Solar energy, wind energy and air energy comprehensive hot water supply system and its implementation
Technical field
The present invention relates to hot water provisioning technique field, combine the advantage of solar energy, wind energy and air ability, specifically propose a kind of solar energy, wind energy and air energy comprehensive hot water supply system and its implementation.
Background technology
Along with the development of society, the restraining factors that the energy becomes social progress just constantly penetrate into every field.The continuous minimizing of traditional energy; Under the background that energy shortage and energy prices rise steadily; Country pursues the strategy of sustainable development energetically, advances renewable energy technologies and product to be widely applied in commercial production and the daily life, also receives broad masses of the people's support simultaneously.For this reason, people turn one's attention to the exploitation of new forms of energy, and the renewal, particularly eco-friendly power source of technology, like nuclear energy, whose ability, wind energy and solar energy etc.; Because above-mentioned eco-friendly power source has that cost is low, the technical sophistication degree is little, is not subject to advantages such as environmental limitations, so above-mentioned eco-friendly power source more and more comes into one's own and popularize.
Solar energy is a kind of as regenerative resource, more and more receives people's favor, and solar water has also received widely as mature technique comparatively and having applied.Because weather is complicated and changeable; And day alternates with night; So rely on solar energy to obtain heat energy to produce the solar water heater of hot water; Generally all need combine electric heater heating complementary type,, produce hot water to satisfy actual hot water supply needs through auxiliary electric heater to satisfy under the not enough situation of illumination.But auxiliary electric heater power consumption is high, occurs danger such as electric leakage, dry combustion method during its work easily.And; The complementary solar water heater of electrical heating at present mainly adopts the FCL mode of heating; Because storage tank is integrated design, just can supply water so must make whole box water all satisfy the demand data that the user sets, therefore be difficult to accomplish whenever and wherever possible, go out fast hot water.
Than above-mentioned solar water heater; When can fundamentally having eliminated electric heater electric leakage, dry combustion method and gas water heater working, air-source water heater produces potential safety hazards such as pernicious gas; Overcome the overcast and rainy or shortcoming such as can not work night of solar water heater; Have energy-efficient, safety and environmental protection, round-the-clock running, plurality of advantages such as easy to use; The strategy and policy that meet China's energy, society, environment sustainable development, thereby will become the most competitive water heater product of new generation of China.But air-source water heater is with respect to solar energy, its use be the economizing type energy, power consumption is bigger, the air compressor energy consumption that is mainly reflected in wherein is bigger, and, also need to introduce separately its operation of commercial power supply.
Wind energy also is a kind of renewable, pollution-free and energy that reserves are huge.Because China has abundant wind resource, under national policy is helped, obtained fast development and applied in recent years.But because geographical environment, meteorological complicated and changeable, wind-driven generator must just can obtain operation when wind-force satisfies service condition.
In sum, prior solar water heater, wind-driven generator all receive the influence of natural conditions, and solar water heater need be aided with electric heater usually and satisfies hot water supply needs even; And air-source water heater power consumption is big, needs to introduce its operation of commercial power supply, and the hot water supply is difficult to guarantee continuation.
Along with global warming and energy crisis, each state reduces carbon dioxide isothermal chamber gas purging, the earth of protecting us to depend on for existence all in the development and utilization that steps up the regenerative resource and the economizing type energy as far as possible.Although existing solar energy, wind energy, air can receive above-mentioned such-and-such limitation; But solar energy, wind energy, air can be to have complementarity; If the advantage of ability integrated solar, wind energy, air ability technology; Not only will solve the persistent problem of hot water supply, and also can utilize various renewable resources, the economizing type energy more efficiently, further realize the target of energy-conserving and environment-protective, economy, sustainable development.
