REFRIGERATORS; COLD ROOMS; ICE-BOXES; COOLING OR FREEZING APPARATUS NOT OTHERWISE PROVIDED FOR (refrigerated showcases A47F3/04; thermally-insulated vessels for domestic use A47J41/00; refrigerated vehicles, see the appropriate subclasses of classes B60 - B64; containers with thermal insulation in general B65D81/38; heat-transfer, heat-exchange or heat-storage materials, e.g. refrigerants, or materials for the production of heat or cold by chemical reactions other than by combustion C09K5/00; thermally-insulated vessels for liquefied or solidified gases F17C; air-conditioning or air-humidification F24F; refrigeration machines, plants, or systems F25B; cooling of instruments or comparable apparatus without refrigeration G12B)

Description

F25D encompasses refrigerated storage equipment and structures for maintaining low temperatures in commercial and domestic applications. This subclass covers refrigerators, freezers, cold storage rooms, ice-boxes, and general-purpose cooling or freezing apparatus that do not fall under more specialized refrigeration classifications. The classification includes insulated cabinets, walk-in cold rooms, defrosting systems, and internal components such as shelving and temperature controls specific to storage vessels. F25D excludes refrigeration cycles and compressor systems (covered under F25B) and industrial ice manufacture (covered under F25C).
