2. What is refrigeration system?
 Refrigeration is a process of removing heat from a low-
temperature reservoir and transferring it to a high-
temperature reservoir. The work of heat transfer is
traditionally driven by mechanical means, but can also be
driven by heat, magnetism, electricity, laser, or other means.

4. How refrigeration can work?
 Refrigerant flows through the compressor, which raises the
pressure of the refrigerant. Next the refrigerant flows
through the condenser, where it condenses from vapor form
to liquid form, giving off heat in the process. The heat given
off is what makes the condenser "hot to the touch.

5. Development of refrigeration through
ages
 Many of the conveniences we enjoy in our homes are the result
of years of innovation by dedicated inventors. Though we take
many of them for granted, some—like the refrigerator—have
hugely affected the way we live our lives. Who invented the
refrigerator, and how has it devolved over time

7. Electric Refrigeration
Albert Einstein is remembered for many scientific achievements, but, as Time
magazine notes, it’s often overlooked that he also made great contributions to eco-
friendly refrigeration. In 1930, Einstein and a colleague patented a refrigerator that
cools with ammonia, butane and water instead of Freon, a contributor to global
warming.
Although Einstein’s original refrigerator was not very energy efficient, researchers
from Oxford have adjusted his plans and believe they have a version that could be
competitive in the marketplace in the future.
