EPA Exam Version D34
A purchaser has an business manner refrigeration gadget that includes one thousand lbs. Of
R-22 that has passed the applicable leak charge threshold. How often is the patron required to
perform a leak inspection? - ANS-each three months
A refrigerant label is located on a; - ANS-cylinder to pick out gross weight
After installation of a field piped cut up system, the unit need to first be pressurized with; -
ANS-Nitrogen and leak checked
After refrigerant liquid has been recovered from the equipment, any last vapor is; -
ANS-removed through the recuperation device
Before making a first-rate repair, technicians must evacuate an equipment or element containing
extra than 200 pounds of R-410A to which of the subsequent ranges? - ANS-10 inches of Hg
vacuum
During evacuation with massive amounts of moisture it could be vital to growth pressure to
counteract freezing with gas which include; - ANS-Nitrogen
For what refrigerant is an device room refrigerant detector NOT required below ASHRAE
Standard 15 furnished the mechanical air flow gadget in the equipment is run continuously? -
ANS-R-717
HCFC refrigerants incorporate which of the following - ANS-hydrogen, chlorine, fluorine, and
carbon
How can you accelerate the removal of the refrigerant price from a gadget? - ANS-Cooling the
healing cylinder to lower its pressure
how do the worldwide warming potentials of isobutane (R-600a), propane (R-290_ and R-441A
examine to the GWPs of HFC-134a, R-404A and R-410A? - ANS-they may be substantially
lower
how does the global warming potential of R-410A evaluate to carbon dioxide? - ANS-it's miles
thousands of times extra
How lengthy do proprietors or operators of an equipment with a full charge of 50 or greater
pounds of ozone-depleting refrigerant ought to retire an equipment if the substitute uses a
refrigerant that is exempt from the venting prohibition? - ANS-18 months
