Of course you can edit, delete, or add to the default course that is provided, but you start out with a complete course.Benefits of SimulationX for Aerospace Applications MyHVACLab provides a complete HVAC/R course that ties in with the book. If purchased packaged with the book, the cost can be as little as $7 more than the book alone. There is no cost to the school to use MyHVACLab students must purchase an access code. If you are using Fundamentals of HVAC/R, consider using the on line MyHVACLab online course management and content that is designed to work with the book. Some time spent playing with this can really explain how changes in system variables affect the whole system.

The Carlyle site has a program that you can download called Compressor Selection software It is a complete refrigeration system simulation! You select the compressor, the refrigerant, choose the condensing and evaporating temperatures, and the program will show the capacity, energy use, temperatures, and pressures throughout the system. Several compressor manufacturers have great technical specs available online including
Their HVAC/R specific materials can be found at Fluke But the search is worthwhile, they have so many HVAC/R products and do a great job explaining their use that just looking at what is available and what it does is helpful for the students. You can “use” a meter online by going to the page with information on a meter and choosing “Virtual Demo.” The Fluke site has so much that it is easy to get lost navigating the site. Some of the more interesting features they have on the web site are virtual meter demonstrations. And again, I don’t mind the materials talking about Fluke products since they are providing them for free.

All these materials are obviously designed to show how to use Fluke products, but most of the information is applicable to testing in general. Fluke will send you training videos on DVDs for free. I especially like the electrical safety materials. The address isįluke has a boatload of articles, demos, videos, and simulations. They do use their products in the videos and the videos do promote their products a little. They are available in a small format that will stream on the web, or in a larger file size that can be downloaded for larger screens and better resolution. They are very well done and cover the basics of these important subjects.
They have videos on Refrigerant Recovery, Evacuation, and Tubing Tools & Techniques. Click on US Motors to go there.Īnother favorite is the Yellow Jacket site. It will take the students a while to work through each course, but they will learn a great deal about motors in the process. These are not 10 minute time wasters with glossy promo photos and little information. After the students complete the training, they can receive a certificate of completion in the mail. The modules are Motor Cross Referencing, Motor Mechanical Terminology, and Motor Efficiency. I believe my favorite site contains three very well done online training courses for electric motors by US Motors, a division of Emerson. If you know of one, please share it with the rest of us by posting it on a comment to this article.
I am sure there are resources that I don’t know about. It takes some time to dig around the internet for them, but much less time than it would take to produce comparable materials yourself. Our students can benefit from these offerings. Companies who take the time and resources to make training materials freely available to the HVAC/R community should be supported, applauded, and encouraged because educational resources freely offered are a gift to the HVAC/R community. Money spent on training saves money on warranty returns. Time spent educating technicians in advance saves time trying to do it over the phone in an emergency. Forward thinking manufacturers have figured out that showing technicians how their products work, how they should be installed, and how they should be services saves them time and money.

There are some well done power point presentations, videos, and articles that manufacturers post for free on their web sites. One way to provide access to online training material is to point students towards information offered by component and equipment manufacturers. But I love for my students to do research on their own time after class it shows real interest in HVAC/R and commitment to our trade. If you are like most of us, you are already working at home to prepare for and manage your classes, especially now that enrollments have swelled. I know that most instructors simply don’t have the time to create online content. Many of our students are accustomed to 24/7 access to electronic information.
