RAC 40 QUIZ 3 REVIEW | QUESTIONS AND ANSWERS |
2026 UPDATE | RATED 100% CORRECT
The _____ compressor is another positive displacement compressor and is
used for larger air conditioning and refrigeration applications. Answer - Screw
Compressor
The four (4) major components of a vapor compression refrigeration system
are the compressor, condenser, evaporator, and ________ ______. Answer -
Metering device
The amount of heat a refrigerant contains with -40F as the 0 heat content
reference point is called Answer - Enthalpy
From a performance standpoint, a substitute for R-12 is Answer - R-134A
The ___________ __________ is referred to as a kinetic displacement
compressor. Answer - Centrifugal Compressor
The refrigerant vapor picks up additional heat as it flows from the evaporator
to the compressor. The heat is picked up from the Answer - Suction line
What is the purpose of the metering device? Answer - Meters the flow of
refrigerant entering the evaporator, reduces the boiling point to create a
pressure/temperature drop
, When the refrigerant leaves the metering device, it is not 100% liquid. Why?
Answer - Because flash gas occurs and causes the 100% liquid to turn into 25%
vapor and 75% liquid.
Rejects both sensible and latent heat from the refrigeration system. Answer -
Condenser
Abort heat from the system Answer - Evaporator
Is the heart of the refrigeration system Answer - Compressor
A valve or small fixed-size tubing or orifice that meters liquid refrigerant into
the evaporator Answer - Metering device
R-502 Answer - Orchid
R-12 Answer - White
R-717 Answer - Silver
R-11 Answer - Orange
R-114 Answer - Dark Blue
R-134a Answer - Light Blue
