Abstract

A refrigeration system may include a compressor configured to compress a non-azeotropic mixed refrigerant; a condenser configured to condense the compressed non-azeotropic mixed refrigerant; a three-way valve configured to branch the non-azeotropic mixed refrigerant condensed by the condenser; a first evaporator configured to supply cold air to the first internal space; a second evaporator configured to supply cold air to the second internal space at a temperature higher than a temperature of the first internal space; and a capillary tube configured to expand the non-azeotropic mixed refrigerant branched by the three-way valve, and supply the expanded non-azeotropic mixed refrigerant to at least one of the first evaporator or the second evaporator. By utilizing the characteristics, an efficient refrigeration system using the non-azeotropic mixed refrigerant can be realized.

Description

technical field [0001] This paper discloses a refrigeration system using a non-azeotropic mixed refrigerant. Background technique [0002] A refrigeration system is a system that provides cold air. In a refrigeration system, a refrigerant cycles through a process of compression, condensation, expansion, and evaporation. [0003] There are various types of refrigerants. A mixed refrigerant is a refrigerant in which two or more types of refrigerants are mixed. Mixed refrigerants include azeotropic mixed refrigerants and non-azeotropic mixed refrigerants. [0004] Like a single refrigerant, an azeotropic mixture refrigerant is a refrigerant that undergoes a phase change without changing the composition of the gaseous and liquid phases. The evaporation temperature of the azeotropic mixture refrigerant is constant between the inlet and outlet of the evaporator. [0005] In a non-azeotropic mixed refrigerant, the refrigerant with a low boiling point evaporates first, and the ...
