RimWorld Science: Coolers and Freezers — RimWorld Alpha 16 Freezer SCIENCE!!!

hey welcome back to rim world science now last time we looked at thermodynamics the way that heat transfers between walls and we learned a few things there and people were asking for a bit more information about how this applies for instance to freezers and coolers and that is we're to look at in more depth today now it's a quick recap one thing to be learned is because of the way that temperature kind of moves through walls the best freezers are going to be square they're going to have double walls and they're going to be underground because he can't get through the roof but now we want to look at some more detail and we're going to start by looking at how coolers themselves work how the air conditioning units work now the first thing to note is that as you see right here it doesn't matter where in your room you put the coolers you got three different rooms here where the coolers are all in different kinds of places here they're all kind of bunched up here they're across they look kind of in there and I have them all set to the maximum you know so they're always always running at full power and if you look - 27 - 28 - 28 and as we kind of go over now - 26 26 27 so they fluctuate a little bit but they're all well within just a degree of each other this also applies to vent so here we have two rooms with cooler in each of them they're both down between 4 & 5 degrees Celsius same dealer said - all the way down but one of them is real close to this vent and one of them is real far away but in both cases the vents the vented rooms are exactly the same at 7 degrees but although the cooler position doesn't matter something else does every cooler will vent that's the little red side you see poking out and it'll push heat to the outside of the vent now if it's like this where it goes to the outdoors nothing we can do will change the outdoor temperature on its own but if it goes into a room like it does right here if this room gets too hot then it can't get enough kind of cooling power and you see these rooms are all that - you know 28:29 this one is 17 because got two coolers all the way down it gets so hot there behind them it just can't keep up now notice one thing we might try to just destroy the roof over these but unfortunately it's still going to stay really hot in here because these little tiny rooms of size one are just bugged they don't cool down even when they're unroofed please expect them to so instead if you come and destroy this wall now these go all the way to the outdoors so if we give us a little bit of time this is going to yeah quickly get down to around the kind of temperatures these ones are at as well now the next thing we want to do is look to see exactly how much cooling power you can get out of each cooler since we know that square double walls of cooler cooler rooms are the best I'll just test those that means that we're only having rooms where the number is a square and we go from here all the way up to this most one by one room here all the way up to this eighteen by eighteen room here the biggest we can make it without having a hole in the ceiling and what I've got here is in each one of these rooms I've got a cooler that's set down to hook 270 degrees and so what we'll do is we'll run run this for 24 hours and then we'll do another one on a cold snap and another one on yoga heatwave and see how each of them do okay so you can see the result here at 31 degrees 48 degrees and four degrees and it's not obviously like any patterns of looking at it but if you look instead at this graph you can see it's a pretty like straightforward arc each time where there's just kind of a dip for you know between the hottest the middle and the cold that's about the same as the dip in the temperatures and I think that is approximately right it's not exactly perfect because some of the way that the rooms would heat up more aggressively depending on how you know how many the differences makes a little bit of a difference but basically you can think of each cooler as just having like a set amount it will number of degrees it will lower the room for that room size so for instance a single cooler in a size 1 room will lower the temperature by about 110 degrees and a size 2 size for room square about 96 97 degrees and look it lowered and so on and so forth now the next question of course is to ask how adding more coolers to a room works just double the amount that goes down so we'll try this with two coolers three coolers and four coolers is the same thing just set them all down to minus 270 run them for 24 hours and see how they look the next day now what I've done here is simply a chart out the how much cooler the room is for each of these than how much the outdoors is because when I tested the outdoors might have be a different temperature so the absolute values this is the difference we're looking at now as you can see as we went from one cooler to two coolers to three to four the amount of like extra cooling powers that we got kept kind of dropping is you also see like the closer the smaller the room was the more those extra coolers didn't do any good in fact actually the smallest ones having nicer coolers actually made it worth advance because every cooler that you add is one fewer double-wall and at a very small room the value of a tional cooler is just swamped by like having or quartering the number of double walls that you have so now we have a kind of idea about how the coolers work we might want to ask ourselves are we that like game or otherwise abusive system now the first thing you might think is because as the room gets bigger the kind of number of degrees that a cooler can push down goes lower maybe we do better by having some small freezers with instead of one big freezer like maybe say maybe three coolers across three different freezers would do better than three coolers in one freezer but it turns out that doesn't work so well so here I have one this is a seven by seven room so this is 49 squares this is three four by fours so it's 48 they're really close in size and I've got you know three cooler it's all set to minus 270 running on this one room versus three here each in a separate room and it turns out this isn't - 45 and these are actually you'll -41 minus 40 sit you know come they're bouncing around a bit 43 just right about the same these ones also - 43 2 - 45 so we do you know this is actually slightly cooler than this so there are sort of things you might try to to exploit the fact that coolers can cool a small room down a lot more aggressively than a big room so an earlier Alfa's there was this trick right here where you could put a cooler feed it into just a one by one room and then vent it to a bigger room and you get a lot more cooling power than just putting the cooler straight in but that's been fixed or broken if depending on your point of view in alpha 16 so here we've got you know these three all set to minus 270 going into a single room with a free airlock freezer here we've got three just kind of going straight in this is like at minus 10 minus 11 this is only at 1 degree this is much much colder now you might also wonder if you a similar trick like here of three of these cooling a much smaller room and inventing it into a bigger one but again it's not doing nearly as well this again is minus eleven this here is minus six and this is at minus three now another thing we might try relies on some of the weird behavior that we pointed out last time about how double walls that are indoors it treats what's on the other side as though it was outside and so sometimes if you're have a cooler thing on the other side of your freezer it looks like it might be more sensible to have a single wall between that into the double wall which will go to the outside so the kind of test is saw I've got these two different setups here we've got some coolers that are each just set to 21 degrees and the idea is these would be like the bedrooms or something that these are feeding into and then three coolers into a big room that is like a cooler and it's double walled here same sizes here but here it's only single walled where it borders with the you know the so called bedrooms and we've double walled the outside to see how it goes and now if we look at this this is it - twelve and this is at minus 11 so this one is actually a little bit cooler we're not actually getting more cooling power by having a single walls over here but there is something kind of strange you'll notice is here these 21 degree coolers they are running hot they are running really high to keep these bedrooms at 22 degrees these ones here they're not running at all and they're keeping this at 16 degrees and that suggests a kind of trick like this one so here we've got another freezer same size as this one but it's surrounded by these rooms that all vent into each other another you know three feeding in just like it was over here over here we've got it minus 10 over here it's also at minus 10 and if we let it go for a little bit sometimes this will get slightly warmer but they say really really close but notice all of these rooms are not cooled at all but they're all set at 10 degrees Celsius so the cooling in here is like leaking into these rooms that keeping them cool while not really losing anything here whereas here it's is leaking outside and they're not gonna benefit from it so although we can't make our freezers more efficient if we're looking a really hot biome well to keep our bedrooms nice and cool or our work rooms a design like this where we use comes the ambient coolness of the freezer to leak into the rooms outside can be very efficient so unfortunately all that's mostly negative is not a lot of ways to game the system or use these which we've got to improve our freezers beyond it's making them square although we can use that ambient coolness to help other rooms bordering our freezer now let's finish up by looking at airlocks so it's often explained that if you've got a nice cool room and here's one but these are all at minus 270 in order to keep it cool when you have people going in and out you want to have this kind of double door air lock setup now some things I've been wondering for a while one is just how much coolness do you actually get so here's a single door here's a double door how much am I going to say that these guys are going back and forth second question so we know that heat doesn't hit through corners do we need to have corners here on the doors or not or is that going to be different and finally what kind of doors do we need so here I've got these are all wood I've got wood steel and sandstone and here I've got auto doors wood steel and sandstone now all don't doors the same speed now all of these people here are the exact same walking speed of 4.5 eight cells per second and what I'm going to do is I'm going to have each of these guys go in and out 10 times each of these are just set to minus 270 there's no coolers so we'll just see like which one takes on the Moche and which one stays the coolest to see which of these setup is most efficient okay that's ten runs let's see how this did I start with the top row of wooden doors - 113 for our kind of control - 103 for the single door - 109 it will be cooler for the double door which still got a lip here and 108 one degree warmer over ten back-and-forth here so it looks like having these lips does make a little tiny bit of difference but not huge but it's make a difference now for different door types we have - 109 here for the wood door - 109 here for the steel door - 108 again it's a 1 degree difference but a little bit warmer here for the sandstone doors and that actually makes sense because the opening and closing speed of the sandstone door is considerably slower in fact without let these guys have a race and you can just see it in action here see ya she's already there and so these doors spend a little bit more time open and so there's a little bit more heat loss or you know heat sneaking in during that now hop it over here we've got minus 94 here a minus 94 for the wooden and the steel auto doors but minus 97 so a little bit actually cooler here for the for the Samsung Auto door and notice that's even a little bit cooler than these ones over here things went up because of the few minutes you know when they're moving that was heat sneaking in from the sides - so that seems surprising is that these are actually reversed that the sands auto door is actually the best of all the different types of doors but we can actually see why again if we watch these guys in action here so notice that is so fast that for a moment they're both doors are open at the same time and that means that you know heat can be coming in really fast through both doors whereas these are a little slower and so like this one they won't have a book open the same time like that so surprisingly it turns out that stone auto doors are the most effective type of doors to use for your air locks but that's going to be it for rim world science today unfortunately a lot of what we learned was negative we learned that it's much harder to kind of game the system using what we've learned about how thermodynamics works in rimworld than we saw although we can use the coolness of a freezer to cool up rooms around it by putting single walls between it and we also learned here it'll comes to air locks that stone auto doors are the most efficient thing to do so when you build your freezers make them square put them underground put some rooms around it that you want to keep cold and then double wall the whole complex and use these stone auto doors for the most efficient freezers that you can unfortunately it looks like if your freezer so big you're having a hard time keeping a cold there's going to be no substitute for just building more coolers let me know if we've missed some trick that we should have looked at and let me know what else we should do science on in rimworld until then thank you so much for watching and I'll see you soon
