chicopee, thanks for the tip on cannibalizing the dehumidifier, and water storage tanks.
I've done a bit more research, and am starting to wrap my mind around the project somewhat. As you suggest, when I get a better understanding, I'll make a diagram with humbers.
LittleInch, thanks for the reply.
If I start with that, could we size the vessels such that the hot side is 90 C and the coefficient of performance is > 1?
I have some software I wrote that I'd like to apply to heat moving/storage, for fun.
To that end, I've been studying the vapor compression cycle. This is complicated by the fact that I only have a general understanding of thermodynamics. The purpose of this post is put in writing what I think...
Thanks for the input, guys.
Google's AIs might be in my head, because an article came through my feed about a thermal battery using molten silicon, which was recently commercially released.
Thanks moltenmetal. I have begrudgingly agree that an all electric/forced air version is best, at least to start.
I assume there will be times when I have some excess electric. Of course, it won't be anything on the order of GJ, but perhaps it would make sense to use a wood gasifier to turn...
Thanks, that makes sense a lot of sense. Even without much context, his post actually did get me thinking of a small earthquake we felt in the area a few years back, and Fukushima.
Even paraffin embedded in concrete will give off some toxic fumes if heated enough, and so might not work for...
Thanks, MintJulep
I forgot to bring up that not far from where I live currently a ball field was installed, and somehow the artificial turf had enough lead in it that the field was never used and people in the neighborhood said that lead dust would accumulate on their window sills. If I'm not...
I'm looking into making a thermal battery. I'd like to be able to heat a large block of mass, probably concrete based, to 500 C above ambient. Unfortunately, I don't know much about materials science. I'd like to know more, so to that end I've been reading peer reviewed research on the...
I went ahead and redrew my rudimentary diagram per itsmoked's suggestion. Part way through it occurred to me that there was no longer any way to get thermal energy out of hot water, which would seem to be lower hanging fruit then flue gas, as in the summer there is no need for central heat. So...
itsmoked,
What you say makes a lot of sense. When the novelty wears off, it would be no fun to be servicing the thing. Also, a large amount of PG is expensive whereas concrete is dirt cheap, and holds four times as as much heat by volume, so I could use more of that. It may be possible in...
Hi.
I was reading about different types of thermal battery implementations for small scale domestic use, and wanted to come up with a way to improve on them without adding too much complexity or danger. In the course of researching, I happened across rocket mass heaters, which gave me an idea...
