RETA INDUSTRIAL REFRIGERATION
CHAPTER 5 STUDY QUESTIONS WITH
ANSWERS
what is the purpose of the refrigeration compressor? - correct answer ✔✔ to draw Vapor away
from the evaporator at the same rate it is being generated in to raise the pressure of that Vapor
to a point where it can be condensed.
how does the refrigeration compressor maintain the temperature in the system evaporators? -
correct answer ✔✔ drawing out vaporized refrigerant at the rate to maintain the desired
evaporating pressure.
discharge paper from all compressors - correct answer ✔✔ will contain some level of superheat
the basic idea behind the design of the Hermetic compressor is to avoid - correct answer ✔✔
allowing refrigerant to escape to Atmosphere from Seals leaking
one reason discharge temperatures are lower on screw compressors then on reciprocating
compressors is because they - correct answer ✔✔ circulate large amounts of lubricating oil
through the compression chamber.
double acting reciprocating compressors. - correct answer ✔✔ compress Vapor on the fore
stroke and the backstroke
getting more pumping capacity out of a small reciprocating compressor versus older and larger
compressors was achieved by - correct answer ✔✔ increasing RPM and the number of
cylinders.
