New ammonia technology for heat pumps.

Author(s) : KORFITSEN E., CHRISTENSEN A.

Summary

The superior properties of ammonia as a refrigerant are well known, but 2,500-kilopascal compressor design pressure has prevented the use of ammonia in high temperature heat pumps. A range of 4,000-kilopascal compressors has therefore been developed, thus making ammonia an attractive alternative in the traditional working area of R12 heat pumps. The compressor construction is described, and Norwegian 2,500-kilopascal and 4,000-kilopascal ammonia heat pumps are presented. Examples are given in fish industry, wood driers and for district heating.
