RESEARCH STATUS OF REFRIGERANT DISTRIBUTION IN REFRIGERATION SYSTEM

It is commonly recognized that distribution and migration characteristics of refrigerant properly in refrigeration system is important for refrigeration system optimization. This paper surveys researches of refrigerant distribution and migration characteristics of refrigeration system, analyzes conclusions of researches in steady and dynamic state. It also points out refrigerant distribution and migration characteristics of refrigerant after shutdown of compressor for a long time is crucial to improve precision of dynamic simulation, direct diagnosis and improve performance.
