Commercial Refrigeration Training Program

The Online Refrigeration Training Program is an advanced program, perfect for HVACR technicians and contractors who want to better understand refrigeration systems used in commercial applications like stores, warehouses, restaurants, and product and food services.

The online refrigeration training begins with the Fundamentals of Refrigeration with Chris Compton and moves into the advanced courses with Dick Wirz. The first time the 441 and 442 courses were offered in a webinar, Dick’s lectures were recorded. Those recordings are included in the asynchronous delivery so you feel like you’re sitting in his classroom. He covers everything you need from refrigeration principles through evaporators, condensers, compressors, metering devices, controls, accessories, motors, and the various refrigerants used so you can service walk-in refrigerators and freezers, and commercial ice makers with confidence. He also describes the most common service issues and troubleshooting procedures.

141 HVACR Refrigeration I Course

(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. This online refrigeration training course is recognized for 18 hours of continuing education (CEHs) applicable to NATE re-certification.

Modules Cover

Basic Refrigeration Cycle Physics
Condensation and Condensers

441 HVACR Commercial Refrigeration I Course

(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. Recommended Prerequisites: you will need a strong working knowledge of HVACR Fundamentals prior to enrollment into this course. This online refrigeration training course is recognized for 24 hours of continuing education (CEHs) applicable to NATE re-certification. Required Text: Commercial Refrigeration for HVACR Technicians – by Dick Wirz.

442 HVACR Commercial Refrigeration II Course

(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. Recommended Prerequisites: you will need a strong working knowledge of HVACR Fundamentals prior to enrollment into this course. This online refrigeration training course is recognized for 18 hours of continuing education (CEHs) applicable to NATE re-certification. Required Text: Commercial Refrigeration for HVACR Technicians – by Dick Wirz.

Modules Cover

Compressor Motor Controls
Retrofitting, Recovery, Evacuation, and Charging
Supermarket Refrigeration
Walk-in Refrigerators and Freezers
Ice Machines
Product Temperatures for Preservation and Health – Refrigeration Business Tips

Enrollment Details

Required Textbook
Commercial Refrigeration for Air Conditioning Technicians
(shipped upon enrollment, included in the program price).

Prerequisites
This advanced commercial refrigeration training course is designed for HVACR technicians and contractors, facilities managers, and commercial maintenance technicians who have already completed an educational program for HVACR and/or have current working knowledge of HVACR fundamentals. It will build on your existing knowledge.

245 HVACR Compressor Failure Analysis w/ Bob Feathers
This is a 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

Prerequisites
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. This online refrigeration training course is recognized for 5 hours of continuing education (CEHs) applicable to NATE re-certification.

Grades

Students who complete a course with a grade of 70% or higher will receive a certificate of completion for that course. Further, at the end of the program, if both courses are passed with a score of 70% or higher, students will receive a Certificate of Completion for the HVACR Commercial Refrigeration Program. Both courses in the program also carry NATE continuing education credit for technicians maintaining industry certifications.
