■  Carbon Crystal Ground Heating System （CCGHS）

CCGHS is technically known as the ground heating system of low-temperature and far-infrared of carbon crystal. It has been developed to be a new-type of heating system based on carbon crystal exothermic boards （CCEBs） as key heating parts. With the competitive character of even heating of CCEBs, CCGHS guarantees that the entire installed ground will heat up evenly and consistently comparing with traditional ground heating products. It also performs a good thermal balance. It proves the brilliant use of high-tech development in the field of civilian products. It has been improved to be the big cheese in the ground heating industry.

■  Exothermic Principle of CCGHS

The reason of quick heating-up of carbon crystal boards relies on the efficient electric power conversion that 100％ electric power input has converted into more than 60％ heat conduction power and over 30％ infrared radiation power. This double-exothermic principle has two features: 1. quick heating-up; 2. efficient absorption of heat power.

■  Exothermic path of heat conduction

Even carbon crystal boards have been laid underneath the ground decoration materials. In the electric field, carbon crystal molecules do the movements of Brownian motion producing heat via friction, which also increases the temperature of the boards. In this process, heat continuously gets through the covers of the boards and approaches the heat insulations on the back of carbon crystal electric-power materials, which reflect the heat to the covers of exothermic surfaces rising the surface temperature.

It only costs 2 to 4 minutes to reach the thermal balance between exothermic objects and heat insulations performing the heat radiation of consistent temperature. Then the heat is gradually transferred to the surface air of the rooms via exothermic boards. According to the pyrological theory that “cold air fall and hot air rise”, the hot surface air rise quickly replacing the cold air and forming the circulation between hot air and cold air in the rooms. Eventually, the vertical convection-reactions of top-air and bottom-air increase the room-temperature.

■  Exothermic path of infrared radiation power

In the electric field, carbon crystal boards produce a mass of upwards-infrared of the wavelengths from 8ｕto 15ｕ. When receivers absorb infrared, the radiation power is converted to be heat raising the temperature. Its principle is similar as “everything is under the sun”, because the sun breeds every single thing on the earth.

The practice proves that the infrared heating system generally needs 2℃ lower than the air convection heating system does to make people comfortable. Therefore, through the installation of CCGHS in the room, people will feel warm and comfortable rather than dry. Besides, CCGHS also has great performance at the low-cost of power with the assistant of infrared heating parts.

（Remarks:①In 1827, Scottish botanist Brown （R.Brown,1773-1858） observed minute particles within vacuoles in the pollen grains executing a continuous jittery motion while examining pollen grains and the spores of mosses and Equisetum suspended in water under a microscope. This phenomenon is now known as Brownian motion.

② Heat Transport: heat is transported from warmer objects to cooler objects. It is also transferred from warmer areas to cooler areas of the same substance. Heat transport has three ways: conduction, convection and radiation. Conduction: If different parts of an isolated solid are at different temperatures, heat will flow from the hot places to the cold ones until eventually all is at the same temperature. Convection: it is gravitationally-induced heat transport, driven by the expansion of a fluid on heating. The hot expanded fluid has lower density, so will rise to the top of colder, and therefore denser, fluid. For example, water in a kettle heated from below: hot water will rise in a central column, spread through the top layer, cooling, then flow back down around the outside. Radiation: it is in the infrared, wavelengths longer than those of the visible spectrum at the room temperature.）
