Refrigeration Systems

The refrigeration section of the ice machine is complicated. Therefore, servicing and most maintenance tasks must be undertaken by the adequately equipped and trained technician. This course covers refrigeration section components with a high-level overview, giving the reader a basic understanding of the purpose of the components.

The refrigeration system of the ice machine is complicated. Therefore, servicing and most maintenance tasks must be undertaken by the adequately equipped and trained technician.

This course covers refrigeration section components with a high-level overview, giving the reader a basic understanding of the purpose of the components.

This book and course address ice machines explicitly using the direct expansion (DX) refrigeration cycle. The basics of this type of system are simple in the hands of a technician properly trained and equipped. The major components of the DX system are the compressor, the evaporator, the condenser, and the metering device. The metering device is considered the dividing point of the ‘high’ and ‘low’ sections of the refrigeration system.

Although other updated refrigerant variants exist as of this writing, those systems are intentionally not covered here because those systems require toxic and flammable refrigerant handling. Therefore, do not attempt to service ice machines built with R-717 or R-290 until trained to do so.

There are differences between components and controls.

  • Components are the significant parts that create the refrigeration cycle.
  • Controls manipulate the components of the refrigeration system.

Here are some topic areas covered in this course:

  • Understand the functions and operations of the important refrigeration system components.
  • Understand how each component fits into the refrigeration circuitry, and it’s impact on the sequence of operation.
  • Understand the variables in the implementation of certain controls, depending on the manufacturer and model of machine.

This course compounds the information and topics that you’ve learned in previous chapters and resources up to this point. In other words, you could need the information learned in previous resources to complete this section.
