3 weeks of absence in summer: risks for the sensors?




View Atis » 10/03/10, 19:59

Hello,

I am thinking of installing a CESI. I'm still hesitating on the installation (probably Prosolar IDMK 25 or ESE ecosol 2.32, with a 200 or 300l flask).

Well, if I go for 3 weeks in summer, is there a real risk of damage to the "normal" panel? Can I change the fluid for this period?

Thanks for help,

Atis

ask your installer

personally on the material that I built and installed I have a solenoid valve which puts the circuit (the exchanger fluid) in the open air in the expansion tank controlled by a thermostat - there I lose about 5 to 10 degrees which is enough
now I've never had a temperature above 80 ° and
above I can't say what it is
draining the liquid will be worse because you will get in your sensors exceeding 100 ° - I saw the liquid boil during a breakdown on a convection circuit

Bonjour,

Some trade regulations have a "vacation" function.
This solution makes it possible to circulate the heat transfer fluid in the collectors, at night, and therefore to evacuate the calories of the balloon to avoid overheating the next day.

Yes I saw that in the control box but my booster heater is not connected to the control box, are normal?
By cons I also have a container to recover fluid, but nobody explains to me if there is something to do in the summer because I am often absent?

: Shock: I do not understand that the liquid could have boiled while the sensors were drained. A drained circuit does not have any more liquid, right?
If the circuit is drained (and of course the circulator cut, it does not like to run empty at all), I do not see what disadvantage there would be that the sensors exceed 100 Â °. You will just have to wait until there is no more sun to fill the circuits again.

Heat to recover




View dedeleco » 13/04/10, 16:42

There may be some liquid remaining in the sensor by bad luck which drains badly and which therefore boils?
But it would be interesting to keep this summer heat lost for the months when there is no longer any in large well insulated annex balloons (5Ocm of well put insulation should keep the heat for months , the duration increases as the square of the thickness of the insulation a few cm gives a few days and therefore 10 times thicker gives 100 times more or 200 days !!)).
It is possible to store it in soil at a depth of 3m to recover it later in winter !!

It is ecological to lose the solar heat of the summer to release CO2 or burn wood !!!

It would be the econological dream ??

Hello Atis

"Certain trade regulations have a" holiday "function.

This solution makes it possible to circulate the heat transfer fluid in the collectors at night, and therefore to evacuate the calories from the balloon to avoid overheating the next day "


This is my case and it is already a good way.

And if you have the possibility and the mood you can cover your panels with a reflective tarp.

Emptying is prohibited!

A well-designed pressurized installation has a thermal delester in the cellar ... in the form of a small radiator ... it at least does not allow solar energy "outside" ... but j 'admits that it is rather very rarely installed!

But at worst it is the security group that jumps (provide for a yuck evacuation of the glycol to the sewer) ... because what hurts the panels is not the temperature, it is the pressure. ..

I am surprised that we use a "night reinjection" because using energy (circulator) to waste energy is frankly not econological ... and it shows a poor sizing of the system ... :?

Aie

We are talking about just a little absence to take leave, just to have fun elsewhere, and the solution not to have to replace your thermal panels when returning from leave and that the components of the family unit don't snipe you because the panels or the cumulus have exploded and --- shit the shower is cold --- and that ... the only solution you have left is to find the tree for you hang !!!

Little absence? It depends on the point of view, the holidays being generally taken in summer, when the solar potential is the strongest, 3-4 weeks in July / August it represents smells more than 10-15% of the annual production of the solar system ... even 20%!

Some systems are already at the "limit" of profitability ... so good ...

Finally, it is certain that this trick of re-injecting calories into the panels costs less at installation ... than putting a thermal ballast ...

Good Hapéti! : Cheesy:
