Description

If you are an HVAC or refrigeration service professional, this course is for you. In this training course students will learn:

  • The four key components of ALL refrigeration systems
  • Introduction to the refrigeration cycle
  • Equipment needed to perform refrigeration system diagnostics. Bonus, devices what you need an what you don't.
  • Understanding the temperature relationship chart
  • What is superheat and subcooling and how to acquire readings from a refrigeration system
  • How to use superheat and subcooling to perforn diagnosis on any refrigeration system
  • Bonus content: Industry update on the HVACR industry opportunities. 

How can your benefit from this class you ask?  Over my career, I have had the opportunity to teach some of the best and brightest the above key principals. With these principals, and the ability to refer back to this information as much as you want, there is NO refrigeration system you will not be able to fix. Many if my students have moved on to start their own HVACR business and earn their way into the SIX FIGURES through hard work and applying the principals in this class. YOUR ARE WORTH THE INVESTMENT!

Who is the target audience?
  • HVAC or Refrigeration technicians who work in the industry or are (Hopefully) considering entering the industry.

Foundation Section - The WONDER of refrigeration
3 Lectures 11:13

Foundation Lecture: Understanding the four key components of the refrigeration system, and how these components interact with one another in the refrigeration cycle is an essential step to both basic and advanced diagnostics. 

Preview 02:01

Foundation Lecture: Now that you can identify the four key refrigeration components, its time to dig deeper into the wonder of the refrigeration cycle.

Your toolbox - Must have tools for refrigeration system troubleshooting
3 Lectures 14:07

The relationship between refrigerant pressure and temperature is a core data point with performing diagnostics on any refrigeration system. This lecture demonstrates how to read and interpret a Temperature/Pressure chart that we will use in the following lessons. 

Introduction to the temperature pressure relationship chart
04:52

In order to diagnose problems in a refrigeration system, the technician must be able to accurately measure operating pressures. This lecture provides the technician with solid basics on the types of pressure measurements systems available. 

The manifold gauge set - Pressure measurement
03:19

As with reading pressure (in Lecture #4) reading temperature accurately also very important. This lesson provides the technician on information the type of temperature measurement system needed to perform refrigeration system diagnostics.  

Thermometer - Temperature measurement

Diagnostics Introduction - Key things your must know.
5 Lectures 24:27

Now with you have a basic understanding of the key refrigeration system components, the refrigeration cycle, the relationship between refrigerant pressure/temperature and the tools you need, its time to start the process of learning solid refrigeration diagnostic skills. 

Introduction - The second law of thermodynamics
07:01

Similar to the human body, you can't see inside of a refrigeration system. You can however take specific readings such as Super Heat to determine performance issues within the refrigeration cycle. Super Heat calculations demonstrated in this lesson will  focuse on the evaporator (or heat absorption) side of the refrigeration cycle. 

Introduction - Superheat (SH)

I am an industry-leading refrigeration systems designer, author, US Patent holder, business owner and consultant in HVACR.  I have developed a new line of high-efficiency process chillers that can reduce cooling system costs for MRI,CT,PET and LINAC systems up 60%. Legacy Chiller Systems is also in the process of integrating predictive services capable of reducing life cycle costs up to 30%. My talent for reducing HVACR and facilities engineering costs, implementing innovative energy conservation practices, and maximizing the efficient use of facilities and critical building systems for Hewlett Packard, Intel, IBM, eBay, and leading Department of Defense agencies are just a few of the ways I have contributed positively to the HVACR industry. I have 30+ years of experience strategically developing, implementing, and positively influencing commercial and industrial HVACR operations and manufacturing, installing, and servicing a line of process fluid chillers for industrial businesses, government agencies, and Fortune 500 corporate accounts.
