Potential of 1/2 cycle refrigeration system for food transport application

Abstract

Maintaining the quality of food products from an agricultural land and farms to the final consumer is usually conducted through the car-cooling box. However, as long as the refrigeration equipment takes energy from the car engine, it will significantly increase fuel consumption. Therefore, this paper presents the concept of 1/2 cycle refrigeration system on LPG-fueled vehicles to reduce fuel consumption due to the load of the refrigeration system. From the numerical study, the 1/2 cycle refrigeration system on LPG-fueled vehicles is potential to be applied on the car-cooling box as the secondary refrigeration system. This system provides a considerable potential cooling effect of 0.8 kW at LPG flow rate of 2.4 g/s.
