This part of the heat load is often referred to as door-to-door cooling consumption or door-to-door cooling loss. When the door of the cold storage is opened, the amount of hot air entering the cold storage is related to the height and width of the door, the temperature difference between the inside and outside of the storage, and of course the time and frequency of opening the doo…
