Résumé

To carry out technological processes in the food-processing industry, temperatures of the cooling medium as low as -30/35°C are required, which correspond to evaporation temperature of the refrigerant -40/-45°C. To increase the efficiency of processing, further reduction of evaporating temperature of the refrigerant is often needed. Currently used pump circulation systems with ammonia supply to refrigerating devices are dangerous for service personnel and people, who live nearby, because of a large amount of ammonia in the system. For the solution of this problem, a cascade refrigerating system CO2/NH3 has been offered. The authors determine a range of evaporation temperatures, when the use of a cascade scheme CO2/NH3 is more efficient than traditional ammonia pump circulation systems due to less power consumption, for a set of real enterprises.
