Does anyone have a good resource for studying for the ASE A7 test? For some reason it is just impossible for me to get the theory into my head, I think I understand how the system works, but the questions about the pressures always confuse me. Anyone have a simple explanation or a link to a good video or anything? I have watched the AVI A7 course and read through the Delmar A7 study guide.
I used the delmar guide and thought it was pretty good. The test is a combination of electrical and hvac questions. I have a hard time with the pressures too and in real life rely on more of a touch and feel test, knowing what to expect there. I think I'd spend some time studying the refrigerant loop, where things should be hot, warm, cold and the transformation of states, gas and liquid.
I believe Matt from schrodinger's box on youtube has some good videos on the concepts that might help.
I've had instructors talk to me about the refrigerant cycle and latent heat over and over for years. I still don't feel like I truly 'get it'. :silly:
Whatever I thought I knew got blown away after watching the CTI Virtual Classroom video on HVAC enthalpy:
Honestly, if you've watched the AVI video and read the Delmar book, I bet you're ready to test. I've noticed many times that the Delmar practice questions are usually much harder than the actual test questions. It can make you question your preparedness.
Plus, like Tutti57 said, there's a decent number of electrical questions. If you understand SD material, you've got those covered.
