The Refrigeration Cycle PDF Print E-mail
The refrigerator in your kitchen uses a cycle that is continuous. In the following example, we will assume that the refrigerant being used is pure ammonia, which boils at -27 degrees F. This is what happens to keep the refrigerator cool:

  • The compressor compresses the ammonia gas. The compressed gas heats up as it is pressurized.
  • The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. The ammonia gas condenses into ammonia liquid at high pressure.
  • The high-pressure ammonia liquid flows through the expansion valve. You can think of the expansion valve as a small hole. On one side of the hole is high-pressure ammonia liquid. On the other side of the hole is a low-pressure area (because the compressor is sucking gas out of that side).
  • The liquid ammonia immediately boils and vaporizes, its temperature dropping to -27 F. This makes the inside of the refrigerator cold.
  • The cold ammonia gas is sucked up by the compressor, and the cycle repeats.
