| Abstract: |
| Based on sustainable development concept, consideration of natural quality of refrigeration system, a new evaluation methodology has been proposed for the environmental performance of refrigeration and heat pump system with conjunction of the natural quality and the thermodynamic perfectibility. According to the quantitative results of refrigeration nature degree evaluation indexes, there is large room to advance the natural quality of each system. And using the natural quality methodology to evaluate the refrigeration system can show the direction for improving the system. |
