Technology that prevents heat from escaping

Vacuum insulation technology removes air from a space to create a vacuum, thereby increasing the thermal insulation effect.

Vacuum insulated bottles are one example of a product that demonstrates this technology.
In a vacuum bottle container, a vacuum is created in the double space, resulting in very high thermal insulation performance.
This keeps the contents warm or chilled for longer periods of time and contributes to energy conservation.

How is heat conducted?

The change in temperature around us is mainly related to the three principles of heat transfer: conduction, convection, and radiation.
We will explain each of these three phenomena.

Conduction is defined as a phenomenon of heat transfer through matter. When part of an object is heated, molecular motion in the heated part becomes active.
Collision of these molecules with each other results in the transfer of energy from the high-energy molecules to the low-energy molecules. This process is known as “heat conduction” and the numerical value expressing how well an object conducts heat is termed “heat conductivity”.
For example, when a metal spoon is placed in hot soup, even the spoon handle gets hot because of heat conduction.

Convection is defined as a phenomenon in which hot air or liquid rises and cold air or liquid falls.
When air is heated, it expands and becomes less dense. The heated air is less dense than the surroundings, and rises by the action of buoyant force. The rising heated air transfers heat to the surroundings by heat conduction.
For example, when a room is heated, warm air rises and cold air sinks. If the air is forced to circulate with a fan in a room, the whole room can be heated efficiently.

The transfer of heat energy caused by electromagnetic radiation is known as “radiation”, which can be defined as a phenomenon of heat transfer between objects without direct contact.
Despite the absence of direct contact, space is not a vacuum, and the heat of the Sun reaches the Earth via electromagnetic waves such as infrared rays. This process is known as radiation, and it is responsible for the heating of the Earth, as well as various life activities and atmospheric phenomena. The process of radiation involves the transfer of heat energy, with the vacuum of space serving as the medium for this transfer.
For example, the phenomenon of the Earth being warmed by electromagnetic waves such as infrared radiation, as a result of the Sun’s energy, can be considered an example of radiant heat.
