The refrigeration cycle has been critical in developing coolant systems and freezer/refrigeration units over the last 100 years. Industrial and commercial refrigeration rely on this cycle to prolong the life of food products, safely store chemicals and pharmaceuticals, and aid in distributing temperature-sensitive items.

The Introduction to Industrial and Commercial Refrigeration training course explains the purpose and function of industrial and commercial refrigeration. It also discusses how heat transfer and the refrigeration cycle drive the process. It describes the components and refrigerants that may be used in these units. This online training course includes:

• Refrigeration purpose
• Functions and industries
• Heat transfer
• The basic refrigeration cycle
• Industrial/commercial refrigeration components
• Refrigerants

Introduction to Industrial and Commercial Refrigeration is part of the Heating & Cooling Fundamentals training series.
