11-1) List the different types of cooling mechanisms.
11-2) Which type of cooling mechanism is used in the most applications?
11-3) Briefly explain the fundamental principles that make the compression
refrigeration cycle work.
“Cold” is not a substance or an energy form, it is the lack of heat.

pressure side and a low pressure side?
11-9) What components are responsible for maintaining the high and low pressures
in a compression refrigeration system?
