This course is a continuation of HVAC/R Advanced Commercial and Industrial Service Practices and is designed to teach students hands-on skills for maintaining, monitoring, and managing residential and commercial grade walk-in refrigerators and freezers. A comprehensive study of commercial-grade ice makers such as flakers, cubers, and nugget-type units provides an intense experience with low-temperature refrigeration equipment, including various types of commercial refrigeration equipment, restaurant, and supermarket refrigeration systems. Students will be required to change out a compressor, service, and repair critically charged systems to enhance their overall understanding of mechanical and electrical troubleshooting. The course will examine various types of refrigeration components and their contribution to overall system performance and is designed to teach commercial piping, compressor selection, refrigeration system selection, applications, and installation techniques. These applications will include commercial refrigeration line sizing and troubleshooting. A variety of specialty tools related to equipment studied in this class will be introduced to round out the total experience.
