Which perennials (fruit vegetables ...) for a greenhouse?

[Alain G]

That's it I started!

Looking at the greenhouse of cortejuan http://www.lestropicales.com/mesgalerie ... bum&aid=22 which fascinated me enough, I decided to play two birds with one stone by installing a heat recovery using a refrigeration radiator, a circulation pump and a fan that I already had to ventilate the greenhouse, instead of sending the heat to recover in a tank, I send it to the 25 liter pool to heat it and at night it heats the greenhouse !

I reach a temperature of 56C in the sun in the sun and I raise the temperature by 4 degrees at the outlet of the pump for 6 liters of water per minute, to my surprise I keep the greenhouse cooler than the fan alone, the system has been running for a week and I am amazed at the efficiency!

Can someone calculate for me the wattage recovered for 360 liters hours heightened by 4 degrees C!

The thank you box

360X4 = 1440kcal X1.163 = 1674.72wh

You're welcome!

Ha well thank you very much swift!

I can improve by ventilating stronger because I only have a very small ventilator, I estimate that I can double with a ventilator with greater flow but I continue the test with this one if not I will lose too much temperature with ground!

[Alain G]

Good with a pure sun without any clouds at 14:00 I have a gain of 6,5C with a ceiling temperature of 62C and I have to open the door because it's too hot!

I have no choice, I will need a more efficient fan and maybe high and low temperature sensors to start it with the pump and increase performance!

We don't want to, like at www.dlsc.ca to keep this summer heat underground for winter ???

simple sensors like forhorse https://www.econologie.com/forums/post206741.html#206741 and the excess heat of the greenhouse stored underground after simple drilling as done by the Italians:

as well as others in this niche that pierce as cheaply as possible before deeply injecting a very expensive expansive resin per m3:

Much cheaper than stirring all the earth and presto, the greenhouse isolated with bubble wrap (almost cheap double glazing) will be hot in winter with a memory of the summer heat wave !!!

And the Canadians will continue to be ahead of the French stuck in their dear nuclear !!

[Alain G]

My dear Dede, Canadians are far behind on the solar water heater which is much more developed in France, climate forces !!! but the fact remains that it would already be a good step for the economy in summer and we could sell our biggest surplus to the amarikin to cool themselves!

Unfortunately these solar water heater systems we don't hear about it here, when I see the number of watts recovering in the greenhouse, I dare to imagine the energy necessary to even heat the water coming from the earth which is 7 at 14C depending on the period, for a reserve of 180 liters and the loss of the length of the pipes, it is quite a saving at the end of the year!

[dedeleco]

we could sell our biggest surplus to the amarikin to cool off!

Yes, and the Amarikin could often be air-conditioned with the cold of the natural earth, at 13 ° C, winter cold kept underground, just by passing pipes in this earth, without electrical expenditure !!
The economy would be enormous, with in addition the factor 2 of saving oil by driving the amarikins in more economical European cars !!

The idea has already been given but I find it very interesting.

The installation of a survival convertor type reflector. installed in a coherent way you will be able to enjoy a surplus of sun in the afternoon from spring to autumn however winter I am less sure because the house must represent a mask too important

And why not install a dozen 200l can painted in a very dark color in the greenhouse in order to passively increase inertia

If the thermal amplitude with the reflector and the cans is still too large, you can switch to an active system with a car-type radiator and energy storage in the cans, it's just three more pieces of pipe. But if you can do without it is also good

I recommend to all those who want to create a greenhouse to get loaned "the solar house guide" there is a whole chapter on passive greenhouses (with pebble storage, water container, insulated wall on the north side, ... .)
