Christophe having mentioned the problem of the thermal buffer of great capacity on another post, I thought about it tonight (you'll tell me, he has that crazy ... that one) and I may have a solution , at least theoretical (I like the inventions)
That said large amount of water, also said great inertia but unfortunately difficult to raise the temperature of the buffer.
Imagine an isolated balloon contained in another balloon, itself isolated and contained in another etc ...
A thermal unit is obtained whose global heat capacity depends on the quantity and temperature of each reserve
If the central part is the hottest, the possible losses will occur to the external volumes, to the last, the least hot.
To warm everything up, solar panel heat pump or boiler, nothing more simple, the water circulates through a heat exchanger coil that goes from the inside to the outside
To draw the calories of the buffer it is the opposite, the cold water arrives first in the warmest volume, until the warmest
The above system has less heat capacity contained than in a single buffer 60 ° but the latter being difficult to heat and maintain at this temperature, there must be an advantage in terms of stability of the output temperature
What do you think ?
