Abstract
In a refrigeration system, an asymmetric scroll expander has an orbiting scroll element engaged with a fixed scroll element. The orbiting scroll element and fixed scroll element can define a first expansion pocket and a second expansion pocket at positions relative to one another.
Claims38
An asymmetric scroll expander comprising:
- an orbiting scroll element engaged with a fixed scroll element;
- a first expansion pocket defined between the orbiting scroll element and the fixed scroll element at a first relative engagement position;
- and
- a second expansion pocket defined between the orbiting scroll element and the fixed scroll element at a second relative engagement position.
1 more element
A refrigeration system comprising:
- a refrigerant expansion device comprising a means for reducing the axial pressure force variation during expansion of a refrigerant;
- a heat exchanger having an outlet port in fluid communication with the expansion device;
- and
- a compressor in fluid communication with the evaporator and the heat exchanger.

An asymmetric scroll device comprising:
- an orbiting scroll element engaged with a fixed scroll element;
- a first pocket defined between the orbiting scroll element and the fixed scroll element at a first relative engagement position;
- and
- a second pocket defined between the orbiting scroll element and the fixed scroll element at a second relative engagement position.
1 more element
A method of expanding a refrigerant comprising introducing a transcritical fluid at a first pressure into an asymmetric scroll expander.
A method comprising:
- expanding a transcritical fluid in at least one expansion pocket of an asymmetric scroll expander to generate mechanical work;
- and
- delivering the mechanical work to a rotating shaft.
