Storage refrigeration refers to the process and systems used to maintain low temperatures for the preservation of perishable goods. This typically involves specialized equipment designed to remove heat from an enclosed space, thereby slowing down the metabolic processes of food and other sensitive materials, which inhibits the growth of microorganisms and enzymatic degradation.

The primary function of storage refrigeration is to extend the shelf life of products such as fruits, vegetables, meats, dairy, and pharmaceuticals. By keeping these items at temperatures below their spoilage point, their quality, nutritional value, and safety are maintained for longer periods. Different types of goods require specific temperature ranges to achieve optimal preservation. For instance, frozen storage is used for long-term preservation, while chilled storage is suitable for shorter durations.

Key components of a storage refrigeration system include a compressor, condenser, expansion valve, and evaporator. The compressor circulates refrigerant, which absorbs heat from the storage area via the evaporator and releases it to the outside through the condenser. Insulation of the storage space is crucial to minimize heat gain from the environment, thus reducing the energy consumption of the refrigeration system. Proper management of humidity within the storage area is also important, as it affects the rate of moisture loss from stored products. Different types of storage refrigeration exist, from small commercial units to large industrial cold rooms and warehouses.
