[foodhacking] [Discussion] cold room build up project

Mon Jun 10 23:46:42 CEST 2013

Hi to all,
Well I think that the hexayurt option is feasible, however many  thanks for the wide variety of ideas :-)

I have got more info on hexayurt and especially insulation material from a friend who is based in Amsterdam, edited excerpt is below.

>>>At BurningMan they made them out of insulation-panels that are sold at DIY-stores for putting in between the hollow walls typically used in construction of houses in america. The same panels exist here in .nl too; but are used to insulate below a roof. They are definately NOT 15CM thick... let alone 20CM (that's insanely thick; not even commercial cooling-cells get made with styrofoam that thick!.. In fact; they're made with these types of insulation-panels ;)

>> The 'isolatie-plaat' they used also at Burningman have a cover of plastic/something on either side that protects the brittle inside (polyurethane) from being damaged by impacts, etc. It ALSO makes it very easy to use airconditioner-tape (thin silver tape used to seal seams in airco-ducts) to put all the stuff together. I am still looking for prices...

>> On the 'thick styrofoam' side of things, (EPS, tempex), i can see stuff of up to 140mm here on Marktplaats.. sheet of up to 2000mmx1200mm at E7.52 excluding tax.

So now I wonder what model/size of hexayurt would cover 10 square meters of usable floor space, how much and what type of material it would need, ideas about costs would be great. I will try to do bit of studying today but it would be definitively good to hear advice or/and have around someone who actually did build hexayurt which is not my case ...  

Still looking for the air-condition unit and someone to "safely hack it" so it cools down to 4-6C for the OHM event.

Sincerely,

FAA

Are we building a cold room or a bikeshed here ;-)

A hexayurt build with 20-40cm insulation material and cooled with
airco's and dry ice will be less complex, not require long waterpipes,
pumps and the dumping of large volumes cooling water. So few moving
parts and no water to leak into whatever is actually is that we want to
store in the coldroom.

But maybe I'm missing something...

This is getting a strong "How hard can it be?" vibe.
