Thanks you helped me get an A on my Assingment!
I couldn’t work out how this system works, until I saw the illustration with the compressor.
Very efficient compressor, and environmentally friendly. Good for our future sustainability.
I once came across a Thermosyphon system with no pumps. Seemed to work well.
John Clarke more for hot water than circulating heating round buildings?
Great video Christopher
Best explanation I have ever seen. Simple short and to the point, but surprisingly detailed and accurate. Great job.
i guess it is quite randomly asking but does anyone know of a good site to stream newly released tv shows online ?
@Callum Santino i would suggest Flixzone. Just search on google for it :)

this is good explanation about heating pumps
Interesting and informative video. Can you tell me what program was used to created the moving graphics?
I am checking with my manufacturer to see if there is a deal near you. I will keep you posted.
I work in the geothermal energy field, but on large-scale electricity generation operations. I have to say this is an excellent video, but the title is a little misleading. It's important to make the distinction between direct use/heat pump geothermal systems (which is the process that this video details) and geothermal power generation, to avoid confusion. In my community we refer to power generation as "geothermal energy," and to heat pump systems as "direct use" geothermal.
It's actually neither, heat pumps don't use ground loops and geothermal don't send refrigerant into a ground loop, it uses antifreeze or water, So this video is totally wrong. In a sense it describes the heat pump but without ground loops.
very well done
why u comment on ur own video
Solar Assisted A/C is great. No compressor needed, just a vacuum, solar collector, evap. pv panel. Let the thermal sun do the work of compressing gas in a solar collector and evaporate and cool
So, this IS a ground source heat pump. It just does away with the secondary loop that is normally filled with water or coolant. I question the 25% gains over the water loop variant. In a well designed water loop version, the only difference would be the power draw of the water circ pump, which is a tiny draw compared to the rest of the system. On the other side of it, the cost of that much copper tubing and the massive volume of coolant would be a significant increase in initial cost. If the copper in the ground ever corroded or was damaged, the repair costs would be massive as well. HDPE, on the other hand is extremely durable and will never corrode. If it did get damaged, it's cheap to replace and so is the coolant or water in the lines.
I've seen a lot of ground source systems put in over the years, and I've NEVER heard of burying copper. I'm thinking that if it were a good idea, and the gains were real, we'd be seeing more of it.
Yeah very interesting use of copper. Funny enough when I started looking into geothermal I assumed everyone used copper due to its heat dissipation properties. until I saw HDPE being used everywhere due to its gradual but larger surface area.
My thought also the copper would corrode plus then it would need to be replaced... The copper tubing that is relatively easy to obtain (commercially viable) is also very thin so corroding to a failure state would not take so long ?
thanks real helpful (not sarcastic)
Pretty COOL!
No pun intended.
Lol.
excellent thank you...........160DEG from 30DEG.........53deg 5ft down.
What does your electic bill look like on season vs off season?
Visit any Nordic country and find this to be everyday product
Frost line is only two feet I believe. I didn't understand this diagram example because different temperatures where used. If 20 degree liquid is going into the 52 degree ground shouldn't it come up at least 50 degrees and not 30 degrees. That is only a 10 degree saving and is it worth the cost??? Also wondering how long does copper pipe last before needing to be replaced in that warm moist rocky soil?
I feel like this is a less robust design. Having high pressure refrigerant lines snake all the way out into your yard and down 100 foot bore holes. The better design is to use water loops to move the heat into ground then have a heat exchanger for a shorter normal refrigerant loop. I realize this requires an extra heat exchanger and a pump, but that pump really doesn't have to be very big or powerful. But its a more robust design.
How do you address corrosion and leaks in the underground copper lines? What is the ground loop warranty for leaks?
good point
Good question. The lifespan of copper piping is 50 years. Should there be a leak pipes can be replaced but with the average lifespan of half a century and the elimination of heating and cooling bill from AC, heating oil, or electricity there is still a cost savings. AC also breaks down as does a furnace but overall this system is much more environmentally friendly and cheaper I’d say
160 degrees Celsius. I think that this heat needs other additions to benefit from it in the winter, but in the summer, unlike the circuit, something dangerous will happen and requires safety measures because the heat will increase when it is pumped into the ground.
So I’m wondering how the compressor gets it’s power? Through electricity ?
Indeed. The trick is that for every kW of electricity you put in to it, you get a total of 5 kW of heat, so you get 80% of your energy "for free" from the ground.
is it possible for refrigerant to contaminate ground water...if pipes leaks?. leaks happen .
ok.. I've been trying to wrap my head around understanding how this works. I'm lost at the point where the return line from the heat exchanger is at 85 deg.. then goes through the reducer and drops to 20.. why drop the temp to 20? why isn't that 85 degrees recycled back through the compressor? wouldn't it take less compression/energy to bring that back up to 160?
very educated after this
this video so interesting. can you explain same thing in cooling the room or use of Geo thermal energy for cold storage.
please reply as soon posible
Yes, geothermal can work both ways.
Is Geo-cooling more economical than geo-thermal heating in zone 5 where summers are hot and humid & winters are bitterly cold?
Common in Sweden. I installed my system 15 years ago. My borehole is 145 meters. Today the boreholes are 180 meters.
are thos degres fahrenheit?
Also, do the pipes get clogged or less efficient with time?
Hello I hope you can help. Where can I obtain the formula for
heating a space as large as 57,600 square feet of open space (no
walls) at a temp of around 75 to 80 degrees and 4 fish tanks that
hold 10,500 gal of fresh water each. And one smaller tank that holds
500 gal of fresh water. The water has to stay between Temperature:
80-100°F, “but”85°F is optimal in the winter. I live in the
North East of Pa.
The reason why the refrigerant needs to drop in temperature is due to the fact that it is liquid state after passing through the heat exchanger. So, by dropping the pressure and sending the low pressure liquid down to the earth, the liquid begins to boil in the ground and changes state back to a gas. During this process is when it absorbs the heat energy stored in the earth. Once this process is complete, the gas refrigerant can be compressed.
In short, I cant send a liquid to a compressor.
Is there casing in the well
There is an easier, more useful and better way than digging all of this just for the sake of extending pipes, and it can be used anywhere on the earth under special conditions according to each region and at a lower cost. But the idea needs support from anyone I might partner with in this innovation
There is a major confusion between tapping into the ground below everything.
And heat created by the high heat of the core reaching the surface of near it
What does the compressor run on? Which power ?
what gas medium is used in this case?
This is the more expensive way the water based system is cheeper to run.
I like how they talk about the underground temperature as this constant. Well it is kinda constant as long as you dont tap into it, but once you do it will deplete it. How much and how quick depends on the specific conditions, but basically the temp down there is the annual mean temp of the region. So if you cool it and dont heat then the average will come down. So to keep the efficiency as good as it is in the first year you have to pump heat in it close to the amount taken out. This makes it more like a seasonal storage and less like deep bore geothermal. So if you want a system like this calculate some kind of solar collector in the bill to pump the heat in in the summer. (unless you live somwhere that is too damn hot and have short mild winters and use the same loop for ac)
Could you please explain how the number of Wells required is determined?

Hi Cristopher, could you please let me know which software did you use to create this video, and which are the similar softwares? Thank you so much.
en df
!??.,
so in essence all the geothermal loop does is raise the refrigerant by 10deg before its
compressed again.
I guess it's only to improve efficiency??.. not sure. Also, why is the thermal expansion valve needed when you can have 85 degree coolant looped back into the compressor.
Do you still need AC power on the compressor?
I got a similar unit like this, in fact we were the first on the block, who had this system. We were one of those test houses 17 years ago.
SO HOW IS IT WORKING FOR YOU??
Nice to know this.
Please share your experiences about this project.

So can this work in any part of the world or is it limited
how much a system like this will cost? which states do you work at?
Does the refrigerant ever get old or something? Do you end up having to replace it at some point? sounds too good to be true if it is just infinitely recycling through the heat pump.
+Julian Franco I'm a power engineer by trade, but you can image how this works by thinking of the Air Conditioning System in a car. Everyone so often, you need to add refrigerant to the system. If you've even bought a car that was 10 years old and the A/C didn't work anymore, it's probably because their was little or no refrigerant left in the system. Obviously, this system is not made of one complete pipe. Individual pipes are connected by whatever means. There will be small microscopic leaks somewhere, just like in a car and at some point you will need a little more refrigerant. In a standard refrigerator, entire system is hermectically sealed. That's because 1) the refrigerant is not that healthy for you to breathe should it leak and 2) they don't want "Grampa" fixing the fridge, thinking he knows how to do it when he really doesn't, get hurt and then sue the manufacturer. But this system is too big to make of one hermetically sealed system. Refrigerators do last a lot longer than the AC system in a car in many cases. This is, however, because they aren't moving about all the time whereas a car is constantly jostled about as it drives down the road. I imagine that addition of refrigerant in this system would not be required very often since the house is not driving about like a vehicle, but at some point it would need refrigerant added to it.
saisonqwerty hi
Old? Not really, if installation was clean before installation. but it probably should be replaced every few years just in case. Glikol and water are both stable, and the tubing is innert. Nothing should happen.
@Renee Tateground source heat pumps are usually used to heat up building, not cool it down ;) but it is possible with some systems to limited extend.
If the DX does not require additional electricity then what powers the fan that blows across the tubes?
jksatte no additional electricity that would normally be used to power a pump for the coolant is what I assume they meant. In most geothermal units antifreeze is circulated through a ground loop and then ran through a heat exchanger with the Freon.
Not sure if this is cost effective? The ground raises the refrigerant temp from 20 to 30 degrees, only a 10 degree increase, for a lot of money and work.
Can you put the video in si units that the rest of the world use?
Heloooo greeting from INDONESIA . . . .the BIGEST land of it
Wow if that stuff has to be replaced.
Gas?? Does it use Freon? How would that save money? What do you do when you get a gas leak under ground? How is this any better than a heat pump?
So the difference in air temperature with that of the soil (54 F), is the gain?
No, The ground is constant and absorbs the heat as the refrigerant changes state.
So you still need electricity for the compressor and the fan. Also doesn't copper pipe corrode in the ground?
People have K copper or soft copper for the water supply to there house and can last over 100 years this going straight down in a well should do fine with freon in it but make sure there are no connections i mean one continuous peace of copper and with valves above ground for testing. and if solar panels are to turn the pump!!!
Yes but it's all insulated, you don't put it straight on the ground
So basically satan is in hell, and its underground. So my house is heated by satan. Cool, thanks!
Actually heat in this systemt is from the Sun.
😂😂....
Dante has Hell being cold 🥶 so that’s how AC works in Summer 🥵
@@movax20h r/wooosh
Really helpful video but is the temperature in Celsius or Fahrenheit?
if you see next to the temperature numbers there is a small o that means it celsius
MEALIVEUDEAD that means degrees
Fahrenheit
I would love a system like this, but I can't seem to find a contractor here in Hawaii. Is there anyway to ballpark a cost for a system like this? I live in Volcano Village (Hawaii) and would love to have a system like this integrated into my 1920s home w/o losing it's character. Love my old fireplace (original wood fire burning) but would love to have a green solution like this for my water and heating as an option. Would be nice to have these for mold and sanitary prevention as well!
Where your at you need solar panels in the yard and use the electricity for everything.

Its like watching a TV show from the 60s, because they use feet and Fahrenheit, while us in modern countries use metres and Celsius.
Greatest country in the world, the USA ...yeah, right, lol.
So this system is more efficient than a water based one huh.... Hmm...Can I heat my floors and driveway with this system like a water based one?
Mean the heat transfer
You can use inplix instructions to build it yourself guys.
7 foot diameter holes! Wow!!! 1:10
What’s the return on investment for a homeowner
You should take instructions from InpliX website if you want to learn how to make it easily.
Can you do a metric version for the rest of the world? Only American use imperial units now. American scientists use metric too
I think you're forgetting Liberia and Burma. Land a man on the moon and then we'll consider your metric nonsense.
The Apollo missions utilized metric and imperial measurements so I don't know exactly what you're referring to.www.doneyles.com/LM/Tales.html
@@think2wice516 you still believe the lie about the moon missions. Ha! Nobody landed near the moon mate. Repeat a lie over and over again doesn't make it true.
Still the same principle. I hope the increase in attention to geothermal benefits you.
Hi! So you drill tubes of copper into the earth that has some kind of liquid that absorbes the cool/heat from the earth and then its pumped to the house? Is that how it works?
It works like a usual air-conditioning system, but instead of transferring heat to/from the outside air, it transfers heat into the ground.
With plans from Avasva you can make it really easy.
Geothermal Energy Options - How It Works
This is not geothermal, this is ground heat source, and energy is from the Sun. This is actually solar system.
Geothermal systems take a heat actually from earth, aka hot magma that warms up rocks or underground in thin places of the crust, and is only really useful in limited locations. Few well known ones, Iceland and some places in California. But of course there are thousands more of varying economical potential, depending on depth needed, and water temperature, and chemical composition and reserves.
The ground is 55 degrees how does that work
What runs the compressor and the fan???
I was wondering the same thing! I'd assume they would need some DC source like a battery or a solar panel to get it up and running.
devientrazz The compressor runs on electric and that electric could be offset by solar. A Geothermal system is the most efficient way to heat and cool today. Payback on most new home systems is less than four years, the bigger the house the faster the payback.
Christopher Ryan Looks like it's a difference of 10 deg more coming from the ground. The heatpump working alone by itself would compress the gas to 160 pretty easily as well no?
+Jerry G. electricity ..................solar panels?
A motor that will not reduce your electric bill in any way, compressor/AC/Heat pump same thing.
Do you work internationally?
No
That's not how geothermal work at all, You will never send refrigerant to the ground, Instead you use water or antifreeze and a circulating pump, there is a heat exchanger to transfer heat from/to water to another refrigerant circuit that actually has the compressor, expansion valve and a condenser (heat mode) or an evaporator (cool mode), from there a blower that blows air through the condenser/evaporator coils and take the conditioned air into the house's main duct system to condition the rooms.
Please give me the video. Thank you
I have seen a multiple vertical well system fail to make design Delta T. Like not even close. Vertical wells in parallel, up and down the same hole. But the designers were oh so politically correct.
If you using coolent n compressors I don't think youl save much ! What's the difference from a heat pump ! Other than gas for heat ? Ac used fluid n compressors n fans ! You took nothing away !
Buried tubes n fan is the money saver !
#moist
Copper soil corrosion leak repair. No thanks. Might be more efficient but offset by increased risk.
you can learn from inplix scripts how to make it yourself.
You are still using electricity to run the compressor and fan.
53 C !?
Copper is a waste. It corrodes over time! O_O. Had me, until you said Copper....
160deg C is far to much for radiators!! You would burn yourself.
thank you..... Imitation is the sincerest form of flattery. However, it is a copyright infringement in this case.
DIY?
not the best use of so much copper.
a small pump with a battery charged from solar would be a better use of resources.
bazoozoo or wind turbine.
And your bill will be four times higher
Your electric bill may be higher but the over all energy bill drops about 70%, as the geo system units operate at about 18 cents per hour. These are the facts.
I must be stupid.
It uses electrisity to circulate the refrigerant by compression and to run the fans. It uses electricity, You are lying.
Your plan using copper pipe in the year 2020 is a nonstarter the corrosive nature of the pipe is an in Normas enormous negative the plastic is going to land the ground for the next 50 to 100 years without change the copper tubing in 3 to 5 years will have decayed.
Copper come naturally from the ground so it can last for ever. There are still copper pipes in the ground in Egypt that have been there for thousands of years. As long as its done correctly corrosion will not take place. The pros out weigh the cons when it comes to copper vs. plastic.
Just buy an air conditioner.
Its probably better if I don't say anything and make everyone feel stupid
Still has a compressor... still has high monthly electrical cost. Dumb!
