Technical status and development trend of heat exchanger for industrial and commercial refrigeration and air conditioning
In order to further promote the development of performance and reliability of heat exchangers for industrial and commercial refrigeration and air conditioning in China,as well as research on refrigerant substitution,based on the investigation of heat exchangers for industrial and commercial refrigeration and air conditioning,the technical status of shell-and-tube heat exchangers,plate heat exchangers,finned tube heat exchangers,concentric tube heat exchangers and micro-channel heat exchangers were described.At present,China's heat exchangers for industrial and commercial refrigeration and air conditioning have made great progress in enhanced heat exchange technology,processing and manufacturing technology,however,with the diversification of demands in the application market,higher technical requirements have been proposed for heat exchangers.In the future,the research and development of heat exchangers should start from aspects such as material conservation,research and development of new refrigerants,and intelligent processing and manufacturing,in order to improve the heat transfer efficiency of heat exchangers and save material costs,and adapt to the development trend of refrigerant substitution in the industry.
