1. A system, comprising:
a solar-powered steam Rankine cycle (SRC) subsystem configured to receive solar energy, convert the solar energy into thermal energy, and store the thermal energy;
an ejector refrigeration cycle (ERC) subsystem configured to
generate an electrical power based on the thermal energy, and
provide a first refrigeration effect with a first range of temperature based on the thermal energy;
an absorption refrigeration cycle (ARC) subsystem configured to provide a second refrigeration effect with a second range of temperature based on the thermal energy;
a brine refrigeration cycle (BRC) subsystem configured to
generate and store when there is no cooling demand, and
provide a third refrigeration effect with a third range of temperature based on the electrical power generated by the ERC subsystem and the ice being melted; and
an adsorption refrigeration cycle (ADRC) subsystem configured to provide a fourth refrigeration effect with a fourth range of temperature based on the thermal energy,
wherein the SRC comprises a heat recovery vapor generator (HRVG) configured to generate superheated steam for the ERC subsystem;
wherein the ERC subsystem includes a steam turbine (T) configured to generate the electrical power based on the superheated steam from the HRVG of the SRC subsystem; and
wherein the BRC subsystem includes a compressor (COMP) powered by the electrical power generated from the steam turbine of the ERC subsystem and configured to generate high-pressure superheated refrigerant vapor.
