for recovering
and/or recycling refrigerant. Failure to demonstrate
competency can result in: -
, What characteristic(s) of CFCs make them more likely to Refrigerants that contain chlorine but not hydrogen are so stable that they do
reach the stratosphere than most other compounds not break down in the lower atmosphere after being released. The chlorine or
containing chlorine? - bromine reacts with the ozone, causing it to change back to oxygen, thus
destroying the ozone layer.
A system is considered dehydrated when: - the vacuum indicator shows you have reached and held the required finished
vacuum.
Disposable refrigerant containers are used for ______ virgin refrigerant
Which refrigerant is an HCFC? - R-123, R-124, R-22
What statement is true about an azeotropic refrigerant It is a mixture that acts like a single-component refrigerant over its entire range.
mixture? -
Chlorofluorocarbos (CFCs) and It is a mixture that acts like a single-component refrigerant over its entire range.
hydrochlorofluorocarbons (HCFCs) have which of the
following in common? -
To scrap a disposable cylinder, the internal cylinder 0 psig.
pressure should be reduced to at least: -
Manifold gauge sets are often color coded, when this is
done, the high pressure gauge is color coded: - Red.
In general, blended refrigerants should be charged: - as a liquid.
Blended refrigerants leak from a system: - in uneven amounts due to different vapor pressures.
Which of the following gases help form the earth's
protective shield? - Stratospheric Ozone
In a refrigerant system, the device that changes a low
pressure vapor to a high pressure vapor is the: -
compressor.
Data shows that chlorine in the stratosphere comes
mainly from CFCs rather than from natural sources such
as volcanoes because: - The rise in the amount of
chlorine in the stratosphere matches the rise in the
amount of fluorine, which has different natural sources
than chlorine; The rise in the amount of chlorine in the
stratosphere matches the rise in CFC emissions; Air
samples taken from the stratosphere over erupting
volcanoes show that volcanoes contribute a small
quantity of chlorine to the stratosphere when
compared to CFCs;
Which atom of the CFC molecule causes ozone
depletion? - chlorine
The ozone layer protects the earth from: - ultraviolet
radiation from the sun.
