AC On The Blind

Blinds on the windows do nothing but hang out there and shade the room from the sun. Say if we were to add functionality to it, what can we include….k, give it some Solar Power, plus add in some engineering tech, and pesto you got the Blind Air Conditioner! An AC that doubles up as blinds and sources green power from the sun. Design-wise it all adds up, but function-wise and scope-wise I’m still on the fence about it. So what’s your take on it?

    I have a problem to see how this would work. Because air condition works on the principle of temperature difference between inside and outside.
    With this one the heat (you take away from the air) escapes back in to the room and thus not cooling the room at all.
    Its just a fancy ventilator…

  • Gunnar Tveiten says:

    So, where do the heat go ? AC-units don’t actually -destroy- heat you know, they just move it outdoors. AC-units that do not either have an outdoor-part or vent hot air to the outside are physically impossible.

    Also, how is condensation handled ? Cold surfaces meeting warm and moist air leads to condensation, what happens to the water in this design ?

    Last, the surface is about 2/3rds of the window, so for a typical 1m^2 window, that’ll give you at most 650cm^2 of solarcells, but the sun isn’t shining straight in trough the window, but diagonally, and the window absorbs some sun and reflects some, so let’s be generous and say that the sunlight hitting these have half the normal intensity.

    The best thin-film cells in existence can convert 20%, long story short, these would be lucky to generate 30W of usable power. How much cooling do a state-of-the-art AC-unit running on 30W generate ?

    That’s right, hardly noticeable at all.

    Design is fine. That’s useless when basic physics are ignored though.

  • Gunnar Tveiten says:

    Made a comma-error in the above, meant 6500cm^2 of solar-cells. Rest of the math is still good though.

  • Yan says:

    good story telling, but not really look good..
    nice try

  • another great concept. I hope someone can turn this idea into a working technology. 😀

  • design check says:

    half baked… not only for the reasons Gunnar lists, but additionally, it will not retract in a smooth predictable manner with those half moon shapes on the ends!

  • annie says:

    I love this! It is a great idea!

  • Steve says:

    If the technology does not incoporate a direct cooling technology then it appears to be a glorified window fan–Apparently, you would have to take already cooled air from another source and use this to act as ventilation system/fan to remove the heat produced from direct sunlight away from the hot window. I live in a hot and humid climate. So we require to cool and remove moisture from the air. I do like the concept and I like seeing ideas that incoporate green technology. Without ideas and new applications, we do not progress. The application could be expanded to include a supplemental battery bank grid and solar panel system added to the roof-top. When you have really sunny days and a lot of money the system could also be expanded to include peltier cooling. Like previously described the system would have to remove heat on one-side and cool on the other. Peltier technology is a power hog..but during the day with a lot of sun the peltier could be employed to cool during peak heat and sunlight. Areas like where I live we cool most of the year. Even during the winter months we cool to remove moisture from the air.

  • Drew says:

    Neat idea, but it has a few basic thermodynamic issues that would be difficult to resolve; heat rejection would be the biggest problem.

    Also, if cooling air drawn from outside (rather than recirculating precooled air), the efficiency of such a device would be absurdly low, far below the threshold for powering it with the few solar cells. It would probably be a power hog, consuming perhaps orders of magnitude more electrical power than conventional a window mounted AC unit, if it works at all.

    • Drew says:

      nevermind, noticed that it does recirculate interior air.

      even so, the whole power density issue with respect to solar cells would be a challenge.

  • Kyle says:

    You know, as a cooling system this idea is a flop. BUT, as a heater, this could work. Just pull the air through the sun-heated blades and blow it out the top. Convection will go a long way to providing the air movement, but a small solar powered fan would be a great addition. So long as it is cost effective, even a few additional BTU’s of heat will help.

  • If you could get the functionality right, I think it would be a great product. Nice design!

  • Britt says:

    I binged a solar powered window unit, actually hoping to find one… I would have invested in this product had it been available. I think its an excellent idea, and not to bad of an eye sore, given its abilities. Great idea, this is how excellent inventors are created, with out of the box extraordinary ideas!!!

  • Mike says:

    This is a great concept but i am curious if it will be mass-produced.

  • kenny f powers says:

    i see what you did there with the blind air conditioner

  • joe says:

    never ever have i seen a practical design on here… obviously “form beyound function” leads to non-functioning pretty stuff.
    and btw… ever heard of heat-shielded glass?

  • dwindle says:

    A solar panel the size of a car can’t power an air conditioner. This device is also missing 90% of it’s parts, such as the tv sized condenser.

  • Zach Young says:

    Another problem with this design is that there is still substantial space between the slats which sunlight can enter through. The more sunlight that enters the more cooling you need to offset solar heating.

    If you could make this work (ignoring the fundamental physical problems of the design) this would be a decent idea.

    I could see a variation of this idea though. Rather than a cooling system, you could make it into a heating system. The incident angle of sunlight in the winter is much more favorable, and a heating system doesn’t face the same problems with the laws of physics. There could be a fire risk though, and I can’t imagine a solar powered heater in you blinds being more efficient that just letting the sun shine directly through the window…

    A much MUCH better idea would be to simply make the slats 100% solar cells and just tie it into your household electrical supply. I know the power generated would be small and such a system would be rather expensive, but the power supplied would be much larger than if you wasted valuable surface area on a useless cooling apparatus. It would also supply power on any day you had your blinds drawn, even days that aren’t hot enough to justify cooling.

  • Jeremy says:

    What if you want air conditioning with the sun shining through your window?

  • ioanna eloul says:

    how ican learn more in greece for product? which is the price?

  • So many cool gadgets can be useful! They are unique and save money

  • James says:

    So it’s not actually an air conditioner, it is a fan.

  • Hidayatullah Soomro says:

    Are such type of Air Conditioners available in the market and what is its price with which country does it made?

  • deadcat says:

    why do you write in capital letter? they are hard to read

  • Tim says:

    Why is everyone so quick to critic the designs on this site. This is Yanko Design, not Yanko engineering or Refrigeration Mechanics. The designer is just that, a designer. He already said he wasn’t sure of the functionality. But that is up to the client to figure out. Sure it helps to have some knowledge of the product you are designing, but who knows maybe his design CONCEPT will be bought by someone who can make it work… My 2cents.

  • Mtl_loudite says:

    Great idea or you could Open them to heat your house and close them to help keep it cool.

  • jenny says:

    nice……a very very cool idea…..even in the its literal sense….!

  • campbell abeckett says:

    i like

  • Tony Afam says:

    This idea could just work, bravo

  • md says:

    isn’t there water that has to release from the ac unit?

  • Jeannine says:

    I love this idea. For me, in my small space with windows to small to fit a standard air conditioner and that face South – this would be perfect.

  • To stop excessive sunlight and to improve the interior use solar blinds.Ultimate solution to protect windows.

  • Joel says:

    If anything the best approximation of this would be a blackout blind with one solid flexible cell. That would capture the most energy. Then put a small fan on the top to move your interior air around. Or you could daisy chain several large south facing windows and power a very small ac unit.

    I have been dealing in solar day lighting and ventilation products for over 10 years. This would work great in Hawaii. I would love to talk to some one to get more information please…
