Infrared radiation heating principle and characteristics ofChinas abundant natural gas resources, with the national energy strategy, technology transfer and the exploration and exploitation of the continuous development of western China in recent years proven and successful development of a number of high-quality natural gas fields, has been the formation of the Tarim, Qaidam, Shaanxi-Gansu-Ningxia and Sichuan, Chongqing, four natural gas fields at national level, already the basis for the development of gas industry and conditions. It is reported that natural gas as a clean and efficient energy and high-quality chemical raw materials, energy structure in the world the proportion has reached 24%, while in China, the current energy mix of natural gas in the proportion of only 2.2%. According to China National Petroleum Corporation in 2000, Zheng Hu, deputy general manager of China International Oil and Gas Conference news conference that China has been the development and utilization of natural gas for the early 21st century energy structure optimization and upgrading of the oil industry focus, for ten years about the time, so that natural gas in Chinas energy consumption structure in the proportion from the current 2.2% to 8%, Tarim Basin in Xinjiang as the countrys largest natural gas fields and the birth of the implementation of the project, together with the development of offshore oil and natural gas and natural gas abroad, including the use of 2010 is expected to achieve this objective. Is no doubt that to develop the national situation, the natural gas industry, natural gas as a clean energy in industrial production and national life in the proportion of energy consumption will grow. Under such circumstances, how to respond to national policy to better promote the natural gas industry in the application of HVAC problems, is facing the industry, especially in the HVAC equipment manufacturers, sales staff and design business before an issue.First, the principle of infrared radiation heating.Gas-fired infrared radiant heating system consists of one or more independent vacuum system. Each vacuum system includes a vacuum control system, a certain number of generators and heat exchangers. Heat exchanger system of steel pipes from 100mm diameter pipeline linking and coverage of the above in its high-performance aluminum alloy constitutes a sounding board. The system uses natural gas, liquefied petroleum gas or gas-gas heat and combustion by the generator, the heat generator in the air, through the use of centrifugal fans or pumps the role of the heated air and combustion products of the radiation transport tube, radiant tube heated to a certain temperature, produce far-infrared radiant tube outside heat transfer. The system is based on the sun heating the Earths surface created by the principles of design, supply of solar energy to the Earths analysis concluded that the electromagnetic spectrum: wavelength 10 - 8 microns (m) below for the cosmic rays, wavelength in more than 5 108m for the sound to wave, thermal radiation mainly in the wavelength range of 2 - 10m between. The simulation of the solar system can produce only by radiation and heat conduction medium of air) for some non-thermal heating of the radiation (wavelength 2 - 12m). Therefore, the direct heating of the system object space rather than heating the air, but heating objects: space, staff, equipment, tools. These heating objects in accordance with its own characteristics of physical and chemical structure to absorb and store energy received, and then exposed to air through its surface to the air space heating heat transfer, which can solve the technology sector has been beset all HVAC kinds of military, civilian tall warehouse space heating and other problems. Infrared radiant heating is similar to solar radiation, infrared is the part of the electromagnetic paragraph. Different wavelengths of the electromagnetic waves are exposed to the objects will produce different effects. Wavelength such as 0.76-1000um between the electromagnetic wave, especially in the wavelength range of 0.76-40um, with a non-dispersive and thus the energy concentration of a significant thermal effect, that is, infra-red. The sun heating the earths surface with different heating radiator, it does not require heating the atmosphere, but by solar radiation to directly heat the Earths surface. Through infrared radiation, radiation to the region of direct heating, thermal radiation can be of concrete floors, and absorbed a variety of objects, and a second radiation of these objects in order to heat other objects around. Not only that, but also infra-red object or the human body through a certain degree of depth of surface layer, which from the inside of the object or the body heat, this system is also referred to as artificial solar heating system. Gas-fired infrared radiant heating of the radiation intensity, effective. Radiant heating in the environ
