Engine component test system with cryogenic cooling system

A method for testing a component of an engine, comprising:

• directing compressed air into an air passage of a cryogenic heat exchanger;
• cooling the cryogenic heat exchanger with a quantity of dry ice;
• directing a cryogenic liquid into a cryogenic liquid passage of the cryogenic heat exchanger;
• transferring heat energy from the compressed air in the air passage, through the cryogenic heat exchanger, into the cryogenic liquid in the cryogenic liquid passage to provide cooled air;
• and
• directing the cooled air into a housing, wherein the component of the engine is disposed within an internal chamber of the housing.

• and
• directing the compressed air through a refrigeration heat exchanger of a refrigeration cooling system to precool the compressed air, wherein the refrigeration heat exchanger is upstream of the cryogenic heat exchanger.
