Front
What does the compressor do in a vapor-compression system?
Back
The compressor raises the refrigerant vapor’s pressure and temperature.
03
Front
What does EPA Type I certification cover?
Back
Type I certification covers technicians who service small appliances. Work that can compromise the refrigerant circuit generally requires the appropriate Section 608 certification.
04
Front
What recovery percentage applies to equipment made before November 15, 1993?
Back
With recovery equipment made before November 15, 1993, recover 80% of the refrigerant.
05
Front
What must technicians never do with refrigerant during service or disposal?
Back
Do not intentionally vent refrigerant during service or disposal.
06
Front
What should you do before electrical work on an appliance?
Back
Disconnect power before electrical work, verify that it is off, and use appropriate eye and hand protection.
07
Front
What happens to refrigerant in the condenser?
Back
The condenser releases heat as the refrigerant condenses into a liquid.
08
Front
What is the metering device’s role?
Back
A capillary tube or other metering device reduces the refrigerant’s pressure.
09
Front
What happens in the evaporator?
Back
The evaporator absorbs heat as the refrigerant boils back into vapor.
10
Front
What does a filter-drier help remove?
Back
A filter-drier helps remove moisture and contaminants from the refrigeration circuit.
11
Front
What recovery percentage applies to newer equipment when the compressor works?
Back
With equipment made on or after November 15, 1993, recover 90% if the appliance compressor works.
12
Front
What recovery percentage applies to newer equipment when the compressor does not work?
Back
With equipment made on or after November 15, 1993, recover 80% if the appliance compressor does not work.
