Passive cooler
A traditional unpowered cooler that works by water evaporation. Must be regularly replenished with wood. Not efficient enough to refrigerate food.

The passive cooler is a low-tech alternative to the cooler. It does not require power or any advanced materials, but requires wood to refuel.
Acquisition
Constructing a passive cooler requires Passive Cooler to be researched, which both New Tribe and New Arrivals start with. It requires 50 Wood and is constructed in 200 ticks (3.33 secs).
Summary
Passive coolers absorb heat from interior spaces at a rate of 11 °C (19.8 °F) per second, spread among each tile. They cannot lower the temperature below 17 °C (62.6 °F). In order to do so, passive coolers consume 10 wood per day; they must be restocked at a cooler's full cost every 5 days.
Analysis
Passive coolers are unable to preserve food, but they can protect your colonists from heatstroke and prevent debuffs such as "Slept in the heat". Unlike campfires, passive coolers can't be "too efficient" and make your pawns uncomfortably cold.
They are very fuel inefficient, even compared to running coolers on wood-fired generators. However, they have the great advantage of not needing electrical power to function. As such, they will save your fermenting barrels from going bad during a solar flare.
