R-410A safety and training UPDATED
Exam Questions and CORRECT Answers
The Kyoto protocol that was established in 1997 calls - CORRECT ANSWER - for the
reduction of green house gases by an average of 5.23%
the development of the scroll compressor and the rapid adoption from the reciprocating
compressor has opened the door to new refrigerants and made our industry's challenge easier -
CORRECT ANSWER - the scroll compressor not only is more efficient; it also is able to
accommodate considerably higher pressures that are inherent in R-410A
in 2006 the U.S department of energy is scheduled to require that air conditioner efficiencies be
raised from - CORRECT ANSWER - 10 SEER (seasonal energy efficiency ratio) to 12
SEER or higher
the direct impact of R-410A is that it has a slightly higher global warming potential(GWP) than
R-22 - CORRECT ANSWER - the indirect impact of R-410A is that because of its
increased efficiency
R-410A systems use less energy - CORRECT ANSWER - thereby reducing carbon
dioxide emissions from power plants
the Federal Clean Air Act calls for the phase out of HCFC based R-22 with no production or
importing beginning in - CORRECT ANSWER - 2020
manufactures of air conditioning equipment must discontinue the use of HCFC based R-22 in
new equipment by - CORRECT ANSWER - January 1,2010
HFCs such as R-410A, R-134A are the refrigerants of choice for this generation - CORRECT
ANSWER - these refrigerants solve the initial problem of stratospheric ozone depletion,
but they still have some global warming potential
, regulations of the CAA prohibit venting of HFC refrigerants - CORRECT ANSWER - and
we can expect increased emphasis in the areas of the refrigerant containment and recycling of all
refrigerants
R-410A is a binary (two part) near-azeotropic mixture and is presently marketed under the brand
names of - CORRECT ANSWER - AZ-20 "puron" or "suva"
these newly manufactured R-410A air conditioning systems will require contractors and
technicians to - CORRECT ANSWER - shift to different tools, equipment and safety
standards when installing or changing out (retrofitting) older split A/C systems and repairing
systems in the field
we need to know that R-410A can only be used in equipment specifically designed and
constructed for R-410A - CORRECT ANSWER - R-22 systems cannot be retrofitted
without major component upgrades, to R-410A
R-410A operates at considerably higher pressures and why - CORRECT ANSWER -
special cylinders, gauges, and recovery equipment are necessary
R-410A utilizes polyol ester (poe) based oils and not mineral oil - CORRECT ANSWER -
we need to know how to properly install and service these systems that are not as forgiving
relative to moisture
R-410A operates at significantly higher pressures and refrigeration capacity - CORRECT
ANSWER - it is important to know why all refrigerant flow controls, feed devices, driers
and compressors are specifically designed for R-410A
refrigeration is defined as that branch of science which deals with the process of reducing and
maintaining the temperature of a space or materials below the temperature of the surroundings -
CORRECT ANSWER - to accomplish this, heat must be removed from the refrigerated
body and transferred to another body
