In recent years, variety of refrigerated and fresh cargoes have been consolidated on a specially designed truck of home delivery services in which compartments are separated with different temperatures. Regarding the need of the consolidation in cold supply chain, the authors conduct experiments by which two different temperatures of spaces are created in a reefer container by partitioning in the center of the container and taking in open air. A model of estimating temperatures in the container is formulated according to measurement of the experiment. Under the estimated temperatures of the model, the authors conduct a proof experiment by which a frozen cargo and a fresh cargo are stored in the container and investigate that quality of the cargoes are preserved. Results of the research indicate that ordinary reefer containers may be utilized for consolidating cargoes that need to control temperature differently in cold supply chain.
