Coke Machine Refrigeration / Cooling Tips
 

The basic refrigeration system in a Cola Machine works as follows

  1. The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization.
  2. As it cools, the refrigerant condenses into liquid form and flows through an expansion valve.
  3. When it flows through the expansion valve, the liquid refrigerant is allowed to move from a high-pressure zone to a low-pressure zone, so it expands and evaporates . In evaporating, it absorbs heat, making it cold.
  4. The coils inside the refrigerator allow the refrigerant to absorb heat, making the inside of the machine cold. The cycle then repeats.

The basic components are

  • A compressor
  • An expansion valve
  • A hot coil (on the outside)
  • A chilled coil (on the inside)
  • Two fans
  • A control unit
