Heat pump powered by photovoltaic panels

I thought you would have used this:

to place in crawlspace

I admit myself that I had trouble understanding the principle of the salt water machine.
In fact, the salt is separated from the water by boiling in the solar collectors, the water vapor is then condensed by an exchanger (condenser) then the salt is led to a separator from which the salt and the water are recombined.
The attraction of water to salt creates a vacuum in the evaporator which is located just before the absorber. This produces an air cooling at 7-8 ° C thanks to the change of state of the water.

Little Question Christophe (off topic).
According to you for your slab would it not be enough to add "Sykalatex" in your cement and to re-create with this to make it waterproof on each side?

I finally found an article that I had been looking for for some time. It sticks more to the basic subject.
There are indeed photovoltaic solar cells with a 40% efficiency.
Astrolab (Boeing sector) is at the origin.
These are "multi-junction" cells made up of galium, induim and germanium.
They focus sunlight from infrared to ultra violet with mirrors and lenses.
With this kind of panels the world of photovoltaic solar will make a huge leap. What do you think ?

It's good that you broach this point because even if it is not the subject of the subject, I have been "working" on it for a while.

In fact there are 2 sources of humidity:
a) the tampon
b) the crawlspace and the cellar

Against the humidity of the crawl space we can not do much. On the contrary let him "breathe" ...

For the pad: it has obviously already undergone a tight casing on at least 5 of these faces (it's almost a cube, the bottom is just not flat but let's approximate it to a cube). But actually I have been thinking for 1 moment to improve this sealing from above (because I don't want to empty the tampon) At the moment, I don't even know if they have buried the bottom of the upper slab ...

One thing is certain: the different holes to pass the water pipes have not been finished (drilling not cemented) and there must be something forced, but if the upper slab has not been sheathed, it is therefore porous to humidity..

For this, I "found" the following products:

- Sikalatex (or equivalent: hydraulic mortar) precisely (it's an i) but it's overpriced reduced to the surface to be treated (20 m²)
- Liquid tar to apply it is the cheapest solution and I think the least chemical but the tar is made to seal against rain from above and not to resist humidity from below so it may not hold in time!
- Mineralizer is also quite expensive (20 € per liter to make 4 to 5m²) but it is the solution which seems to me the most durable!

There are indeed photovoltaic solar cells with a 40% efficiency.

Well I think we had already talked about it to see the cost of manufacture: the use of rare and precious metals (germanium is radioactive in addition I believe) does not provide a reasonable "public" price ...

hi Christophe

For your reduced cost sealing problem
There is an additive to mix with mortar (cement + sand 0.5 or 0.2) which will allow you to make a waterproof coating.
The proportion is resonable and really economical, if you do not count the time spent spoiling the mortar and troweling
For a large quantity, if you have a concrete mixer it's better (especially less tiring)
The product is easily found in the materials department of DIY stores

Good luck

A+

Thanks looping for the info!

Yes I have also already bought 1 box ... (to fill the holes not to treat the 20m² of slab). It's also made by Sika, it's called SikaLite and 1 kg costs € 5 for 50 kg of Cement. It is marked to mix at 2% so 0.02.

Otherwise, there was also another product in the room: SikaTop 122 is a two-component ...

The notice dates from ... 1983 but it still looks a lot like the current one: http://www.sika.fr/construction/document/nt/nt6200.pdf

I do not know if this is what was used to make the casing but it is possible ...

I realize that we are completely off topic ... so I did this topic: https://www.econologie.com/forums/etancheifi ... t4146.html

That you could have used this type of tarpaulin (which I put the link above), up to 30m3, to place in crawlspace in an insulated shell to make your buffer volume

it's cheap, sturdy and 3 year warranty and it withstands temperature

More the stamp we already have... this is what I understood that you did not understand (or that I explained poorly) so I confirm my "Hu?"

See the photos on the link ... ecological house ...

By cons it can be a good idea for those who do not yet have a stamp, see losses and especially how to recover watts ...
