FREEZER, AND REFRIGERATOR PROVIDED WITH FREEZER

Title:

FREEZER, AND REFRIGERATOR PROVIDED WITH FREEZER

Document Type and Number:

WIPO Patent Application WO/2002/039036

Kind Code:

A1

Abstract:

The respective evaporators have proper evaporation temperatures to improve the freezing cycle efficiency, resulting in the reduction of energy consumption. The freezer and refrigerator are provided with a compressor, a condenser, a plurality of series-connected evaporators, a refrigerant flow rate changing device, and a refrigerant, these forming a refrigerating cycle. The refrigerant flow rate changing device controls respective evaporation temperatures for the plurality of evaporators. Desirably, the freezer further includes a bypass circuit which bypasses at least one evaporator, and the refrigerant passes through the bypass circuit as needed. The refrigerant flow rate changing device controls the flow rate of the refrigerant such that the evaporation temperatures for the evaporators positioned on the upstream side of the refrigerating cycle are higher than those for the evaporators positioned on the downstream side.
