To provide a high cold-storage/cold-reserving performance by improving a heat-transfer efficiency, related to a cold storage unit for a cold reserving chamber.
A cold storage agent and a cooling unit 7 are provided. Here, the cold storage agent is packed into a freely deformable packing bag to form a cold-storage agent packing body 20 which is so arranged as to face a heat transfer pipe 8, while the cold-storage agent packing body 20 is pushed and urged toward the heat transfer pipe 8 side by energization members 32 and 33. With this configuration, the cold-storage agent packing body 20 is brought into tight contact with the heat transfer pipe 8 so that the heat transfer efficiency from the heat transfer pipe 8 to the cold storage agent 22 side is significantly improved, for improved heat accumulation performance.
