I like knowing where a ton of air conditioning came from. Also the heat pump line about the artist formally know as.... great job. Good knowledge with good humor is the best way to learn.
6:10 - I was able to make that connection during the first week of class, Bert! But, what took a bit more thought for me was, “What is saturation? ‘Saturated’ with what?!” The refrigerant is saturated with heat, man! Any more heat and it’s superheated above saturation. Any less heat and it’s subcooled below saturation! That was a beautiful day when I finally got that!
This was a great video! I just wanted to mention that the video cuts ahead at 49:07 and we miss Constant Cut-in Controls, Defrost Controls, and Electronic Controls. I'm not criticizing, I just want to soak up as much information as I can. I'm currently starting a job with a company that does Rack Refrigeration and these videos have been incredibly hopeful to me. Thanks again for sharing the knowledge!
I realize practical hands on is important but I can't convince anyone to give me an chanxe to break into rack work. I've got a lot of commercial HVAC experience and I've worked on plenty of walk ins, reach in's and ice machines but ravk posituons require experiwnce. Are there online courses or training that would prove I've got the required skills. It's pretty frustrating to be honest. I've worked on tand systems. I understand all of the pipe schemes. I understand thevfunction of the controls I may find.I can read a P&ID. I understand how to read PT charts and understand a refrigerants properties based on them. Everything I've watched online is not a mystery. Any help woyud be appreciated
Who is shipping cases or other type units Qbody expansion valves? I don’t think manufacturers are shipping cases with cartridge expansion valves. It’s not cost effective.

Really appreciate you guys. Been advancing my career thanks to you 👩🎓

Thanks so much even after 18 years still stuff to learn

Great input from everyone. Great conversation. Thanks Bryan.
I love your content

17:11 - _Finally!_ Someone uses the word correctly! Go, Bryan! 19:14 - Here’s another: you can _literally_ light a match with superheated water!
Depending on how much refrigerant and what type, it is a mechanical code for there to be exhaust fans and refrigerant detectors
Awesome info guys
I have respectfully disagree with you on temprite vs westermeyer. I find that temprite work great and are easier to service.
You really need to have crankcase heaters on rack systems. Cycle the compressors with the breakers.
Also Fredrick Jones an African American created first box truck refrigeration system and AC. A lil history for you
Correction, American. You're welcome.
The most important temperature you can look at is discharge line temperature. If it’s over 220f then you need to start finding a solution.
3:25 - You could actually say here that the molecules ate “bouncing off the walls,” right?

I think sporlan does with their 3 part system. You build them yourself on the job with whichever part that fits the need.
I love you sir 😘🇮🇳

Why you bully Bert?
