Hi,
I have an "EpykMod Pack" and i don`t know, how to refridgate food. I have created room, set there a cooler, and set temparature to, in the beginning -20, later -100 :p. But when i clicked potatoes, "they" said, that they aren`t refridgated.
You can see the room temperature on the right side of the screen when hovering your mouse over the room. If that is not going down at all, then you probably haven't set it up correctly, or maybe one cooler is not enough.
also make sure the blue side of cooler is facing the room you want to cool.
Shot that potato with spoonge gun its insta frost :D
Also make sure that the cooler is venting the hot side to an area labeled as outside. If you are venting into an inside room that gets too hot, the cooling will not work effectively.
