Cooling is kind useless for most of the game in Palworld. Cheap food is made in bulk so rot in pieces so you won't mind 1 of your 1000 berries going bad and cakes can be stored in a spare breeding pen so it does not rot or just use the Guild Chest which somehow put the food in stasis. 

I feel Pocket Pair created the cooling mechanic so food rot was to be an important part of the game, found it to be too annoying and just made is kind not necessary and thanks Panthalus for that.
