Résumé

Inspection of several domestic industrial enterprises showed that majority of enterprises of produce storage exploited the systems with direct ammonia supplying into cooling devices at low level of industrial safety. Some enterprises use systems with cooling batteries for rooms refrigeration that requires more ammonia capacity. Some enterprises use safety systems of indirect refrigeration with coolants; using such systems leads to electric power overrun up to 20%. In most cases it is linked with errors of systems design. The great influence of exploitation factors on electric power overrun was noted, especially presence of air in the systems maintaining the air temperature in rooms lower minus 20°C. It was noted that low temperature processing enterprises begun to use cascade systems operating with CO2 and ammonia that allowed assuring high energy efficiency together with high level of industrial safety. The necessity of control of gas contamination by refrigerants used in the engine-room and technological premises was marked.
