FIELD: heating system.
SUBSTANCE: cooling system includes a cooling cycle having: a circulation circuit (101) in which the refrigerant flows; And at least one compressor (102) for compressing the refrigerant, a heat exchanger (103) for cooling the refrigerant compressed by the compressor, at least one turboexpander (104) for expanding the refrigerant cooled by a heat exchanger to generate cold from heat, and a cooling element (105) for cooling an object to be cooled by heat from the cold, which are provided in series on the circulation circuit, where at least any of at least one compressor or at least one turbo expander is included into a plurality of compressors or turbines, which are arranged parallel to each other with respect to the circulation circuit.
EFFECT: increasing the efficiency of mounting in a confined space, good reliability.
