摘要

The paper gives an overview of ammonia industrial refrigeration plants in Balkan countries. A brief chronology of the development of industrial refrigeration in the countries of the former Yugoslavia and current status of refrigeration equipment which has been dominating in the Balkan market for the last fifty years are presented. Based on personal insights of author acquired within many years of experience in the planning, designing and construction of industrial refrigeration installations, and including appropriate examples, the basic technical features of the relevant systems are given. In particular analyzed are the problems related to the renovation and reconstruction of existing ammonia installations, with special emphasis on the charging and the possibility of improving energy transformation of refrigeration systems. A short summary of suggestions for improving the existing status of ammonia refrigeration systems in the Balkan region is also stated.
