Please CO2 safety information

Thank you for your valuable informations sir, Can you make detailed video for high pressure valve and bypass valve controlling with the flash tank.. How to control rate of vapour generation and liquid generation.. and control(opening and closing) logic of flash tank. It would be helpful for us... Looking forward for your valuable response

You're so much of a refrigeration guy you don't know it's called an air curtain. And the fans can't run backwards you can only put the blades on the wrong way

I have a question, Can the primary nozzle of the ejector receive a saturated mixer phase?

I HAVE A ONE QUESTIONS ABOUT COMPRESSOR CAN YOU GIVE ME Reply

Great information

hi trevor. i was a refrigeration engineer with NH3 experience and a working knowledge in CO2. However finding some employer to practice my CO2 knowledge is limited. is there any company that you could help me with so i can get a position? thank you.

Whats the song

doesnt get any better than this. thanks

I just replaced an AC and heater in a 22-year-old home. After 2 days the compressor stopped working - just ambient air from the vents. The thermostat actually alerted me to this with an error message. The company came out quickly to check - the compressor was very hot - they cooled with water (I'll assume to reset a thermal switch) - it ran for about 5 minutes then shut off - the fan still working but no cool air. The unit will be replaced tomorrow but I wonder if a 4-ton AC unit (Had a 5 ton for 22 years) will need to work harder than a 5 ton, thus running longer before the home cools down to the thermostat set point - and if it runs longer, will it heat up more and possibly this happen again? Vent calculations were done, a 4-ton was called for, so I can't really question this, but I think strange a brand-new unit would fail at the compressor. Are there things I can check weekly after the new unit is installed to be sure it's not going to fail when it's 95+ outside. I will monitor the temp at the exit of the compressor (just outside the AC unit) and it should be very cold. I will take reading with an IR thermometer and note these. One other thought - if the duty cycle of the compressor was 70/30 (on/off) I can see it might not have time to cool down before the compressor starts again - thus heating up an already hot compressor. Any way to estimate how long it should take a 3400sq/ft home to cool from 78 to 73? is there a rule of thumb in this area? Yes, window efficiency and air leaks in the home will matter, but just in general.. should it cool 2 degrees per hour? more / less? and if the home heats up from 3pm-8pm and the AC can't keep up, so it's on all the time, does this mean I need a larger AC unit (more tonnage?) Thanks for any input.

Hi trevs benni here tell me do ypu only desl on only commercial supermarkets refrigeration or do you also deal on domestic . Im.asking rhis question case most of your vides i follow or watch its only commercial. I want to learn and expand my knowledge thanx

How is leaking CO2 that is returning to the environment that it is taken from bad for the environment?

Is it possible for a Bitzer motor that runs on Co2 gas to have its operation system changed? It runs on Freon gas

Great video! Where can i buy one of those emerson demonstration?

very informative. Keep it up, brother.

👍

Hi Mentor, could the refrigeration system be located in a different floor than the ice field? Im looking at a case in which the ice field is 8 meter elevated from the ground and the refrigeration system would be located in the ground floor where we have 200m2 available and easy access from vehicles. I would very much appreciate your feedback. Thanks!

Hello. Do I need to get a license because the entire program is not installed? E3 controller.

iam interested in optimizing the co2 system for maximizing the subcooling and superheat. Is therer anyway i can learn practically i mean like a traiiining center.

Click where exactly for the compressor guide?

Sir about the valve plate I forget to put a number marking thats my concern thanks

I love u teachings can i have ur number sir or email

Why my hammer mill destroying oil pump?

Best educational video, thank you

I have all that after 30 yrs. Just wish i could give my knowlege on a thumb drive and load all my experiences to someone who really wants it.

Haha... I didn't know the oil can have some "particular" in it once it runs through the system. How about impurities or... particles?! I guess that was the right word. I know, camera gives me track too.

It helps to prevent discharge pressure to bypass into suction which will cause the system to short cycle even if the system set point has been reached at the evaporator. Also, as Trevor stated in summary, the discharge vapor equalizing into the suction will cause unnecessary high load and torque during startup every time the motor energizes because of the higher pressure on the low side. This is compounded by the potential of short cycling. Faster wear on motor windings and shorter compressor life.

Let's say you don't have ports on the oil filter. Can you check the line temp on both sides of the oil filter, looking for a temperature difference?

How many tons is that compressor?

My dream is to meet you, work with you and learn from you are amazing man i wish i would be like you one day God bless you❤

I thought all scrolls compressor had the check valve whether for refrigeration or comfort cooling

Hey Trevor took your compressor master class a year or so ago. Love your channel. Thanks for all the helpful information. Will be reaching out via email tomorrow regarding some questions on 448/449a low temp systems. Seem to be having a lot of issues with scrolls failing using 448 for freezer applications. Not sure if the liquid injection is intermittently failing or if 448 just has a hard time at low temp due to the low pressures to achieve the -10 temps

thanks for the video, pal! you from the east coast in Canada? I detect an accent lol Ontario here

Hey Trevor. Long time fan. Do they also have the floating seal before it?

latent heat is the amount of BTUs it takes to cause a phase change in a refrigerant or the air, correct?

Are you in your right mind to suggest Co2 as refrigerant in refrigeration systems. Dont you know that at 31 C CO2 between liquid and vapor phase and compressors of refrigeration systems burnout while compressing vapor

Im astonished how many compressors I see as a rebuilder that come in seized with no oil in , we will send a new compressor out and that will be back to rebuilt the following week, engineers dont really care or know how to test these systems.

Thanks for sharing this i just learned something new, this tells me to replace my accumulator after the system went water since the shell and tube condenser had leakage and the was a lot of water in the compressor and evaporator(Trio skinning drum ). Although i flushed out the system with nitrogen.

I was surprised to see that a presentation covering carbon dioxide didn't use the correct chemical symbol of CO₂. If you made this basic error, it sort of sets the scene portraying an overall lack of real knowledge and background to this somewhat complex issue.

When the world will understand that this is not a reasonable direction of refrigeration development? Correct direction is R717, R1270, R1150, R290, R600a, R600, R170, R50. Only subcritical and low energy comsumtion systems!

When it is very hot outside, my fan stops working. And then I pour ice cold water on top of it. It starts running immediately but again after about an hour it stops. Can you plz tell me what could be the problem. Thanks.

Congrats. Well deserved. Low key saving the planet one tech at time 😂

In the past have had a leaking packing gland, had some rota lock seals and the smallest one was just the correct size to fit over the stem and leak stopped.

Uh-oh... this video is not for the uneducated (me). Just an old person looking for a way to fix my chest freezer i use as a frig (it's only a year and a half old; overheating terribly). Thank you.

Reaching out to hill phoenix on their andvancor rack. You got any info on them?

So... it's not a hat?

I love your teachings
