In recent years, Fujian electricity supply market tensions have steadily eased, the situation of supply exceeding demand in electricity.With the continuous development of the national economy, senior guesthouse in the south, high-grade office building in winter heating increasingly common, and the energy to electricity for heating equipment will gradually become mainstream.To warm the system is in the past few years China's rapid development of a new power heating system.In the northern region being the promotion, then its application in the future how our province, worth exploring.

1 outlines radiation to warm heating on heat-ray (electromagnetic waves in the long 0.1-100 μ m) thermal radiation emitted mainly of both a comfortable and energy-saving heating, low-temperature radiation surface temperature below 80 ° C. It is the use of buildings within the top surface, floors, walls or other surface heating systems, radiant heating in the total heat transfer, the proportion of heat and radiation usually accounts for about 50%.At the same time, it is a public health conditions and relatively high standard of comfort heating.Some countries in Europe and the United States known as the Green health heating.As early as the 1930s, some senior foreign residential applications began.Various types of construction in North China mainly to water convection heating system (convective cooling of the total calories to 75 percent) as the main form of heating.The radiation to warm heating is common in China, high-temperature systems, and more focused on large-scale construction of industrial plants and facilities in civilian residential, hotels and office buildings, and other senior buildings rarely used.In recent years, with diversified forms of heating, low-temperature electric heating in China's rapid development, almost all types of construction are examples of the application of heating, but the results mostly very good.

To warm the system is the power for energy to electric-resistance heat for the film in, beyond infrared heat in the form of indoor heating.First of all far-infrared thermal heating indoor dense objects (walls, floors, the human body, etc.) and then heat objects pass air, indoor air temperature increases lag behind the body temperature, reduce the environmental radiation on the human body's cold, the combined effect of Superior to the traditional convection heating.The electric conductive film is made from the special ink, metal carrier, as printed in pressing between the two insulation made of polyester film.Usually have a roof installed, floor installation, wall-mount installation form.

2 low-temperature electric radiation film to warm the main characteristics of heating system (convection heating system and compare)
2.1 for regional control, energy conservation

As installed in each room temperature, may need to adjust and maintain a constant temperature, not to use the room temperature can be reduced or closed, the real economy, energy conservation, tested using this method can be energy-saving 10 percent to 20 %, And heat transfer equipment will not be able to adjust with the outdoor temperature changes at room temperature, even the electric boiler centralized control of temperature, it is difficult to make room temperature uniform, in high-rise building, the system can eliminate the imbalance and the vertical and horizontal layered heating , The system overpressure, and other issues.

As the warm temperature-conditioning system has its unique advantages, when the office buildings, residential buildings or hotels, etc., during the day or at night when no one can lower the temperature on or off the system in order to achieve energy-saving purposes.Fujian Province has many tourist scenic areas, some only resort hotel in the tourist season, hotel occupancy rates during times of high occupancy rate is very low, using the system can significantly reduce operating costs, and other heating systems in the system part load operation, Closed some rooms can only be the end devices, and the entire system is still in the running as usual, can not really achieve economic operation.

2.2 increase comfort

Radiation to warm heating, indoor temperature distribution than convection heating, even more, heating the surface around the room temperature higher than the air temperature of about 3 ° C, while the average velocity of indoor also lower, due to surrounding temperature increase, a decrease of Cold radiation on the human body, and convection heating, air temperature over radiation temperature and comfort in the same conditions, human limbs and trunk of the temperature difference between 4-6 ° C, heating, this very small margin.Since radiation and the dual role of temperature, resulting in cooling the body with real heat, with the best comfort.

2.3 clean sanitation, no pollution

Warm while the system is running, no indoor hot air convection caused by floating dust, indoor air cleaner and useful health, and noise-free operation, Wu Qiwei, no emissions, more conducive to urban construction and environmental sustainability control .And convection heating, indoor air circulation, causing dry and dust into the air.

2.4 saving water

Traditional heating required for hot water cycle, electric film to warm the heating system will be directly converted into electricity for heat, no water, saving the valuable water resources,

2.5 long service life, not set up special maintenance, repair bodies

Electric heating to warm the membrane system and the life of the building with life, no activities of the components and fully enclosed, so no parts will be damaged, there is no room for cleaning or painting, there is no plumbing system running, running, drop , The leakage problem, such as headache, the need to maintain and manage personnel, thereby saving some of the funds.

3 low-temperature membrane radiation electric heating system to warm the heating system and other economic and technical comparison with the increase in global awareness of environmental protection, environmental protection, saving hard-renewable resources, to promote the use of electricity, natural gas, liquefied petroleum gas and other clean energy, Into the mainstream of contemporary social development, so in this article, we do not need to compare and coal-fired boiler.

4 Conclusion
4.1 determine heating, with the works of air-conditioning, heating system to consider reunification.

4.2 pair of smaller buildings, air-cooled heat pump systems for the first choice.

4.3 pairs of large and medium-sized construction and operation of the load quite a long time, the electric heating to warm the film as the preferred system.

4.4 pairs of some large hotels, often with laundry, meals, bathing, and other heating systems, often using oil-fired boiler heating system, heating heating be considered.

In short, the membrane electric heating to warm the system without basic maintenance, long life, reliable and safe operation of the construction is simple, comfortable indoor environment.Fujian Province than adequate power, especially in winter, some can not build in the boiler room of the building, senior residential villas, often no one's holiday tourism guesthouses and hotels and other commercial films is particularly suitable for electric heating system, but with this technology continues to Improvement and development of that area in Fujian Province will receive extensive promotion and application.
