Cold Rooms 2

[afa13]

When designing a cold room should you introduce ventilation or not and if so should it be a positive pressure or a negative one?

P.S: the cold room is used for food storage (meat, fruits, canned food, etc...)

I have seen several cold rooms (never designed one though) and none had ventilation air. Ventilation is for people usually. I would think it would make a lot of frost on the coils. With no occupancy, why provide ventilation?

Ventilation is usually only required in cold rooms that have some sort of oxygen depleting activity or some type of hazardous material storage (people working / plant growth etc and some other specialty applications). Food storage coolers and freezers almost never need ventilation. The associated refrigeration load can be pretty big from a small amount of ventilation.
