Analysis on Energy Saving in Cross-Critical CO2 Cycle Refrigeration and Development Localization
This paper mainly analyzes the high efficiency characteristic of cross-critical carbon dioxide cycle refrigeration, especially when this refrigeration system works as a heat pump. When this refrigeration system is used as heat recycle system with larger different temperature and high level temperature, the solely superiority and energy saving capability of this system will reveal. However, the development localization of cross-critical CO2 cycle refrigeration system also exists, which includes immature cross-critical CO2 flow and heat exchange theory, and seal problem of compressor, expansion ratio of expansion equipment.
