AI Technical Summary

Technical Problem

Existing refrigerators with cold storage materials face inefficiencies due to a time lag between evaporator cooling and regenerative material cooling, leading to delayed cold storage and reduced effectiveness during demand response scenarios.

Method used

Thermally contacting the evaporator with the cold storage material and maintaining the evaporator temperature below the solidification temperature of the cold storage material to enhance cooling efficiency and rapid cold storage.

Benefits of technology

Improves cold storage efficiency by shortening the time required for cold storage and release operations, enabling rapid response to demand signals and reducing energy consumption.

Abstract

To provide a refrigerator that comprises a cold storage material, and more quickly stores cold during cold storage operation.SOLUTION: A refrigerator according to the present disclosure comprises: a cooling system in which a compressor, a condenser, pressure reduction means, and an evaporator are connected in a circular pattern; a storage chamber internally comprising the evaporator; a cooling fan for circulating cold air generated by the evaporator, in the storage chamber; a cold storage material in thermal contact with the evaporator; and temperature detection means for detecting the temperature of the evaporator; and controls the temperature of the evaporator detected by the temperature detection means so that it becomes equal to or lower than the solidification temperature of the cold storage material.SELECTED DRAWING: Figure 1
