Description

Control system for construction process of prefabricated building

Technical Field

The invention belongs to the technical field of solar energy, and particularly relates to a solar air-conditioning type building wall and a system thereof.

Background

With the continuous development of economy and the large consumption of energy sources, energy conservation becomes a global concern, the utilization of renewable energy sources such as solar energy, wind energy, geothermal energy and the like, industrial waste heat and waste heat becomes a key point for research and development of various countries, however, the energy sources have the characteristics of discontinuity and instability, and therefore, the research of an energy storage technology is particularly important. The heat storage technology is one of energy storage technologies, and an important ring in the heat storage technology is the design of a phase change heat storage heat exchanger. The common phase-change heat storage type heat exchanger is formed by sleeving two pipes together, and cold fluid and hot fluid respectively flow through an inner pipe and an outer pipe. The phase change heat storage material is packaged in the phase change heat storage unit with a certain shape and applied to the heat storage box, so that the occupied area of the conventional heat storage box can be reduced, and the defect of discontinuous utilization of waste heat, waste heat and solar energy can be overcome. The flat plate type heat exchanger is a heat exchanger with the highest heat exchange efficiency in various heat exchangers at present, and has the advantages of small occupied space and convenience in mounting and dismounting. The high-pressure resistant staggered circulation structure of the plate heat exchanger is formed by combining concave-convex lines between two adjacent plates in a vacuum welding mode, and the staggered circulation structure enables cold and hot fluid in the plate heat exchanger to generate strong turbulence to achieve a high heat exchange effect.

Solar energy is inexhaustible clean energy and has huge resource amount, and the total amount of solar radiation energy collected on the surface of the earth every year is 1 multiplied by 10¹⁸kW.h, which is ten thousand times of the total energy consumed in the world year. The utilization of solar energy has been used as an important item for the development of new energy in all countries of the world. However, the solar radiation has a small energy density (about one kilowatt per square meter) and is discontinuous, which brings certain difficulties for large-scale exploitation and utilization. Therefore, in order to widely use solar energy, not only the technical problems should be solved, but also it is necessary to be economically competitive with conventional energy sources.

At present, buildings, industries and traffic become three major industries for energy use, and the energy-saving potential of the building industry is the greatest. The building energy consumption in China accounts for more than 27% of all energy consumption, and the building energy consumption is increased at a speed of 1 percent per year. In the energy consumption of buildings, the energy consumption of the heating air conditioner is the largest and accounts for more than 6 percent of the whole proportion. In global energy consumption, 45 percent of energy is used for meeting the requirements of heat removal, refrigeration, lighting and the like of buildings, and 5 percent of energy is used for the building process of the buildings, so that the energy consumption of the buildings is reduced, the energy consumption of the whole world is reduced, and the consolidation of the whole ecological system is favorably maintained. Under the environment of high-speed and stable development of economy in China, according to continuous improvement of living standard of people and rapid development of urbanization, building energy consumption and renewable energy utilization are urgent problems to be solved in the field of construction, and along with the improvement of the requirement of China on building energy-saving standard, low-energy-consumption buildings become the trend of future development. The development of a solar building integration technology and the improvement of the proportion of renewable energy sources such as solar energy and the like in building energy consumption are important means for realizing social sustainable development in the aims of energy conservation and emission reduction at the present stage. Energy-saving work in China starts late compared with developed countries, energy waste is very serious, and for example, building heating in China consumes heat: the outer wall is 4-5 times of developed countries with similar climatic conditions, the roof is 2.5-5.5 times, and the outer window is 1.5-2.2 times; the air permeability of the door and window is 3-6 times, and the total energy consumption is 3-4 times. In order to reduce energy consumption, the utilization of clean energy sources such as solar photovoltaic photo-thermal energy, wind power generation, tidal power generation and the like is gradually popularized in China at present, and some incentive policies are formulated.

The solar building integration technology is the development direction of the solar technology in the future, and refers to the overall design of bringing the utilization of solar energy into the environment, integrating the building, the technology and the aesthetics into a whole, and the solar facilities become a part of the building and are organically combined with each other, so that the investment can be saved, the integral aesthetic property of the building is not damaged, and the integration problem of the facilities and the building can be utilized to the maximum extent. The application of the solar building integration technology in heating can further reduce the building energy consumption. However, in the current practical engineering application, on one hand, the beauty of a building cannot be fully ensured, and meanwhile, the space occupancy rate of a wall body is possibly overlarge, so that the assembly efficiency of the building structure is reduced, and on the other hand, the problem of low solar heat efficiency utilization rate exists.

For the above analysis, the following technical problems exist in the prior art: the integrated building wall has low solar energy utilization efficiency, the space occupancy rate of the wall may be too large, and the assembly efficiency of the building structure is reduced, so that improvement is needed.

In the designed center diffusion type flat tube, fluid enters a cavity of the flat tube from an inlet of a center area of the upper cover, passes through the bottom plate flow guide structure, gradually flows to the periphery of the cavity of the flat tube from the center inlet area, carries out convection heat exchange with the surfaces of flow channels (including column ribs) in the flowing process, and finally flows out from outlets on two sides of the flat tube after being mixed at a position connected with the heat exchange area, thereby carrying out heat exchange.

Compared with the traditional heat collecting tube plate, the center diffusion type flat tube changes the flow mode of fluid in a single inlet and single outlet mode, and replaces the single inlet and double outlet mode, so that in the design, outlets are processed on two sides of the flat tube, and the temperature uniformity of the heat flow surface of the flat tube can be effectively improved.

Further, the diversion structure, actually be some risers, can be regarded as the long straight type fin of bigger size, for reducing the flow resistance, to the fillet is handled to the diversion structure. Fluid flows in from the upper cover of the central diffusion type flat tube, passes through the flow guide structure and gradually flows to corner areas, so that dead flowing areas of the four corner areas of the flat tube can be avoided.

risers

42 and 43, after the air passes through the riser 43, the air flowing out from the horizontal direction is divided at the risers 44 on the left and right sides, the air flowing out from the vertical direction is divided at the inner wall of the upper cover, and after the air passes through the area of the column rib 502, the air flows to the corner areas of the four outermost peripheries of the flat tube, and the flow dead zone is effectively reduced. The air finally converges outside the right and left risers 44, respectively, and then exits the flat tubes through the two

upper cover outlets
