Ecological and thermoeconomic analysis of the prospects for the use of ammonia in refrigeration equipment

Ecological, thermal and economical analysis was used in the study of prospects far the use of ammonia in new generation of refrigeration equipment. This method uses new efficiency criteria based on the evaluation of minimum level of emission of greenhouse gases during production of cold. The conclusion ahout good reasons far the use of ozone safe refrigerants was made within the frame of systems approach the essence of which consisted in consecutive increased complication of the objects of investigations. The analysis has shown that even taking into account additional engineering measures necessary for ensuring a safe use of ammonia this refrigerant has no alternative from ecological and energy point of view.
