Why did I have to scroll to the bottom to find this? Like, where did you think the removed heat was going otherwise???

that's the joke. i tried to imply it in the title but i didn't realize that in english you call it 2nd law of thermodynamics rather than 2nd rule

It also won't put out much more heat than is already in the room. It evacuates heat from it's interior, heat that was already present in the room. If the room was colder than the inside of the fridge, it wouldn't produce any heat at all. the thermostat would cut off after the temperature equalized and it wouldn't run at all.

When it does run it produces maybe a few dozen watts of waste heat. Definitely not useful to heat a space with.

Would be great for people that love yogurt.

a heat pump oven sounds like an actually cool idea. why is it not a thing yet?

The pic suggests adding a fan but that will actually cause less heat output, since the fridge will be more efficient at maintaining inside temperature with heat removed faster from the condenser. The difference is slight though, since the refrigeration system's waste heat (equal to its power consumption) is a small part of what exits the condenser, the rest is compensating the heat that seeps into the fridge by imperfect insulation (and does not heat your home anyway) plus a little bit for cooling recently-inserted warm things.

I mean, it's AI generated, so it isn't going to make sense lol

if you're cooking on the stove but the fridge is next to you and pumping out lots of heat that heat may inadvertently make your food overcooked.

the startup entrepreneurs have thought this through. give them some credit.

A very "not like that" Cooking Triangle.

And the fov is likely from a hallway, dining, or living room. All weirder choices for a normal fridge if you decide on a separate kitchen. Then again everything in the pic screams unthought-out/unpleasant layout of a western suburban hellscape.

The fridge would actually have to work harder though, to maintain a larger temperature difference between its hot and cold sides. So it'll likely use more energy than the way fridges normally work.

In winter, if it's cold enough outside, refrigeration may not actually be needed. You could just pump coolant between inside the fridge and an external radiator to cool it.

But, now you have a more complicated system that requires more permanent installation into the house, and also has an outdoor radiator that needs to be maintained so it doesn't get clogged with leaves or damaged.

especially in areas with district heating, it's a massive resource we're just throwing away currently.

i want that too. lots of houses already have hot and cold water lines so it shouldn't be too hard. problem is getting appliances to adopt a standard on how to connect to this network

1. Stability. Temperature outside fluctuates, food could freeze or get too warm.
2. Containment. The fridge prevents critters from getting to your food.
3. Location. The fridge is conveniently located in the kitchen.

In winter I do tend to keep drinks outside if the temps are alright, they cool down faster outside than in a fridge anyway.

This was originally what cellars and basements were for. Ground temperature was stable relative to outside temperatures, so it was warmer than freezing during winter but colder than outside during summer. Thus it could help preserve food.

Fridge is expensive, only have one.

Fridge is large and heavy, not worth trouble of moving outside.

Waste heat from fridge go to heating house anyway with efficiency above typical resistive heater can manage before even consider double benefit of also cooling food.

if you're already heating your home, then what does it hurt to have the fridge do a bit more of that?

in fact, the fridge is a tiny heat pump using your food as the reservoir. so unless your house is heat pump equipped, it is beneficial energy wise to keep the fridge inside.

if your house is heat pump equipped, then it depends on how the efficiency compare. if you put lots of hot food into your fridge then you should definitely probably keep it inside.

I see plenty of secondary fridges outside. Rust is an issue though.

You can get fridges made for outdoor use, but I guess those are more for people who are willing to spend the extra money on having an outdoor kitchen.

Real easy answer: keeping a fridge cool during a very hot summer outside requires a more powerful cooling system. Instead most people have a powerful AC since you want the house cool anyway, with a cheaper fridge cooling system

The reverse is also true. You wouldnt want your fridge to require a heater installed in it to keep your food from freezing in esspecially cold winters

In Paris a lot of apartments had a cellar opening on the outside.

Like this one:

Unfortunately a lot of them have been removed since it's much easier to have everything in the fridge at constant temperature and energy used to be cheap.

startup idea: fridge with warm little nook for dog

I can get you half way there with a heat pump water heater.

A lot of newer water heaters use essentially an air conditioner type system to heat the water and blow cold/cool air away from it. Obviously only useful if you have your water heater in an area that can make use of said a/c, but I did and it was glorious.

Theoretically you could use a heat pump to heat water that would generate "waste cold", but heat pumps typically don't get nearly hot enough to heat water as much as a gas water heater does. I suppose one could be made but it would be very difficult, I think. It would need to use the ambient air in your house and suck enough heat out of it to heat your water, and if your house is about 72°F / 22°C and you want water at 130°F / 54°C (which is pretty typical) that seems like a challenge, especially since water is so much denser and has a higher heat capacity. I have a portable A/C with a heat pump and it starts to struggle to heat my apartment once it gets down to 45-50F outside and it struggles to cool once it gets above 95F.
