Abstract
The utility model discloses a sunlight energy accumulation heating system used for a greenhouse. The energy accumulation heating system used for the greenhouse mainly comprises an energy accumulation module and a temperature control module. An energy accumulation material is placed in a sealed solar thermal collector, so that the energy accumulation material is enabled to fully accumulate heat of sunlight in day and carry out heat exchange of air in the greenhouse through a fan in a forced mode according to set temperature conditions in night, so that the optimum temperature conditions needed by growth of plants in the greenhouse are guaranteed, and the aims of reducing heating energy consumption and achieving high-quality and high-efficient production increase of crops are achieved.
Description
Technical field
The utility model relates to a kind of energy storage heating system for green house, have and vary with temperature the characteristic that melts heat-absorbing energy-accumulating, energy storage heating system according to the utility model gained, can be widely used in the larger environment temperature controls of diurnal temperature fluctuation such as green house, can extend green house crop cycle, save the heating energy consumption at night.
Background technology
China is positioned at 18 °～54 ° of the north latitude of the earth, and the annual radiant all quality of this regional sun is 335～1000kJ/cm
2, during year illumination, number is 1000～3000h, belongs to solar energy resources big country.And green house can take full advantage of the heat that solar energy provides, the suitable microclimate that is independent of under overall situation is provided for plant growth, have variation, anti-season, anti-region, overtimely make production, improve the advantage such as rural holding availability, be highly suitable for our such large agricultural country and promote.
Although green house is used widely throughout the country, the solar energy utilization ratio is not high.When daytime, solar radiation was strong, due to the impact of greenhouse effect, cause the interior temperature of green house higher, for reducing indoor air temperature, usually need ventilation, virtually caused the waste of the energy; And to night, because traditional structure of greenhouse is simple, heat storage performance and heat-insulating property are poor, and the heat shortage causes day and night temperature large, and plant frozen injury may occur severe patient.Therefore, when outside air temperature reduces, for guaranteeing the temperature condition of crops normal growth, need heating winter, conventional energy resource consumption is larger, and solar energy is not effectively utilized.
For improving the solar energy utilization ratio of green house, using energy storage material is an effectively selection, energy storage material has high latent heat of fusion, can keep the temperature-resistant of self in crystallization and fusion processes, the temperature buffer effect is played in absorption and release by heat: continuous storing heat higher than crystallization temperature the time, suppress temperature and rise, release heat lower than crystallization temperature the time delays the decline of temperature.
Although energy storage material can reduce temperature fluctuation by heat absorption and release, but this might not be the needed temperature environment of plant growth, in fact isoperibol does not have benefit to the growth of plant, should be controlled at 30～34 ℃ as muskmelon the highest thermophilic on daytime, nocturnal temperature can be controlled in 8～18 ℃, under such temperature action, the muskmelon growth environment temperature difference is large, be conducive to carry out photosynthesis daytime, be conducive to the accumulation of Assimilate evening, melon and fruit robust growth, high yield, sugariness are high, and the disease incidence is low.The minimum temperature that advantageously grow is just controlled in the effect of energy storage material gets final product, but not keeps an isoperibol.The in good time heat that provides carries out temperature control, could bring into play to greatest extent the effect of energy storage material heat of fusion.
The utility model overcomes energy storage material automatically with the shortcoming of environmental temperature decline release heat by Temperature Control System Design, can provide suitable temperature environment for plant growth is intelligentized, plays energy-saving and cost-reducing effect.
The utility model content
The utility model discloses a kind of energy storage heating system for green house, can make the stored heat of energy storage material require to discharge according to the plant growth temperature environment, saved heating energy consumption, extended the crop-planting cycle, promoted green house high-quality, high yield, increase income.
Technology contents of the present utility model is as follows:
Energy-storage module adopts inorganic energy storage material, mean temperature according to the winter greenhouse booth, take into account the heat accumulation efficient of energy storage material, the crystallization temperature of determining energy storage material is 26 ℃, both be conducive to heat storage on daytime at this temperature, can guarantee the heat exchange of 10 ℃ of left and right at night again, latent heat of fusion is greater than 270kJ/L.
Energy storage material is contained in the building enclosure of airtight warming plate formation, only sunny slope cover light transmission preferably film (as plastic foil, acrylic panel etc.) as solar energy heating face, energy-storage module is placed in the parados place of green house, make energy storage material collect to greatest extent the storage solar heat, when environmental temperature drops to certain design temperature, temperature control system starts blower fan, make Forced Air Convection in the greenhouse, carry out high efficiency heat exchange with energy-storage module, realize the greenhouse air heating.
Description of drawings
Fig. 1 has installed wall end view after the green house of energy storage heating system.
Fig. 2 is the front view of energy storage heating system.
Embodiment
The northern China green house can be constructed thick insulated wall to resist the invasion and attack of north wind at night in winter usually in the north side, greenhouse; the related energy storage heating system of the utility model is in the heat-insulating property that strengthens the greenhouse heat-insulating wall; rely on its support force to be provided with energy-storage module and temperature control modules, as depicted in figs. 1 and 2.
1 is the insulated wall of green house, and 2 is the insulation backboard of energy-storage module, and 6 is the printing opacity collecting plate of energy-storage module sunny slope, and 3 is energy storage material, and 4 are the supporting construction of energy storage heating system.The heat energy that sunshine produces is stored in 3 after through 6 transmissions, and due to 2 insulation effect, even extraneous (in the greenhouse other positions) temperature drops to the crystallization temperature of energy storage material below 26 ℃, the heat of its storage can not be released yet, the heat only import but no export in the most of the time by day in energy-storage module.
In Fig. 2,5 is axial flow blower, 7 is air intake, 8 is air outlet slit, temperature is lower than design temperature in the greenhouse, and as the plantation muskmelon, evening, minimum temperature can not be lower than 8 ℃, when greenhouse temperature during lower than 8 ℃, axial flow blower starts, and the air in the greenhouse is admitted to the heat accumulation module and carries out heat exchange, and store heat is released.
Again come temporarily when daytime, solar heat stores again, and so iterative cycles, go round and begin again, and realized the efficient utilization of solar energy, saved the heating cost.
The technical scheme of above-described embodiment is explanation as an example only, can not limit protection domain of the present utility model, if the equivalent transformation that the technical scheme of embodiment is made all belongs to the protection domain of the utility model claim.
