Application and Development of Ammonia Refrigeration Technology

In this paper, the characteristics of ammonia refrigerant are described. The application status and existing problems of ammonia refrigeration systems both in China and abroad are analyzed. The development trends of ammonia refrigeration technology including system optimization, improvement of control technology, safety guarantee, and miniaturization of ammonia systems are discussed. Moreover, some main problems to be solved according to safety requirements of Design Codes and Manuals of ammonia refrigeration systems are indicated. In addition, the ideas of simplifying ammonia systems are presented. It is suggested that the development of smallscale ammonia refrigerant compressors should be speeded up, and the theoretical and experimental studies both on ammonia refrigeration equipment and on practical applications should be emphasized in China.
