A freezing room, also known as a cold room, is a temperature-controlled room used for the storage of perishable goods and other temperature-sensitive products. It is designed to maintain a specific temperature range, usually between -18°C to 10°C (0°F to 50°F), depending on the type of product being stored. Freezing rooms are commonly used in the food industry for the storage of fresh or frozen food products, such as meat, fish, poultry, fruits, and vegetables. They are also used in the pharmaceutical industry for the storage of vaccines, drugs, and other medical supplies that require a controlled temperature environment. The design and construction of a freezing room are crucial in maintaining the desired temperature range. The room must be insulated to prevent heat transfer from the outside environment, and the refrigeration system must be able to maintain the temperature range consistently. The refrigeration system can use various types of cooling technologies, such as air cooling
