Abstract
An energy conversion apparatus for a freezer includes a housing having a first region therein for receiving liquid CO2 for providing potential energy; a movable member rotatably mounted to the housing and having a second region in fluid communication with the first region and constructed to receive the liquid CO, for providing kinetic energy from which mechanical work is provided to rotate the movable member; and a discharge member connected to the movable member and having a third region in fluid communication with the second region, the third region continuing the mechanical work when exhausting the liquid CO2 such that the liquid CO2 is changed to a CO2 snow.

An energy conversion apparatus for a freezer, comprising:
- a housing having a first region therein for receiving liquid CO2 at a first pressure and at a first energy state for providing potential energy;
- a movable member rotatably mounted to the housing and having a second region in fluid communication with the first region, the second region constructed to receive the liquid CO2 for changing to a second pressure less than the first pressure, and a second energy state less than the first energy state for providing kinetic energy from which mechanical work is provided to rotate the movable member;
- and
- a discharge member connected to the movable member and having a third region in fluid communication with the second region, the third region continuing the mechanical work when. exhausting the liquid CO2 at a third pressure less than the second pressure, and at a third energy state less than the second energy state such that the liquid CO2 is changed to a CO2 snow.
A method of energy conversion for a freezer, comprising:
- 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.
