INDUSTRIAL REFRIGERATION (QUIZ 1) TEST QUESTIONS AND CORRECT
ANSWERS (NEW)
According to this text's first chapter, the basic function of a refrigeration system
is to: ANSWER Maintain a temperature
Refrigeration systems must be maintained by operators safely and effectively.
Which of the following best sums up the knowledge areas needed to make this
possible? ANSWER: Fundamental physics concepts, interpreting data from
pressure and temperature sensors. fundamental concepts of operation.
The process of mechanical refrigeration involves the following steps:
ANSWER transfers heat energy from a space or object to a location where it
cannot do harm.
Heat energy constantly moves from a hotter object to a colder one.
Sensible heat is defined as heat energy that modifies temperature but not state.
Heat energy that results in a change of condition but not a change in
temperature is known as latent heat.
Which of the following best describes convectional heat transfer? ANSWER :
Warm air passing over an object
How does the refrigeration technician/operator determine the state of the
refrigeration system? ANSWER : By analyzing temperature and pressure
readings utilizing his understanding of the fundamentals of system operation
