Abstract

AIM. The paper discusses the process environment of liquefied natural gas (LNG) cold energy recovery from the fuel system of a standalone refrigerated container (reefer container). To evaluate the efficiency of LNG cold energy utilization.

MATERIALS AND METHODS. The authors determined the refrigeration potential of the LNG regasification process and a developed a thermal design of the refrigeration plant.

RESULTS. The paper describes a cascade refrigeration plant with LNG and carbon dioxide circuits. The authors assess the expected effect of cold energy utilization during LNG regasification in the refrigeration system of a refrigerator.

CONCLUSION. The results allow to assess the efficiency of LNG refrigeration potential utilization in refrigerator vehicles.
