CFC CORE 2026 EXAMS SET QUESTIONS AND ANSWERS
RATED A+
✔✔Glycols and esters are refrigerant lubricants used with - ✔✔HFC based refrigerants
✔✔Glycol lubricants are hygroscopic, meaning - ✔✔they absorb water.
✔✔Glycol lubricants cannot be retrofitted - ✔✔...
✔✔An ester lubricants is a second generation lubricant widely used with - ✔✔HFC
based refrigerants.
✔✔Ester lubricants cannot be mixed with any other lubricant - ✔✔...
✔✔Mineral oil is used to lubricate - ✔✔CFC refrigerants
✔✔The ozone layer is located in the stratosphere at approximately __ miles above the
earths surface. - ✔✔28 (stratosphere - 8-30 miles)
✔✔Chlorine and bromine - ✔✔deplete the ozone layer
✔✔One chlorine atom can destroy over ________ ozone molecules before finally being
removed from the stratosphere - ✔✔100,000
✔✔UV radiation has been linked to - ✔✔skin cancer, cataracts, damage to materials
like plastics, and harm to crops and marine organisms.
✔✔Chlorine monoxide found in the upper stratosphere is another indication that the
ozone layer is being destroyed. - ✔✔...
✔✔September 16, 1987 - ✔✔US and 22 other countries signed the Montreal Protocol.
The protocol is an international evironmental agreement that establishes requirements
to phase out ozone-depleting CFC substances.
✔✔Excise tax on the sale of CFCs - ✔✔...
✔✔November 15, 1990 - ✔✔Clean Air Act Amendments (CAA) signed.
✔✔July 1, 1992 - ✔✔Section 608 of the CAA prohibits knowingly venting CFC and
HCFC into the atmosphere
✔✔EPA Type 1 certification - ✔✔Small appliances
, ✔✔EPA type 2 cert - ✔✔high pressure/very-high pressure appliances
✔✔EPA type 3 cert - ✔✔Low pressure appliances
✔✔EPA universal - ✔✔All types of equipment
✔✔November 14, 1994 - ✔✔The sale of refrigerants in any size container is restricted
to certified technicians.
✔✔Recovery - ✔✔The removal of refrigerant in any condition from a system without
testing or processing the refrigerant.
✔✔Passive recovery method - ✔✔used with appliances designed to use 15lb or less of
refrigerant
✔✔Active recovery - ✔✔Recovery process using a self-contained recovery unit. The
recovery unit removes the refrigerant with no assistance from system components
✔✔Recycling - ✔✔The removal of refrigerant from a system and cleaning the refrigerant
for reuse. Typically implemented at the job site, and do not require the refrigerant to be
tested.
✔✔Recycled refrigerant is refrigerant that has been processed using - ✔✔oil separators
and single or multiple-pass filter/dryers to separate moisture, acidity, and particulate
matter from the refrigerant.
✔✔Reclaiming - ✔✔the reprocessing of used refrigerant to meet new refrigerant
standards. Reclaimed refrigerant must be processed to the purity specifications and
verified using laboratoy analysis.
✔✔It is important not to mix different refrigrants in the same container because most
refrigerant mixtures are impossible to reclaim - ✔✔...
✔✔Low-Loss fittings automatically trap refrigerant in a hose when disconnected and are
required on all recovery, recycling, and reclaiming equipment. - ✔✔...
✔✔Nov 15, 1993 - ✔✔Recovery equipment manufactured on or after nov 15 1995 must
be tested by an EPA-approved testing org.
✔✔Equipment manufactured before nov 15 1993 / compressor not operating - ✔✔80%
recovery required
✔✔Equipment manufactured after nov 15 1993 / compressor operating - ✔✔90%
recovery required
