Photovoltaic glass curtain wall to create a real green building
this is the world's first building integration demonstration building with large-area and multi angle application of photovoltaic cell modules, with a total installed capacity of 0. 3 MW -
this is a five-star hotel, and this is also a photovoltaic power station. It is called "powervalley Jinjiang International Hotel". However, in Baoding, where it is located and known as "China powervalley", people prefer to call it "five-star power station"
2 put down the drawing pen on the putter and enter the drawing preparation form (only when it needs to be painted). On January 16, the winter afternoon sunshine slanted on the wall of the 25 story "five-star power station". From a distance, its dark blue glass curtain wall with dark stripes looked like a cloak, showing the breath of modern rationality and making public its distinctive personality. When you look closer, the true face of the photovoltaic power station appears in front of you: "the dark blue glass draped on the walls, windows and roofs is not an ordinary glass curtain wall, but is composed of pieces of glass embedded with metal wires, which outline the glass into delicate, small rectangles of different shades. Yingli company staff who maintained here told that this piece of dark blue glass solar photovoltaic cell module formed a breathable and replaceable photovoltaic glass curtain wall outside the building. A visitor once joked, "Oh, the sun shading glass of this hotel is beautiful."
this gorgeous "sunshade glass" not only makes this hotel have a unique beautiful external wall in the world, but also makes it the world's first building integration demonstration building with large-area and multi angle application of photovoltaic cell modules. Originally, ordinary polysilicon photovoltaic modules are light tight. In order to ensure good lighting in the hotel room, Yingli company developed a new light transparent all glass module according to the characteristics of the hotel building, which is used to replace the traditional glass curtain wall. This new glass curtain wall not only has the function of the traditional curtain wall, but also can generate electricity. Replacing the traditional curtain wall widely used in ordinary buildings with photovoltaic glass curtain wall can not only save building materials, but also shade, save energy and sound insulation
from the hotel guest room, the photovoltaic glass curtain wall really has the function of sunshade. "The sunlight that can't be directly into the room is converted into direct current through the metal wire clamped in the glass," the waiter of the hotel said slightly mysteriously, pointing to the completely static metal wire. "Electricity is flowing inside. It will gather in the basement in a moment, and then enter the country's electricity from there."
follow the "flowing" solar circuit diagram to the control room on the bottom floor of the hotel. Here, the direct current from the photovoltaic glass curtain wall is converted into alternating current through the "inverter". The factors causing instability should be eliminated and then incorporated into the national power. As a result, the five-star hotel has a total installed capacity of 0. 3 megawatt green power station
"this hotel is a real green building, and it is also a landmark building of diangu square," Yuan Jinghua, deputy director of Baoding high tech Zone, told that in addition to this Jinjiang International Hotel, the "diangu square" in China also has a business conference center, a business club, a large underground parking lot, expert apartments, employee residences, etc. All buildings will be covered with photovoltaic glass cells, and renewable energy such as solar energy will be fully applied. Finally, diangu square will be built into a building with a total design capacity of 1. 5 MW photovoltaic power station. After calculation, this power station will generate 1.71 million kwh of green electricity every year, which can replace 684 tons of standard coal
