/diy/ - Do It Yourself

if you can dig a proper hole then you can AC.

I am a HVAC tech.

I don't think it's even possible. I mean, you could probably nigger rig up a evaporator coil and condenser coil but I doubt they would work at all like a factory made one. And it would be massive labor. Then there's making a drain pan that won't rust and will drain correctly. Getting the right fans for your nigger rigged coils. Either making your own control board or getting a fuck load of relays to run it.

You would be better off with a mini split.

A cooler/ice chest with a large block of ice in it and a small desk fan and you've got yourself an AC system.

>>1655975
If you live in a place with high heat but low humidity, you can make a swamp cooler with simple things like portable fans, sponges, rags, etc. Plenty of designs on the internet, "evaporative coolers".
If you have humidity over 30% you're probably fucked without an actual AC unit of some kind~

>>1655979

What's a mini split bro? Can I buy one from China cus my country doesn't sell any ACs... My rooms not even big, like 10-15 m^2 max. I just don't want to die during next summer.
And I want a proper system not this ice box trash or the fake ACs that work by water evaporation and increase the humidity.

>>1655982
>>1655980

Yeah these fucking suck. And you need to maintain them because water heating and melting becomes a cesspool for bacteria. I just want a small closed loop one, it can also be a bought one and prebuilt but I want to install it myself.

>>1655985
Guess you're fucking hot then m8

>>1655987
>hot

fuck OFF it's been over 30°C in the last days you stupid nigger

>>1655993
>30c
Ok, you're warm. Let us know when it actually gets hot

>>1655975
Either get a window unit or no, it isnt something you can DIY

>>1655999

I cant buy window units in my country lol. Also I can't install them because our windows are large one piece nad not 2 pieced ones which slide over eachother.

>>1656000
Ur fucked then. Leave the 3rd world.

>>1656002

OK guys. I'm coming to the US. How do I get a greencard?
Or is anybody here willing to marry me. I'm a girl(male) btw.

>>1655975
Don't listen to the brainlets OP, there's no difference between an AC and a freezer. The cooling power might be limited but if you can get your hands on a few old fridges it's fairly straightforward.
Might be cumbersome and timeconsuming though, i'd swallow my pride and buy a legit one if i ever needed it.

>>1656005
>Just have a bunch of open freezers in your room
Complete fucking retard

>>1656008
Yes obviously rip out the parts and place the hot parts outside, i thought that would have been obvious.

>>1656004
Show boipucci

>>1655979
>Get a mini split instead

Can you read you stupid nigger? Talk about being useless.

>>1656000
Wat country u at nigga i start pushin ac 2 ur country

lg makes portable air conditioner if you aren't a neet. otherwise you can do bucket of ice + fan

>>1655985
go to a car scrap yard and pull ac from a car

>>1655984
>my country doesn't sell any ACs
where the fuck u live?

The easy way would be to get a small fridge or cooler and put a fan into it.
Or you can make/buy a shitty swamp/evap cooler but don't know how effective those are.

>I live in a country where AC units are not common so I have no other c hoice than to build one myself.
That doesn't mean you can't buy or order one.

>>1655984
>my country doesn't sell any ACs
not even online shops?

>>1656189
He is a spic. They still live in dirt and horse poop. Their IQ is that of a smart nigger.

>>1655975
I dunno man. iv been to some shit tier countries and minisplits seem to be more and more popular the lower the average quality of life

if you cant buy an AC in your country how the fuck are you going to buy the parts to build one?

even if you could get the parts, the tools necessary would cost way more than just buying a unit online and shipping it by donkey to your mud hut

>>1656200
I live in Switzerland you stupid faggots. A refrigerator costs between 200-1000 USD and a AC unit 4000 and more. Obviously I'm not going to pay 4000 and more for an AC that's oversized and overpriced since the tech used in a fridge and an AC is the same.
That's why I'm asking what a good solution is to stay within a sane price range and still not die when I die cus you guys can't stop emitting youjr trash into the air and ruining my climate.
Fuck you americans and FUCK china.

the problem is you are too retarded to use the internet

>>1656275
No, I think you're retarded for doing his shopping for him. Should have just let him die from a heat stroke to remove him from the gene pool.

>>1656266
>Switzerland
Is geothermal HVAC a viable option there? You're asking /diy/ for help building an ac system and have rejected the notion of a swamp cooler. We have a thing for deep holes of small diameter, preferably dug with hand tools. Maybe in this way we can help you achieve your dream of comfort before shit goes totally nuts.

>ruining my climate
>ruining
Ruined, m8. Damage done, too late now, nobody wanted to listen when it mattered thirty years ago and most are still actively contributing to the problem.
>my climate
All our climate, m8. Don't go thinking you're in this alone, we're all fucked already and most don't even realize it yet. Just wait til the superstorms come. Hold on tight, angry planet ahead. Real biblical shit, unless I miss my guess. How long? Dunno. Whee!

>>1656266
Aight i start pushin ac to Switzerland. Wat city should i start, Geneva?

>>1655979
That is possible. All you need is compressor, some sort of coils, capillary tube, thermostat, fans, brazing rods, and some control board you can get from usual suspects.
Problem is that it would be cheaper to get mini split, or window AC. Those would be designed by engineers, and I bet that even cheapest ones would have better COP, than DIY thing.
>>1656266
Search better. Import one from nearby countries, literally $400.
Also, you would 100% need some sort of HVAC license (F-gas), because it is white country and you can't have refrigerants without such license.

>>1656365
https://www.galaxus.ch/en/s2/product/midea-blanc-27-9000btuh-32m-air-conditioners-11510195?tagIds=40-62
Here, 9000 BTU good quality chink AC, only $620.
Don't believe 36 m^2 coverage, it is more like 20 m^2.
You would need:
>rotary hammer drill to make 6 cm hole in the wall
>HVAC gauges
>vacuum pump
>pipe bender (this is important, don't skip this tool)
>pipe cutter
>flaring tool
>oil
>basic tools (screwdriver, etc.)
Also you might need

>>1656266
>That's why I'm asking what a good solution is to stay within a sane price range and still not die when I die cus you guys can't stop emitting youjr trash into the air and ruining my climate.
And you want to install AC? Freons are sooo harmful

>>1656275

The first one is one of these retarded window units where you need a window that has 2 parts with slide overeachother, it's not suited for euroeapn Windows. The other ones are either ones with large tubes to the window (lol) or one that work by simply blowing air to a bunch of water with a fan which are shit and unhygienic as well as don't cool that much and make the room wet .

>>1656366

> pipe bender
lol i can just bend them with my hands im strong buddy

>>1656367
fuck off you american nigger you will pay for creating this mess and making me suffer this heat

>>1655975
Can we get a car and remove literally everything except the AC and bring that inside?

runs of a 12 volt does it not?

>>1656266
Why are you so angry, isn't your life grand? Sweaty little swiss miss, getting your mini marshmallows all toasted. Try being nicer! :>

>>1656377
>lol i can just bend them with my hands im strong buddy
It is not about strength, but about kinking. I trashed my line set, because I thought 90 degree bends are easy.

Also, I forgot that portable AC do exist.
https://www.galaxus.ch/de/s2/product/woods-ac-torino-9000btuh-klimaanlage-10468769
Sure, they are not as power efficient as mini splits (I would say half as power efficient), but they don't require you getting f-gas license (or installing it illegally).
If you would get f-gas license (I don't know how, in my shithole you can buy any refrigerants without any license), you can make thousands of dollars doing easy job for retards (if you consider AC price with installation).

>>1656424
Lol. That portable AC uses propane as refrigerant.

>>1656380
The car AC compressor runs directly off the engine via a serpentine belt.

>>1656427
Propane and butane are getting very popular in small appliances again.

>>1656357
It's not that they can't get them it's that OP is too poor and too retarded to get one.

>>1656377
>fuck off you american nigger you will pay for creating this mess and making me suffer this heat
Get an AC like everyone in Europe does.

>>1656449
>Propane and butane are getting very popular in small appliances again.
True. My fridge uses R600a (isobutane), and it already uses 70 grams of it, which is pretty scary. It is like 1/4 of camping gas cylinder. Also it is scary because pressures are way higher than in your typical gas piping in house.
What is really scary, some fridge manufacturers use pic related on isobutane.
I wonder how much propane does that AC use...

>>1655979
>I don't think it's even possible

I think. noting the fact that there exist communities of people who make steam engines as a hobby, you could do refrigeration as a hobby as well. On that thought I did a bit of googling, and that does seem to exist, like this guy: https://www.youtube.com/watch?v=wYz5-QIky-s Just note, that this is not something you will do with an angle grinder and hammer. Get a lathe and some machining equipment, a brazing torch, etc. It could be a very fun project, just bear in mind you will not save money on it.

>>1656005
>>1656455
Thats my bet. If you want to do it, get an old fridge compressor, make the evaporator and condenser of coils of copper brake pipe, put on a pressure gauge, a small obstruction or needle valve, braze together, fill with propane and enjoy. Can be a fun toy. Just not for 24/7 use.

So. Assuming I dont have a window and don't wanna use these trash water coolers, how fucked am I?

>>1656486
You need to reject heat outside, your choices are through the window or through a hole in the wall whether it's air or a refrigerant lineset

>>1656486
A dehumidifier usually goes a long way in it's own

>>1656515
Dehumidifier also adds heat to the space unless it has an external condenser

>>1656518
The lower humidity will still generally make it feel cooler. A dry 30c will feel a lot better than a humid 25c

>>1656520
I'm telling you that the decrease in humidity will not offset the increase in temperature. I'm not sure how humid it is where OP lives but once you're below 45-50% humidity it really doesn't make a difference.

>>1656484
If you get them in working condition you could just use this setup assuming he has the space for it. Graduation students who leave their dorm usually want to get rid of them around this time of the year so you can get a few for absolutely dumping prices, getting one for less than €20 is not unheard of.
The rest is just a tube that serves as a heat exchanger and a pump and fan and you're all set, no tools or experience required as specified by OP.
But like i said you shouldn't expect more than cooling down a single room by a few °C, you're not cooling a house with this.

>>1656531
Nice troll you almost got me to reply calling you a retard but then I realized there's no way anyone is actually that retarded

>>1656546
nice refutation

>>1655993
30c hot? Lol. Thats 86f a normal nice summer day. Im sure ots probably way hotter in your 3rd world garbage shack. Do you have a window? You should jump out of it.

I was going to offer up some ideas but after reading the thread op is such a fuckin asshole i dont want to. Not that it would matter because he seems to be borderline retarded as well.

>>1656551
I'll start with an easy one then. OP said no tools. Also just with quick math OP would need 4-5 refrigerators to get enough BTU output if they're mid size refrigerators. You would need a stupid amount of tubing coiled in each to allow the heat to transfer. As far as the fan coil it would need fins to have heat transfer worth a shit and about a 200 cfm fan.

>>1656574
>BTU
Oh no, it's retarded.

>>1656581
nice refutation

>>1656583
>designing heat exchangers using imperial
Yes it's a nice refutation, thank you.

Put ice inside glass, blow on it, cool air hits ur face. ur welcome, that will be 499 euros pls

>>1655975
https://youtu.be/R_g4nT4a28U

>>1656593

how meny dollars. I want cool glass with ice pls.

Holy shit you guys are retarded. I actually just wanted an advice on what to buy and here is what I got so far:

> buy a AC unit that doesn texist in your country!!
> i will start importing AC units into your country
> buy an AC unit that won't fit with ur window style
> buy whats essentially a fan blowing on water
> Just put ice in a glass BRO
> some nigger talking about coolants and another one about disassembling car batteries


fucking morons, i can see now why spics are overrunning the US lmao Thanks for nothing niggers

>>1656607
Have fun in your crapshack

>>1655980
Here's the issue - the elimination of heat from the area you're trying to cool. In a freezer or fridge the coils are moving heat out of the box into the room. and AC moves the heat outside cooling the room.

So you are correct an AC is just a freezer with the hot side outdoors. If you can plumb the compressor and condenser outside and refill with refrigerant you're good.

>>1656607
Get ice pack, one of those for coolers when u go out in summer.

Get fan.
Attack icepack to fan

???
profit

the fact that u couldnt even come up with that makes you retarded, nigger

>>1656266
jesus fuck aren't you in the eurozone? Can't you fucking order one from spain or something? so much for free trade huh?

>>1656622
>Switzerland
>Eurozone

>>1656622
Op is too poor for real AC

>>1656607
Hang a wet blanket over your window. When it dries, wet it again. It's not going to be an AC blowing cold air, but it will reduce the room temp. As long as your dew point isn't high, of course. It's easy to do and cheap.

If you had the skills to nigger rig up an AC out of scrap parts, you wouldn't be here, anon. I suppose you could buy a fridge that could fit in your window, take the door off and anchor it to the window frame, but that's rather dangerous to passersby.

>>1656436
New cars/ hybrids run it off the electrical, 12 or 48v. You could belt dive an old one with a separate electric motor but why not get an electric compressor out of a fridge or something

>>1656005
Fridge has really low power compressor, 150W at best, which would give you 450W cooling at best
>>1656484
>Thats my bet. If you want to do it, get an old fridge compressor, make the evaporator and condenser of coils of copper brake pipe, put on a pressure gauge, a small obstruction or needle valve, braze together, fill with propane and enjoy. Can be a fun toy. Just not for 24/7 use.
I think you're better buying pre-made portable AC, if you need real cooling.
If you want to DIY it, I would recommend getting car AC coils, and buy somewhere 500-1000W compressor (R290 or R22, doesn't really matter). Then you can use dancap or something similar to calculate needful length of capillary tube
>>1656581
I use BTU for cooling and watts for heating. Fight me

>>1656627
Hybrids run it of 200+V...

>>1656622
This. I have doubts anyone would ever find out he bought AC from France and installed it without license.

Also, find someone who repairs fridges or sell parts for them. They will tell you where can you buy mini-splits without installation.
Go outside and find someone selling mini splits, idk.
>>1656607
Search it you nigger. I bet you can buy AC in Switzerland. You have fucking CERN here, you must have AC for sale, it is not some African shithole after all.
Check laws. Get f-gas license (I bet it is no more than $500, with training, which is essential to install and service ACs). Make fucking fortune installing ACs. Say they are good for heating, very efficient.

https://www.klimaprofis.ch/daikin/
Here nigger. I don't speak nazi, but there it is.

>>1656662
>>1656663
Op is too poor

>>1656666
Quads of truth.

OP should consider used AC. R22 units will work on propane (even BBQ grade) no problem, just check for leaks internal unit in bathtub full of soap and coil full of gas. Remove flare connectors on internal unit, and braze your own pipe.

>>1656671
I even think you can mix some propane and R22, but I didn't recommend this to you and it would be illegal in US of A.

>>1656655
>I use BTU for cooling and watts for heating. Fight me
But quite literally every cooling device uses electricity, you really mix up BTU/hour and watts instead of just using watts?

>>1656674
Yes.
In heating mode COP is around 3.2, so every watt of electricity would give 3.2 watts of heat.
In cooling mode COP is around 10, because I get 8800 BTU for 800W.

There is even a reason for this. I was born in metric country, so metric we used km/h instead of knots in aviation. But nobody had ACs (well, it is not technically true, but they were measured in metric too).
Then soviet union dissolved, and suddenly people started importing electronics, including aircons. ACs used BTUs, and this is why everyone still refers to capacity in BTU, for ex "seven AC" means 7k BTU, or tiny room. "nine AC" is for a bigger room AC, and so on. While heaters are and always were in watts (1500W, 2000W etc).
It also prevents people from confusing consumption and cooling capacity.
Fried worked in store that used metric for capacity and people were asking shit like "how much does it consume? 3000W seems too fucking much, my shitty aluminium wiring won't handle this".

In any case, 1000 BTU is 300W aprox.

>>1656688
I guess I know now why do Americans use Fahrenheit and miles...

>>1656688
Just checked a wesite from my country that sells AC's and holy shit they're rated BTU/h.
wtf is this shit
>Fried worked in store that used metric for capacity and people were asking shit like "how much does it consume? 3000W seems too fucking much, my shitty aluminium wiring won't handle this".
Can't you just add a suffix like MWe as they do with power stations? Just write kWc or something instead of using an unit that makes no sense in a metric country (a country that is not the US).

>>1656697
>Can't you just add a suffix like MWe as they do with power stations?
Watts would still confuse people. They better use calories (metric alternative to BTU) or joules/hour.
> Just write kWc or something
Well, "WC" would confuse the fuck out of customers, and someone would piss in the AC, especially mobile ones...
>instead of using an unit that makes no sense in a metric country (a country that is not the US).
All manufacturers use metric on AC sticker. (Except units that are exported to US, they use their oz. and shit).

I agree, shit is confusing. At least with BTUs, people don't get freaked out with 5 kW of cooling.

>>1656427
Hm. Why propane isn't used more often in sealed units like window ACs and portable ACs?
COP of propane is high

Plenty of portable units on sale, also you can buy a normal split unit but you are supposed to get some special authorization to install it (depends on where you live). OP is just an underage poorfag.

>>1656775
>but you are supposed to get some special authorization to install it (depends on where you live).
Thirdworlder here. They won't sell you without installation, or it is just illegal to DIY install it without proper f-gas license?

>>1656778
The authorization is for the AC, for some bullshit energy saving you're not allowed to get AC in a residential space without authorization. Usually they will only deliver the authorization for a special reason (sick person who needs it...) but it all depends on the local authorities. This is why "portable" split units are so popular, they don't require any authorization. You can probably buy a normal split unit without problems but if your compressor is not somewhere discreet you'll probably get reported and have to pay a hefty fine and remove the installation. TLDR OP is clearly a tag and plenty of solutions exist if you're not a poorfag

>>1656781
>The authorization is for the AC, for some bullshit energy saving you're not allowed to get AC in a residential space without authorization.
But what if you install an air-air heat pump that has cooling mode? Or such jewish tricks won't work...
Retarded law. Energy consumed by AC is nothing compared to gas you can release.
> This is why "portable" split units are so popular, they don't require any authorization.
This is twice as retarded, because they consume more energy...
Good job Switzerland, good job. Feels good to live in shithole.

>>1656784
>But what if you install an air-air heat pump that has cooling mode? Or such jewish tricks won't work...
no idea
>This is twice as retarded, because they consume more energy...
of course the law is retarted but luckily it doesn't include portable unit. also to be fair you really don't need AC except maybe for a month. The nights are usally cooler and dry heat is nothing compared to tropical swamp weather

>>1656787
>also to be fair you really don't need AC except maybe for a month. The nights are usally cooler and dry heat is nothing compared to tropical swamp weather
I agree. I think having AC to cool your room, when it is just +25 C (on average) outside is not necessary. In my case, I run AC most of the time to heat up my shithole.
>no idea
Anyway, considering that you don't have there extreme freezing, (-5 C is nothing), AC can be used as heat pump, which would save a lot of shekels (if sized correctly), compared to simple electric heat, or burning wood or something.
Shit, why do I try to outsmart your laws, if I don't live even there?

>>1656767
Propane Is flammable and r22 isn't, simply.

>>1656787

I use Tons for cooling and Watts for heating.

This

>>1656874
>I use 12,000 BTU increments for cooling

Don't try to church it up but yeah, 2 tons is less of a mouthful than 24,000 BTUs

>>1656874
Ok, how many tons is 9k BTU?
>>1656835
Unit is sealed, so it doesn't matter.

>>1656965
>Unit is sealed, so it doesn't matter
Implying it will never corrode/leak/etc.
Niggers have been using propane in their car AC for a long time, guess what happens in a head-on collision

>>1656965
>Ok, how many tons is 9k BTU
3/4 ton. Easy peasy

>>1656972
>Niggers have been using propane in their car AC for a long time, guess what happens in a head-on collision
Nothing. Maybe a little fire in front, since condenser would be damaged.
But in car it is dangerous because it might leak in cabin, and you won't smell it (since refrigerant grade propane has no smell), and you will explode if you light up a cigarette. On have a static spark. Imagine having 250 g (entire camping can) in such tiny volume.
>Implying it will never corrode/leak/etc.
Very unlikely, fridges don't leak for ages.
Idk, you can add gas leak detector to every unit, so it goes off, or some smell to gas.

>>1656857
u don't need AC if it is below 25 C outside.

>>1656619
>Attach ice pack to it
this
its a very easy fix

>>1657007
Yes but how do you cool the ice pack back down? Putting it in your freezer? Your room would actually get warmer unless the freezer was outside.

>>1656973
Well nig, this makes sense in India and US, where shit is sold in tons.

>>1657367
>using formal tense when calling someone stupid
How's Google translate working for you?

I have 20+ years doing ac refrigeration. Yes it could be done with frige compressors running in paralell. Equall oil return to all would be a challenge. Frige compressor is about 90 btu at most. You need about 6k btu plus for your shack in daytime. Night would cool faster. You will need condensing and evaporator coils that can handle the freon pressures. Say 800 psi... Acess to salvage components is important. Honestly with little or no knowledge and experience you might finish this project by mid winter. If you get it working the system may last a few months with a blessing and a prayer. The "I need it now" makes this a failure before the start.

>>1657394
Ja, muy bien.

>>1657721
>Yes it could be done with frige compressors running in paralell
Hm....Won't it be easier to have 2-3 compressors connected like pic related?
>Frige compressor is about 90 btu at most
I don't think so, they are 150W compressors, which means it would do 300W of cooling with COP of 2, which is approx 1000 BTU

I will ask here. Why does my mini split AC stinks after I use it for cooling?
I thought I cleaned it completely with peroxide first time, and second with ethanol (tasty one), still stinks if I turn it off and let it sit a little bit.

>>1657721
Now for a soulution. Google ebay import past customs a mini split system. Get a system with pre charged lineset. No torches vacuum pump or gauges needed. You need wrench screwdriver and wall anchors. If you are in a 240vac wall plug country then electric is easy. Cut cords off of stuff and attatch to unit. Make hole in wall for lineset and drain hose. Make wide bends by hand. Avoid kinks. Use crescent wrench to remove kinks best you can. Do 2 45 degree bends instead of 1 90 degree bend.. The precharged linset deal has o ring connectors and blades that pierce end of copper line when you wrench it together. Indoor unit comes with a remote to controll it. No extra thermostat necessary. I recommend Mitsubishi systems. God speed sweaty op.

>>1657740
More coils needed for more green peppers. Might be a down side.

Im a fudd. I use btu for cooling. Watts for heating. I can not dispute your watt ratings because I do not think in watts for compressors. The best I can muster is I belive a frige pulls about 2.5 amps at 120vac running. 2 fans 1 compressor drawing power. Hmmmmm.. W=va. W=120x2.5. W=300. I can see it now. I agree with you on your findings.

>>1657740
I would give it try. It will cool with 2 green peppers. I would leave room to expand ig needed and maximize with a ceiling return for cooling. Fin spacing on a frige evap coil is not very efficient in this application though.

I think he can buy it no problem there, he is just lazy nigger.
I found like 2 places you can get mini split, even though I don't speak nazi. Also I found couple places you can buy portable AC.
>Get a system with pre charged lineset.
Those are impossible to get it anywhere besides USA.
So you would need a vacuum pump and gauges. (Or nigger rig it without any specialized tools, like I did)
>Avoid kinks.
I think DIY units use flexible braided hose, not copper.
But yes, copper is super easy to kink, especially if you had never worked with it. I think it is better to get a pipe bender. Also, I kinked line (brazed to coil with flare connector, pic related) on indoor unit...
>>1657752
>More coils needed for more green peppers. Might be a down side.
Sorta. You need coils for capacity. I think you can take 5000 BTU AC from trash, remove U-fitting and braze pipes there.
> I use btu for cooling. Watts for heating
Me too, except I use BTU exclusively for cooling. Everything else is SI or kg-f.
>W=va
VA, not watts. For watts you need to multiply by cos phi.
Better look on sticker, and see power. Sometimes they use HP, sometimes they use watts.
>>1657757
You would need 3-5 or more peppers for good cooling. Best source of peppers is your local dumpster.
>Fin spacing on a frige evap coil is not very efficient in this application though.
True, I would go for car AC, but shit is aluminium. Old house AC would work, but I think it would be smarter to repair it.

>Also, I kinked line (brazed to coil with flare connector, pic related) on indoor unit...
Sheit, forgot pic.
In any case, you can buy 90 degree flare-flare adapters and nuts no problem. (At least I can, since I found HVAC supply shop in my shithole)

If shit works so good and made from literal shit and fans, why do we still use sophisticated compressors, refrigerants and such?

>>1656377
Bro window AC units are able to be installed anywhere if you have enough brain cells.

And a new one is like 100USD here in the states :)

>>1657937
>100USD
I'm jelly. I could buy window unit and convert it into split under 50 dolhairs.

>>1655975
Anon you can make something which might at least cool down the temp in a room by making a steel box putting water and allwing the water to cool down the air by using a fan

>>1657937
>>1658283
If either of you idiots would have bothered to read the thread you would see that window ACs and swamp coolers have been suggested several times and shot down already.

Also I don't know where you buy your window ACs but you should shop around. $1000 for a window AC is obscene unless it's one of those big 1.5 ton bastards

>>1655999
Anyone who can use a drill without injuring himself can install a split with quick connect couplings and prefilled hoses.

It's just illegal in a lot of countries ... oy, you need a license for that.

>>1658337
>$1000 for a window AC is obscene unless it's one of those big 1.5 ton bastards

That's _still_ excessive. I have a 25,000BTU (~2 ton) unit, about the biggest you can get in a window box, in the living room. It was well under $800.

Ohhhh ho ho ho ho

So someone has to deal with a little bit of heat and is going to piss and moan about it on 4chan. You'll live. Quit being a little bitch and man up.

>>1655979
Could he make one by repurposing the radiators from an old water cooled engine? That's where I'd probably start, but I don't know what the fuck I'm doing.

>>1658393
Now that I'm thinking about it how hard would it be to just rig up an entire car ac to work outside of a car? Maybe OP could find one in a junkyard or something

Nothing to see here. Move along...

>>1658283
WTF is pic?

But what if I make AC, but unironically?
Where should I start?

>>1659080
Learning basic thermodynamics, especially the second law and its consequences.

I use R410A as air duster.
Ofc contaminated.

why wouldn't anyone suggest water as coolant, and using fountain or mist to cool the water which is then recirc into inside house through fan + radiator
like how some massive data centers dump heat into big fountains by putting the condenser there

>>1659111
Split swamp coolers aren't that great.

I have a stupid question and I will ask it here.
What will happen if I replace capillary tubes and check valve with two check valves and TXVs? Will this improve COP in heat pump mode?

I have the opposite question, how do I DIY a heat pump? It is fucking cold here, and I'm not feeling like buying a heat pump, or using electrical heat.
But I have access to junkyard with fucktonn of fridges. Even R-12 ones with gas in them.

>>1655975
Hvac guy here. buy a window shaker or portable a/c. order it in? they are cheap and will do the trick. dont bother building one, near impossible to nigger rig

>>1655979
Get two car radiators, some plumbing pipe, 2 fan, a water pump, some food grade glycol, water, and you can nigga rig the shit out of it.

You could even have secondary cooling if you pipe the second radiator in a cold tank of water to act as a more efficient heat sink.

Ac is just the exchange of heat.

>>1655985
>>1655975
Where the fuck do you live that you know how to speak english fluently but AC units are literally not available?

I can't even think of a country where that would make sense.

>>1659445
He lives in Switzerland. Which makes me fucking laugh. They have collider, but no AC...
I, who doesn't speak nazi or whatever else french do they speak there, was able to find a store where they sell mini splits, a store where they sell portable ACs, for prices that would be OK for Switzerland if you consider that everything there is expensive.
Also it is not that fucking hot there either.

>>1659445
he troll ignore
used make weed greenhouses here til got doxxed by self

>>1659451
he is probably some immigrant from a 3rd world shithole working a minimum wage job based on what he sounds like itt

>>1659614
Probably.

>>1658337
If OP wants to shoot down the most cost effective, easy, and practical solution, he can sit in a puddle of his own sweat.

I even showed how I fit my AC unit into a window that is not even remotely suited to the task.

>>1659734
You can't find window units in Switzerland (and Europe). They are pretty rare, because of window types commonly used. And ones that are sold, cost nearly as much as portable AC, or mini split.
Also, Mini splits are good heaters, why not invest some money and use it as aux heat, especially if you consider it is not that cold there.
