-40 °C cooling by CO2
The temperature ranges threw me off as well. I find it hard to believe that you're somewhere where the normal temperature is 50 to 60 degrees C - that's 122 to 140 degrees F!! I know it gets over 120 in many areas of the world, but 140 is pretty rare. If indeed you are in a place this hot, I hope you don't have to spend too much time in the sun!!
