3. Thermodynamics and Refrigeration:
Simplified
Refrigeration is based on heat transferring from a
low-temperature region to a high temperature
region. To accomplish this, a refrigerator has four
main parts: a compressor, condenser, expansion
valve, and evaporator that work together like this:
4. Thermodynamics and Refrigeration:
Simplified
1. The compressor, powered by electricity, (when
you plug your refrigerator in) compresses the
refrigerant gas. This gas expands and moves to the
condenser (coils) as a super-heated vapor.

3. The expansion valve regulates the pressurized
refrigerant as it enters the evaporator. This sharp
change in pressure causes the refrigerant to
immediately boil and evaporate, taking heat from
the surrounding evaporator.
