Abstract
A refrigerating device including a hollow-walled housing surrounding a first and a second storage compartment. A vacuum pump is controllably connected via a suction line to the hollow chamber of the housing and to one of the storage compartments. The pump is controlled to maintain a desired pressure range in both the housing and the storage compartment.
Claims23
