Outdoor, coin operated soda vending machines keep your drinks frosty cold all summer long but what happens in the winter? Why doesn’t the soda freeze?
I was working outside at a marina trying to save a 38′ yacht that was sinking due to a frozen muffler when this question occured to me. The wind chill factor was well below zero but the cokes were a steamy 40 degrees. A reverse cycle compressor was my first guess but that would have only raised the temp 10 or 15 degrees above ambient according to a hvac guy that I talked to. The sodas would have still frozen.

its like a fridge, a controled environment. and yes, soda will freeze and explode. trust me lol

It probably has it’s own thermostat in there to keep it at a constant temperature, after all, there are vending machines with soup and coffee.

That is a very good question!
Because the volume and molecular weight remain constant, if the temperature increases or decreases the pressure will be affected which will cause the can to explode.
I initially thought that there is enough “head space” in the can to allow for a pressure differential, but if you put a beer in the freezer, it will explode.
To answer your question, I don’t know. I will contact a colleague at Coke tomorrow to find out. I’m curious now. To the point where I will probably lose sleep over this.
