I don't get it.by using AC (or a fridge, or heat pumps in general), you are moving heat from one point (inside your house) to another (outside). why not use that heat to, say, heat water for your shower? why are these systems not integrated? I mean, in many places kitchens are usually put adjacent to bathrooms to make plumbing cheaper, so might as well use the heat from your fridge to get hot water. just have detachable insulation or some shit in the hot water tank as much as possible to avoid heat leaking into your house during summer while taking advantage of it during winter.and if people care so much about the environment, then why not use it to heat water to generate vapor instead of just heating air?inb4>noo this doesn't belong here! only computer software is technology!it is. plus a lot of control tech could be used to manage heat in these systems.pic unrelated
Your fridge doesn't hold enough thermal energy to heat up your shower.
>>109429641they already do this you illiterate nigger. LG sells them
>>109429683that's for large buildings, right? can you post examples? I bet there is nothing for small houses.>>109429679it still could be used as the first stage for a water heating system. plus water temperature is lower than surrounding air during summer, which I guess would help save some energy.

>>109429789You would just be quadrupling your failure points for virtually no benefit. Better off working on tesla coils/towers so we can just skip over the bullshit power sources we use now.
how much heat energy is generated by a fridgehow much heat energy is needed for a shower they actually do use heat pumps for central heating in some houses and it is naff
>>109429641>why are these systems not integratedBecause the complexity they introduce is just too much. The juice isn't worth the squeeze. If you actually sat down and started doing math on what costs what month to month you'd realize this very fast. Especially in the likes of a freestanding single-family home.
>>109430229>>109430050I guess you guys are right, attaching the radiator to a water line and adding a pump is too complicatedoh, well.
>>109430110>One 8-10 minute shower: about 2–3 kWh of heat.>A refrigerator: releases about 2–4 kWh of heat over an entire day.free shower every 2 days
>>109429641You can do this if you get a heat pump boiler (so a boiler with a small heat pump on top, in the US you call them heat pump water heater, Rheem is the main brand).In the winter connect the air hoses in the standard way, in the summer just leave them open. It will do a bit of free AC.
>>109430849Except you need the heat at a specific time and doled only up to a specific amount, so the useful energy added by a fridge would only be a fraction of what you consume.BONUS: it makes the fridge less efficient at dumping heat, thus requiring everything to be overbuilt.DOUBLE BONUS: Every water fitting can break and flood your house.
>>109431055retard. 90% of the planet uses heated water tanks. you think they just heat up water on demand?might be hard for you to comprehend as your brazilian suicide electric showers are the only thing you've ever seendumbass
Why don't you use your refrigerator to cook your food and your space heater as an ice-maker?
>>109431114Yeah dude that's actually how they work. You start draining water out of the tank, could water comes in, and the thermostat kicks the heater on. It doesn't just up instantly, but more power is only wanted at very specific times.
>>109429641The most exciting and "real" outrageous answer here is that corporation has lobbied for their own interests. Though the amount of cuck we citizen get various a lot from country to country. Think building codes (use of adobe in US f.ex), trade deals( DMCA and anti-circumvention), politicians leaning on corporate entities to instigate "real" change (very typical of EU). This answer more of why we generally don't see more innovation though.Another thing is that retrofitting old buildings can be, on the whole (societal) be much more effort than just applying a template building 100 housing complexes. Here there are plenty reasons why houses aren't smart, the biggest one being that microcontrollers and accessibility of "at-home-automation" was harder out of reach not so long ago. You also got to factor in ROI on these very minor solution, which ofte only makes sense if you're doing it DYI for the fun of it or you're a prepper. Large parts of the west live in a cold environment, where heat releasing into the ambient temp of the house is what you want, which shrinks the ROI even more. Integrated solutions makes more sense for extreme environments.What you talk about actually happens in poorer countries, where the ROI is there. Eastern european countries tend to be very entrepreneurial. Polyculture is very big in Southeast Asia. The reason why we are talking about it now is because wealth made us brainlets. You're right though, we should be doing it. If you go back and see how family farms or houses were run, it was basically run like a business and the mindset very different. I think DYI smart houses is making a comeback though, as we get poorer and struggle finding a job in the west. Depends how bad politicians cuck us on the legal stuff.
>>109429641this technology is known as heat recovery and it is used in some larger commercial refrigeration systems (like at a grocery store or dairy). a similar system is used in buildings' HVAC systemshttps://en.wikipedia.org/wiki/Heat_recovery_ventilationif you search for "heat recovery refrigeration" and similar terms you can find more information. bringing this technology to the level you are talking about is a current engineering research topic.
>>109429641>why not use that heat to, say, heat water for your shower?you can but the amout of heat you're moving from the air in your room is very very miniscule compared to the amount of heat required to heat up your shower water.you could hypothetically put the AC heat exchanger inside the shower hot water tank or put the fridge heat there the main reason its not done is its just complicated. its simpler to build fridges as one block that dumps the heat in the room it's in and the AC as just two boxes with a pipe between them where the inside box pumps hot coolant to the outside box and gets cold coolant back.
>>109431213what about an ac that turns you into a jeetshitteropinions/ideas? bro?
The additional system complexity along with its associated maintenance and upkeep overheads isn't worth the savings when you can just throw another lump of coal into the power plant.
>>109429641>maaan, it's so hot!>move heat from house to hot water outside>maaan, i really want a hot shower right now!Said nobody ever.So it's either>tfw your hot water cools down and becomes coldor>tfw retarded anon in underwater basketweaving forum dies of heatstroke from having hot shower in hot weather
>>109429641heat pump water heaters exist.i'm just guessing, but it's probably not worth the additional mechanical and electrical complexity to design a fully integrated system. you'd need additional heater exchangers, piping, etc. to realize it.
