Wow! Back in pre-YT years, a young tech could spend 10-years trying to figure this stuff out (if then). I hope those watching your videos appreciate the years of experience packed into your stuff.

I'm starting a new position as a Supermarket Refrigeration Technician and I find your videos very helpful and informative. Thank you!

Thanks for sharing your knowledge,im trying to get into refrigeration,this is alot better then a book.

I like seeing those massive old school valves like the HG differential valve you showed.

Thank you so much Bro. Its worth following the channel. I am new to supermarket rack refrigeration system.

The A8 valve, classified as an ORIT valve by Sporlan, and the A9 valve, classified as a CROT valve by Sporlan, you explained their function in a refrigeration system very well. Hopefully, the receiver on the system that utilize this type of head pressure control has been sized large enough to handle the extra refrigerant charge needed for the flooding. As you already know, that excess refrigerant has to be held by the receiver in warm weather months. Also, as you already know, the amount of extra refrigerant charge needed in a system utilizing condenser flooding can be lessened by using a system that has a split condenser, consisting of a Summer/Winter circuit and a Summer only circuit; both used through a 3-way valve in the discharge line. Doing it that way allows for a smaller capacity receiver to be used.

Great job Doc

Thanks for the detailed explanation 👍

You’re awesome man. Thank you

Thank you so much for making these videos, I have been a HVACR service tech for quite awhile now but I never touched racks until about 6 months ago when I moved to a new company that has a refrigeration department that handles almost exclusively super markets. I had been working mostly in commercial food service so I have a lot of experience with walk-ins, self contained units, ice machines, and specialty stuff like slushy machines and blast chillers but there is so much different in rack refrigeration with all these different valves and things that smaller systems just don't use at all that it almost feels like being fresh out of trade school again and your videos have helped me quite a bit during this change so again thank you.

We have our receivers in compressor rooms so that they don’t get too hot

I could watch your videos over and over again thank you very much for showing if showing the new guys these tricks

Thanks much! I thought this would be a "3-play", but 2 plays and I've got it. Great format -- a walk through the rack room to get the Questions percolating, then all the questions get answered on pencil-and-paper. This sure straightens out all the Push-and-Pull that goes on with the Receiver/Condenser and dealing with what happens on cold days. That "low ambient temperature" stuff really throws a newbie for a loop (but here's a good place to start.)

I usually see a dif valve of 10 to 20 pound from receiver to discharge instead of a check valve to drop leg

Merry Christmas 🎅 🎄 and happy new year to you and all your beloved ones

Good day, thank you for the video! Would you be able to touch on surge receivers and the settings needed for the inlet and drain solenoids? Thanks

Can you please make a video of how you set the hold back and A9 valve please!

Hell yeah

I'm working on a Rack today had a few cases running warm a leak was repaired . I added some gas but instead of getting 1 ball i got two balls with a half sight glass it would go away and come back never got 1 solid ball what could this be?

my wish am work with you
