it doesn't show up in colder temperatures, it just shows up as less energy used for a given amount of cooling. Basically the thing dumps less waste heat out the window for a given amount of heat moved out of the house.

it's easy to miss since air con pretty much inherently uses quite a bit of energy. And as its gotten cheaper people tend to use it more.

Literally just installed a new window unit in my office an hour ago. Old one was several years old and the thermostat never worked well (just a dial, was either full off at "5" even if it was 100F or always constantly on at full blast at "6").

New one has a temperature thermostat and remote, seems to work fine, is turning the peltier off when it reaches the threshold.

The fuck do you guys want out of these except "smartphone connected so it can get hacked and join the botnet all so you can change the AC when you're at work :)"

What really should be innovated on is some way to make them fit better into windows of various types.

I just gave up and caulked the edges in, because I'm not getting fucking bugs in my house.

AC and heating are inherently going to use a lot of power

I mean space heaters are basically the only devices in existence that are literally 100% energy efficient (i.e. every joule you put in will become heat)

AC is just going to be a big power draw because all AC units are Peltier units

It's not like a microelectronics device that can be made more efficient

The most room for improvement on heating and air efficiency in the future will come from better home designs and better insulation.

>>60134919

>>60135808
ah yes open a window to 95F heat outside

I guess third world eurotrash is used to living in sub-Saharan African type squalor

>>60135791
If the outside temperature isn't too extreme for it to work you can use reverse-cycle AC to get heat with (seemingly, from your perspective) greater than 100% efficiency. Use energy to pump heat from the colder outside to the warmer inside, against the way it would flow naturally. Then dump the waste heat from the energy you spent inside along with the heat you moved. Bam, more watts of heat in your house than watts of electricity consumed.

>>60135833
You smoke crack, don't you?

>>60135791
>all AC units are Peltier units
Um, no. ACs use condensers, evaporators, compressors etc NOT peltier units.

ACs are actually are very much more efficient in terms of BTUs per watt, 5000 BTU heater draws 1500w while an AC unit of the same BTU only draws 500 watts

They've become more and more energy efficient.

pic related was taken from: https://www.amazon.com/Frigidaire-Window-Mounted-Mini-Compact-Conditioner-Full-Function/dp/B00IYQY1YI

This baby is able to cool a ~12'x12' room efficiently for only about 3.7kWh a day/450 Wh an hour if used for 8 hours that day. This is assuming you put the thing on full blast with no energy saving features.

A few years ago 5K BTU AC units would eat up to 2kWh an hour so this is a huge improvement in energy efficiency. $13 instead of $55 a month per window AC unit is a huge improvement.

>>60134919

Who the fuck (besides niggers) uses window based AC?

>>60136617
Dude, like any house built in the last 20 years is going to have a heat pump. It's like, standard equipment. They're super affordable these days.

>>60136695
Literally most people. Central cooling is very expensive and only suitable for large homes as they can consume up to 5kWh every hour.

>>60136695
Not like I have any other option in my apartment unless I buy one of those standing ones. Before you rag on me for that no I don't have the million plus dollars it takes to buy a home in this city and I'm not about to move to the suburbs where I could afford the mortgage.

>>60134919
They use a lot less energy now but they're basically all the same except for smart features. Mildly convenient to turn it on 30 minutes before I get home.

they're pretty damn cheap. I bought one for a friend because I would hang out in his room a lot and it would get hot because he had no AC. Got one at a local hardware shop for 100 dollars

>>60135791

AC relies on phase changes to move heat, not electrical properties. AC units could just as easily be powered by gas, but this would make them more complex, dangerous, and inconvenient.

Currently you need like 30 solar panels just to power on your own home without using the grid.

You aren't waiting on solar you are waiting on batteries.

Even if we made solar panels free they would still be uneconomical without wildly better battery tech.

Former HVAC guy here.

With regards to simply cooling better and making them use less electricity, it's not happening. It's stagnant in this regard.

The innovation is currently in using alloys to make them cheaper and use less refrigerant. This also makes newer units less attractive to tweakers looking for copper.

Also using more environmental friendly refrigerant, which has been shit so far as R410A shit's the bed at 43°C (110°F).

how are those standing shits
my bed "room" is just separated from the main "room" by some black out curtains but they do a good job of blocking the window AC, I'm wondering if I should get one of those to supplement it

>>60137049
Meh, you can already buy like 20 car batteries to use during the night or cloudy days. 10kW is a lot of juice and YES I already accounted for the "don't discharge car batteries more than 50%" problem.

>>60137058
>which has been shit so far as R410A shit's the bed at 43°C (110°F).
elaborate, like does it stop cooling efficiently or just stop working?

>>60137102
Rule of thumb: every typical window ac unit will use ~4kWh a day. That's already like $0.50 per day.

I mean, come to Australia then try using you're aircon. 46 Celsius we hit last summer, although currently its only 14 and im freezing my ass off...

>>60137058
Do condensers in home ac units use the same R134a (or something like that) refrigerant that those in cars do? Hasn't that stuff been used in cars forever?

>>60137131
It stops cooling effectively at that temp and just ends up being a waste of electricity to recirculate. R410 was a bad idea, but regs mandated a less toxic refrigerant, otherwise not switching was going to kill the market for window mount and floor standing units.

>>60137218
No.

>>60137152
it's more like
would one of those effectively cool my 50 square foot bedroom

It's fairly dry there though, right? I'm in Florida, and while it doesn't get quite as hot here, the humidity makes it feel like you're swimming when you walk outside

>>60137198
Man this reminds me about having lost 100 lbs a year ago [I'm 5'7" btw]. Now I'm 140 lbs and I get cold as fuck below 15C and 27C feels like the perfect room temperature for me.

It's weird how being a fat fuck changes how you experience climate so much.

>>60137218
home HVAC can vary between R22 and 410 depending on the age of the unit. I know units made after 2010 had to switch to dry charge systems with R410 added on site, but the rules are changing in 2020 to force everyone on R410. So what's going on now is that new window and floor-standing units ship with R410 and HVAC shops are stockpiling R-22 ahead of the rules change in 2020, but that's also driving up the cost of R-22.

>>60137284
What do you think about R717? Should that be used instead of R410?

>>60137326
I think that R600a or R290 will more likely be used, as they are both widespread in refrigerators

>>60134919
The small sized ones they have in Japan are dope. On par with their toilets.

>>60137326
717 is functionally identical to ammonia, and can't be used in consumer-grade HVAC systems because of safety concerns. It's fine for use in industrial refrigeration because of the reduced risk of human contact.

>>60135248
>The fuck do you guys want out of these except "smartphone connected so it can get hacked and join the botnet all so you can change the AC when you're at work :)"

What I really want is for it to have a well-defined network protocol and connect to my home's LAN, so that I can automate it however I want.

If I really wanted to, I could rig an IR emitter that's controlled by my computers and emulates the remote's commands... But really, why not have an actual network cable plugged into my switch?

That way the A/C unit can also send me telemetry data instead of just accepting my commands. Hopefully I'd be able to monitor system health this way.

What should I buy to cool down a room without windows?

Yolo McSwaggitty Swaggins, resident of 101 Swagginsville, Swagstown Falls, New Swagshire, Area Code 367485.

One day, Mr Swaggins (otherwise known as Yolo McSwaggitty Swaggins) was sauntering down to the shops when he stumbled across a swagged out baller, of the Universal Stuntin' Team known as The Swagged Out Ballers.

He proceeded to engage them in some light conversation, or compatriotal banter if you will.

He said "Doth you know the swagway to Swaggsville? I seemeth to hath losteth myswaggy way."

"Fear not young Yolo," the strangers quipped, "You just need to show us a 'dip' and we can oblige you with direction."

Yolo McSwaggitty Swaggins dipped at once and was directed in the correct direction.

>>60141507
It's the return.

It's 71°F near the thermostat, which is probably where your return is.

Your return, which should have a filter, is what draws air to be cooled.

If you're not living in a big house with only one system, then you need to call an AC guy to come have a look at your coil.

>>60136484
Those "ductless" giant wall warts cost about a grand. Saw a bunch of them being bolted onto houses getting serviced by city contractors. Installation produces a lot less wall damage than a standard sleeve box air conditioner; you only have to deal with a small gap instead of a giant hole if you want to remove it.

>>60145481
Are these any good though? Was thinking of getting an AC styled like this. I absolutely hate installing an AC in a window due to it being really scary and nerve-racking. This type of AC looks less troublesome to work with.

I didn't encounter Minisplit air conditonings until I went to Mexico and Japan. These things are amazing, you can get an LG unit that pushes out around 30db at low that can push out up to 2 tons of heat or cold, and it is even pretty energy efficient. They're great as dedicated home office units, and pretty good for small server closets in various deployments to an extent.

If I was going to clean sheet design a new one I'd want;
proper PID loop to keep the fucking temperature exactly at what it should be by means of a remote temperature sensor
Power usage monitoring
Refrigerant monitoring (detects leaks faster so you don't get pissed when your AC stops working)
Ultra quiet high static pressure fan blade designs


And that's it. That's the problem there isn't much to do to them.

>>60134967
or until we start using LFTR

I have an LG model I got for $100. It's only 4,000 BTU, but it's only cooling my room. Came with a remote and it's "eco mode" makes it so the conditioner will hold the room at any temp I set and the air conditioner will click to fan only when it reaches it. We family's home has central air, but with how the duct work is run, my room doesn't get any. The hallway outside my room will literally be 25° cooler than my room. Doesn't help I threw extra money into the pool when my father was remodeling so I could get sound proof insulation and sound dampening drywall. Any heat that comes in my room never leaves.

They're not.

You're supposed to have a big enough system to efficiently cycle the air throughout the whole house with all the doors open.

A two story house should have two small systems to be efficiently cooled.

If you rented a two story house with only one system, then you're an idiot.

>>60150060

>>60146772
>>60145481
The innovation was to use a two hose design to boost efficiency.

The air to be cooled is sucked in and cooled over the evaporator (cooling coil). While you have two hoses that connect to the outside; one to suck in cooling air for the condenser, the other to return hot air outside.

Now the really fancy part is that someone said hey why don't we have the condensate from the evaporator drip down into the exhaust hose and blow it out removing the need to deal with condensate.

>>60155505

>replaces one shitty AC model with exactly the same one


In regards to OP's question, how ACs work is very well understood, we can't really do much better than that unless there is a fundemental breakthrough with how we remove heat from an area.
All we can currently hope do it is increase efficiencies of the various parts within the AC system while cranking up the power all power.

eg; todays AC unit consumes 500w of power, but providers the same cooling as a 1000w unit from 15 years ago

High efficiency inverters, scrool compressors, heating/cooling, wifi/web control.

You mean a mini split? We have had those for a while. Central air is leagues better than a window unit.

I have this AC. It works like shit. That energy reduction isn't for free.

the climate differences between the southern US and northern is pretty extreme

it's currently 80F in miami florida and
in eastport maine it's still around 40F

air conditioning is not really required in the north

Seems like a step in the right direction, but is only 5000BTU.

Call Elon Musk, maybe he'll 'invent' a solar-powered AC system which will collect a water from air at the same time.
