以降压为目的的CO2混合工质制冷系统研究进展
Research progress on refrigeration systems using CO2 mixture refrigerant to reduce its cycle pressure
摘要
Abstract
Carbon dioxide is increasingly attracting attention as a natural refrigerant due to its environmental friendliness(ODP=0,GWP=1),large unit volume refrigerating capacity and good heat transfer performance,etc. However,it is mainly used in transcritical refrigeration cycle due to limitation of its physical properties and working conditions. The operating pressure in the high pressure side of the transcritical CO2 cycle may exceed 12MPa,which results in high requirements for safety and manufacturing costs. In this paper,we summarized current CO2 refrigerant systems using CO2 mixture refrigerant to effectively improve the problem of its high operating pressure,reviewed the research progress of refrigeration systems using CO2mixture refrigerant to reduce its cycle pressure, and analyzed the characteristics of the CO2 mixture refrigeration systems,including the transcritical refrigeration cycle system,auto-cascade refrigeration system and compression-absorption coupled cycle system. Furthermore,we pointed out the development prospect of the refrigeration systems using CO2 mixture refrigerant for depressurization,and discussed the main research directions of the CO2 refrigeration systems in the future.关键词
