Every once in a while I stumble on an idea that blows me away in its simplicity and design. Yesterday on Facebook I posted about a pint sized air conditioner that seems to be small enough to be practical for an on grid tiny house (or one that is producing adequate solar power for 110).
But this morning I started googling and I came across a very interesting post. It seems that we silly wasteful humans have gotten yet another thing wrong.
Why don’t we have single units that take care of our heating, cooling, refrigeration and hot water heating? SAY WHAT?
Did you know that we could be heating our water while we cool? And I suppose we could also be cooling our food while we heat? Even though this will be a no brainer for you science and electronics folks, I had no idea, and I think I am not alone. But the question is… why have you science and electronics folks NOT fixed it so that we have systems that save power and money? We need that!
This morning I learned that during air conditioning, the heat and the cold are simply exchanged. That is in essence all that happens inside these machines. More specifically, in a window air conditioner, the air is put through the machine and the heat both that of the machine and the air are sent to coils in the back and there is a fan that blows against the coils and this sends that air out the window. But the coils themselves are enclosed… so there is no need for this to happen. The coils can just as easily be sent to an adjacent water heater and or a hot tub. (see below video)
The same principal, I think would work for cooling, in the winter the air could, I am sure be exchanged so that the air becomes warm and the cooling is sent to a refrigerator. It would only be during moderate times or excessive cold or heat that one would need to use power beyond that of running the machine and I would hazard to guess that you only need power to cover the loss (the rules of hydrodynamics) and to run the machine.
A system like this would be ideal for a tiny house. Three units all stacked on top of one another like a little birthday cake to take care of our water, heating and cooling needs.
Anyone with thoughts on this? Could it work?
