What is claimed is: 1. A refrigeration system, comprising:a heat exchanger;an asymmetric scroll expander havinga fixed scroll element;an orbiting scroll element engaged with and movable along a circular orbit relative to the fixed scroll element, wherein the orbiting scroll element is about one-half wrap shorter at each end relative to the length of the fixed scroll element;an inlet port configured to receive a refrigerant from the heat exchanger;a first expansion pocket defined between the orbiting scroll element and the fixed scroll element that becomes closed to the inlet port at a first relative engagement position of the orbiting scroll element and the fixed scroll element; andan outlet port disposed proximate a terminal end of the orbiting scroll element.
