Heat pump powered by photovoltaic panels

[Christophe]

Toff, do you have a reserve of 60m3? it is enormous!

Yes but the exact capacity I don't know ... it's between 60 and 65m3 ... there are some photos and explanations here, I thought you had already seen them: https://www.econologie.com/forums/reportages ... 61-10.html

Yeah at home too it's chilly.
My old men in the south they still bathe in the pool, it's not fair
Regarding the solar heat pump, it's still easier to install an adsorption heat pump by using solar thermal panels. The problem is to find such material.
There are indeed the cellars of Banyuls equipped by Tecsol.
It seems that for the individual (10kW) it will come out around 2010 for 20-30.000 €

Mwarf ... a baguatelle, you put one aside?

The worst part is that it has existed for decades ...

Since 91 for Banyuls and for a very long time for the system itself (1944). http://fr.wikipedia.org/wiki/R%C3%A9frig%C3%A9ration

Ps: great Christophe your water reserve. The exchangers are evaporator batteries or cold room condensers. The best is still to recover the day you have to change one. There are manufacturers of tailor-made equipment in the Paris region (Morgana in Stains) http://www.morgana.fr/

Ah precisely I was wondering what it was like exchangers ... are you sure that's it? They are 3m long, that seems "big" to me for a cold room battery, right? But it's true that they look like the 1st of this page: http://www.morgana.fr/batteries1.php

But I hope I never have to change one ...

Otherwise I would soon make a subject / article on the system (as soon as I have made the plans with DIA, keep in mind I advise you as you make some plans also:
https://www.econologie.com/forums/telecharge ... t4119.html ) and then for the bravest of guided tours one day maybe?

Speaking of price, you who did the internship, for 20m² that would amount to approximately how much per m²? (without labor obviously ...)

I found an order of magnitude:
So 20m2 for DHW and additional heating.
2400 liter and 8000 kWh / year storage tank
They announce 25000 CHF (15000 Euros) turnkey - workforce of Sebasol
and 15000 CHF (9000 Euros) in self-construction (except the balloon)

Or 450 Euros / m2 in self-construction

Christophe, you can say more on the subject ...
How does it exist? In principle, in reality, ....

[PITMIX]

The adsorption machine has been around since 1944, just take a small 12V cooler for a car or a small fridge bar to observe the operating principle.
Instead of a compressor, an electrical resistance is used which heats the refrigerant. Pressure-temperature relationship, the fluid rises in pressure in gaseous form. It is then condensed always at high pressure and then relaxed when it is in the liquid state (sudden pressure drop). The refrigerant used at banyuls is a saline solution. When the solution boils in the solar collectors (instead of the resistors) the water and the salt are separated. A pump effect is then naturally generated because the water is naturally attracted to the salt.

Christophe there are large (industrial) evaporators and even more condensers.
Ask the technical department of the supermarket nearest to you for a tour of the fridge facilities. Especially on the roof of the store.
A 6 x 2 m battery is not uncommon.
All standard fresh produce departments are equipped with a battery of around 3,5m x 0,4m for 3kW. Look in this store for fresh produce. Between two temperature displays there is only one battery.
A standard fridge central made in 120kW. Imagine the size of the condenser.

Thank you Pitmix for this cold lesson!

I thought they were mostly "small" cold units mounted in // ... at least that's what you see most often.

It is still high and this is what I feared because with the subsidies and tax credit this price is closer to an installation where you have "nothing" to do yourself ... It is therefore logical that people no longer choose self-construction ...
