Good
Helpful.thanks.
Could you please make a video on vapour injection system in scroll compressors?
01:17 into the video, and the second commercial begins.
Remember when youtube wasn't obnoxiously innundated with excessive commercials ?!?
Pepperidge Farm Remembers !
I Love the fact that a channel like this can even exist :) We live in great times
No we don´t. the earth has corona
Are you being ironic? We face a future of climate chaos and ecosystem collapse, and you think you live in great times? Geothermal energy is energy taken from the Earth's core, it comes from heat generated during the original formation of the planet and the radioactive decay of materials, and is not green in any way. Just because it doesn't cause CO2 emmissions some shallow thinkers imagine it's part of the solution to global heating, it isn't, it's part of the problem, and while fossil fuels are being phased out geothermal is expanding because simple non thinkers imagine it's green. Just repeating low carbon is a mantra to reassure those scared of the consequences of climate change. Dream on.
Indeed we do. Kids nowadays have no idea how good they have it.
But then, it's always been that way. You need to live a little, try to survive off grid for a while. Then you can come back appreciate glorious civilization!
@@davidjessop2279 lighten up nerd it's an opinion lol
we have the adequate knowledge that came from the mistakes of our ancestors, if we acknowledge every knowledge and failures that they have made I am sure we still have a chance to rewrite this world
Been a HVAC engineer for over 30 years was in hospital brushing up watching your video's you never stop learning and also you forget a lot of basics over the years brilliant videos . Are you putting together a book ?
Do you mkake good money doing this?
You bet, Abdul, you bet
Keep on learning
I’m 36 and have been an HVACR tech for 17 years now. Heat pumps have come a long way. I don’t care who says what they are very practical and efficient. Check out the Mitsubishi Hi-2 versions. They give you 100% heat capacity at 5 degrees Fahrenheit and 95% heat capacity at -15 degrees Fahrenheit!!! That’s insane.
ApprenticeThatTextstooMuch and the electrical costs are?
@@sheledmikymo MUCH lower than using a typical space heater
Its the LED equivalent of heating
@@sheledmikymo Very low compared with heating with gas and especially low compared to electric resistance heat. Heat pumps don't create heat. They use electricity to move refrigerant, which carries or "pumps" heat from inside to outside or vice-versa. That takes a lot less energy than creating heat.
Is it possible to power an air to water heater with a solar panel
@@jodygallagher8829 Yes, with a large enough panel. It wouldn't take much.
These are by far the best and most clear videos that I have found. I use them in my Adult HVAC classes and they benefit my students greatly. Thanks for clear, concise, accurate, and sometimes amusing videos!
yea but i think that the part at:
6:22
is misleading for people who just learn about this stuff
from my personal logic/understanding the expansion valve just maintains the two different pressure zones and its not the thing that actually turns liquid into vapor
I'm pretty sure that its the pressure drop doing that, and the pressure drop is caused by the compressor
but this is just my logic and maybe im just nitpicking...
anywa, the video is great
I've been looking for a simple explanation like this. The only way this could be better is if you showed an example of the physical devices for the indoor and outdoor units or parts. And thanks for the great video!
That’s a great video, I really like that you stop to point us in the direction of other videos that explain the various stages in more detail. Really brilliant stuff, thanks.
I’ve been checking out your videos for a while now as a student in the HVAC program at Kennedy-King College here in Chicago IL. HOW WONDERFUL !!! 😊👍🏾
I like how Paul explains information. Bravo!!
I live in the tropics. Never heard of heat pumps. But imagined it to be a 'reverse' AC unit. Very helpful explanation. Thanks
Excellent explanation as always. Thank you 🙏🏽
I smashed the subscribe button so hard after the first vid I saw. THANK YOU
Great explanation! Great work! Thanks @The Engineering Mindset
This is by far the best video explaining and illustrating how heat pump works. Some other ones on here seem to assume you already have a master's degree in HVAC to understand them.
Those animations help so much. About to start our chapter on heat pumps in class today. This helps so so much!
Your channel is amazing for videos and learning!! Love it!!
This is the best explanation on CZcams of how an air conditioner works. Kudos to you.
I always love your videos very clear and crisp.
Great explanation! Great work! Thanks @ engineering mindset
Awesome vid. Great refresher for this ol auto AC tech.
The best explanation I found so far, thank you. Will watch all of videos to understand the principle. I want to start this type of business in Kazakhstan in future, so just researching
Great service you offer the HVAC community 👍
I’ll be honest that is much more complicated than I thought it was gonna be. Great explanation!!
It’s crazy to think the amount of knowledge you need to have just to be a red seal tradesman!!
Kudos
Great video! Nice work. Thank you.
Incredible, great video and animation, thanks.
Love this channel
Thank you so very much!!! Very helpful.
I wish you did a video with graphics. Such as within the pipes. Show each process in detail as it passes each component. Essentially combining all your videos in one. No complaints here. Love your work. I’m just asking as I learn better with pictures and visualizations. One of the reasons I’m attracted to your channel. Thank you
Great refresher!
I have a Carrier PURON heat pump system installed in 2007 and it is still working wonderful here in Pensacola FL with only a few breakdowns from minor parts from time to time!
Absolutely prefect to need.
Really good video. this is what i was looking for
Hello Paul, I just discovered you CZcams channel. I think it is absolutely amazing. I'm on a quest to engineer the most sustainable home. I'm wondering if this is a topic you might make some videos on.
To quote the unforgettable Terry Thomas.....'Oh I say!...what a perfectly splendid, top hole video!"Very clear diagrams, excellent narration, well explained. When I have to have one, I'll back-refer to this vid.!
Thanks for sharing your know-how.
Great video man. thanks the explanation
Thank you. The best explanation I have seen 👍
Thankyou for explaining in such a way that i understand. I have watched other videos but it just left me more confused, now watching this short video I get it, thanks again.
Hi Paul. Great work! All your videos are very helpful. I like to know what your thought about heat recovery system use in chiller. If possible make a video about it as well.
Honestly these videos have made my life much easier
I’ve been fascinated by this process because it’s in a closed loop, I know a high pressure side and low pressure side, but flipping them is brilliant.
Yep, it is fascinating. I just cannot get my head around how on earth it is more efficient than the water tank with a simple heating rod inside. Pushing the coolant (R134a) in your car costs you approx 10% of the total fuel consumption and some considerable power if you have petrol engine 1.1 litre. Even the most typical fridge-freezer - the compressor is using about 500W - to cool 20 deg celsius in maybe 0.5m3 I am not convinced this system is able to produce 70 celsius on even one small radiator and deliver hot water (52Celsius) to the taps. Have the thermodynamic laws changed recently?
Really, a very explanation for this heat pumps topic......thanks for video
Here in Sweden the Nibe F1255 and Mitsubishi Ecodan are getting more and more populair with outside temp -30C they still are efficient!! We install them every day.
Great vid by the way!👍🏻
Great video!
Great 'happy hour' text at the top. A bit confused but it seems to do with different modes of the heat/compression relationship.
Thank You!
Best explainer 👍✌️🎉🎉🎉🎉
I love everything about your channel. Even the ads. Kudos bro!
Glad you like them!
Many thanks for the video
Thanks in a million. Great content. Awesome imagination. Grade: A++💥
Great job man
Well explained, Thank you
I LIKED THE ANIMATIONS!!!!!!!

Daniel whre now plas ianeed contacting whrea nos kamrmer only
Thankyou vrey good welcoms shreing thankyou best
Wire conneactin pleas explaning
Very Nice sir
3:20 - now I get it :) Thank you !
still difficult to me can you explain ?
Thanks my heart
Hey Paul!
Thank you so much for this very eye catching and constructive set of studies. I am really enjoying them.
I think there is a mistake in the link of "Advanced Heat Pumps", Since it is the same as " How Heat Pumps Work". Could you please correct it, so that the interested people could watch a video over advanced types of heat pumps?
Thanks again.:)
I worked in aerospace and the facility I worked at had many large buildings and lots of workers ....they did not use conventional HVAC they had a central plant that made steam and also water to all the buildings ....chilled water and air movement kept those building CHILL all summer long and the steam lines kept it all toasty in the cold months and provided hot water ...I was always amazed how well it all worked
Great video. Please clarify which is the liquid line and which is the vapor line. Thanks.
very informative vido
Thanks
Best explaination of the air to air system I have ever seen. I have 40 years in the HVAC system and I'm so tired of the "advertising" of the heat pump takes "heat" out of the ambient air outside and transfers it to heat in the house. When it's 10F degrees outside there is no heat there but when I try to explain the heat comes from the compression of the refridgerant out of the compressor I'm told I'm always wrong and even by some of the current crop of HVAC mechanics. I definitely subscribed and liked and will refer doubting Thomas's to your video!
When is 10°f, there's 10°out there. The phase change takes place anywhere north of -15°f, so it's definitely taking heat from the outside. You can test this by putting thermometers in front of and behind your outdoor unit.
Respectfully Chris you're wrong. And what am I gonna do with 10 degrees in a house I'm trying to get to let's say 70? Take your time and figure out what is going on. You'll figure it out and don't just buy the hype of the heat pump. There is a reason modern thermostats let you select an OAT to not activate the heat pump and use Aux heat instead. Just figure out what you have and what you're trying to do. I promise you the light will go on and you'll respond I'm right. I've been in the business way too long my friend.
@@lisajohnson8566Ask yourself how AC works, how can you make 90 air into 45 degree air that cools your house to 65 degrees on a hot summer day? It’s an energy transfer, and each system fluid has different levels of efficiency. This is why a harmful chemical like Freon is used. It can swing over 200 degrees between phases and pressures, whereas water cannot get cold without freezing, so your band is smaller. Efficiency will kill an H2O A/C.
@@lisajohnson8566Additionally, Freon can go as cold as -25 to -55 degrees, which is colder than a cold day, so the needed heat transfer can still exist. The reason AC is much more efficient than heat pumps is the difference in temperatures. The hot Freon is much hotter than outside whereas the cold Freon is only a little colder than the outside cold. Think in terms of relativity and energy transfer more than temperature transfer, which if that was the case, a/c’s would not work and nor would heat pumps.
Thanks lot for the video.
Can you please tell what are the system parameters in case of a Air to Water Heat Pump?
I mean Evaporating Temperature, Condensation temperature for ambient conditions of 12 deg.C. What refrigerant to chose R134a or R410A? We need a hot water supply of 55 deg.C.
I used the exact solenoid with a high flow rate as the fluid pushes down on the oversized valve land for sealing at static pressure. But mine is on an oil accumulator to pre-lube a gas V-8 engine. It is energized with the key on so during starting, it quickly floods the main oil gallery (High-Flow, 1/2" NPT, Viton Rubber Seal; New surplus at 1/10th the cost of Name Brand oil accumulator companies;
with pressurized oil to the bearings. This would greatly extend the life of all "Stop-Start" engines in those vehicles. After being an ASE Master Tech since 78, I will argue a room of engineers under the table! 5,000hrs is the 150,000 mile equivalent that GM designs parts, materials and still make them to keep from paying CAFE a fine. It's a law passed by the Clinton administration.
Great job on the video.
Plz pual make videos on plumbing also.
This is berry effcient
Just curious when using a reversing valve can the expansion valves just be the basic thermal type or do they need to be an electronic expansion valve thanks
Even idiots like me (a historian, with zero knowledge of physics or engineering) can be very much enlightened and informed by this video. I always wondered how my f---g hot air pump worked. Thought it was by black magic. And yet, depend on it so thoroughly (live in Sweden). THANK YOU.
Good
Sir. Please explain with animation about fire pump room
Thank you for video. Why reversing valve is not possible in air to water heat pump?
Great lesson! Could you please explain how HP dryers accomplish dehumidification parallel to cooling? In food processing, HPD are used for low temperature low humidity drying of thermally sensitive foods.
Great work your,videos are awesome, I need to make a project presentation at college can you please tell me how these type of animation explanations is made??
I apologize if this is mentioned somewhere in the video and I just missed it but I feel like its important to explain that the boiling point of the refrigerant mentioned was at atmospheric pressure. As pressure changes boiling point does too. 410a in an evaporator coil is usually at a boiling point between 36°f and 50°f this is why we get air in the 40-60 range leaving the coil.
Good tip. It makes more sense when you apply that information.
I'm confused but this is amazing
Watch videos like this at 0.75 speed. I'm in an engineering field but the speed and pace of these videos can still get to ya. Albeit they are great nonetheless.
Also, it makes the narrator sound drunk, which I think is hilarious in the context of a video like this.
Edit; watched the video on filter dryers so I now get the gist of it, Brill!
Great video, only one thing i dont get, how come the transfer fluid passes through the drier in its liquid state? Sureley this defeats the object of a drier?
SUPER
Awesome Video. I’m a new HVAC Tech and I just bought a house with a Trane Heat Pump Air to Air
How has it worked for you? Do you find it efficient? How cold does it get where you live ? I'm in Western Kanada, it's forced air furnaces everywhere up here. Very inefficient.
Could you add a ground air loop to regulate the temperatures for the outdoor exchanger?
