Refrigeration units are vital to the food and beverage industry to ensure proper storage temperatures and to maintain health and safety regulations. Refrigeration and cooling methods continually advance to simplify beverage transportation and beverage dispensing. From small consumer appliances used to refrigerate milk, coffee, beer, juice, soda and wine, to large mobile carts that transport food from a kitchen to a catering point, refrigeration ensures beverages are consumed at appropriate safe temperatures. Refrigeration units utilizing thermoelectric modules (TEMs) are an alternative to conventional compressor-based systems for beverage cooling. Because a thermoelectric assembly (TEA) is compact, robust, and completely solid-state, the inherent reliability of such a system is attractive to engineers and end-users alike.
