It's a good system.
We engineered, designed and installed it more than 25 years ago.
Have idea . Can you free energy battery cell heat and cold
Hello Stefan, could you share with me then I can earn money. Safety.mohammed.ibrahim@gmail.com, please mail me
@@mohammedibrahimali7798 what does that even mean? Is it code for 'send bobs and vagene '?
This will be ideally suited if this system is installed just next to the u/g water reservoir which can store water from an outside supply or can store water from a system of rain water harvesting. The temperature of the environment beside the water reservoir can be used to have a better ventilation system.
Nice idea
Nothing is free!! Forty years ago I helped build something similar. The air was moved by two 3/4 HP fans that ran 24/7 . Considering the cost of the structure and the cost of electricity the owner will never break even.
I would agree with you except still air excerts more pressure with the right set up an a slight breeze you can create massive air flow. Free.
Clinton Barbee how would i go about. I have no idea how to do it but it seems to be a good idear to implement in my future house.
@@clintonbarbee5093 Not arguing science, simply stating a circumstance
I built one 15 years ago, two variable speed fans averaging 50 watts each (they peak at 150). With a heavily insulated house (one time investment) you will get rid of both a heating system and the power part of the A/C system (you need the ductwork) and their associated energy costs. Average yearly energy cost for a family here is 2000$, I get by with 700. All because of neither heating nor AC.

Very nice elaboration
what is stopping mold and condensation forming inside the pass as hot air enters cool pipes?
Just lay the pipe with a slight slope toward the inlet. You’ll also have to incorporate some sort of drain
I hear they put it at a 3% slope
The air should be looped back from the house since the house is at chilled condition. Constantly pulling air from outside will result in a higher temperature difference across the ground heat exchanger.
MY RESPECTED AND VALUED BROTHER, BE EVER BRIGHT AND KNIGHT. THE REAL HELPERS OF THE HUMANITY.
Looks fantastic, but I wonder how effective it is at cooling compared to a standard AC system.
It is able to be very effective in case of appropriate design. Many times not proper design kills the effect and the user is not satisfied.
Christopher Clarke the wondering has come to an end now. 😃
You get ”free” additional energy from the ground. That's the point. The rest is the same. You can add an AC system or not. For most cases, I’d recommend an additional AC system.
Not really sure what you mean by effective by the way. 😁 I guess you think in terms of money if you’re talking about effectiveness right? If so, you should consider such a system.
explain please what instrument you are using for pumping hot and cool air in the building...
An ventilator.
Just an impeller provided fan in outside pipe
This is a basic animation made for those without an understanding of mechanical systems to understand better, not a technical tutorial for engineers, suitable 3D modeling. I'd suggest buying books or find a more detailed and technical tutorial, or discuss with an expert.
what will be pulling the moisture out of the air? if you don't mold will be an issue.

Good Morning! Can I use excerpts from your video to put on an architect's reels talking about a Canadian well?
Yes, you can.
I love how the air moves diagonally from one pipe to another 🤣 smart air.

What is the average cost? How much can that vary? How much can that cost vary when installing to an older home? Where can I see the data on cost savings over time? What are the risks?

if i wanna install in my house what should I do
I am much interested in that kind of setup but the thing is calculations about everything and that can be done with ultimate solutions like uv light cleaner or any other simple n efficient solution.
what I am scared off is the temprature as the ground water temperature is not too above the normal temperature I am in Pakistan..
It could better explanation in video because we aren't understanding how ventilation systems work inside house. How air flow transferring outside inlet to inside house.
I m from India, i wanna know how much it will cost for 3bh house..plz tell
Whom shall I contact for installation, plz let me know..
What about condensation in the underground heatexchanger?
That's my instant concern here. Joe Lstiburek made this mistake years ago, and talks about it in the context of psychrometric charts.
1) uv light could be used to fight with mold,
2) air from those pipes may not necessarily enter the interior, instead it may swap the temperature via heat exchanger box and get excreted outside.
in other words, ideally you would need 2 heat exchange boxes for two stage process: at first you take air from outside the wall and exchange thermal energy with the air from underground, then underground air is dumped outside while the fresh air goes to the second box where it exchanges heat with interior air going into exhaust.

@@NickMWise 1:32 they talk about their filter system, if you want more details, you are free to click on their link. And later on they talk about mold elimination. Again, you simply didn't listen.
What is the max temperature in which this system is effective? I live in New Delhi, india and we have temperatures 42-47 degree Celsius, would you recommend the system?
It is high cost investment at initial but temperature maintains at every time equal throughout the year in 24-26c

How much it will cost and can it be installed in already constructed house .....
...thinking...hot air moves up due to buoyancy...how much time does it take for air to exchange heat with an environment...?
I'm just asking out of curiosity: Does anyone know if these systems can vary/regulate things like the air humidity of the pumped-in air? Or if they can vary the air-flow to different rooms? Or if these can work with room sensors which measure air quality and vary flow accordingly?
This system seems pretty simple. I could be wrong, but I get the impression this would be more expensive to install than standard air conditioning, yet not as flexible.
You could, with zone controls etc but this is crap. The HRV has been long in use, and they add a water collecting ground loop and think its new and exciting. There are reasons why its not code to do it this way
What are the pros and cons compared to geothermal, which uses a liquid closed loop? That is more common than heating/cooling incoming air.
heating in the winter will need supplemental help heating, this won't be near enough in a typical cold winter.
Instead of just 3d computer design...Should have shown actual Installation working at a model house.
that would be a big expense for a startup that already has cad models of all their parts. this video probably cost only $1k.
If you look here you will see how fresh the air is 😂😂👍
Is any presence in India ?
Could it be better if air intake is kept at roof level?
Take in at the shadow site of the building would improve a stable intake temperature
without adjusting continuously with every cloud or taking in air from an extreme heated
sun spot .
But ofcourse you could place the intake higher up when you take notice of these basics.
Be aware also of condense or other ways that water can collect in the ground tubes.
Let them colect the water in a place where you could easily place a level pomp for removal
Of excessive water in the ground system.
If possible you can place a small diameter pipewith a sifon to get rid of the water in a well
Or open sewer chanel down hill (example)

This technology is very good ,is this available in India...
Does the ground continously take away that much heat? Won't there be a decrease in the rate at which heat is extracted after system is operational for a few hours owing to the reduced temperature gradient and slow conduction.
Edit: Why not insert the heat exchange pipes in a well for cooling purposes.?
We count heating and cooling efficiency after system reach (almost) steady conditions - it means after several hours of work, the temperature gradient is constant. Almost, because in real it never happens. Anyway the error is negligible.
Why not insert the heat exchange pipes in a well for cooling purposes?...they do, it's called a cooling tower.

Good job hemant sharma.. Keep it up.. Hehehe
Once per 5 years it's good to rinse with a strong stream of water. You have to get (leave) acces to the pipe incoming into house.
@@Ground-Therm Thank you
Dimitris Andreou our system runs without maintenance for about 25 years now. We haven't thought about cleaning the earth pipes yet.

Will this work with shipping container homes
Yes
How deep you have to dig the pipes, and how much energy the system consumes? Now much is not good enough. How many wats it takes? How much it cost to purchase or you sell it with installation costs? Do you supply to places in Lubuskie?
1) below the frost line. Usually 5-8 feet down. 2)The energy would depend on the size of the system. 3)The energy would depend on the size of the system. 4&5)I would suggest contacting the company directly.
For my compact and well insulated house I DIY'd one, has been working for 15yrs now. Pipe 15cm/6", 50m/yrd long as 2 parallel line, slope 2cm 3/4" per m/yrd at a dept +/- 3m/yrd. Energy use is one 50/100ish watt fan, it pays to oversize a variable speed type. There is a lot of flexibility size-wise there but a lot depends on the dig. There must be a slope for condensate to drain to a lowest point, with a few slits over a gravel drain. Because of this drain you must stay above ground water. The inhouse system as shown in the video is a whole other kettle of fish. It's ok in a new house but rather tough as a refit. Power consumption there doubles as there are two fans needed now.

I am in Jordan and I am interesting in this system
how I can get it
Wouldn't air coming from inside the house and from outside of house while interacting in the exchanger, pollute the fresh outside air ?
What they're probably describing is a Heat Recovery Ventilator (HRV). In summary, no it does not because the air actually doesn't mix together in the box, it's just a convenient model they used here. The box itself is a heat exchanger of some type, e.g. using heat pipes or thin metal plates, and the air is actually going through completely separate channels through those heat exchangers, so the fresh air stays fresh but the heat between the incoming air is brought closer to temperature to the outgoing air. Such devices can often exceed 70% efficiency in matching the incoming air with the outgoing air, so despite how simple the idea is for this device, it's an exceptionally effective way for you to prevent heat/cooling loss with the fresh air coming in.
They also have Enthalpy Recovery Ventilators (ERVs, sometimes misnamed "Energy" Recovery Ventilators) which have a semi-permeable membrane which allows humidity to be exchanged as well (again, without actually mixing the air itself), which is super important in high-humidity environments (e.g. southern US states) because you will "get more" out of cooling your house if you can reduce the humidity (using a dehumidifier, for instance), and retaining that reduction in humidity means huge energy savings without a cost to comfort.
Please use live model to know whether it's feasible
Great idea! I wish you were in British Columbia Canada. Cheers.
how was this animated... which software?
Veeru nice
in such a ventilation system, a huge amount of condensation and bacteria is formed!
Inner layer of pips are covered with antibacterial agent (silver based). Condensation is collected and pumped out from condensation shaft.
Could you not attach air filters on the registers to solve this?
What about mold inside the underground tubes

..good idea. but not friendlymoneyuser.
I think this not a successful idea because hot air has light weight and always goes up so just make the system opposite direction. I mean Cool air release pipe at floor and the hot air receiving pipe at top. Also add a converting module for winter.
It is fan driven, so the air is forced to go where you want it to. But I still agree that convection should play a part. They should be pulling hot air from the tops of rooms which is where hot air is going to be.
so any outdoor orders will be sucked into your house. and the house would be very positive to the outside, which isnt such a bad thing.
The HRV would keep pressures equal. Same in as out. Its still crap, the ground loop will fill up with condensate

Brett Moore well other than Sunlight, preventing mold on the inner surface is a good start.
@@plumsmuglers not sure of your response but with the silver lining a electrostatic charge could be used,to prevent any dust buildup too
Brett Moore It would need that, because a coating would be nullified if any significant dust were allowed to build up on it, whereas UV Light is far more forgiving.

Sir we have basement
this is called a Baghdad air conditioner.
Hmmmmmmmm humidity will probably condensate against the cool inner pipe metal. Condensation within the pipes might cause microbe growth. UV lights might hinder microbe growth though.
No chance for microbs - all internal layer of tubes are protected with silver agent - anti-bacterial and anti-fungi.
Hmmmm, this is an very ancient technology & numerous countries have looked at it in modern times.
For example: Earth tubes as heat exchanger for geothermal ventilation / AC / cooling and heating passive house ruclips.net/video/l4nMsHqCTeI/видео.html
Microbes are absolutely everywhere & at best their growth might be retarded but never eliminated. Really, I can only assume the only practical reason why this technology is not used universally is the potential for microbe contamination. So I plan to use a flexible corrugated ducting (with anti-microbe coating, LED UV lights, etc) and simply make it removable/clean-able/replaceable/inspect-able/etc.
Pls consider making your design open source (note there are many types of open source licenses; fossbytes.com/open-sources-license-type/). This allows folks living on a budget to potential use your system. Worry not, since rich folks are too busy/lazy to make your system for themselves, you'll still get tons of business especially in the US. If you manage your company well, cheap knock-offs won’t really hurt you much. Also being open source, you just might unite all the good work all over the globe in this area. There have been a lot of work.
Here's open source in a nutshell:

hello mold.....
Wait until one of those tube under the house gets a joint crack and the entire system fills with ground water.
There are negatives to all systems. Rodents in your attic eating through your AC tubing is equally as dangerous.
I don't have rodents in my attic, and if I did, I can do something about it. All houses have water under them, nothing you can do about that. Nor can you do anything about the movement of the ground or your house. Nor can you repair this when it fails.
Build above groundwater. It is a very essential piece of info before you get your shovel out. Slope the tubes, add drain slit at lowest point over gravel bed. This will get rid of the condensate. If groundwater happens (I have it very rarely if a winter is really wet) make sure that your lowest point has easy access, it pumps out in a minute with an ordinary garden pump
