Description
Technical field
The present invention relates to field of solar energy utilization, especially relate to the hot-water making method and the isolated plant thereof of a kind of solar energy heating and electrical heating combination.
Background of invention
Solar energy enormous amount, the annual solar radiant energy that arrives earth surface are about 130,000,000,000,000 tons of mark coals, but be characterized in having dispersiveness, discontinuity and unstability.Although the total amount of the solar radiant energy of arrival earth surface is very big, energy-flux density is but very low.On average, summer, fine midday sun radiation intensity maximum projected earth surface 1m
2Solar radiation power on the area only is that have only half winter about 1kw, and the cloudy day has only about 1/5.Therefore want to obtain certain radiant power, just need the bigger swept area of accepting.So-called discontinuity and unstability are meant that natural conditions such as solar radiant energy is subjected to round the clock, season, geographic latitude, height above sea level limit, and stochastic factor such as fine, cloudy, cloud, rain.For eliminate these shortcomings, just the energy storage problem when solve adopting hot water to make to use time-sharing work system or can reach round-the-clock use by means of the auxiliary of other energy with hot water with regard to needs.Energy consumptions for building such as hot water making can be finished with the regenerative resource of low level fully, if adopt high-order electric energy to finish to be a kind of waste to energy resources.
Development solar water heater's key is to realize breaking through with combining of building, even residential customer can both relievedly use easily, replacing electrical heating or gas-fired water heater, and obtain environmental protection and energy saving and economy.The basic demand of its hot water apparatus design is: the hot water output temperature remains on more than 45 ℃ by the industry standard requirement is satisfied, and device band antifreezing function can annual all-weather use, and promptly guarantees to supply in 1 year 365 days 24 hours hot water more than 45 ℃.In addition, product also requirement can farthest be saved conventional energy resource, has reached solar energy as prior art and has accounted for 70%, the auxiliary heating of low ebb electricity accounts for 30% level, device clean and maintenance and easy to use, hot water separates with electric auxiliary heating element, uses no security incident hidden danger.
A large amount of uses of apparatus for heating water by solar energy do not destroy if must produce the image appearance of building with the design of integrally combining of building.If do not change the installment state afterwards of no any design, finally can have influence on a building group, even the architectural scene of entire city, a kind of new visual pollution caused, heat collector can satisfy perpendicular the putting of metope the high thermal efficiency output that possesses long-term stability down is installed, and also is the aspect of a key.
The auxiliary heating means of the supporting conventional energy resource of conventional device comprise combustion heat energy and electric energy, use in the electric energy and comprise modes such as electrical heating elements and heat pump, as everyone knows, utilize the peak valley electricity can obtain best grid balance effect, for society saves a large amount of energy resources, therefore, whether hot water apparatus has the function of utilizing the energy-conservation heating of peak valley electricity low-power, is the important indicator of weighing hot water apparatus energy savings resource characteristics.
In addition, use in the mode of the auxiliary heating of solar energy and heat pump electric energy, the basic skills of prior art is with the preheating of solar energy heating as road, back heat pump, and to improve the efficiency of heating surface of heat pump, therefore, device all is based on heat pump.The technical scheme that is adopted as the Chinese patent CN158066A " the accumulation energy type heat pump assembly of solar energy and air combined thermal source " that has announced can possess the function of utilizing solar energy and air combined thermal source to make hot water simultaneously, comprised the compressor condenser in the device, solar radiation convection current composite energy storage type heat exchanger etc., wherein, adopt the air entry of compressor to link to each other with the outlet of solar radiation convection current composite energy storage type heat exchanger, the exhaust outlet of compressor links to each other with the refrigerant inlet of condenser, can utilize the solar radiation convection recuperator to improve the efficient that heat pump turns round in the winter time like this, overcome the not high disadvantage of heat pump running efficiency in winter, also solved frosting in the winter problem of heat pump radiator and the problem that low temperature can not start down simultaneously.According to aforementioned apparatus for heating water by solar energy with reply the requirement of closing heating by cable and analyze, existing deficiency in this technical scheme is: solar irradiation was arranged when daytime, during the work of solar radiation convection recuperator, device is in the real-time working state all the time, though the power consumption of adopting heat pump is on average common electrically heated about 1/3rd, but taken the power load of peak period, therefore, must consume the electric energy of a large amount of peak period high positions, unfavorable for balance electrical network daily load, such device is in case promote the gap that will further widen between the electrical network peak valley, the waste of aggravation coal for power generation charcoal resource.In addition, the absorption solar radiation is installed,, must be kept contacting, therefore certainly lead to laying dust and be difficult to cleaning, influence the efficient that it absorbs solar radiation with air because radiator also is used for heat radiation simultaneously though its heat pump radiator can be used as perpendicular putting.
CN1131400C " adopt warm air conditioning hot with solar-air electric heating combined heat-pump system " has announced that another adopts solar energy and replies the heating technique scheme of closing by cable, it has by the complementary characteristic that realizes that heating, air-conditioning, hot water three function synthesizeds utilize of solar-air electric heating three energy, in the heat supplying loop that its heat pump constitutes, condensation heat release in the recirculated water evaporation/condensation is flowed to branch coiler and/or radiator, and adopted the method for the compound heating of solar heat pump electrical heating triplicity, can provide the hot water byproduct under the air-conditioning providing.In this technical scheme, solar energy heating and electrical heating elements all are the front ends of heat pump, purpose only limits to improve the air-conditioning delivery efficiency of heat pump, the making that its heat pump is provided with hot water there is no contribution, and the hot water that is produced can't satisfy the 365 days 24 hours hot water apparatus standard-requireds that supply water by hot water standard more than 45 ℃, arrived overcast and rainy or winter, also must rely on the real-time heating of electrical heating elements to realize the heating of air-conditioning and hot water, therefore, just can take the power load of peak period and consume a large amount of high-order electric energy, such device is in case promote the gap that will further widen equally between the electrical network peak valley, the waste of aggravation coal for power generation charcoal resource.
