I´v been thinking and since this is a problem to some loft grow´s i design this . i dont really know if there already exist´s something like this but hey

why not ?



Tell me people can this be a solution to cool the grow´s air to at least 22ºC ?

Cheers

It's just given me an idea of something to draw. Thanks

i think the speed and volume that air travels though the ducting will make it very difficult for the cooling unit to have any effect.

the solution would be to increasing the time the air spends in contact with a coolant, why not look into water cooled coils used in distillation to cool gases?

Say you could cool the air enough entering a box. Could you put more lights in that box as a result, sort of cancelling out the heat issues more lights would cause? Or would it be humid?

would the cooling unit not produce more heat, and hence defeat the object u are trying to achieve?

yes, unless the the air intake and outlet were outside from the loft......and in that case i don't think heat would be a huge issue.

as ludacris has pointed out, this is totally pointless!! the fridge would a) produce its own heat and then dissipate that heat into the room the fridge is in.... so why use the fridge? may as well just vent into the room the fridge is in. fridges aren't magical energy destroyers! they just move heat from inside the fridge to outside the fridge.

all of this doesn't matter anyway, because the fridge's compressor would fail in probably less than a day

Have you not heard of Air Con?

you took the words right outta my mouth

Air Conditioning is refrigeration so you're back to Scraglor's point about relocating the heat, rather than reducing it.

you can buy portable air coolers for 50 quid.
these things do not produce a lot of heat , nor do air conditioning systems or fridges.
not enough heat to make much of a difference , but to be fair , using a fridge to cool air is plain daft m8y.
id love to see the mrs face when she opens the freezer door to get the frozen peas only to see it filled with ducting.

a fridge creates as much heat outside, as there is inside, plus a little bit extra from the fridges own compressor, so if you're filling it with 600watts worth of heat inside, then it'll be pumping out 600watts worth of heat outside!! (or at least as much of it as it can keep up with, fridges aren't designed to shift that much heat, hence why it'd blow up pretty quick!)

Well there's various other ways you can cool down an air stream other than using a refrig cycle.

What is it you want to achieve, exactly and why. If we know that then the opinions might be more constructive. (There's a hosted image edited out of your original post)

Basically you need a heat exchanger, copper piping, radiator etc.. just build an insulated box(with vent holes) , within that box, coil up copper piping, run that through a pump to a header tank (located somewhere where the water will be cooled) in a loop and theres your heat exchanger, all you need to do then is run your exhaust into your box and under your exchanger to transfer the heat from the air to your water and job done......Obviously the more reasearch and technological your box is, the more efficient it will be but the principal applies no matter how simple the setup.
