Compressed air energy storage system for integrated absorption type refrigeration

The utility model discloses a compressed air energy storage system for integrated absorption type refrigeration, and belongs to the field of compressed air energy storage. The system mainly comprises a compressed air energy storage subsystem, an absorption type refrigeration subsystem and a gas turbine power generation subsystem, wherein the compressed air energy storage subsystem adopts a multi-stage compression and interstage two-stage cooling mode; normal-temperature water exchanges heat with high-temperature air from an outlet of a first-stage air compressor to generate steam; the steam is conveyed into an absorption type refrigeration machine; generated low-temperature water enters a second-stage cooler to perform secondary cooling on compressed air; a heat regenerator is arranged in the gas turbine power generation subsystem; gas turbine exhaust is used for heating high-pressure air from an outlet of an air storage chamber; the high-pressure air enters a combustion chamber for hybrid combustion with natural gas so as to generate high-temperature and high-pressure fuel gas; the fuel gas enters a turbine for doing work, and generated electric energy is conveyed into a power grid. The compressed air energy storage system fully makes use of indirect cooling heat in an air compression process and afterheat of gas turbine exhaust, so that the power consumption and heat consumption are effectively reduced, and the total efficiency of the whole system is improved.
