Pointing the cooler's hot side outdoors would be the simplest way to do so.Īlternatively, you can point the hot side to a "chimney", an unroofed, 1x1 or so room.

Without a way to exhaust the heat, it will leak back to the cooler room, making it hard to actually cool. Regardless, the hot side must be accounted for. You could also point the hot side at a greenhouse, supplementing heaters during the cool-but-not-freezing season. This isn't recommended if the outdoors temperature often goes above 20 ☌ (68 ☏) otherwise, the cooler will make your colony unbearably hot when you actually need the freezing. It could be used for heating a base when the outdoors temperature is uncomfortably cold, but not freezing - specifically, between 1 ☌ – 16 ☌ (33.8 ☏ – 60.8 ☏). Having a bedroom above 26 ☌ (78.8 ☏) gives colonists the Slept in the heat negative moodlet apparel does not alter this fact.Ī small, unroofed area to let the heat out. Too far beyond a pawn's Maximum Comfortable Temperature will make them vulnerable to heat stroke and gives the Hot negative moodlet. You may want to set a cooler a few degrees below 0 ☌ (32 ☏) to keep a slight buffer against temperature gains from opening doors, cooler breakdowns, power outages, etc.ĭuring a heat wave, or inside harsh biomes, like a Desert, coolers are useful to regulate pawn temperature. If using autodoors, make sure to leave enough space between each one. You can create an "airlock" with multiple doors as one door is opened, the next closes, which keeps heat out. Heat leaks in more when pawns open doors. If a room is colder than its surroundings, then heat will leak inside.

In many warmer biomes, spoilage is a major obstacle in maintaining a food supply, and thus freezer construction is generally considered a high priority. Cold temperatures will slow down spoiling, until the freezing point, a temperature of 0 ☌ (32 ☏), which prevents spoilage completely. Perishable items will spoil if not kept cool. Under these conditions, 2-3 coolers were required to maintain a constant (frozen) -1 ☌ – 0 ☌ (30.2 ☏ – 32 ☏) within the same space.Ĭoolers are often required to create freezers.

Simple playtesting reveals that with an exterior temperature of 27 ☌ – 38 ☌ (80.6 ☏ – 100.4 ☏), a single cooler can cool a room with a 10x10 exterior to a minimum temperature of 10 ☌ – 16 ☌ (50 ☏ – 60.8 ☏). If you have multiple coolers in a room, you can exploit this by having each cooler be 1 degree lower than the last - one will actively cool the room, while the others will be in low power state.Ĭoolers can theoretically cool 1800 degrees Celsius, total - 1 tile by 1800 degrees, 50 tiles by 36 degrees - but this is before considering outside temperature. If the room's surroundings are warmer, then the room constantly needs cooling, and a cooler remains at high power. If the target temperature is reached, a cooler consumes 20 W (low power).A cooler that is actively cooling consumes 200W (high power).See the temperature page for more details.Ĭoolers have two states of power consumption: high and low. Coolers will attempt to cool the room to its target temperature, though surrounding heat and the room's size may make this impossible. The cooler must not be blocked on either side, and rooms must be enclosed with a mostly complete roof in order to actually be cooled/heated. If powered, they will cool their front side (shown by a blue tile on placement), and conversely, will heat their back side (red tile). It requires 90 Steel, 3 Components and is constructed in 1,600 ticks ( 26.67 secs).Ĭoolers take the place of a wall tile. Constructing a cooler requires Air Conditioning to be researched, which New Arrivals start with.
