Insulation literally means to "cut off" heat, while heat shielding refers to blocking the transmission of heat through waves. Even if you create a "heat shield box" using heat shielding materials, it will only be effective to the extent of preventing radiant heat from causing the internal temperature of the box to exceed the outside temperature. By "insulating," it is necessary to delay heat conduction and create a temperature difference between the internal temperature of the box and the outside temperature. 【Overview】 ■ Insulation: To "cut off" heat ■ Heat shielding: To block the transmission of heat through waves *For detailed Q&A content, please refer to the related links.

In summer, when the outside temperature is always higher than the temperature inside the box, heat flowing in from outside is absorbed by refrigerants and heat storage agents. Heat absorption occurs when the refrigerants and heat storage agents undergo a phase change from solid to liquid, so the refrigerants and heat storage agents used need to be pre-frozen, that is, in a solid state. *For detailed Q&A content, please refer to the related links.

In winter, when the outside temperature is always lower than the temperature inside the box, heat that has flowed out is compensated for by radiating it using refrigerants or heat storage agents. Radiation occurs when the refrigerants or heat storage agents undergo a phase change from liquid to solid, so it is necessary to prepare the refrigerants or heat storage agents in liquid form in advance. *For detailed Q&A content, please refer to the related links.

When the outside temperature consistently exceeds the temperature inside the box, it is necessary for the cooling agents and heat storage agents to absorb and release heat. In this case, both liquid and solid states of the cooling agents and heat storage agents are used. When the temperature inside the box is lower than the outside temperature, the solid cooling agents and heat storage agents are activated, and in the opposite case, the liquid cooling agents and heat storage agents are used. If you want to operate under the same conditions throughout the year, regardless of the season, this combination of cooling agents and heat storage agents will be used in the design. *For detailed Q&A content, please refer to the related links.

"A larger cooler box is more efficient at keeping things cold." If someone told you that this is proven by polar bears, would you believe it? This story is actually true. What commonality could there possibly be between polar bears and cooler boxes? For those who find it hard to believe, let me first tell you about polar bears. Polar bears are characterized by their very large size. So why are they so big? In 1847, a German scientist named Christian Bergmann proposed the theory that "larger animals have an increase in body surface area that is less than the increase in volume. Therefore, they lose less heat through their body surface, which is advantageous in cold regions." This is known as Bergmann's Rule, and it is the main reason why polar bears are so large. In other words, larger animals have better heat retention efficiency. *For detailed Q&A content, please refer to the related links.

Indeed, the cost of cool delivery has been rising. I have heard that in some regions, due to quantity regulations, there are cases where transportation cannot be arranged. There are only two means of transporting cargo under refrigeration in the world. One is the method of using refrigerated trucks, and the other is the method of using refrigerated boxes. Cool delivery is nothing other than the method of using refrigerated trucks, but as a way to transport over long distances in a one-way manner, cool delivery is a very convenient and inexpensive option. *You can view the detailed Q&A content from the related link.
