摘要： It is a method for storing and recovering energy proposed formed in which anair liquefaction product in an energy storage period (LAIR) and in an energy recoveryperiod using at least part of the air liquefaction product (LAIR) without supplying heat

from an external heat source, a pressure stream is formed and is work expanded , Themethod includes, among other things, the formation of the air liquefaction product (LAIR)air (AIR) in an air conditioning unit (10) to condense at least by means of an adiabaticallyoperated compressor means (12), the adiabatically operated compressor means (12)downstream from (in this compressed air lead aIR) having a first and to form a secondpartial flow and the first and the second partial stream in parallel (through a first heatstorage means 131) and a second thermal storage device (132), where (in the

compression of the air heat aIR) produced is stored at least in part becomes. To form thepressure stream a Entflüssigungsprodukt (HPAIR) is generated, inter alia, at least part ofthe condensation product (LAIR). The pressure stream is performed at the work-performing expansion by a first expansion device (61) and a second expansion device (62)and in each case released. Upstream of the first expansion device (61) is in this case in thefirst heat storage device (131) transfer stored heat to the pressurized stream andupstream of the second expansion means (62) is in the second heat storage device (132)transfer stored heat to the pressurized stream. A system (100) is also subject of thepresent invention.
