O.P.
I read a lot of good things about Techni-ice iceboxes and bought a 40lt one directly from their website.
www.techniice.com
However, my experience with it has been less than stellar. I have used it a handful of times, and I find the ice melts within a day or so. This past weekend, we went
camping and even my mate’s normal Coleman esky was far better than Techni-ice, which I was very surprised about.
I checked the seals etc. and everything is fine. What I did notice is that when I touch the outer side-walls of the Techni-Ice box, it is cold. This can’t possibly be a good thing as it means the cold is not being retained inside the box and instead gets drawn to the outside, mixes with the warm air outside and gets dissipated. Is my basic understanding of the laws of physics/thermodynamics correct?
I asked this question in another
forum and also contacted Techni Ice directly as
well. To their credit, they replied promptly with tips on how to pack the esky - pre-cool, ice blocks, salt etc. etc. All that makes sense.
What I'd like to know however is when you use your esky - Techniice or other brands -how do your eskies feel on the outside when you fill them up with ice and stuff? Does it feel cold or feel rooom/ambient temperature? If it is the latter, logic will dictate that the insulation is working i.e. it is forming a barrier between cold inside and warm temp outside. This means that the ice inside is isolated and will stay cold for longer. Am I making sense? Can you actually tell whether the esky is filled with ice or empty just by touching the outer side walls?
My Techni ice icebox unfortunately feels cold on the outside when I fill it up. Maybe it is a problem with the insulation or perhaps I got a bad batch. Infact you could tell how much of the esky was filled with ice, as the bottom half, which had the ice bags, was much cooler than the top-half on the outside if that makes sense. On humid days, it is cold enough to cause condensation on the oustide, similar to a glass of ice-
water on a table. I am guessing this is probably not good as the cold is not being retained inside.
Sorry about the long post - I am just trying to get some data points around whether it is normal for eskies to feel cool on the outside, when you fill the inside with ice etc.
Please share how your eskies feel on the *outside* when you fill them up.
