There is a wide variety of commercial refrigeration equipment, from ice machines to supermarket food displays. Many refrigeration systems are old, operate inefficiently and have few if any equipment improvements. With today’s new refrigerants and technologies (such as floating head pressure, liquid sub-cooling and multiplexed compressors), there are many opportunities for improving the efficiency of existing equipment or for implementing new equipment.
Identify the components of a commercial refrigeration system
Describe the differences between conventional and parallel/multiplex refrigeration systems
List the factors that affect the heat-transfer efficiency of a condenser
Discuss the differences in air-cooled, water-cooled, and evaporative condensers
Identify the characteristics that affect the function of the evaporator
Discuss the variables to consider when evaluating and selecting a replacement refrigerant.
Assess ways to improve the energy efficiency of refrigeration systems.
Explain the benefits of subcooling.
Describe how floating head pressure and variable speed drives result in energy savings
Define the concept of IDSM and describe demand-side management strategies that can be used for commercial refrigeration
Identify relevant Title 24 Part 6 code triggers and mandatory measures
Identify relevant SDG&E programs that can help save energy and reduce costs
