| Abstract: | The performance optimization of a regenerated air refrigeration cycle with variable-temperature heat reservoirs was studied by taking the cooling load density as the optimization objective. The irreversible losses considered include the heat resistance losses in the hot- and cold-side heat exchangers and the regenerator, the irreversible compression and expansion losses in the compressor and expander, and the pressure drop losses in the piping. The analytical relations of the cooling load density and coefficient of performance of the cycle were derived. The effects of pressure ratio, the allocation of heat exchanger inventory and heat capacity rate matching between the working fluid and the heat reservoirs on the cooling load density of the refrigerator were demonstrated with detailed sample numerical examples. |
