Abstract

A cooling system including a compressor (10) compressing a refrigerant and a condenser (60) condensing the compressed refrigerant, includes: an evaporator section (51, 52) having a plurality of evaporators (51, 52) evaporating the refrigerant condensed in the condenser (60); a switching valve (30) on a refrigerant line between the condenser (60) and the evaporator, and selectively switching a refrigerant supply to the plurality of evaporators (51, 52); and a refrigerant expansion part (41, 42) adjacent to at least one of the evaporators, allowing refrigerant introduced into the plurality of evaporators (51, 52) through the switching valve (30) to expand. A refrigerant inlet of the refrigerant expansion part (41, 42) adjacent to any of the evaporators is connected to the switching valve (30), and a refrigerant outlet thereof is connected to an inlet of another evaporator.
