Micro　compressed　air　energy　storage　systems　are　a　research　hotspot　in　the　field　of　compressed　air　energy　storage　technology.　Compressors　and　expanders　are　the　core　equipment　for　energy　conversion,　and　their　performance　has　a　significant　impact　on　the　performance　of　the　entire　compressed　air　energy　storage　system.　Scroll　compressors　have　the　advantages　of　small　size,　low　noise,　light　weight,　low　vibration,　long　service　life,　continuous　and　stable　gas　transmission,　and　reliable　operation.　This　article　builds　a　micro　compressed　air　energy　storage　system　based　on　a　scroll　compressor　and　studies　the　effects　of　key　parameters　such　as　speed,　torque,　current,　and　storage　tank　pressure　on　the　temperature　difference,　pressure　ratio,　energy　consumption,　and　efficiency　of　the　scroll　compressor.　The　experimental　results　indicate　that　the　power　consumption　of　the　scroll　compressor　shows　an　increasing　trend　with　the　increase　in　current,　torque,　and　gas　storage　tank　pressure.　The　isentropic　efficiency　of　a　scroll　compressor　shows　a　decreasing　trend　with　increasing　current,　torque,　and　storage　tank　pressure.　The　maximum　values　of　power　consumption　and　isentropic　efficiency　of　the　scroll　compressor　are　3427　W　and　90.8%,　respectively.
