I've never found such a good video. Great lesson! I now understand the process. I haven't been able to comprehend it, but you teach it better than most.

after attending a local hvac school,here in Pittsburgh pa, I've learned more then what I paid for, your knowledge and time spent explaining the basic functions, will help me in my current job.....and future thank you so much.....

Thank you Ron, I am currently enroll for a refrigeration class, for a NYC refrigeration license. Your explanation made it so much simpler. Thanks again.

Thank you. My heat pump compressor failed. I watched tech. put new one in unit. Fasinated asking him questions how it worked. He did his best to explain it. Been watching videos for hours trying to understand the workings . THANK YOU VERY MUCH AND GOD BLESS YOU FOR YOU HAVE HELPED ME GREATLY.

You're welcome! Let me know if I can answer your questions. Did he tell you why the compressor failed?

Hi, The info you have provided has been clear, explicit, interesting and factual. This video has broadened my knowledge of refrigeration.I am a qualified electrical engineer and repair numerous diverse electrical systems including refrigeration. The video is excellent many thanks

Hello Mr. Walker. Thanks a lot for taking your time making this wonderful video. It is very helpful, and can guide a lot of people like me, who want to become an HVAC tech. It will be even more appreciated if you could make some introductory videos on how to become a tech and some useful material through which you could endorse your services too. Keep the good job and caring for others!

Thanks Ron for the all of the time you invested in making this video a hit. About the figure of the AC unit, it could be that the evap. coil fan sucks the room air over the coils and sends the cooler air back into the rooms via ducts, making the fan point in the other direction. This would better point out how the heat (molecules in motion) is removed.

eggsactlyrobin Good point and thanks!

Thankz ROn for this great video.. Please send me a module demo for all the lessons you posted via youtube.. thanx a lot

Thank you for making this video now I understand my class so much better.

thank u very much sir , may,God bless u for this wonderful efforts

wow!!! this is such a good training video, thank you Ron.

Great Training Video. Thank You!!

Great video! Thanks for sharing.

excellent educational video...Thank you Ron

well done...best video I have seen. I liked the way you explained stuff....made it really easy, even for a hard head like myself..lol

Great video! Very informative!

VERY GOOD LESSON. THANKYOU. I WANT TO LEARN MORE.

good job Ron

excellant explanation

Very educational

Really nice video! I just wished you used Kelvin degrees!

Thanks lot sir... It is really useful.

Nice work Brother - really nice work!

Thank you so much :)

Thanks for sharing this outstanding video! Just don't understand why 100% liquid refrigerant became 25% vapor & 75% liquid after passing thru the metering device?! According to the video and gas law, when the refrigerant passed through a metering device, both the pressure and temperature will be reduced. My question is that if the temperature of the refrigerant is reduced, how can liquid refrigerant be turned into vapor state?? Please help?

The reason the refrigerant is able to become a gas so quickly at the metering device is because of the high pressure in the condenser ( which is the high side of the system ) the high pressure gets pushed through the metering device creating a flash gas. Think of it this way, when you turn on your garden hose and suddenly block the outlet of your hose ( or the "orifice" ) with your thumb you begin to drop the pressure of the water leaving the hose and if you notice some water will mist. If your interested in learning more about expansion valves ( metering devices ) then I suggest this text book all the trade school use this book amzn.to/1D0bb0C

Towards the end you said basically what you are doing is taking the heat from inside and dumping it where it isn't needed or something to that effect. Couldn't you put another heat exchanger in and dump that heat into a tank in your basement for domestic hot water and practically double the efficiency? Yes, you would need to add a tank in your basement and plumb to it but it would remove more heat from the super heated refrigerant cumming out of the compressor and it would be that much heat that would not be needed from the water heater. Why don't manufacturers do that? the heat exchanger would be under $200

bosthegr8 Great thinking. Actually several years ago they were very popular here in FL... not so much anymore. I am not quite sure why. Also in states like Montana, some of the supermarkets take all of the heat removed form their coolers and freezer and reclaim it to heat the store in the winter. The use a huge condenser coil and fan to blow air across it. In the summer it is shunted to an outdoor condenser coil.

awesome

Awesome video thank u!!!!!!
