Fundamentals of Refrigeration
Manuel Calzada, P.E.
Overview
This
course covers the fundamentals and the principles of the single compression
refrigeration cycle. It includes the thermodynamic properties of the
refrigerants and basic calculations used to determine capacities of each one of
the components in the single stage refrigeration cycle.
Only
basic knowledge of thermodynamics is needed to understand the Pressure to
Enthalpy diagrams and energy conservation equations.
The course is divided into
sections to study each one of the basic components (compressor, condenser,
expansion and evaporator). At the end, a section is included to cover the
complete refrigeration cycle. The purpose of this section is to show the
student how changes in one of the components can affect the overall performance
of the complete cycle. This section is especially important because, although
each component is selected individually, it is important to understand how
variations in any of the components can affect the overall performance of the
complete system.
The
student must take a multiple-choice quiz consisting of ten (10) questions at
the end of this course to obtain PDH credits.
