Interesting, the idea being that the air gets cycled every time you open the door?
And that water has a higher specific heat than air.
Hi. Actualexperience here... it depends on the ambient temperature and how much stuff is in said freezer. So heres a data point: Freezer: normal upper level refrigerator freezer chock full of frozen fish caught on holiday in Alaska. Place, Time: Houston, TX, Late Summer, Hurricane Igor just hit and knocked our power out for 14 days. Findings: We kept the freezer shut and at about 4-5 days the fish was noticeably thaw…
He starts by measuring the temperature in the freezer, but then puts a realistic amount of food in it and doesn't want to let the food go bad. So he makes an extrapolation from the warming between -18 and -11, but immediately points out (fairly) that the extrapolation is not really valid. Then he answers a completely different question - how much cold is lost when you open the door. The answer to that is also quite dubious and of limited applicability.
The experiment I would like to see is this: fill a freezer (or a couple of different types of freezer) X% (where X could be 50, 80, 100) with a mix of different frozen foods, including ice cream, meat, vegetables, cooked meals, bread. Turn the power off. Every day, open the freezer briefly, long enough to retrieve some of your samples, maybe some from the top/front and some from the bottom/back. Then tell us, for a few types of food and location in the freezer, what day did the food thaw enough that you wouldn't want to refreeze it? What day did the food become less than perfect if consumed immediately? What day did the food become inedible?
People can put up with different levels of yickiness so you'd want descriptions more than numbers here.

Why are you answering the question? The OP isn't asking people, it's the title of the article, which mentions everything you've said in your comment.

I don't understand why that doesn't make sense. What you do with containers of water is what doesn't make sense to me.
Water has a much higher heat capacity than water, and obviously much higher density too. By filling freezer space with water, the thermal mass of the freezer goes up, and it will stay cold for longer in a power outage.

Why not cook everything at that point and throw a feast. We've done this in India with an extended power cut.
If their stove and oven are electric, and they don't have, or don't have fuel for, a propane or charcoal grill, then a hurricane could really knock out their ability to cook things.

You missed the perhaps most important datapoint: how often and many times did you open the freezer? Side loaded freezer and fridges are extremely inefficient because all the cold air is let out when you open the door.
By the time we were able to find a gas station with dry ice we were out looking for open wal marts at a 73 mile radius from the house (Columbus Texas). The dry ice was not significant enough to do much more than get the fish cool. It was too late.

From what i'v read, freezers are designed to be placed in ambient temperature greater than +10C. There are specificially designed freezers that can withstand up to -15C ambient temp: https://home.liebherr.com/en/lva/products/household-applianc... A guy on the phone that sells used freezers told me that compressor has some liquid that gets thicker when temperature drops below X and compressor has to work harder. The o…
Why would you keep running the freezer when the ambient temp is freezing?
When we went on our honeymoon my mother in law came around and left our freezer full of delicious meat, fish all sorts. But then inexplicably turned off the freezer electricity switch on her way out.
2 weeks later my little sister cane around to leave us some milk in the fridge for our return. Only to find the entire kitchen wreaking of rotting meat and water and other crap all over the floor.
She cleaned it up without even telling us - plus did I mention she’s a vegetarian and hates the smell of meat.
Top marks for my family that day.
