| Modern refrigeration has many applications,
such as preserving medicine, blood, and the most important
application, the preservation of food. Most foods kept at
room temperature spoil rapidly. This is due to the rapid growth
of bacteria. Refrigeration preserves food by keeping it cold,
which greatly slows down the growth of bacteria. In days past,
blocks of ice were used in iceboxes to refrigerate food and
other items. These iceboxes were small and not very practical.
Today, mechanical refrigeration systems make transportation,
storage, and use of refrigerated goods easy and practical.
The installation, operation, adjustment, and repair of
refrigeration equipment are the primary responsibility of
the refrigeration technician. To perform these duties required
of a refrigeration technician, you need to understand the
principles and theory of refrigeration and recognize system
components and understand the way they work within the system.
This course also covers methods of installing, maintaining,
and repairing refrigeration equipment and maintaining, servicing,
and repairing domestic refrigerators and freezers. |
