Development of High-Insulation Container with "No Room Temperature Exposure"

[Asia Economy Reporter Junho Hwang] The Korea Railroad Research Institute announced on the 8th that it has developed a battery hybrid smart high-insulation container capable of maintaining a cold chain (low-temperature logistics).

This container is a 20-foot standard refrigerated container, which has completed insulation and refrigeration air conditioning performance tests according to ISO insulation container performance test regulations, and has secured safety and applicability through road test operations. It can maintain an internal temperature as low as minus 20 degrees Celsius using the built-in battery without external power supply. When set to an internal temperature of 7 degrees Celsius, it can maintain the temperature for more than 72 hours at room temperature. In particular, the container walls use vacuum insulation material that has insulation performance about eight times better than general insulation materials, resulting in high insulation performance.

Before the development of this container, the only refrigerated container using a battery was the "Hyoukan SO" developed by Japan's JR Freight. It can maintain temperature for about 40 hours in spring and about 30 hours in summer.

Lee Seok, head of the logistics technology research team at the Korea Railroad Research Institute, said, "The developed refrigerated container features high efficiency by maintaining freezing and refrigeration for a long time through a battery and power-driven refrigeration air conditioning system and high-insulation wall technology," adding, "We are planning railroad and road test operations for commercialization."
