It looks like a heat recovery system that gets built into a wall or window. It looks like it sucks outside air in through the fan on one side, and also sucks warm air out of the house on the other side of the fan, then it blows both air streams through a heat exchanger and finally blows the stale air outside and fresh (warm) air inside.
I think it looks like a really good idea, but I'm going to assume it is a prototype as it is really ugly. I'd guess that it is in a polycarbonate case as a showpiece to demo it so that you can see the inner workings. I can't see that as part of the final design. I'd guess it would be attached to a wall in some way but if they were to prettify it somehow it could go in a window, i'd just be worried about loss of light.
Of course it may be intended for industrial/commercial applications where that isn't as important.
the name window is slightly confusing as it's not intended to let light in, just to ventilate with fresh air as on open window would, but without the huge heat loss. the heat exchanger is reported to be the most efficient design in the world. those fans are 'backward curved' centrifual fans, also extremely efficient. i have the bare heat exchanger and fans here in the house and have to build a case and some electronic controls around it.
Once one has sealed up all the incidental draughts in a house, MHRV is pretty much the next step in making a home energy efficient. there's no point opening windows to bring fresh air in and let the heat out when you've gone to all that trouble to keep the heat in, yet the inside air must be changed regularly for health (and safety) reasons.
i spent a while reading up on MHRV and there are loads of commercial models available, all rather expensive, and almost all with high running costs, both on terms of the >50w energy usage and in terms of having to replace filters twice a year. the heat exchanger in the pic has no filters, but can be taken out and popped in the dishwasher to clean it when required.
I had a look at the website, and assuming I was on the correct one, it looked to me that the system was only at prototype stage. Obviously if you have one it is either an old site or you have an early model of it. It also seemed to say that the system is designed to only work in a single room and that you would need one in each room.
On yours can you run ducting from it? or will you just rely on the air flow to send the heat through the ceiling fans. Mind you I guess that just as a system to draw fresh air in without losing lots of heat it would be worth it.
Be careful when you install it not to put the inlet close to a sewer stack or a chimney/flue. Of course you already know that :-)
