Artificial intelligence (AI) models for refrigeration, heat pumps, and air conditioners have emerged in recent decades. The universal approximation accuracy and prediction performances of various AI structures like feedforward neural networks, radial basis function neural networks, adaptive neuro-fuzzy inference and recurrent neural networks are encouraging interest.

Thus, complex multi-objective problems that require high precision solutions to optimize the cost and performance of ideal RHVAC are solved using artificial intelligence techniques (Mohanraj et al., 2012).
Granted, this is modeling, not implementation, but.
That's great, but they are also installing a majority of the world's new coal power plants at the same time. In 2023 they installed about 300GW of renewables and 50GW of coal.
The kind with guillotines and torches. That kind of protest turns a tyrant controlled kingdom into a democratic republic, there’s no protest more powerful
Using rainfall as a(n inverse) proxy for protests is very clever. Interesting to see how the MLK violent protests actually were counterproductive and increased the republican vote share.
At the time of writing, real-time data suggests that for every kilowatt-hour of electricity Ritchie’s heat pump consumes, it delivers 5.5 kilowatt-hours of heat—a coefficient of performance, or COP, of 5.5.
Double would be a COP of over 10. That's a stretch for an overbuilt GSHP and not even slightly feasible for air-air.
High COPs are usually easy on a compressor as they represent low compression ratios and low differential temps. For example I can hit around COP 7 in cooling on my scrap heap GSHP, with an evap temp around 10C and condenser temp around 20C. That's a high side pressure around 100 psi and only 30 psi of differential, "barely working" as far as the compressor is concerned.
The only way I know to get high COPs is to have an oversized condenser and a way to get your refrigerant below ambient, like evaporative, ground source or overnight radiant so you can get the compression ratio down, unless you know a secret in which case I'm not afraid to burn out a compressor or two trying it out!
I don't rember the details of how it works. I think it just reduces the torque or something? Maybe it doesn't work on newer pumps or they already do it.
Oh I think I know what you're talking about, abusing a minisplit by idling the inverter back too far. Effectively you have a hugely oversized condenser for the tiny flow, under the right conditions like a cool night you can get ridiculous subcooling.
But COP is irrelevant in this case because you've derated the actual BTU to near zero, you aren't moving any refrigerant.
Also yes this will kill your compressor because the minimum speed is set where it will get enough oil flow. Run it too slow, and it won't pick up oil and eventually seize up. You also could end up running the suction in vacuum which is also hard on compressors.
I saw 5 for air-air and was impressed. Then I see SCOP? Oh please. Why not change the scale again to make sure nobody knows what a good value is. Just like SEER on an air conditioner.
SCOP varies depending on environmental conditions!
Real COP or go home IMO. Watts out/watts in, no fudging numbers to confuse consumers again.
Between billionaires having penis-waggling contests with rockets, megacorps slurping up electricity to feed their LLMs, gigantic Bitcoin miners reopening defunct coal plants to power their operations, and authoritarians cozying up to fossil fuel companies, I think there's a lot more confounding factors to our survival than just bloated LLM processing centers.
You are making some hahaha, rofl joke and all. But it's a matter of influence power. France has a decisive input in climate policy. New laws and regulations locally can compel neighborss, they can wager at the european level to make united move toward more ecological stances (like the current ban on new petrol car being sold after 2035).
Europe is such a wide market that regulation applying there can shift entire industries
I don’t know if you’ve ever been to an industrial coast but I assure you, they will do a lot to protect themselves while not doing anything positive for the residents of Louisiana. Oil executives and energy traders in Houston will reap the benefits while Louisiana gets a handful of mostly blue collar jobs in exchange for oil spills, cancer, destruction of wetlands, and climate refugees from rising sea levels.
Answer: yeah. It’ll only serve as another tool of control by the ownership class while upending the system in favor of the ruling class. Instead of labor fighting back to wrest control of our own futures, this only serves to once again serve the capitalist greed of major corporations while leaving us starving and weak. This iteration of “AI” doesn’t take aim at our problems. It takes aim at our humanity. I’m all for liberating us from work. But that’s not what this will do. If it can manage to live up to 10% of what generative learning companies are promising, it only serves capitalism. Not labor.
