Refrigeration TWO
A deep dive into the science behind AC/R systems.
Course Summary
Refrigeration TWO is the second of a 4-part series. A continuation and expansion of Refrigeration ONE.
Refrigeration TWO is where we take a deep dive into the science behind our systems. This course pulls a technician into the technologist's or engineer's world ever so slightly.
To put it bluntly, if you don't know how the system works, what the hell do you know?
Who is this for?
Just like the concepts carry from the smallest of systems to the largest, so does the science.
This course is meant for intermediate to advanced students.
If you have completed Refrigeraton ONE, this is where you should be headed next!
If you're part way through an apprenticeship, the science behind the systems should help with your hands on learning.
If you've been in the industry for a long time, but have never had formal training, a lot of this should be easy for you to get into but at the same time be brand new.
What is covered?
System Science
Pressure Enthalpy? Btu/Lb? Net Refrigeration Effect? Coefficient of Performance? And many other terms that impact every single system that we work on.
Introduction to heat pumps, system accessories, and packaged vs split systems
Psychrometrics: Plotting the system process
Refrigerant Pipe Sizing
Troubleshooting
Have a look at the below lessons for details!
This is a college level course which spans about 28 hours in a classroom.
10 Separate lessons, lecture style, and running approximately 7 hours total.
Quizzes and tests throughout to ensure your progress. (10-15 hours)
+ Q & A
+ Community
+ Live Chat
Not only did your classes, but also your mentorship really changed my life. Thank you sir.

Love how all the slides are neat and organized. Also love how the slides are easy to follow when taking notes and how Dan makes everything as simplistic as possible
Miguel Felato Rodriguez
Best online course for HVAC
This online HVAC program is the best program I have found online and is worth every penny, Dan is a great teacher and breaks everything down very well. Will totally recommend.
