Abstract (en)

[origin: EP2884206A1] In order to overcome the problems that earlier apparatus and earlier methods have experienced, an apparatus (100) and a method of energy conversion for a freezer are proposed, comprising: - providing liquid carbon dioxide (CO 2 ) at a first pressure and at a first energy state to a first region (A) for providing potential energy; - expanding the liquid carbon dioxide (CO 2 ) to a second pressure less than the first pressure, and to a second energy state less than the first energy state in a second region (B) in fluid communication with the first region (A) for providing kinetic energy for performing mechanical work in the second region (B); and - exhausting the liquid carbon dioxide (CO 2 ) as a carbon dioxide (CO 2 ) snow at a third pressure less than the second pressure, and at a third energy state less than the second energy state from a third region (C) in fluid communication with the second region (B).
