Abstract

Official abstract text for this publication.

A cooling system includes a compressor configured to pressurize carbon dioxide to form pressurized carbon dioxide, a mixer configured to generate mixed refrigerant in which the pressurized carbon dioxide and solvent in a liquid state, a depressurization apparatus provided downstream from the mixer and configured to depressurize the mixed refrigerant, a separator configured to separate carbon dioxide in a gas state from the mixed refrigerant, a heat exchanger configured to exchange heat between the mixed refrigerant cooled through depressurization and a fluid to be cooled, and a second heat exchanger configured to cool the carbon dioxide or the mixed refrigerant using vaporized carbon dioxide or the mixed refrigerant.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cooling system comprising: a compressor configured to pressurize carbon dioxide to form pressurized carbon dioxide; a depressurization apparatus configured to depressurize the pressurized carbon dioxide, the depressurization apparatus including a valve; a mixer provided downstream from the depressurization apparatus and configured to generate a mixed refrigerant in which the pressurized carbon dioxide, which is depressurized, and a solvent in a liquid state are mixed; a separator provided downstream from the mixer and configured to separate carbon dioxide in a gas state from the mixed refrigerant; a second depressurization apparatus configured to depressurize the mixed refrigerant, the second depressurization apparatus including a valve and being provided downstream from the separator; a heat exchanger configured to exchange heat between the mixed refrigerant cooled in the second depressurization apparatus through depressurization and a fluid to be cooled; and a second heat exchanger configured to cool the mixed refrigerant in a first mixed refrigerant flow path using the mixed refrigerant cooled in the second depressurization apparatus through depressurization and in a second mixed refrigerant flow path, the second heat exchanger being integrated with the heat exchanger.
