This place in Reno sells dry ice.

This may sound weird but I am flying into Sacramento and buying coolers out there. I was hoping to use frozen water bottles in one cooler instead of ice and the other would have dry ice for frozen stuff. The problem is that I have no way to freeze my bottles. I am flying on the night of the 23rd and heading in on Saturday night. Earlier is this thread there was mention of a gas supplier freezing things for you?

Sublimation enthalpy of Dry Ice is 571 kJ/kg.

Fusion enthalpy of water (i e freezing) is 333 kJ/kg.

Water from room temperature to near freezing ~ 100 kJ/kg.

If you place equal amounts of dry ice and water by weight into the same cooler, your water will become well frozen as the dry ice sublimates.

Leave the little drain spigot open and wad in some tissue into it to let the cooler off-gas and not pop the lid at the hinge.

So, the short answer is buy more dry ice to freeze the water.

My dry ice sublimated way faster than normal this year. 200 lbs was gone in 4-5 days. Most years less dry ice lasts longer. Even 2017 didn't kill it this fast. I'm a little curious as to what the difference was.

Exceptionally warm nights?

Our dry ice went quicker this year too and agree with Ratty, our suspicion was the warmer nights (it took a lot longer for the warm air to cool down in the evenings this year compared to last year).

It seemed a lot more humid this year, if it was then air would conduct more heat from the cooler/dry ice.

Dry ice is a very cool way.

Just remember dear folks, dry ice is frozen CO2. if you sleep in your vehicle keep your cooler outside at night while you sleep and put it in there during the day. Just in case you taped up your car and have a small air leak in your cooler.

I use to have a huge freezer of dry ice at work for packing blood samples. When the freezer was a near empty I had to stick my head way inside to get the dry ice out and you simply can't breath cause there is no O2.

Be safe.

Best to keep your coolers in the shade (as much as possible) off the ground, covered with windowshield shiny covers, blankets, etc. and make sure the inside is packed properly.

Keeping it inside your vehicle would just make it all melt so much faster...
