A refrigerator (16) for rapidly cooling down and then maintaining a plurality of wine bottles (18) of arbitrary configuration within a selected temperature range comprises a compression type refrigeration unit (14) in association with the refrigerated compartment (16) which receives the wine bottles (12). The refrigeration unit (14) includes a controllable expansion valve (32) and a control system (20) in which a microcontroller (22) is arranged with a plurality of stored cooldown models as references for bringing the wine bottles to temperature without damage to the wine. Temperature (62), pressure (52) and air flow (58) measurements are used by a computer (22) programmed to determine the status of the thermal loads as affected by the number of wine bottles (18) and their temperatures, and to adjust variations in the load compartment temperature for both cooldown modes and steady state mode. Given an arbitrary thermal load, the refrigerator system (14) lowers the wine temperature in a maximized but controlled manner so that chilled wine is available in no more than 30 minutes.
