Abstract
A method of energy conversion for a freezer includes providing liquid CO2 at a first pressure and at a first energy state to a first region for providing potential energy; expanding the liquid CO2 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 in fluid communication with the first region for providing kinetic energy for performing mechanical work in the second region; and exhausting the liquid CO2 as a CO2 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 in fluid communication with the second region.
