Midea u shaped 8000 btu window AC variable capacity and power consumption testing and review

all right so just installed this my dia 8000 btu u-shaped inverter window air conditioner i have my uh kilowatt power meter on here been doing some testing today my dia does not give you very much information about the variable capacity and how it works and some of the things you can do in the app a lot of things i had to figure out on my own i reached out emailed them like a week ago sent several emails they never answered back so i guess their customer support isn't so great but um i've been able to come up with some of my own calculations and my own observations just learning a little on my own so this morning it was about i think 68 or 70 degrees out and the lowest wattage i could get this to run at was 100 around 160 watts after it had been on for a while so it could stabilize and the energy efficiency ratio or now they call it a c-e-r don't confuse that with seer with a s that's a little different that's a inflated exaggerated number anyways so if you multiply that 15 times 160 watts it gives you around 2400 btus well now it's a little warmer outside it's around 80 degrees and the lowest i can get it to run is about 190 watts which is about 2800 btus so it varies as vtu's not only depending on where you set the room temperature compared to uh the current temperature that it already is in the room but also depending on the outside temperature and what i noticed is it seems to actually read its own outdoor temperature it must have a sensor somewhere because i would i checked with three weather stations in town and this was reading like one or two degrees lower and then when the unit shut off it actually read two degrees warmer so it might not be 100 accurate when the unit is on it might be feeling some cold air somewhere i'm not sure maybe it's feeling some of the cold water drips off the coils and then goes down into the pan so maybe it could be reading some of that cold water in the pan somewhere even though i'm sure the temperature sensor is outside probably but the fact that it would even read one or two degrees cooler makes sense because we're up on the mountain which usually is one or two degrees colder than it is in town so that sounds about accurate i have yet to see what temperature it reads when the sun hits the unit directly that would probably warm it up a little bit but now here's the highest that i've seen it run this morning um i think when i turn it down all the way to 60 the highest wattage i can get it to hit if i remember correctly i think it was like 360 watts or something like that which equaled out to like 56 or 5800 btus something like that it wasn't anywhere near its full capacity but now that's 80 degrees outside i cranked it all the way down to 60 a little while ago and um i forgot exactly how many watts a 535 yeah it was staying between like 530 and 540 average about 535 watts which came out to right about 8 000 btus or just a little over so when it's hotter outside it can hit full capacity which i think that's fantastic um it's really quiet you'll notice right now it's super quiet it's on its lowest speed when you put it on auto i've noticed it actually has like it seems to have about two speeds lower than low it just won't display it if you use the app you can even customize the fan speed anywhere from like 10 to 100 percent but i've just noticed like right now if i drop it down one degree it'll go up to the next speed if i drop it down 68 it'll go up to low 67 medium 66 high so it kind of seems to have about five pre-built in fan speeds when it's on the auto mode and it depends on how cold you set it versus how cold it currently is in the room and each time it drops a fan speed it'll also significantly significantly change the amount of wattage it's pulling because every time you change a fan speed it's not like other window air conditioners where you're just increasing the fan speed up or down slightly like 10 percent no this instead the maximum fan speed is like 476 cfms and the lowest is probably like 48 cfms which is like 90 lower right so every time you change a fan speed it it changes the speed on the compressor also and changes its capacity it's very different from other window air conditioners that's great if you're in a room that like this is going to be a game room with computer stuff so sometimes when all the gaming stuff's on it's going to produce more heat and then when no one's in here there's not going to be that much heat in the room so variable capacity is really great for things like that it's also usually good for moisture control when you have variable capacity but that's one flaw i've already noticed on this window air conditioner even with the eco mode on when the compressor shuts off the fan stays on for a little while which throws moisture back into the room off of the evaporator coils so that is one thing that really bothers me the other thing that's really an issue to me is i've noticed all day long on average this unit stays about two to three degrees lower than what you set it for and it won't even shut off until it's four degrees colder than what you set it for and then it won't turn on until it's exactly what you set it for so what you end up with is this whole four degree range and fluctuation of temperature instead of staying where you set it i'd like an air conditioner to stay within one degree of where i set it four degree fluctuation that means you're gonna constantly be hot cold hot cold hot cold and that's just no fun for anyone so uh yeah i i mean i don't know if that doesn't bother you go ahead and get it but for most people i think and for me personally uh i actually wouldn't recommend it if you like constant temperature so that is one big thing that really uh i was kind of surprised by but i've also noticed that with uh friedrich or frederick however you say air conditioners they have that same problem huge fluctuation in temperatures then i've noticed uh i've been keeping an eye on the humidity though and uh the variable capacity does seem to help somewhat because even though the fan stays on when the uh compressor is off i've noticed the humidity in the room hasn't really gone up or down all day whereas if you use like a friedrich air conditioner or frigidaire they're so bad the moisture will actually increase while the unit is on which defeats the whole purpose of an air conditioner but still the best air conditioners are lg you'll see the humidity levels drop with those lg units the lg units they keep a constant temperature depending what model you get some are quiet some aren't but they're reliable they last a long time i really never find anything to complain about with an lg unit unless i happen to get one of the models that's kind of loud but other than that lg still is the king of air conditioners oh and they do out actually also now make inverter units so i just wish they would make more sizes because i think they only have like a btu and then a 14 and a 22 or something like that the nice thing about my d is having the 8 10 and 12 but i mean i'm still not that impressed overall um oh okay so the app i almost forgot to talk about the app that was a pain to get connected and to figure out also the installation instructions were terrible on this so installing it took a couple hours it took longer than any window air conditioner i've ever done it does seal better i will say that but the instructions were terrible the instructions on how to do the app are terrible i finally figured it out after a while that was a pain and the really cool thing about the app though is you can use it like a programmable thermostat you can set different temperatures at different times of the day you can set a sleeping curve so over eight hours you can choose what temperatures you want either going up or down over eight hours you can customize it whatever times and temperatures you want while you sleep or you can just use the other timers like i said before it's nice that you can also turn the display on and off but a friedrich air conditioner also do that and you can make the air swing but personally i just like it pointed up and i really wish it would point up higher it doesn't the air i can feel it here see i wish it would go like straight up towards it maybe i should go like this so you can see better see it shoots off a little bit of an angle like that but personally i like to be able to shoot straight up at the ceiling and then let the ceiling fan blow the air back down i like shooting cold air up because that's where all your hot air is that way it helps move the hot air out of the room whereas if you have cold air going across here and then your cold air is getting sucked right back in right there at that you know it's it's just not as efficient that way so anyways that's uh things that i've noticed observed tested my thoughts all that good stuff on this new ac
