Abstract: A cabinet for the storage of goods requiring refrigeration, includes a modular frame structure, space-delimiting elements and shelves (6) bearing the goods, and equipped with a caloric heat exchanger (8) generating an air flow of a temperature selected to suit the goods, and an air channel system (17) communicating with it. Thus a refrigerated cabinet of any size and design can be transformed from an existing cabinet or a mass-manufactured cabinet product range, without altering the module structure of the non-refrigerated cabinet, incorporating all advantageous characteristics of a modular assembly option. The transformation implies no permanent change in structural design, basic parameters or external dimensions of the original cabinet, so it can be transformed back into a non-refrigerated cabinet at any time, by replacing certain elements and the installation and fitting of further units.
