Abstract

The work aims to solve the current problem of high energy consumption of refrigerated transport equipment. Energy-saving and consumption-reducing improvement technologies were introduced to develop new heat insulation and energy storage materials and design new passive modular cold storage transport equipment based on the comprehensive analysis of the energy consumption composition of refrigerated transport equipment. In terms of heat-insulating performance, a composite enclosure structure with high reflectivity was developed, and experiments showed that the peak temperature of the outer surface dropped by a maximum of 14.9% after structural optimization, with the average temperature dropping by a maximum of 7.6%. The peak temperature of the inner surface dropped by a maximum of 5.1%, with the average temperature dropping by a maximum of 5.0%. In terms of refrigeration performance, a series of non-toxic high-latent heat accumulators were developed, along with a modular and connectable cold storage device, and corresponding application models were proposed. Experiments showed that when the amount of accumulator used was 1 t, the effective temperature control of the 9.6 m refrigerator van reached more than 10 d, meeting the needs of long-distance transport. In terms of economy, the average annual refrigeration cost of the new passive modular cold storage transport equipment was 79.6% lower than that of the traditional mechanical refrigerated vehicle. The study can provide reference for the use of new energy in refrigerated transport equipment.
