Industrial refrigeration system basics, in this video we’ll be looking at how ammonia refrigeration systems work, starting at the basics to understand how industrial refrigeration systems work. We’ll be looking at system schematics and animations to build your refrigeration knowledge. We cover why we use ammonia, where we use industrial refrigeration, single stage systems, two stage systems and cascade systems.

I know when ammonia systems age and fail they are pretty catastrophic like in BC a twin rink arena system failed killing a technician, municipal workers and a couple of firefighters. Our one ice rink arena in town was dangerously worn out and it had the ammonia system run under the rink. Ammonia is probably obsolete by today’s standards as rink systems from ice cube (stylized as ice^3) (the system in use at our newer arena) use R410A and are only charged with 20 lbs of it.
Good video, thanks engineering mindset team
Can LH2 be used in the exact saame way? If not how dan it work? Thx
I'm currently taking my power engineering level 5 and this is super helpful for understanding when you are just learning. The videos they have with the course are so boring/terrible/old. I'm so glad I found these
is any good book about it ?
Beyond awesome, Cheers!!
8:53. How can increasing the pressure of the receiver help liquid flow more easily from the condenser to the receiver?
Would you consider tackling the absorption ammonia refrigeration system? I realize these are small scale but your delivery is so great, it would make my day:)
Why oil lubricant mix nh3 in compressor?
Industrial refrigeration and its concequences
Awesome… I am an Industrial Supervising Electrician. We work on all Electrical and Control for these systems, while also doing Everything else that is Industrial Electrical. Loved this Video !
I was on an ammonia hazmat team. We did have a leak that I discovered in the beef fabrication department while working food safety.
มีแปลไทยไหมครับ
what's the difference between a liquid separator and liquid accumulator?
"It all started when I couldn't get anybody to fix the ac in my 96 Cherokee." 🤔
Sub titles are hindering the illustrations, modify it,or keep margin for it …rest best technical e learning forum, keep it up
I love this video. It's in my nature to nick pick, I think it's my way of forcing me to stay focused.
"Unwanted Heat from Evaporators"… Oh come on, Engineering Mind Set, you are harder to please than my ex-wife 🙂
Great explanation…
I have an alternate method to this that is way more efficient than a cascade. We have hit -112c with a single stage system and can get much lower. Patent Pending!
Don't need the liquid separator either . This system is set up wrong with equipment it doesn't even need ! I have built a few engine rooms in my time. I worked with a guy who trained me and we called him the ammonia God ! lol Really smart man .
There's no need for the ammonia pump in this single stage system , The 75lbs of receiver pressure will push the liquid ammonia into the evaporators , Which are also in a vacuum ! Think about it for a minute , the receiver has 75lbs pressure which is going to a evaporator that is in around 8 inches of vacuum ! Why would you need a pump ??? you wouldn't !
