Refrigerants and Refrigeration
systems) with Complete Solutions
high-pressure appliance - ANSWER - A refrigeration or air conditioning system that
has a refrigerant charge over 5 lb, has a boiling point between -58°F and 50°F at
atmospheric pressure, and is not categorized as low-pressure.
low-loss fitting - ANSWER - A fitting used to prevent the release of refrigerant from a
system to the atmosphere and to prevent air from entering the system.
refrigerant recovery - ANSWER - A process that allows refrigerant to be removed
from a system in any condition and stored in an external container without
necessarily testing or processing it in any way.
service practice - ANSWER - A procedure created by the EPA and used by
technicians who service and dispose of refrigeration and air conditioning equipment
for the reduction of refrigerant emissions.
refrigerant reclaiming - ANSWER - A process that allows used refrigerant to be
conditioned to new product specifications by means that may include distillation.
equipment and reclaimer certification - ANSWER - A credential required by the EPA
that contractors and/or technicians must acquire for their particular recovery and/or
recycling equipment before use.
refrigerant recycling - ANSWER - A process that allows refrigerant to be cleaned by
separation with single- or multiple-pass devices, such as replaceable-core filter-
driers, which reduce moisture, acidity, and particulate matter.
low-pressure appliance - ANSWER - A system that uses a refrigerant that boils above
50°F at atmospheric pressure and operates at low pressures.
