Abstract

A combined power and refrigeration cascade system that includes an electric power system (PS) that produces both electric power and medium-to-high-grade waste heat. To reduce energy consumption by a load having a computer chip, the load is powered by a power source and thermally coupled to a refrigeration system, which is also powered by the power source. The refrigeration system is thermally coupled to an absorption system, which is configured to remove heat rejected by the refrigeration system. The refrigeration system and the absorption system are in a cascaded arrangement such that the refrigeration system condensing temperature is less than twenty degrees Celsius. In particular, absorption chillers of the absorption system and vapor-compressors of the refrigeration system are in a cascading arrangement that produces subzero cooling.
