EPA 608 9th edition
_________________________requires a refrigerant display to feel refrigerant leaks in order to
sound an alarm and automatically start a ventilation system in device rooms earlier than the
refrigerant
concentration reaches the TLV-TWA, - ANS-ASHRAE Standard 15
A "essential repair," in line with EPA guidelines, is described as any protection, provider or
repair involving the elimination of: (Give one part) - ANS-the compressor, the
condenser, the evaporator or an auxiliary warmth exchanger coil.
A centrifugal chiller's purge unit takes its suction from the pinnacle of the
____________________, separates air and different non-condensables from the refrigerant,
after which returns
the refrigerant again to the evaporator. - ANS-condenser
A leak-check ought to be achieved after each restore strive, and a comply with-up verification
leak-test need to be carried out within _______ days of the
restore - ANS-10
A low-strain appliance leaking above the leak price threshold must be repaired so that it
leaks underneath the threshold and the preliminary verification check conduct within
___________unless granted beyond regular time - ANS-30 days
A refrigerant reveal is needed for all __________________ refrigerant protection corporations.
Refrigerants are divided into corporations consistent with toxicity - ANS-ASHRAE
A refrigeration unit the use of an open compressor that has no longer been used in numerous
months is
in all likelihood to leak from the ___________________________. - ANS-rotating shaft seal.
A huge quantity of vapor will remain inside the equipment in spite of everything liquid is
eliminated. For
instance, an average 350 ton, R-123 chiller at zero psig nonetheless incorporates approximately
___________. Of
vapor - ANS-a hundred lbs
After restoration, refrigerant can be again to the appliance from which it become eliminated or to
some other appliance owned with the aid of the same individual without being recycled or
reclaimed. T/F - ANS-True
, All business and industrial process refrigeration (IPR) containing more than 50 lbs. Of
refrigerant MUST be repaired whilst the yearly leak rate is exceeds _________% - ANS-20
All records for leak inspections, preliminary verification, verification
assessments and statistics of recovered refrigerant from gadget with 5 to 50 lbs. Should be
stored
for ______ years by way of the owner or operator. - ANS-3
Always study the nameplate and search for labels connected to a device to help pick out
the_____________________ used and the overall charge. - ANS-type of refrigerant
Always assessment the ________________________ whilst working with any solvents,
chemicals, or
refrigerants. - ANS-Safety Data Sheets (SDS)
An equipment must be repaired inside ______ days whilst the once a year leak
rate exceeds 10% of the overall price. - ANS-30
An initial leak-test verification should be achieved inside ___________ of an appliance
exceeding the applicable leak rate - ANS-30 days
An ozone molecule carries; - ANS-Three oxygen atoms
Anyone that services, upkeep, or disposes of Type I, II or III equipment have to have
recuperation
device and/or recycling equipment that is licensed and categorised by means of an: -
ANS-EPA-permitted
system testing organization to meet EPA Standards
Appliances can be evacuated to atmospheric strain ____________ if leaks make recuperation
(evacuation) to the prescribed level unattainable. - ANS-0 PSIG
Appliances may be evacuated to atmospheric stress ( ______psig) if leaks make recovery
(evacuation) to the prescribed stage inconceivable - ANS-zero
As of ______________________, the sale of CFC and HCFC refrigerants is constrained to
certified
technicians. - ANS-November 14, 1994
As of ___________________, the sale of HFCs and HFOs also are restrained to certified
technicians. - ANS-January 1, 2018
