Why Does Ice Build up in Cold Stores and Freezers?

Why Does Ice Build up in Cold Stores and Freezers?

Ice build up is caused when moist air enters the cold store. Sometimes there can be thin layers of ice which has the appearance of snow. When the moist air comes in to contact with cold surfaces such as floors, walls and evaporator coils, the water vapour in the air condenses to form water and then freezes to form ice.

Moisture typically enters the cold store or freezer during door opening times.
