Good information bro

Man, someone needs to mute their phone but just wants to be an ass hole.

Sir, Your videos very knowledgeable

Great

Marvellous...

I think this may have been the best explanation of headmaster I’ve ever seen. I might have more compliments later but I’ve only gotten that far.

Cool video Andy’s Beverage Company I work at lancer for ten years been running Andy’s since 1999 love soda pop industry……

Omg, please stop clearing your throat. I have to watch this for class and all I want to do is mute the audio.

Thank you so much!!!!

Thank you very much for your insightful videos !

Good information

I am getting starrer in supermarket refrigeration.

This video is best viewed muted to avoid having to listen to all of the coughing and throat clearing. Thank me later.

This might be a dumb question, but What kind of pay should I expect from a company makes these products, I got an offer for fountain technician. I'm currently a jetski and jetboat technician I'm just wondering what to ask for pay because they ask me. What do I want to make?

Almost all ductless mini split heat pumps now use EEVs as the metering device. For multi zone systems they use a separate EEV for each head.

Great presentation, thanks for sharing this videos 👍🏼

Great video information 👍 thank you for sharing your knowledge and experience 🫡🇵🇭

How do we identify rotation of compressors? Do you base that solely on wires arranged at contactor? Or do we verify from compressor wiring box mounted on compressor? Is there any other way?

A good question i will get back to you as soon as possible.

Absolutely superb presentation, extremely interesting and informative thank you.

At the end, it said high subcooling is a result of incomplete condensing and caused by flash gas. Thats wrong, that would be the definition of low subcooling. i.e. not enough refrigerant in the condenser. Also in comfort cooling, subcooling is used to charge a system when a txv is the metering device. If the system has a fixed orifice or cap tube metering device, total superheat is used for setting the charge. Regardless, even a txv system we need to confirm the txv is working properly by measuring the evap superheat. Normally in the range of 8 to 15 for most systems Ive ever worked on. Not sure where youre getting 30 and a max of 40 from, that would be a seriously starved evap and wouldnt be cooling the space at all at those numbers and would cause a chain of problems on that system,

Do you include twins scrolls?

Refrigeration is pretty cool,its a sensitive science where alot can go wrong.

I really dont care what size rack,I like them all.

What's the slave coil?

So ice sits on the cold plate?

Great explanation!

Excellent communication and explanation! Systems approach always wins. Keep up the good work

Thanks. Why would a lower suction pressure cause higher heat of compression?

Thanks for the knowledge that you share ❤️

Wow very informative and easy to understand.t

This was a great class. In HVAC commercial but not refrigeration. Really enjoy these classes. Thanks for giving back!!

I designed this rack almost twenty years ago when I worked at Hussmann, does anyone know where it is now?

Great people and great company ,they try to help how ever they can . Great job keep it up

Min 30:00 King valves/3-way valves: thank you for an explicit refresher on this. "Get something wrong here and you could vent a whole system in your face.*

Min 19:20 What is "snap-torching”?

Would be helpful if the flow direction were shown on the filter-drier illustrations.

Min 30:00 Could use a diagram to show where all the isolations are taking place. Experienced guys will know what you're talking about, but if you can understand it at that level, you don't need to listen to the course.

Min 20:00 Need a diagram to show what's going on with "stacking fluid" in a condenser.

Thank you sir

What is a PID?

For the beginners watching this, don't expect yourself to be able to "pass the test" for the this video. It is for people who already know the reefer business. Nevertheless, after the 2nd or 3rd play, try challenging yourself by just listening to the audio and see if you can follow flow and jump-arounds, sentence by sentence, and clause by clause.

These guys are "doers" first and "teachers" second... That's ok, but as a learning experience, it could be better. I'll have to watch this several times to "get it" - can't keep up with the complicated flow-diagrams, then the overly folksy "your xyz valve" and "your xyz meter". But here on KZfaq we can stop/rewind/repeat. "It's a start."

This is great to have because it's online - you can STOP, rewind, take the time to study the diagrams, then go back and replay the dialog to match the dialog with the diagram.

Knowledge is highly appreciated. Thanks

Great class. Do you have any videos on saturation points for freezer or walk in coolers?

Great class

Thank you for this great information I have a question could some reach in freezer has a CPR valve like 2 glass door or 3 f door or 5 glass door

If we reduce the load of the compressor or VFD to decrease the speed of the motor, does it effect to the discharge pressure ( discharge pressure is too low), reduce the condenser capacity?
