If it weren't for prompters, how many edits are added to the final cut..wow.👌👌 Thanks Brian and the others at HVAC/R School who make these educating videos possible. Please continue to bring us more videos like important protection for service technician and precautionary steps during service of a suspected burn out., and proper steps to clean the system, what parts should be replaced etc, and get it running again.
I’ve already went through HVAC trade school, graduated with flying colors, got my universal 608, been working in the field for about 3 months now, and I’m still watching these videos. I guess I’m fully dedicated to this magnificent trade. But man do I wish I discovered HVAC when I was younger. Better late than never!
Same here. I'm 40 now but I was always interested in HVAC in my younger years but never got in to it until I was 30. Been in the business for 10 years now and still learning about HVAC. I'm more into inverter system atm. Most of the technology is moving forward to Inverter for more efficiency.
Female homeowner here and thanks to you I know so much more about my heat pump and it's operation. I can now have an intelligent conversation with the HVAC guy when my system is not functioning properly.
This video is simply superb. As far as educational content is concerned, this is one of the best videos I’ve ever seen. Thank you so much for your work!
Thank you very much a very thorough explanation of all the system components. As a homeowner and one who installed their own system, it is great to know what all the functions are on my system..
This video is GOLD! Being a new HVAC tech this 3d model is amazing to actually see the inside working components operate and flow. Thank you for this video!
My AC is great again thanks to you. I did a compressor replacement not from a burnout but rather from age 20 years old and a very high electric bill. I learned about compressor oil is hygroscopic along with the correct compressor replacement voulme. I replaced and moved the clogged dirty rusted dyer line filter to the air handler in the attic. The filer by default was outside at the compressor Goodman. Well that didn't seem correct even though the manufacturer had it outside when ever video said put it at the airhandler. Well now I know why it looked like it came from the bottom of the ocean. I even put in a sight glass with values correctly oriented in the proper direction on both side. Yeah, I burnt two sight glasses but I learned how to do it correctly without the black dot of death inside. You know you guys have done this also :) Now it's roasting hot and one year later it's working great.I even filtered out all the fires from canada using my airhandler. You literally saved me big bucks and no leaks. I know you ac guys are going to hate but with the right skill set you can do it (Rob Schneider aka Duce) thanks to this channel.
Cruised through hvac school, got my epa universal, landed a sweet career as an apprentice and already a month in. I’m loving this field so glad I got into this. Knowledge just never stops, so rewarding to understand what you are saying! 💪🏽👨🏻🔧
Yes this should be sold to schools,graphics, or as you say 3-D model. Format is 21st century. Yeah man! I had old dead units,old dead techs (lol),2-D books at which to wrap my understanding of heat pumps. No one would elaborate, maybe they were not sure,or just insecure. Thankyou Again!! Great content as usual MR. O..
Thanks Brian this video is a great tool for H.O.'s to explain operation in place of lengthy on site representation. I am retired from the HVAC industry as an owner/ service tech. I also live in central Florida. Wouldn't mind checking out your operation some time.
I wish i had videos like this during my bachelor years. It would be much much easier to understand and extremely more interesting . Thank you a lot HVAC School!
Very good presentation. I especially appreciated your comment on refrigerants boiling cold - that was what I was missing. For your state change (liquid to vapor) you may give the example of 212 degree water going to 212 degree absorbing 970 btus/pound of water, not the normal 1 per degree change between lets say 211 and 212 degrees. 2ndly, it helped me to think of the AC/cooling portion is sucking the warm/hot air over the coils so that the heat can be removed and the resulting cool air being expelled into the room. Many folks look at this as blowing air over the coils and can get confused. As others have stated, this is a wonderful preseentation - thanks again.
Like the picture of frosted outside unit heat pump. Typical central FL situation where homeowner turned on lawn sprinklers in attempt to protect their plants from freeze damage, putting a lot of local humidity in air near the outside unit.
Very nice air conditioner heat pump parts overview. I dug the 3D pictorial motion graphics and this information gave me a much better understanding of this technology so that I can better serve our HVACR customers.
3D hi-speed ADHD gold! This is your best yet! Colorful, concise and clicks along at an exciting pace. Really keeps my attention. Does having 10 kids make your teaching style evolve like this?
06:35 These are called _aspirating_ accumulators. They are sometimes pre-charged in the field with a small amount of oil to minimize the aspiration of liquid refrigerant. better solution is a separate oil separator ahead of the accumulator, and a low oil cutout in the compressor. I have seen more than one Coplemetic compressor throw a connection rod due to poor oil return. The nice thing about Colemetics is they can be rebuilt, unlike standard herms.
Amazing Video thanks a lot for all the work to get this étayé if the art explanation for the hvacr leasing community and and curious fellow Bravo make us more of the 3 d ones happy new year 2023
The heatpumps I've been working on here in germany don't have a transformer and all that wiring, just the 400V for the compresser and 230V for the controls. I think all that is integrated into the main circuit board most modern machines here, 230V going directly into the circuitboard, and the board is spitting out lower voltages for the sensors and stuff.
I have to say, your videos are so incredibly educating even for those not in, or training to be in the trade. Your channel, Craig with AC Service Tech, and Curtis from HVAC Guy are the best. Are your animations from Interplay HVAC Simulations?
Hi I was wondering how much length is required for heat pump. Or sould I say what's the minimum length is required between inner unit and outer unit for heat pump to cool down well insulated place ?
Ive worked on a few heat pumps that didnt have any accumulator on em.. the compressor wasent ever the issue on those systems though.. except if the accumulator was installed somewhere away from the compressor, which would make it usess:.. right?
Im have been trying to find out if that was to install a plate heat exchange on the low side to cool the high side if it would raise the efficiency of the unit
Do you have any section drawings or diagrams that you can share for a heat pump system in a residential high-rise? i.e. whole package install including drip pan to external drip pipe outlet on the facade of a building?
Question I have a heat pump that's in the heat mode and runs the pressures up to 500+ psi then locks out but in the cooling mode it runs fine. It has a TXV on the HP. I believe the TVX is bad. Feedback when you can.
Sounds like the outdoor TXV is stuck open, or the bulb lost it's charge. You can try putting the sensing bulb in ice water to see if TXV closes & then put it the bulb in hot water to see if it opens. When your doing that keep an eye on your suction pressure to see if it's changing. 👍
@13:01 it's inappropriate to say the vanes of the squirrel cage "scoop" the air given that spinning the cage in either direction (or flipping the cage around) will still cause it to blow air in the same direction. The air is pushed by centrifugal force and changing the blade profile is only an optimization -- or perhaps a tradeoff between pressure and volume. Teaching that small fact will some day save a student from thinking they can reverse the flow.
