Expansion machines for carbon dioxide based on modified reciprocating machines.
Author(s) : HEIDELCK R., KRUSE H.
Summary
Expansion machines can improve the efficiency of refrigeration cycles especially when applying carbon dioxide as the refrigerant. To achieve this, the authors favour the application of modified reciprocating machines. In contrast to reciprocating compressors where self-acting valves are used, piston-position-dependent inlets and outlets have to be applied for reciprocating expansion machines. A concept is presently being investigated with modified wobble plate or swash plate type compressors. This simple design system without electronic devices is discussed.
