られる。[0004] The requirements for this type of insulated packing box include:
There is a demand for shortening the pre-cooling time of a freezer of a freezer truck and increasing the internal volume of the refrigerator. Here, the pre-cooling time is a time for cooling the freezer to a predetermined temperature (low temperature) before loading the load.
The shortening needs to reduce the intrusion of heat from outside air into the freezer. For that purpose, it is necessary to improve the heat insulation of the freezer wall. The storage volume expansion is particularly in the width direction. The outer width of the freezer is regulated by law.
Therefore, in order to increase the internal size, it is necessary to reduce the thickness of the heat insulating material. Assuming that the heat insulation performance is the same as the current case, it is necessary to improve the heat insulation of the freezer wall. Therefore, in order to satisfy these needs, as one method for improving the heat insulating property of the wall material, application of a vacuum heat insulating panel having a lower thermal conductivity than the current foamed plastic foam can be considered.
