Development of a Scroll Expander for the CO2 Refrigeration Cycle

A New Ericsson Cycle Comprising a Scroll Expander and a Scroll Compressor for Power and Refrigeration Applications

Future of the Refrigeration Cycle with Expander

The refrigeration cycle with the thro~tling device has moe work power consumption and less refrigeration capacity than tha~ with the expander. It is S':Jggested that substituting the expander for the throttling device in the refrigeration cycle should be the efficient way for saving the energy of the refrigeration system. Up to now, the design and ~anufacturing of the two-phase expander seems t...

Numerical Simulation of a Scroll Expander for Use in a Rankine Cycle

A Twin Screw Combined Compressor And Expander For CO2 Refrigeration Systems

Recent interest in natural refrigerants has created a new impetus for studies of CO2 as a working fluid in vapour compression systems for refrigeration and air conditioning. Two major drawbacks to its use are the very high pressure differences required across the compressor and the large efficiency losses associated with the throttling process. To overcome the throttle losses, a number of propo...

Development of Large Capacity CO2 Scroll Compressor

CO2 refrigerant with a high operating pressure has a large difference between the suction and discharge pressures in compressors. Because of a load increase, the high performance and high reliability of compressors are required. Compared to the scroll compressor employing the conventional refrigerant, the thrust load increases in the CO2 scroll compressor. Therefore the design of thrust bearing...
