Brilliant video

Great video, though seems to be coming out of one side of my headphones...

My left ear learned a lot

4:35 if an exempt refrigerant is used, then why is it still required to retire the leaking system? It does not pose any threat to the environment.

Very good explanation

The volume level is fine. What are these people talking about 😂

Cut and dry and to the point. Excellent video!

Thank you so much for your video! It helped me a great deal. I will try to share this knowledge with other people too. Thank you!!

Time 0:50 electronics is the study of the behavior of electrons

I’m 17 and wanting to watch and learn all your videos for basic electrical to prepare myself for the future

Thaks sir for sharing your knowledge it help a lot

oak-ay 😐

Your lessons are an absolute masterpiece of hvac knowledge. Thank you for your work!

Thank you for all these videos. I greatly appreciate it. School I went to just threw a book at me and told me good luck

Effective length round is 20:50 but Rectangle is 20:75. Does this mean Rectangular ductwork is better? Or is the higher the number mean its worse?

4:55 I was waiting for something graphic

FR=asp x 100 / tel

Any idea if I would need any of these devices for a small hvac in an automobile that toggles between a 12V and pulley driven compressor? I’m hoping each compressor just keeps its oil… I’d have a solenoid on the charge side and a check valve on the discharge side.

Very useful information. Thank you.

There a little bit of a distinct that I wanted to point out. Between the 39-40 minute mark, when talking about reclaimed refrigerant needs to meet AHRI Standard 700 before being resold. Recovery and Reclaiming "equipment" must be tested and meet AHRI Standard 740.

Very well explained sir. Thanks a lot 🙏

nkn

Just found your channel, been watching the hvacr videos. Thanks

good info

went from 10 degree td to 21 after installing the correct piston

i had no superheat on my ac pumped it down took the line off at the coil and nobody ever installed a piston this ran like this for 9 years

V. V good 👍🙏

Thank you sir I 'm looking for balancing air flow method if you have pdf file please share for me .

410A replaces 22?

Hvac people are so incompetent

I had to stop listening, because only my left ear audio was working

He suppose to have million views l don't understand why

Welcome back, love your refrigeration class.

Very useful thanks for sharing

Thx. Need this info to design 3d printed ducts

You Gave Me Very Useful Lectures. Thank You For Engineering Knowledge.

thanks so much for your lectures on epa 608 core, t1, t2 and t3. Yesterday, I took exam at Seattle Central Maritime. Passed, 92%- core, 72% - t1, 86%-t2, 89%-t3.

please make a lesson like this for IFGC

Excellent video. Really helped pull of the complicated topics of duct design together! Thank you

Where is the complete course. Do you offer an online learning. Thanks

Don't talk about stuff you know absolutely nothing about. Delete this video.....

Awesome info! Also If the ground water temp is lower than the room temp, then insulate the supply water pipe all the way to the ice maker may increase ice production speed. Add a sold for purpose clamp on magnet onto the supply water pipe to reduce water deposits drop out and hardening on components.

These are all so helpful, great work!

Another excellent video

If if air at initial temp at 36 deg C and RH at 42 % , i want to cool the air at 11 deg C by adding directly chilled water into air through evaporatorive cooler. What will be the following 1. Makeup chiller water flow quantity? 2. Makeup chiller water temp? 3. Chillier Load TR of makup chiller water?

At the beginning you said the ADP is the same as the coils surface temp. But then the second slide its the temp coming off the coil?

Regarding the ventilation rates 406. Is this excerpted from ASHRAE? Is it automatically updated?

Ahhhhhh!!!

Great lesson. Thank you!
