    No, it's a split ac, the other half is literally out of the picture(hopefully out of tne house)

    Or just portable, single unit ACs. I got one of those recently.

    It blasts hot air through a duct that hopefully you're able to direct outside while preventing outside air from getting in. Also noisy as heck, since the full unit is inside the house, and not as efficient as split units, but they do work...

    while preventing outside air from getting in

    If that worked you'd slowly turn your dwelling into a vacuum chamber :-)

    The same volume of air will enter your home in one way or the other, the important bit is that it's cooler than the exhausted air. In particular you don't want the hot exhaust to recirculate back in.

    Ideally you'd get medium warm air from another room into yours, and warm outside air into an unoccupied room.

    Thank you. I thought I was insane because surely mobile units would have two tubes if they really needed them. Then I got one with a single tube (the only ones available) and found out that no, I am sane and these units work really badly.

    I find mine works fairly well, it's a 12k BTU unit.

    It has one exhaust duct. It pulls in warm air from the room it's in, cools part of it and pushes it back into the room, the rest is used to cool the condenser and that hot air is sent outside through the duct.

    It does have another tube, but it's a small hose to drain the water from condensed humidity.

    It pulls in warm air from the room it’s in

    Until the room is cooled enough that you are using the air you have paid to cool, to cool the evaporator. Portables are shit.

    That's one of the main reasons their efficiency is lower.

    A split unit, especially with an inverter motor, can be 50% more efficient, much less noisy and cool more evenly.

    That said, portable units do work. For people who are unable to get a proper split unit, then don't rule out a portable unit.

    Dual-hose portable ACs avoid the vacuum problem. You just need to have good sealing around the intake and exhaust hoses.

    So it creates positive pressure in the house?

  • source
  • parent
  • hideshow 6 child comments
  • [–] 1 point 4 months ago (5 children)

    The air that is brought in from outside via the intake hose is the same air that is heated and then ejected through the exhaust hose.

    In theory, it shouldn't cause a change in pressure.

    So there is a separate intake and output inside the house for the cold air?

  • source
  • parent
  • hideshow 4 child comments
  • [–] 1 point 4 months ago (3 children)

    Outside air. If you are using AC, the intake probably isn't cold. But: air in => heated up by the AC => sent out.

    2 hoses in the window that connect to the back of the AC unit.

    If it’s blowing cold air into the house, there has to be an equivalent volume of air leaving the house.

  • source

    Air from room is cooled and that same air is blown back into the room after being cooled.

    Air from outside is pulled into AC (does not go into room), gets the heat from the air in the room, then is blown out as exhaust.

    If you aren't sure, look for a diagram or in-depth explanation.

    Well yes, I meant preventing that hot air from circling back inside through the window, since these usually come with a kit to fit into the window, but aren't particularly airtight.

    Also I'm genuinely amazed at how fast that thing fills a bucket with water from the condensation, it's ridiculous. I live near the sea so 70%+ is normal, but seeing it was still surprising.

    I have mine in the living room and it pulls in air from the rest of the house, air filters in from many different places.

    As far as I know they are mosty designed for vertically sliding windows, uncommon in Europe. For american style sliding windows a think they are brilliant.

    That's not really a portable AC, or even a minisplit. I am talking about a portable AC with two parts (thus called a split unit), one for the outside that dumps the heat, and one on the inside blowing cool air. They are connected with flexible pipes.

    My dream car (that i could most realistically get) is the Mitsubishi Lancer Evolution Final Edition 2016. I love Mitsubishi's transmission and there's just something about how the Lancer Evo Final looks. I love rally and ideally i'd love the Mitsubishi Lancer WRC (or anything from the Group B Rally era lol)

    Forester XT SG ( STi if possible) would like a word. Actually the SF with the manual transmission and the high/low lever that worked in all speeds (effectively 8 speed manual, if you knew how to use it, with the most forgiving AWD) was a fucking blast. I owned one, and it was a blast. A soccer-mom-looking station wagon/early SUV that would humble BMWs daily.

    Splits are unreasonably expensive, and since there is now a compressor sitting somewhere outside and a bunch of piping, more stuff to maintain/go wrong. I remember buying my condo and seeing the split and thinking how convenient it is, but little did I realize after ten years the whole thing would need replacing. For what it cost, I could buy a new 5000 BTU unit every year and throw it out and break even after ten years.

    Here in the USA, south Mississippi, it's fucking hot as hell as well!

    And unfortunately, we're borrowing my mom's car for now, waiting for a part we ordered for the truck to come in. Mom's car has 4 windows, but only the front passenger window goes down, and no air conditioner.. 🥵

    I've taken to bringing a cooler with us, with bare minimum of 2 bottles of frozen fresh water, plus 2 bottles of frozen saturated saltwater.

    Why frozen salt water? Well it's definitely not for drinking, that's for sure. But frozen saltwater freezes at like -10⁰C, which makes them excellent ice packs to keep things in the cooler extra cold for around 6 hours or so...

    Stay cool out there everybody!

    I think the salt is actually worse for keeping thing cool longer.

    Most of the cooling capacity of the ice is in phase change from solid to liquid. The salt is moving it to -10 which means bigger gap from outside temperature. So the cold escapes quicker.

    If you use normal water it will climb to 0 faster, but stay there longer.

    I installed both AC and solar panels when heat got too dangerous for my kids.

    Yes, many everyday problems can be solved with money, money were literally invented for that exact purpose. Other problems can be solved with time, for example - trees need a fuckton of time to grow, but I still replaced most of the grass in my garden with trees and bushes. I will most likely never rest under their shade in my life, but is that really important to see the benefits fast?

    A man has made at least a start on discovering the meaning of human life when he plants shade trees under which he knows full well he will never sit.

    There's a ton of variants of this, and saying (in a form or another) apparently goes back to 1700s.

    That particular quote is from D. Elton Trueblood. Mark Twain said "The best time to plant a tree was 25 years ago. The second best time is now.". A bit different twist, but the same idea.

    There's also (alledeg) Indian proverb: “Blessed is he who plants trees under whose shade he will never sit.”. And many other variations of the same over the last 300 years or so.

    Unfortunately I bought a portable unit for my room. My reasoning, rooms gets to 38c and sleepless nights could mean sleeping through alarms, future health concerns and also, this heat won't be going down any time soon.

    Portable units are serviceable. Not nearly as good as split airco units but you can make them better by adding a second hose.

    The air inlet for cooling the compressor needs to draw air in from outside instead of from the room the unit is in.

    Portable units are absolute shit. For a little more you can buy a split like the OP's picture, that is an Air source heat pump, which is 3 to 4 times more economical to run than any other heat source. Plus they can run off solar panels, if the roof is yours.

  • source

    Thing is if you're renting you don't really have the freedom to install those units. And since AC is only really needed a few days per year it's good enough.

    I'd also much rather get the one from the OP but my options are limited.

    I have a portable AC for the main part of my house and a window unit in my bedroom. Where I live in the US it is literally a necessity. People without AC can get heat stroke and die in their own homes here in the hotter parts of the summer

    Central air conditioning, but designed better. It services individual rooms instead of taking the temperature of the entire house from one location and then distributing based on that.

    I consider these superior to central air due to its ability for zone control.

  • source

  • hideshow 1 child comment
  • [–] 1 point 4 months ago

    That would depend on just how many zones you want to control. If you have multiple rooms then you will need multiple mini splits. That adds up real fast. And multiple minis are more expensive to operate and maintain than one central HVAC system. Plus doors can be closed and duct vents can be adjusted easily.

    I'll have to get one at some point. It just seems a lot for the one week a year it's needed.

    Pretty spent this heatwave with a damp cloth wrapped around an ice pack and stuffed under my plums. Working from home is no fun when it's 35C in your room. I even stole the cat's cooling mat at one point (she hated it anyway) to use as a pillow.

    It's not just for cooling. It is very efficient at heating and warms up the whole room very quickly.

    In the winter we would wake up to a pre-warmed room. Didn't bother turning on the whole house central heating. The wife and I would get dressed in this room (and attached bathroom) and then quickly grab a hot drink and toast from the kitchen and leave the house, and then you save on heating the whole house in the morning. We would also turn off central heating really early in the evening. The house retains heat till we were ready to just chill in the bedroom, and then if it felt too chilly we could turn on the AC heating for a little while. My wife was using an electric fan heater every night despite central heating anyway and needed a blast of extra heating in the bedroom when she always felt particularly cold. Between getting this AC, buying my wife an electric blanket and changing to an electricity tariff that gives quarter price overnight (it costs almost nothing to run this overnight on hot nights).... A friend in a similar sized house has been amazed that our energy bills are one third of his (although we are particularly frugal with energy (15 min of water heating is all we need in 24 hours) and they are particularly bad with energy (overheating central heating and then opening their windows in winter!)).
