Background technology
Human lives be unable to do without hot water, and we wash dish, cook, laundry, bathing, washing etc. all be unable to do without the demand of hot water, and the use of hot water has become human lives and improved the sign greatly with social progress.
The development of electric heater and gas heater, has become the inevitable choice of urbanization family, and also very swift and violent in the development of rural area solar water heater.But it is main that the development of certain hot water supply system also only limits to family oriented hot-water heating system.
As everyone knows, the development of tap water pipe network is to disperse water intaking water to develop into the process of concentrating water intaking to disperse water by well, gas distributing system development develops into gas distributing system centralizedly supply by the natural gas tank occupation mode of disperseing and disperses the mode of using, as a same reason, the development of hot-water heating system has not to be had to develop into the pattern that centralizedly supply disperses use, and how far the change of this hot water life style also has from us.
Solar energy is the abundantest, the most lasting and the most clean universally acknowledged regenerative resource.Utilizing solar energy to substitute fossil energy (coal, oil, natural gas), is the mankind, especially in China, adheres to important channel and the means of sustainable development, and more national industrial policies are advocated and helped.The development and utilization of China's solar energy, takes its place in the front ranks of the world at aspects such as technological innovation and industry sizes.2013, China's solar thermal utilization industry sales volume reached 6,600 ten thousand square metres (46200MWth), and recoverable amount reaches 31,000 ten thousand square metres (217000MWth), nearly 1,000 hundred million yuans of the output value.Today that the environment of depending on for existence the mankind is destroyed day by day, people more and more pay attention to research and use the solar energy source of sanitation and hygiene, and solar energy will become " basis of future source of energy structure ".
The photo-thermal industry of China has been passed through the development of two more than ten years.Solar heating engineering market has also experienced from rural area to city to concentrated process, solar energy industry is in the critical period of upgrading transition, solar thermal utilization has started from monomer user's solar water heater to solar heating and solar heating engineering development, urbanization process has highlighted the importance of solar heating engineering architecture-integral more, and hot water engineeringization is leading industrial market fast-developing.
Conventional solar hot water all using liquid especially water as conducting heat, thermal storage medium, there is defect and drawbacks such as " easily freeze winter, over-heating in summer, leakiness, perishable, the life-span is short ", particularly outstanding in the area of cold, lack of water, supply of electric power deficiency.And the area that these economic developments relatively lag behind exactly, natural environment is relatively severe is that solar energy resources is abundant, the area that heating and hot water supply requirement are large.
