refrigeration Questions with Answers (100%
Correct Answers)
The rate at which a refrigeration system will remove heat from the refrigerated
medium is defined as:
Coefficient of Performance
Net cooling coefficient
Refrigeration capacity
Compression Ratio
Differential efficiency Answer: Refrigeration capacity
Which of the following correctly describes the heat transfer that takes place in a
simple ice-box?
There is a net loss of heat from the system, as the air cools.
Air gives up sensible heat; ice does not gain any heat.
,2
Air gives up sensible heat; ice gains sensible heat.
Air gives up sensible heat; ice gains latent heat of fusion.
Air gives up latent heat; ice gains latent heat of condensation. Answer: Air
gives up sensible heat; ice gains latent heat of fusion.
