- CSIRO has invented a new three in one solar air conditioning system that provides hot water, cooling and heating.
It works by using heat from the sun and employs both desiccant and evaporative cooling technologies.
See how the technology can work in the home.

So, basically, a swamp (evaporative) cooler that works in humid areas. Seems like that desiccant wheel would have to be enormous to work efficiently for a whole-house system though.
Hi Michael. An indirect evaporative cooler incorporates a heat exchanger. It draws in fresh air which passes through a dry channel where it is cooled without adding moisture. Cooling is provided by the evaporative cooling effect on the wet (cold) side of the heat exchanger. The extracted moist air from the wet side is vented, so it’s only dry cool air that goes into the building.
What is the delta T. In other words if the room temp is 75, what will the supply air temp be as you typically need a 15 degree drop in temp to actually drop the room temp in a reasonable amount of time.
i knew solar powered aircon would be a thing sooner or later. this will also put less stress on electricity grids during heatwaves and reduce the chance of blackouts, excellent work
Wow! Great! Please come to Buenos Aires! Your technology is dearly needed here.
Excellent thought. Very much desired for India. We have Sun throughout the year !
innovative product
Is it possible to buy this in India, State of Kerala?
Please let me know
FYI, radiant cooling which is very efficient but still needs a separate dehumidifier to dry the air. So an effective solar power desiccant wheel dehumidifier would be useful for many applications.
Very much needed in india
I want to build this system now please support...
No problem. The desiccant materials we have tested include silica gel, zeolite and polymer. All work, some better than others.
An indirect evaporative cooler that delivers cool dry air, the most critical part in the system, and it does not exist. Those desiccants you tested are little packets they package with electronic products that say "Do Not Eat", and I'd like to see how easy it is to remove moisture from them if you can.
@@charlestaylor3195 Dessicant wheels are in widespread use already.
Heh. They use industrial sized packs (think 2kg bag) in aviation to keep engine parts dry in storage. Used desicant bags are microwaved to remove the moisture and then re-used.@@charlestaylor3195
There is no fixed limit. It depends on the ambient air humidity (more moisture is removed from more humid air) and temperature, and also the temperature of the solar heated hot water (hotter the more dehumidification).
Whats the point is saving emssion if ya just gona open a new coal mine every other year!
@@jimbob-jn6jz Less you need to consume less you need to open mines ?
@@AutoNomades this system would be much more efficient than the present airconditioning tech. We need some kind of breakthrough in solar panels though, I feel like this technology might be suffering suppression because it might disrupt society, Imagine abundant energy... for everybody something like that could even break capitalism logic of scarcity...
Just like Beyond 2000. Sounds exciting but wait 50 more years before you can actually have it.
Always love these sorts of videos. Thanks for posting it... I started to do videos too, but never know if I can measure up to the better stuff out there lol!
The desiccant material stays damp all the time, as 2nd compartment gets humid air from outside. I don't see any fans recirculating air from the 'hot water' pipes, unless the air is isolated there to blow into the desiccant, it will be humid as well. You have to have dry, not humid air to start with to dry the desiccant.
they cant show everything in the video!
There's one area I worry about with this. Air quality. The desiccant wheel is cycling between both chambers, and it's picking up particulates from the air in both. Which is then being recirculated through the house.
Correct me if I'm wrong. But besides the fact that the dessicant wheel itself is already hot, doesn't the dessication process itself heat up the air anyway?
Dessication and evaporative cooling are both just the processes of converting sensible to latent heat and vise versa. When you pass the air through the dessicant, it loses water vapor but the water vapor has to release energy to the air to condense to the dessicant. Likewise, when water vapor is evaporated by the air, the air experiences a loss in temperature as the water has to absorb energy from something to turn into water vapor. In an ideal process, the enthalpy or total energy of the air (in the form of sensible and latent heat) has to stay the same.
Given this, isn't the addition of a dessicant wheel redundant then? The decrease in temperature that can be attained by the air was already dictated by how saturated with water vapor the incoming air is.
(energy) to the incoming outdoor air.
Most energy recovery devices transfer heat (sensible) energy only. An Enthalpy Wheel allows both heat (sensible) energy and moisture (latent) energy to be exchanged. The Enthalpy Wheels are usually made of porous materials to increase surface area which aids in energy transfer. In most cases a matrix core material is coated with a desiccant such as Silica Gel or other molecular sieves to increase latent transfer.
The Enthalpy Wheel, coated with a desiccant material, is rotated between the incoming fresh air and the exhaust air. Heat and moisture are given up to the wheel. When the space is in the heating mode, the heat and desirable humidity is used to pre-condition the incoming, cold, dry air. In the cooling mode, the incoming air is pre-cooled and dehumidified.
Because the cost to remove moisture can represent 30 to 50% of the cost to condition air, substantial additional savings are available with enthalpy wheels over conventional air-to-air exchangers.
Summer & Winter Energy Recovery Wheels
It's caled a swamp cooler. Works great in low humidity, not at all in high, plus has a fixed temp drop of about 25 degrees, so if it's 110 out you can get to 85, better than nothing.
yes, it is a swamp cooler... but you didn't notice what they were doing to the air BEFORE it got to the evaporative cooler - they are DRYING it. So, they pre-treat the air by dehumidifying it before sending it to the evaporative cooler (which adds humidity back into the air)... the result is cool air (colder than regular swamp air), that does not have an increase in humidity. I think I have seen an efficiency gain where the temperature drop is about 35-40 degrees (F) instead of just 25 degrees, as you stated.
Why are we not funding this?!?
asking myself right now, 7 years passed and this kind of technology is better than the actual and do not hit the markets, is that being suppressed?
no water pump required as the hot water system is equipped with a circulation pump. Hot air or cold air to house depending on time of year minus the humidity.
This 3 in 1 system could be dramatically improved by new recent technology breakthrough of Valeriy Maisotsenko and our R&D team. Look at M-Cycle providing 100 deg. F Cooling Demonstration - 60 deg. Celsius air cooling. M-Cycle is well-known in Australia. Using M-Cycle your solar-powered system could be Siberia-cold and Sahara-hot @7hvA
FYI, radiant cooling which is very efficient but still needs a separate dehumidifier to dry the air. So an effective solar power desiccant wheel dehumidifier would be useful for many applications. So when will it come to market?
Only works with the Metric system.
Relevance???
The CSIRO produced printed thin film photovoltaic cells about 5 years ago too, still not on the market as far as i can tell... There is and has always been a major disconnect between researchers and manufacturers.
They might well just make these videos and hope for a company to make them a sizeable offer, where as most companies would prefer to spend the money on their own research that they can patent.
I doubt it would ever come to market. Modern A/C units based on compressed refrigerants are highly efficient, relatively inexpensive and easy to install.
This is a very interesting solar energy application
I am looking for indirect evaporative cooler providers.
Please bring this to the U.S.! free us from these greedy and corrupt electric companies!
The thermo acoustic cooling is a way more effective and better. BTW, there even better, simplier and cheaper solution, use ground with always constant temperture for cooling and heating.
come on CSIRO WHEN IS THIS COMING TO MARKET??????
Yes, I would like to know that as well, WHEN?
Never. It will always be too expensive for a swamp cooler.
@@unclephil4112 🤣🤣
Amazing product, much impressed.
We have a humidity here of about 80%. Would the cooling be efficient with such high humidity? and what is the lowest temperature we can reach?
Okay, but what if you need to sweat?
There's nothing that's actually cooling the air except for evaporation, which significantly raises the humidity and reduces your body's ability to cool effectively.
And for reference, when you remove water from the air, you also heat it up. that's just a part of the condensation process. So this does nothing.
I was thinking this would involve something similar to an einstein refrigerator, which uses the heat of a flame, combined with liquids that have different rates of expansion and density, to cool the air going into the house. My family had an old motorhome with one of those, but unfortunately I don't think that would have a high enough efficiency to overcome heating by sunlight. maybe if the house was super well-insulated.
I'm so pinching this idea.. thanks for the heads up..CSIRO thingy...
Belize here i come!!!!
Hi Darren. The technology is currently being trialled in select residences. We're hoping that within a few years you’ll be able to have one in your own house.
CSIRO Hi there, is this technology available to buy in Australia yet?
These are great ideas, hope you get partnerships with housebuikders, since it seems like an extensive installation for a house not designed to be integrated with these efficiency ideas
This is amazing! I hope we have this in the US already.
It's basically just an overly complicated, low output swamp cooler (the "air conditioning" side of it) with multiple single points of failure. The heating aspect might work but the cooling is going to be weak to non-existent. Because among other things you have a very hot "desiccant wheel" constantly moving through the cooling side of the system.
Gotta love those Aussies though, they're the kings of over-complication. That's why they do things like use three syllable words to describe something the rest of English language speakers use a single syllable for. "Billabong" vs. "Pond" for example.
Australia's climate is a lot dryer than SW Louisiana, or Florida, but would work great in Arizona...
I don't know about SW Louisiana, never lived there though having been through Alabama and Mississippi in the summer time I can imagine.
Australia has a varied climate, from tropical jungle to alpine forest to desert. I HAVE lived there and it's not necessarily a dry climate unless you're in the desert. Funny thing about the climate there, in say someplace like Queensland -- It varies. There are very dry years and there are very wet years. You never know for sure which it's going to be. It could be droughts or floods or neither. So even more reason not to invest in this hokum because among the many things Aussies are good at, conning people is right up there at the top of the list.
Questions:
1. Does the humdity escape somehow before or after the dessicant material?
2.Is the dessicant a disposable feature, and if so,
3. what is the replacement cost?
4. what is the replacement interval?
5. Is there a chance of mold accumulation over time?
This would be far more effective if it was installed in a passive house (highly insulated, with triple glazing, drawing in air from underground pipes).
Geothermal.
My wife and I do live in a passive solar home, with triple glazing and earth pipes supplying fresh air. The walls are 12 inches or 30 cm thick, insulated with blown-in cellulose. R48 or so. We have R68 overhead, and R36 underfoot. We have no need for air conditioning at all, as all that insulation keeps the heat out in summer. Our summers here in British Columbia are around 30-35C. The house is always comfortable.
Now, I'm not saying our home would be able to withstand the 45C heat of Australia. That's a big challenge for any home designer.
@Salvatore Guidone It depends.. Strawbale houses can be cheap, comfortable and well insulated..
This is effectively a two stage evaporative cooler. The first stage is described in this video where the incoming air in chamber two is desiccated and cooled slightly by the desiccation (the act of removing water from the air medium cools the air slightly). This desiccated slightly cooler air then comes across a typical evoprative cooler (stage 2) where it absorbs more water than normal, thus cooling the air more than a single stage evaporative cooler. The real question is, does this provide better cooling per litre of water?
The answer per litre should be negligible, since I don't think the heat transfer changes much given the temperature of water during evaporation. The next question is does this offer a better cooling per watt of solar energy? You would have to do comparison to solar panels versus this system.
There was a time when government research institutions would release their findings into the public domain and specifically tailor instructions for building their inventions for capable laypeople and mechanics in the general population, specifically farmers, ranchers, and shop enthusiasts. That era ended some time in the 1970s or 1980s. CSIRO -- if you can't find an industry partner within a year or two of inventing something useful, then you should publish your results, and publish plans for citizens to build your devices on their own. You are holding back the progress of civilization by withholding your discoveries.
100% right on. I want to know how they build the 'head' of the unit. The plumbing, Water tank and solar collector anyone can do.
hiii... this project was awesome ... this project when came in market and it only for Australia or all over the world ....
Its seems to be more of a dehumidifier.
Heat Pumps are mostly a dehumidifier too...
Hi, Thats fantastic. Can you refer me to a reputable installer in the Northern NSW / Gold Coast area so we can get more info. Thanks
Yes the process is patented.
Where can we buy this?
Well the first sentence in this video was very presumptive!
Firstly, although I am in SEQld, I have no heating or cooling in my house and my hot water is on the lowest usage tariff and I use very little anyway.
I would not produce 5ton of GHG per decade let alone per year!
This is why I am looking at alternatives for a/c. To keep my GHG to the lowest level!
As I am now in my twilight years and the summers seem to be getting hotter, I have been advised to get AC.
But the extreme power usage weighs heavily on me, so some research is required before summer takes hold again.
ClissaT - On UA-cam there is a Video, "Citrus in Nebraska" and on the Net, 'Citrus In The Snow", where they describe very simple, effective, base Cooling systems, that the person involved, has spent 20 years on Tweaking it, for reasons Different than yours, in part, but getting the Benefits you want! Also, in his case, it's used to warm his House, and Greenhouse, in the Winter!
Install earth exchangers at about 18 to 22 feet in the ground. A constant temp of 54 to 56 degrees Fahrenheit with unlimited amounts of energy can be obtained.
Always cool in the summer and a base amount of heat in the winter. The deeper you go the warmer it is.
Geothermal.
Moron that just trolls repeating Geothermal gets likes lol
FYI, radiant cooling which is very efficient but still needs a separate dehumidifier to dry the air. So an effective solar power desiccant wheel dehumidifier would be useful for many applications.
WTF Feet ? Fahrenheit ? Get with the program. If you want to convey your message to the other 95% of the world please use the Metric system and Celsius.
Dear, Metric NAZI, the is program no matter what you have been told. Your not the leader of 95% of the world so your opinion on this matter is meaningless. And people will keep using the measurement system they are most with comfortable using like it or not.
Kinda like you are just comfortable making worthless troll comments. So enjoy having your "Feet" in your mouth. Have a good day, Sir.
How it will cool the house. Descant wheel will raise temperature minorly. How air tempered will drop, its not explained
WHY I'm TROOLING?
Because the dessicant wheel will need to be larger than the housse AND it will still bring 100% RH inside. Have a look of the explanation. I've include a list of options that will do the work thousand time better than the present piece of shit and at a fraction of the cost.
COMPARTMENT 1 (It will take hours to dry the dessicant wheel and this wheel will get too hot in the process)
1 The hot water will be arround 70*C
2 The air can't be warmed higher than the water temperature
3 The dessicant wheel media can't be warmed higher than the air that has been previously warmed
4 So, this double loss due to heat transfer will leave the dessicant wheel way under 70*C, maybe 50*?
5 At 50*C, drying the dessicant wheel media will take MANY HOURS
6 The dessicant wheel will barely lose any moisture, but will gain temperature
COMPARTMENT 2 (It will take forever to remove any humidity from the outside air on a 50*C dessicant wheel)
7 The dessicant wheel enter into the second compartment at arround 50*C and perhaps 20% less humidity
8 The dessicant wheel will be cooled down by outside air to about 40*C (if it is 25-30*C outside)
9 The dessicant wheel will barely trap some humidity from outside air (10% in one hour been outstanding)
10 The barely driyer air, at 40*C will be cooled in another heat exchanger
11 This last heat exchanger is an indirect evaporative cooler witch need a large cooling water tower outside (not showned, strange isn't?)
12 The indirect evaporative cooler can lower the 40*C air to about 30*C
WHAT DOES IT TAKES TO WORK?
So basically, as per number 9, unles you have a very very slow air flow, you will not get enough duration to get the water removed significantly from the outside air at such a high dew point. I guestimate that it will require a dessicant wheel about the size of the housse, wich is bulky AND expensive!
But this is not the worst...
The main flaws is the last steps. Since the water removal is marginal, it basically only rely on the indirect evaporative cooler, the only working part of this technology. This is not shown since it is not a new technology and it require a large water cooler outside and a large very large heat exchanger inside. Did I mention that an evaporative cooler work only when the outside air is dry? If the outside air is dry, then, there is no point to drying it with de dessicant wheel. If the outside air is moist, the evaporiative cooler is not working. Do you start to get it?
ANY SOLUTIONS?
OK, you asked nicely about a solution?
Once you fired and sue the responsibles for this sensless proposition, you look to what was already known...
More than two thousand years ago...
A Yakhchal was able to cool down enough to create ice in desert. It is bulky and require a little water to evaporate, but it is pretty much zero energy input and it can be made from dirt. This passive evaporative cooling can be used with a heat exchanger. Air passing within a double whall will work just fine or air duct slightly burried under moist sand will work as well for such heat exchanger.
You can also get a "Puit Canadien" to lower the outside RH and to significantly cool the air.
en.wikipedia.org/wiki/Ground-coupled_heat_exchanger
Both technology coupled with a solar chimney will drive the energy consumption close to zero.
You can also plant trees to get more shadow and evaporation from leaves will cool down your yard.
You can also paint your roof and your driveway with an IR reflective paint (or simply white).
You can build an irrigated green roof
You can simply put a tarp over the roof to dissipate the majority of radiation energy from the sun.

Ps Please, take a break, remember that as an engineer you can kill peoples if you cannot calculate things properly... Do humanity a favor and consider going back to school.
What about mold collecting in the fan? Would it not be prudent to have some type of UV light to treat the air before it's being sent throughout the house?
That's what HEPA filters are for. BUT the application of silica desiccant which ADSORBS not ABSORBS MOISTURE is specific to it's own antifungal properties. True it's not fungicidal. But it's the toxin not the mold that kills ya. So it could be ANYWHERE in the duct or house and do damage. Unrelated danger avoidable or not. It is known to pull nitrogen from the air "scrubbing" it so a higher concentration of Household O2 is possible. That can be dangerous. But not REALLY. Iirc 😉
Come to the UAE please?! 😀
I live in Michigan where it gets to 100f or 38c and very high dew point... Winter and very cold -20f -29c. I wanna see it work here
This sounds fantastic! Can it be linked to an existing solar hot water system?
How often does the desiccant disk need to be replaced?
What a simple and elegant solution - well done - make it a compact single unit for easy installation, then it should be installed in every house worldwide by governments and everyone WIN
Tommie le Roux YES I WOULD LIKE TO INSTALL ONE IN MY HOUSE IN THE PHILIPPINES.BRAVO BRILLIANT IDEA CSIRO AUSTRALIA. SEND ME MORE DETAILS.THANKS
Dis you find any more information did you build one love to see
I understand a full scale version of this was installed in a mall in Ballarat. Is CSIRO partnering with any company to actually bring this to market? Given sky high electricity prices, there is surely demand for this?
Long overdue concept. I don't mind so much that it's hot in summer. what makes it harder is that it gets so hot at night that you can't get a decent nights sleep. only 2 hours if you are lucky. one of the drawbacks of evaporative cooling is the celdek pads need replacing. what would the maintenance be like on this system. would you need to replace the desiccant wheel every couple of years. also keeping the spiders out...
main questions are not answered. price, whether it can be incorporated in a flat,or only useful in independent bungalows, how much space does it require. how much does it cool,what is the maintenance cost. dessicant wheel will have to be changed after a certain amount of time,I think. how much power does it draw? so many unanswered questions.
It went over my head. How do you heat water with the sun, bring that heat into the house and make the house cooler? I've used excess heat vented out the roof to bring cool air into the envelope from under the slab. I don't get this.
You should atleast read a little about adsorption/absorption refrigeration/air conditioning before making such stupid statements
And what about the maintenance cost of material that is certainly in heating and cooling conditions? Certainly it will detoriate fast.
you should add links to your products.
How effective is this system in a very humid environment? Does it reduce the humidity of the air as well as cool it?
2:05
The size of system you will need to achieve decent cooling would be enormous..and it doesn't work at night..
It would work at night if you had enough heat stored in a large enough tank.
Great idea. What's the scope of IPR (patent coverage) on this? What would we have to work around to make something like you've shown here?
The big question is where is the heat sink ???? You hide something which is at the end its cooled but how ???
I,m interested to know more. Very much desired for Afghanistan. We have Sun throughout the year !
ill use this - whats the all up cost - we have 3x 2500w electric heaters and 3x 1000w electric heaters in our house and a large evaprotive air conditioner that isn't very efficient this might be the solution for us (and we have an electric guzlin H/W heater)
It's still not clear how it works at night, as major time AC works at night.
Kamalaksh Pai the hot water tank will store the energy which can be used at any time.
how the rapid cooler in the 2nd compartmetn works??? does it works with electricity???????
The indirect evaporative cooler works by using a second evaporatively cooled air-stream to cool the main air-stream. The system uses a small amount of electricity to run a fan that distributes the air and to run a water circulation pump.
@@csiro - So, bc you already using solar thermal heating, that small amount of electricity could come from a solar panel, right?!
@@csiro a second evaporatively cooled air-stream to cool the main air-stream? If you are going to make stuff up, can't you do better than that. Try to make one, then, get some real scientists working there.
im not sure how you can get chilled air from hot water...Without the need for freon, to chill the air
I didn’t know about it either until recently, but it’s the desiccation process. It’s basically the same way sweating works: heat energy is carried off as water evaporates leaving you cool, so basically they are making the air “sweat” by drying it out.
Where does the hot dry air go during summer?I mean,in summer,the cool air is being circulated,but where does the hot air go,which passes through the 1st compartment?
Are you kidding hot air travels through the house during summer because it doesn't work.
been waiting a long time to find out if this is good to market? can we please get an answer....
Scaled down it could be good for an rv.
Has this product been manufactured yet?
do we have some knew on the cost yet?
Can be only be little efficient as it's use dessicant to dry for cooling only little effective mostly on coastal areas as coastal areas real feel is more hotter than the actual temperatures
CSIRO, you said it's patented, so, please provide the patent number and the country covered. Thanks
Until there... sorry but "Thumbs down" for your lack of credibility.
@@alexandrevaliquette1941 CSIRO is the Commonwealth Scientific and Industrial Research Organisation a independent Australian federal government agency responsible for scientific research. Its chief role is to improve the economic and social performance of industry for the benefit of the community. Their credibility is very good, I suspect they just have better things to do than to help people like you who cant use google.
@@roryb1989 Ok, they might have a patent granted, I was just curious. I'm just glad they are not from my own contry because this seam to be a lot of wasted money.... For sure, this scientific principle would work in theorie, but in reality, it will be very week and to slow to be practical unless it is oversized to a point the economic cannot be justified.
I might be to lazy to search on Google Patent today, but I do have some thermodynamic skills...
Ps Let me know when a compagny get profit out of this invention!!!
Alex from Québec, Canada
This technology is long overdue. Sign me up please.
it is also use in winter days? To convert cold air into hot air???
OK, I'm from a hot humid climate, looking for efficient cooling. I searched you tube and this product is wins! C'mon scientists of UA-cam, pick this apart! Find the flaw... cuz I couldn't
flaw is its just a think tank proposal of something I thought of and is decades old and I could tell u why it hasn't been tried before but then I would have to ..... lol
But real issue is getting the discussant wheel dehumidifier function efficiently enough over time...
Everything seemed so wonderful, until I noticed they are in the opposite site of the world.
Make your own it really is super simple idea that's been around forever
That actually made me overly emotional it is that good of an idea..(sniff sniff)
great idea...
When will this system be available to install in our homes?
Make your own super simple
How much the cost of this system please ?
Is there a limit for the amount of humidity in the outside air that would drop the efficiency of this system?
Hi, is it already available as a commercial product for domestic application? Thanks.
Where can we get this?
Why don't you mention price ?
How does it work in real life? does it provide air sufficiently ?
Not at all.. but hey, keep the secret ok?
Our normal temperature 20 to 40 three month winter temp average 18 to 24 degree C and 8 month summer average temp 30 to 45 maximum. I want to use Eco solar heating and cooling system. I want detail about pricing and maintenance price.
good luck
It requires a magic wand to actually work.
heh, i was playing with a similar idea 2 years ago, but based on refrigerators that run on gas flames. So it used amonia
You are talking about a closed loop Absoption chiller. This is just another take on Adsorption (evaporative Cooling).
so, you us an evaproative cooler, but to compensate for the humidity it would add to the air in the hosue you pre-dry it w/ the dessicant wheel??
how about this timelife?10 or 20years?every 20 years to replace a new system?
I don't understand how the INDIRECT EVAPORATIVE COOLER'S work.... How it works ?
They spray water over a car radiator the water evaporates out the other side, air is pumped thru the radiator.......
Dave Miller then the air become humid again, right?
yes
The post clearly states "cool dry" not humid air since it would use a less efficient "indirect" not direct evaporative cooler that is not a mister but is a "heat exchange/radiator unit"...
Just like the condenser part of a heat pump functions, just in terms of cooling the air...
The dry air that flows through the desiccant wheel passes through an evaporative cooler, creating a temperature differential of how much? So there are two fans that move air and presumably some device that sprays water on the heat exchanger in the cooling circuit. Not to be Negative Nancy, but it sounds like two fans and a pump are consuming electricity for maybe / optimistically -2 degrees of differential. Can you share some test results?
FYI, radiant cooling which is very efficient but still needs a separate dehumidifier to dry the air. So an effective solar power desiccant wheel dehumidifier would be useful for many applications.
Evaporative cooler have been used in dry climates for long time so that is not the major issue. What has been missing is an efficient longer lasting, reliable way to dry the air. So the real issue is with the desiccant wheel and the associated systems. Desiccant style dehumidifier have been largely replaced with less efficient heat pump dehumidifier since the desiccant loss their ability to dehumidifier. So the key an effective desiccating system. And the fact is CSIRO is just a think tank and the idea is decades old, even I thought of a variation of how this concept could work. But the devil in the detail. Good luck to someone make it really work....
Thanks
Can you give calculations of this
nice idea
how does it work at night when there is no sun
The air con function of the system works using energy from hot water rather than directly from sunlight. Hot water is heated by the solar vacuum tubes and will store that energy overnight, so the air con element can run more or less continuously, provided the hot water tank is scaled appropriately.
Great idea.
deseo saber cual es el costo del equipo listo para instalarlo en una casa en barrancabermeja santander colombia temperaturas de 33 hasta 40 grados centígrados
I would like some more information please
Are there any way to contact you .. I have a senior project and would like to know more about this innovation ..
does it capable for commercial building ?
Great!, how can I find more information about this solar air conditioner?
There are already plans online for a smaller 1 room design that could easily be made larger for a whole house using pc power supply 4 inch pvc and a rotating desiccant disk on youtube works wonders
Just wondering... is this only available in Australia? Or can this system be adapted in other countries and in larger projects?
Gladys Rodriguez This could easily be adapted to any area that it is designed to work in. The only changes would be motors and voltages etc. I think.
This could also be scaled very well for large office buildings.I can see this replacing cooling towers somhow in the future. Possibly much more efficient and possibly less maintenance.
How did you sell in 2020?
*only works during the day
Is it sold in the Philippines?
