RETA INDUSTRIAL REFRIGERATION CHAPTER 1 STUDY QUESTIONS
|| || || || || || ||
WITH ACCURATE DETAILED ANSWERS || || ||
what is the purpose of a refrigeration system? - ✔✔to maintain the temperature
|| || || || || || || || || || || ||
operators must keep refrigeration systems operating safely and efficiently. Which of the
|| || || || || || || || || || || ||
following best describes the area of required knowledge for this to be possible? - ✔✔basic
|| || || || || || || || || || || || || || ||
physical principles, interpretation of information from temperature and pressure gauges,
|| || || || || || || || || ||
basic operating principles.
|| ||
mechanical Refrigeration is a series of steps that - ✔✔moves heat energy from a space or
|| || || || || || || || || || || || || || || ||
object to an area where it can Do no harm
|| || || || || || || || ||
heat energy always flows - ✔✔from an object at a higher temperature to an object at a
|| || || || || || || || || || || || || || || || ||
lower temperature. ||
sensible heat - ✔✔is heat energy that causes a change in temperature but does not cause a
|| || || || || || || || || || || || || || || ||
change in state.
|| || ||
latent heat - ✔✔is heat energy that causes a change of state but does not cause a change
|| || || || || || || || || || || || || || || || || ||
in temperature.
||
which of the answers below is an example of heat transfer by convection? - ✔✔warm air
|| || || || || || || || || || || || || || || ||
rising and cold air falling.
|| || || ||
how does the refrigeration technician / operator know what the conditions are within a
|| || || || || || || || || || || || || ||
refrigeration system? - ✔✔by using his knowledge of system basic operating principles to
|| || || || || || || || || || || || ||
evaluate the temperature and pressure readings.
