We abuse that fact, and the fact that coolers can be used as walls to form a "Chimney" of sorts. And an outdoors room normalizes its temperature with the outdoor temperature. In RimWorld, if a room is less than 75% roofed, it's considered outdoors. A way to protect the coolers would be nice, but how can we vent the hot air if we also have to protect the coolers? So, what's the problem? The problem is the fact that Coolers have really bad HP, and raiders love to destroy them on sight. Making triple/quadruple thick walls won't improve insulation in the slightest. Remember, double thick walls are the limit. With a temperature of -29C, this design achieves a 79C reduction! Giving you considerable amount of time to prepare for a solar flare even during a heat wave. Obviously, if you manage to build double thick walls under overhead mountain tiles, that outperforms both of them by a significant margin. Without that, both doors will be opened at the same point. The one tile gap between them is important. The airlock ensures that minimal amount of outdoors air comes into contact with the indoors air when the doors are opened. In RimWorld, when you open a door, the game tries to normalize the temperature of the rooms it's connected to. If you are wondering, why do I have the doors lined up that way, it's because they form an airlock. 6C means a 56C reduction, which is almost equivalent to single thick wall with overhead mountain tiles! What other options do we have?ĭouble thick walls! Double thick walls improve insulation. Overhead mountain tiles are amazing, but it's not always feasible to build your freezer under them. A lower temperature means you'll have more time before the freezer heats up in case of a Solar Flare. A higher temperature would result in the coolers getting to the low power state quickly, saving you power. The temperature the coolers are set to, does not affect the minimum reachable temperature for a freezer, but it does affect the efficiency.Contents of the freezer does not matter, unless it's something that actively heats up the room.Wood has the same level of insulation as Plasteel. While I have built all the structures with Slate, the used material does not matter in the slightest.The room interior size is 9x9 in all tests. All the tests have been done in Extreme Desert + Heat Wave.All the tests have been done in Vanilla RimWorld + All 3 DLCs.A few things to keep in mind before we begin.
