Description
Technical Field
A building solar heat utilization design, in particular to a building design combining a glass curtain wall with solar heat utilization.
Background
With the construction of more and more large buildings, glass curtain walls are widely applied in China. The traditional glass curtain wall is a peripheral protection system of a building, has the functions of building and structure and enables the building to achieve a more attractive effect. Although the existing glass curtain wall can achieve the effects of heat preservation and energy conservation to a certain degree, a great improvement space still exists. Nowadays, the energy-saving society is more and more commonly known by people due to the more urgent situation of energy sources. The design is based on the current situation, the existing technology is integrated and improved, and the glass curtain wall type building achieves the effects of more energy conservation and more environmental protection on the premise of keeping the existing advantages.
Although there are many studies on the application of new energy to buildings and various other energy-saving buildings, including solar buildings, there is no study on the combination of solar heat utilization technology and glass curtain walls. The current solar heat collection technology is mature day by day, and the utilization efficiency of solar energy is also improved gradually. Various performances of modern glass curtain walls are also continuously optimized. The research provides a novel solar heat utilization mode by combining other researches on the basis of the existing heat collection technology and glass curtain wall technology.
Disclosure of Invention
At present, most glass curtain walls adopt coated glass, the light transmittance of the coated glass can be controlled, the control capability of incident sunlight and energy of the glass is improved, and most glass curtain walls adopt double-layer structures and have good heat preservation and heat insulation performance, so that the good effect of reducing energy consumption is achieved. The heat-reflecting film coated glass is taken as an example, has excellent heat-reflecting performance, good light transmittance for incident light and one-way perspective, and is beneficial to indoor warmness in winter and coolness in summer and energy consumption reduction of buildings. These advantages have led to the widespread use of heat-reflective coated glass. As far as it is concerned, the heat reflective film coated glass blocks 67% of the solar energy, only 33% entering the room. Especially in winter, the glass curtain wall blocks the solar energy from entering, so that the heating energy consumption of the whole building is greatly increased.
The invention aims to overcome the defects of the prior art and provide a solar heat utilization design of a building, and the invention is to consider utilizing the blocked solar energy. The energy can be used for heating in winter, and can be used for other purposes in summer, such as adding an auxiliary electric heater to provide domestic hot water.
The building heating energy generally needs low-temperature heat energy of 60-70 ℃ for a system adopting a radiator form, and only needs low-temperature heat energy of 30-40 ℃ for a floor radiation heat exchange system. At present, the flat plate type heat collector can generally reach 50-70 ℃ in winter, the heat collection efficiency can reach about 50 percent, and the flat plate type heat collector is exactly matched with the energy grade required by floor radiant heating and can meet the requirements of heat collection and heating.

Detailed Description
At present, glass curtain walls are generally divided into full glass curtain walls, frame glass curtain walls and point-supported glass curtain walls. The frame type glass curtain wall is divided into a bright frame curtain wall, a dark frame curtain wall and a unit type curtain wall. The invention mainly aims at the exposed frame glass curtain wall which is most widely applied, and other types of glass curtain walls can achieve the same effect through proper improved design. The structure of the exposed frame glass curtain wall is generally that a glass panel is embedded in an aluminum frame.
The glass curtain wall is utilized to collect solar energy, and the condition is that the existing glass curtain wall is improved and designed to achieve the heat collection performance.
As shown in fig. 1, the glass curtain wall adopts a three-layer structure, from inside to outside, which is respectively ordinary glass, heat-absorbing glass and toughened glass. The inner side of the heat absorption glass is plated with a selective absorption film. The glass panel and the aluminum frame are sealed by silicone sealant. A heat insulation area is arranged between the common glass panel and the heat absorption glass panel, and a heat collection area is arranged between the heat absorption glass panel and the toughened glass panel. The aluminum frame parts at two sides of the heat collecting area are provided with air vents for respectively air inlet and air outlet, and pipelines designed in the aluminum frame are connected with the air vents.
In the glass curtain wall, the heat collecting modules form the whole heat collecting part, and as shown in fig. 2, the heat collecting modules are connected in series and then connected in parallel.
The above is a heat collecting part.
The whole design is a double-circulation system, and the double-circulation system is arranged between the solar heat collector and the heat storage water tank and between the heat storage water tank and a room geothermal pipeline. As shown in fig. 3.
The hot air in the heat collector and the water medium of the heat storage water tank exchange heat through the circulating pipeline, so that the absorbed solar energy is transferred to the heat storage water tank.
The circulation between the solar heat collector (glass curtain wall) and the heat storage water tank is constant temperature control type circulation, as shown in fig. 4, a temperature sensing probe is installed in the heat collector to measure the air temperature in the heat collector, and when the temperature in the heat collector reaches a control temperature, a control circuit starts an air pump to operate. The control temperature is set by considering, in order to avoid the frequent start of the air pump, the control temperature can be set to a temperature section, and when the temperature reaches the upper limit, the air pump starts to operate. When the temperature is reduced to the lower limit, the air pump stops running.
The heat storage water tank is directly connected with a geothermal pipeline of a room, and hot water in the heat storage water tank circularly flows in the geothermal pipeline of the room, so that the room is heated. The circulation between the heat storage water tank and the room geothermal pipeline is manually controlled by actual needs.
In consideration of the practical application condition of the heat collector, an auxiliary heat source is arranged on the heat storage water tank. The auxiliary heat source is a heat pump with high energy efficiency ratio.
Therefore, the combination of solar heat utilization and an auxiliary heat source can completely meet the actual heating requirement in winter. In summer, the heating demand is not needed, the geothermal pipelines in the room can be closed, the pipelines can be switched, and the hot water in the hot water storage tank can be used for other purposes.
