Refrigeration FOUR
Course Summary
Refrigeration FOUR is the fourth and final of a 4 part series.
Refrigeration FOUR is where we focus on a very different topic, equipment sizing and selection.
Who is this for?
This course is meant for anyone involved in the HVACR industry that may need to size, select, and install equipment. The sizing focuses on refrigerated food storage, but the principles are similar for most conditioned spaces.
This course is meant for advanced students, but it can also serve as a standalone course.
If you have completed Refrigeration THREE, this is where you should be headed next!
If you're nearing the end of an apprenticeship or possibly recently finished, the how's and why's behind equipment sizing will help you in a number of ways.
If you've been in the industry for a long time, but you're looking to perhaps move into equipment sales or consulting - you'll feel right at home while learning a new set of skills.
And lastly, if you have never worked in the industry, but you are jumping right into equipment sales or consulting - feel free to use this as a bit of a springboard in.
What is covered?
Refrigerated space load forms. (Hussman, Keeprite, Heatcraft)
Equipment sizing and selection.
Overview of different systems that are in use in refrigeration applications.
Installation, start-up and common controls.
CO2 as a future refrigerant.
Have a look at the lessons below for details!
This is a college level course which spans about 42 hours in the classroom.
9 Separate lessons, lecture style, and running approximately 11 hours total.
Quizzes and tests throughout to ensure your progress. (12-18 hours)

Very linear and well organized, easy to follow along. Anytime I felt unfamiliar with a certain topic, with how the videos are organized, it made it really easy to find the answer.
