A closed room that is intentionally cooled to a temperature of just above freezing is also referred to as a cold room. Cooling usually occurs electrically or by means of gas. Slowing down chemical reactions and the growth of micro-organisms is the objective of a cold room. Rotting or ripening is unwanted.
Cold rooms are usually used by companies that work with perishable goods, such as the food industry, catering industry and hospitals with laboratories. Additionally, there are large cold storages, that consist of multiple cold rooms for various products and/or customers.
Depending on the product, a cold room is built that is cooled in a controlled way. For example, the storage of apples requires a different kind of cooling than meat.
