Commercial Refrigeration Program

 The following courses are included in this course package:

141 HVACR Refrigeration I (18 hours / 60 days) - Advanced      Written by Chris Compton

HVACR Refrigeration 141 provides a thorough examination of the refrigeration cycle as it is applied to both air conditioning and refrigeration purposes, and presents a practical and systematic method to diagnose problems in the refrigeration cycle. If you understand the parameters governing the operation of the refrigeration cycle, you will be able to diagnose any piece of equipment. 

Prerequisite: It is recommended that you have a good understanding of HVACR Fundamentals, or have a working knowledge of them, prior to enrollment into this intermediate course. Instruction aligns with ACCA Quality Installation and  ACCA/ ASHRAE Standard 180.

142 HVACR Refrigeration II (18 hours / 60 days) - Advanced       Written by Chris Compton

This course is a continuation and elaboration of HVACR Refrigeration I. Presentations describe the application of common accessories found in a system, piping arrangements, sizing considerations and system operation. Instruction aligns with ACCA Quality Installation and ACCA/ ASHRAE Standard 180. 

Prerequisite: You will want to have completed 141 HVACR Refrigeration I, or have a working knowledge of the content of that course prior to enrollment into this advanced course. 

441 HVACR Commercial Refrigeration I (24 hours / 60 days) - Advanced       Written by Dick Wirz

We will compare things you’re already familiar with like space temperatures and common components of basic AC systems to those of commercial refrigeration systems. We will examine evaporators, condensers, compressors, metering devices, controls and accessories, and the refrigerants commonly used in commercial refrigeration. We will review the important terminology. At the end of this course we will cover some system troubleshooting, giving you a chance to put your knowledge to work on the 9 most common system problems. And you will understand when to apply TROT (The Rule Of Thumb) in the absence of a manufacturer’s recommendation. 

Prerequisite: You will need a strong working knowledge of HVACR Fundamentals prior to enrollment into this course. 

442 HVACR Commercial Refrigeration II (18 hours / 60 days) - Advanced       Written by Dick Wirz

This course is a continuation of 441 HVACR Commercial Refrigeration I. Again, we will compare things you’re already familiar with like basic AC systems to those of commercial refrigeration systems. We will examine compressor motor controls, retrofitting, recovery, evacuation, and charging; various supermarket refrigeration systems, walk-in refrigerators and freezers, and commercial ice machines so you can identify the components, their functions, and the refrigerants belonging with each application. After you have a good understanding of the equipment, we’ll explore appropriate temperatures for products kept in that equipment. And finally, you will understand when to apply TROT (The Rule Of Thumb) in the absence of a manufacturer’s recommendation. 

Prerequisite: You will need a strong working knowledge of HVACR Fundamentals prior to enrollment into this course.

245 HVACR Compressor Failure Analysis w/ Bob Feathers

This is an 11 video / 5 hour series of compressor tear downs performed by and commented on by Bob Feathers, also known as “Mr. Compressor”. He dissects a range of manufacturer’s reciprocating semi-hermetic commercial compressors that have failed and points out the clues that point to the reason for failure.

“A Compressor Doesn’t Fail, A System Fails”! – Chris Compton

Prerequisite:   Because of the advanced topics discussed in this video series, it is recommended that you complete the first four courses of the Commercial Refrigeration Program.
