Description
Technical field
The present invention relates to a kind of solar facilities, but particularly relate to a kind of large tracts of land, low-cost absorb, transhipment, the greenhouse that stores, discharge solar energy hold/heat-releasing apparatus with solar energy.
Background technology
Solar energy is a kind of inexhaustible, nexhaustible eco-friendly power source.Since the seventies in last century, the finiteness of supplying with in view of the fossil energy of routine and the increase of environmental protection pressure, many countries have started the upsurge of development and use solar energy in the world, aspect civilian, solar water heater is popularized, and main product has flat type solar heat collector, glass vacuum tube type solar thermal collector etc.In recent years, the photovoltaic product also was the gesture of " blowout ".
Also having some problems yet effectively utilize at present solar energy, mainly is that the efficient of collection, conversion and storage is not high, especially at agricultural production, fully, efficiently utilizes solar energy to also have very large development space.
The population report of delivering according to the United Nations estimates, to the year two thousand fifty population in the world will reach 9,300,000,000, if rely on traditional tillage method that depend on sky to receive, present in the world all arable land almost operates at full capacity, just supports reluctantly more than 60 hundred million present populations.So must seek a basic solution." warmhouse booth " can stride the crop culture in season at Limited Land, reaches the purposes such as high yield, excellent product, is the important component part of modern agricultural technology, has been subject to the great attention of national governments and each large scientific research institution.
Heliogreenhouse is the abbreviation of energy saving sunlight greenhouse, claims again brooder, is the exclusive a kind of greenhouse of the northern area of China.Be a kind of in the indoor greenhouse that does not heat, even in the coldest season, also only rely on sunshine to keep indoor certain temperature levels, to satisfy the needs of some class vegetable crop growth.Have the advantages that investment/cost of use is low, operational effect is good, be widely used.
Yet existing heliogreenhouse is also found some problems in actual use: daytime is because illumination condition is good, the noon temperature of shed is high, need window and ventilate to keep suitable temperature, the shortage of heat that seems when fast and nocturnal temperature descends, especially all the more so to some remunerative crops.
If there is not supplementary energy, heliogreenhouse can only be planted the crops of some low values, and growth cycle is long.For reaching the purpose of high yield, high added value, common way is to adopt supplementary energy night.Present stage, supplementary energy was mainly fossil fuel, and its power consumption is high, pollution is large, has restricted it and has further developed.
For addressing this problem, patent documentation CN1415923A provides a kind of soil thermal storage formula solar heat pump heating system and heat supply method.But have following deficiency: 1, solar thermal collector is the normal domestic solar water heater, and large tracts of land is used, and cost is high; 2, soil thermal storage, underground need are laid a large amount of heat-transfer pipes and are increased heat-pump apparatus, have increased equally the initial cost of facility; 3, soil hold/heat release is slow, efficient is low; Although 4, heat-pump apparatus efficient is higher, use electric energy to drive, increased operating cost.
In recent years, there is the researcher in the heliogreenhouse back wall, to survey suspension bilayer film (outer is that light-transmissive film, internal layer are absorption film, middle water flowing) and makes easy solar thermal collector, utilize water to hold/heat release.Although this mode cost is low, also has following deficiency: 1, the plastic sheeting heat conductivility is poor, hold/exothermal efficiency is low; 2, water flowing between double-layer films can produce water smoke and be attached to the light-transmissive film inboard when water is heated, seriously reduced light transmittance; 3, plastic sheeting easily aging and position easily scratches generally near passage, and service life is short; 4, need site operation, the cycle is long, labour cost is high, quality can't guarantee.
