Powervalley International Hotel

China's first photovoltaic building: diangu International Hotel

The design concept of "electric Valley" is to define it as "the fashion of metal and glass". The whole design fully absorbs the modern design elements of international fashion and high quality, and integrates building energy-saving solar photovoltaic glass curtain wall into the overall design. The advantages of solar glass curtain wall are: shading, environmental protection, energy saving, sound insulation, beautifying the building, good light transmittance, generating electricity, reducing work and management costs, solid structure, etc. The whole building uses sewage source heat pump system for heating, cooling and domestic hot water, which improves the utilization efficiency of renewable energy. The application of solar grid connected power generation technology, BIPV technology and sewage source heat pump technology will comprehensively enhance the overall image of "China Power Valley". A CBD with green, environmental protection, original ecology and humanization will be displayed in front of the world. The photovoltaic grid connection project of diangu international hotel is not only a perfect combination of photovoltaic and building integration, but also integrates the generated power into the local power grid, becoming the first project to realize photovoltaic grid connection in Hebei.

In this regard, the main leaders of Hebei provincial Party committee, Hebei provincial government, Baoding Municipal Party committee and Baoding Municipal government visited diangu international hotel for many times to guide the photovoltaic grid connection project; the national development and Reform Commission, Hebei Provincial Development and Reform Commission, Baoding development and Reform Commission and other relevant functional departments gave great support to the photovoltaic grid connection project of diangu International Hotel, strictly in accordance with the renewable energy law and other relevant laws and regulations The efficient approval of the project has provided guidance for the smooth approval of the project; provincial and municipal power supply companies and other departments have given great help in the feasibility of grid connection and the implementation of grid connection technology, so that the project can quickly reach the grid access conditions and smoothly realize grid connection.

At the same time, Yingli independently developed the photovoltaic power generation data control system, and built the system control room on the first floor of the hotel, which makes the management and maintenance of the hotel after grid connection very simple and efficient. It goes hand in hand with the hotel's service and management system without any impact. This system can easily monitor the use of each panel. All the solar panels in the hotel have realized modular installation and maintenance, because the design life of the solar panel is 25 years. If one of the panels fails, it is convenient to replace it without affecting the whole system. According to Yingli's experience in the design, construction and maintenance of the grid connection project, the maintenance cost of the grid connection project is very small, and the solar panel has few failures. At the same time, the system can record the power generation of the hotel grid connection project in real time. The LCD in the hotel hall records the power generation, total power generation, solar irradiance, wind speed and other weather parameters of the solar power generation system at any time. It makes us feel that solar power is everywhere. As the first five-star hotel in China to install photovoltaic glass curtain wall to realize grid connected power generation, its construction not only saves land, but also saves storage space and operation cost of battery replacement. Its successful grid connection breaks through many difficulties in the installation and grid connection of photovoltaic and building integration projects, and provides important practice for the compilation and formulation of BIPV regulations and BIPV operation policies.

Power generation Hotel

From a distance, the electric Valley Hotel is no different from other star hotels, especially the dark blue glass curtain wall covered with the outer wall of the hotel is shining in the sunlight. Only when you get closer can you see the solar panels embedded in the glass curtain wall. Zhao Jianping, manager of Application System Department of Yingli group, the construction unit of the hotel, said with pride: "this hotel is the first time in China to apply breathing solar glass curtain wall, which can generate electricity when there is light. In fact, it is a small power station that can output electricity." According to the introduction, China's solar photovoltaic utilization and building integration is still in its infancy, and diangu hotel is absolutely the first to "eat crabs" by using solar power. It is understood that more than 3300 pieces of solar glass curtain walls have been installed in 9 areas, including the South and West facades of the 26 storey Hotel, and the canopy above the gate to protect guests from the wind and rain. As long as there is light, the hotel is a small power station, and its installation capacity can reach 300 kW, because considering the beautiful appearance, all the solar glass curtain walls can not be completely exposed to light, even if such as Therefore, its annual power generation can reach 200000 kwh, which can fully meet the lighting needs of the hotel itself, and can also be connected to the grid for power generation. It is a model project of domestic photovoltaic grid connected power generation.

"We are very particular about the installation of glass curtain walls." At the scene, engineers of Yingli group told reporters that when the temperature of the solar power system's battery module is higher than 25 ℃, the power of the battery module will drop. Therefore, technicians set a large number of shutters at the bottom and top of the curtain wall to cool the curtain wall through the opposite flow of air, which is called "breathing solar glass curtain wall".

Reuse of waste water

As an "environmental protection building", another highlight that diangu hotel has to mention is wastewater reuse. "There is something else under the northeast corner of the hotel hall." The Engineer in charge of the communication, air conditioning, water supply and drainage, fire fighting and other projects of the whole building told the reporter. It turns out that the heating and cooling of the whole building all depend on the reclaimed water discharged from the sewage treatment plant, which is stored in the super large fire pool under the northeast corner of the hall. Insiders told reporters that not far from the west of the building is Baoding Lugang Sewage treatment plant, where the wastewater after primary treatment (that is, what we usually call reclaimed water) will be injected into a fire pool with a volume of 1200 cubic meters through an 800 mm diameter water pipe. Through the compressor, the temperature of reclaimed water is raised from 25 ℃ to 30 ℃ in summer to extract the cooling capacity of water; in winter, the temperature of reclaimed water is reduced from 16 ℃ to 10 ℃ to extract the heat of water. In this way, a large number of cold and heat sources can be extracted from the water to supply cooling and heating for the building, and the reclaimed water after extraction of "energy" can be used for hotel bathing, flushing, car washing, etc. in other words, in addition to drinking, the reclaimed water can be used safely in all links of the hotel that need water. Due to the use of new technology, the energy efficiency ratio of reclaimed water is very high. According to reports, the cost of reclaimed water is far lower than that of surface water, and the use of water source heat pump will not burn mineral energy, reducing harmful gas pollution. Due to the use of water source heat exchange, the heat exchange efficiency is high, the condensation temperature is greatly reduced, and the energy saving is 40% - 60% compared with the general air conditioning equipment.

Baoding business card

"China Power Valley" has become one of the most popular business cards in Baoding today: it has formed six industrial systems: solar photovoltaic power generation, wind power generation equipment, power transmission and transformation equipment, energy storage materials, power electronics and power automation equipment, power transmission and transformation equipment and high-efficiency energy-saving equipment. At the 2008 "China Electricity Valley · low carbon Baoding" (Shenzhen) promotion conference held on October 12, the mayor of Baoding said that while speeding up the process of new urbanization and industrialization, we should always maintain low energy consumption and low carbon dioxide emissions, and strive to open up a "green channel" between industrial civilization and ecological civilization, so as to create an energy-saving, environmental friendly, green and low-carbon ecological civilization To support the construction of "China Power Valley · low carbon Baoding" is to implement the scientific outlook on development, save energy and protect the environment. As the first solar photovoltaic building in China, diangu hotel has become a demonstration base for building integration of solar power generation in China. Ma Xuelu, former director of Baoding high tech Zone Management Committee, said that this building has made breakthroughs in many aspects. It not only uses solar energy for the purpose of utilizing solar energy, but also combines with architectural decoration. This is the first time in the world.

It is understood that diangu international hotel is only the first phase of Baoding "diangu square - 1.5MW solar grid connected power generation system and sewage source heat pump renewable energy demonstration project", and the second and third phases of the project, including the development of clubs and surrounding communities, will be carried out later. After the completion of the whole project, a 1.5 MW photovoltaic grid connected power generation system will be built, with an annual power generation of 1.71 million kwh, which can replace 684 tons of standard coal.

Optoelectronic integration

As the first solar photovoltaic building in China, the completion and use of diangu international hotel has a very important reference significance in our province and even in our country. " Solar photovoltaic building is in line with the theme and trend of energy saving and emission reduction, and represents a development direction of future buildings. As required by the 17th National Congress of the Communist Party of China, we should "build a resource-saving and environment-friendly society" and "implement it to every unit and family". Informed sources told reporters that our province is located in the north, sunshine is very abundant, but such sufficient sunlight resources, and did not cause people's attention.

The rise of diangu hotel is bound to open a new page in the application of new energy in China. The internal structure of the electric Valley is very beautiful. There is a coffee shop on the first floor, with water curtain and European style rotation
