Benefits of technology

The patent proposes a refrigeration system that prevents the temperature of the condenser from being lowered, increases cooling efficiency, and maintains constant temperature in the refrigerator by using a phase change material (PCM) as the cold storage material in the heat exchanger. The system does not require any additional expander, making the internal design of the refrigerator simple and maximizing space usage. Additionally, the system has a simple cycle structure, reducing manufacturing costs.

Problems solved by technology

However, in a conventional refrigeration system, a subsidiary condenser may be provided so that a plurality of condensing processes are performed in the refrigeration cycle in some cases, but, in this case, there is a problem in that a radiant value of a main condenser is lowered due to the subsidiary condenser, and thus cooling efficiency is reduced.

Abstract

Disclosed are a refrigerator and a control method thereof. The refrigerator according to one aspect includes a main body having a storage chamber; a compressor configured to compress a refrigerant; a condenser configured to condense the refrigerant compressed by the compressor; an evaporation expander configured to depressurize the refrigerant condensed by the condenser; a first evaporator configured to evaporate the refrigerant depressurized by the evaporation expander and thus to cool the storage chamber; a condensing expander installed between the condenser and the evaporation expander and configured to depressurize the refrigerant condensed by the condenser; and a subsidiary condenser installed between the condensing expander and the evaporation expander and configured to condense the refrigerant depressurized by the condensing expander.
