Abstract
The invention discloses an application of solar energy phase change thermal storage to a greenhouse. A gable wall, a rear wall, a fence wall, floor tiles and a ceiling skylight are included, heat-preservation layers arranged at the outer sides of the main wall bodies of the gable wall, the rear wall and the fence wall, and a phase change thermal storage layer is arranged at the inner sides of the main wall bodies and on the floor tiles. A thermal storage cover board capable of being opened is hinged to one side edge of the nightside of the ceiling skylight, and the lower surface of the thermal storage cover board is covered with the phase change thermal storage layer. According to the phase change thermal storage layer, a sizing agent is formed by mixing sodium acetate trihydrate, Portland cement, carboxymethyl cellulose, calcium chloride, coal ash and water, the inner side of each wall body and the lower surface of the thermal storage cover board are coated with the sizing agent of the mixture, and the sizing agent comprises, by weight, 45-50 parts of sodium acetate trihydrate, 1-2 parts of Portland cement, 1-3 parts of carboxymethyl cellulose, 0.5-3.5 parts of calcium chloride, and 45-50 parts of coal ash. According to the application of solar energy phase change thermal storage to the greenhouse, the natural solar energy is sufficiently used, production cost is saved, the cost of the greenhouse is lowered, and the environment pollution, caused by high energy consumption, to environment is avoided.
Description
Technical field
The present invention relates to solar energy phase transition heat accumulation technology, particularly relate to solar energy phase transition heat accumulation and apply at green house.
Background technology
Along with the growing tension of global energy situation, energy-conservation and environmental protection is subject to countries in the world and more and more payes attention to.The energy is the basis that the mankind depend on for existence, but because the supply and demand of the energy has stronger timeliness and spatiality, at green house due to greenhouse effect and the more high reason of intensity of solar radiation, one is higher for air themperature in daytime green house, need ventilation more, virtually wasted certain energy, and to the reduction of night along with outside air temperature, night in winter, need heated more again, along with energy shortage day by day, the lifting of heating cost, the bottleneck that has restricted hothouse production benefit and development speed is that energy consumption cost is too high always.Research and develop new greenhouse heat-storage heating technique, especially studying and how utilizing more fully clean reproducible solar energy is the key subject of greenhouse industry development.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of solar energy phase transition heat accumulation to apply at green house, effectively solves green house energy consumption cost too high, utilizes fully clean reproducible solar energy new forms of energy and saves the energy.
The technical scheme adopting is:
Solar energy phase transition heat accumulation is applied at green house, comprises gable, Hou Qiang, enclosure wall, floor tile and ceiling skylight, in the outside of the main wall body of gable, rear wall and enclosure wall, is provided with heat-insulation layer, at inner side, the floor tile of this main wall body, is provided with phase-transition heat-storage layer.The back one side in ceiling skylight can be opened accumulation of heat cover plate along being hinged with, and the lower surface that can open accumulation of heat cover plate is covered with phase-transition heat-storage layer.
Above-mentioned phase-transition heat-storage layer thickness is 3～6mm.
Above-mentioned phase-transition heat-storage layer, is mixed into slurry by Sodium acetate trihydrate, portland cement, carboxymethyl cellulose, calcium chloride, flyash and water and is coated in the inner side of each body of wall and the lower surface of accumulation of heat cover plate, matches well by weight as follows:
45～50 parts of Sodium acetate trihydrates, 1～2 part of portland cement, 1～3 part of carboxymethyl cellulose, 0.5～3.5 part, calcium chloride, 45～50 parts, flyash.
The present invention makes full use of solar energy natural energy source, has saved production cost, has reduced product price, the environmental pollution of having avoided high energy consumption to bring.
