Sunlight import technology
A device called Sampap system, which uses solar energy for indoor lighting,
is a truly healthy, green, energy-saving and safe device. The device consists of
a lighting cover, a waterproof device, a 30-degree or 50-degree light guide bend
in the light guide pipe, a ceiling fixture and a light diffusion device. It can
effectively lighten the light on sunny, cloudy or even rainy days. Outdoor
natural light is introduced into the system through the lighting cover. After
being transmitted and strengthened by a specially made light guide pipe, the
natural light is evenly illuminated into the room through the diffusion device
at the bottom of the system. The Tongji Oriental Sunlight lighting system made
based on this principle has natural light illumination and no electricity cost;
the lighting is not affected by the orientation and whether the window is open
or not; the system is fully enclosed to prevent the entry of dust and
mosquitoes, and does not require cleaning and maintenance. ; Compared with
traditional roof lighting devices, it can avoid the defects of high temperature
in summer and heat loss in winter, and can effectively reduce the cost of
cooling in summer and heating in winter; it is good for health, and natural
light makes people comfortable; the diffusion device has soft light and is not
Produce glare and no reflection on the display. The underground garage of the
Beijing Olympic venues will use Tongji Oriental Solar Lighting Pipe Technology
to collect natural light and provide natural light for the duty room of the
underground garage.
Solar photovoltaic power generation technology
As a national science and technology demonstration project, the
100-kilowatt solar photovoltaic power station at the Beijing National Stadium is
one of the largest solar photovoltaic power stations in Beijing. In terms of
design, it focuses on the combination of solar power generation system and
architectural beauty. Monocrystalline silicon solar panels will be installed on
the roof lighting windows and the glass curtain wall of the south facade. They
are not only maintenance structures for building sunshade, lighting, and rain
protection, but they can also generate electricity, with an average daily power
generation of 212 kilowatts per hour. These devices provide 15,000 square meters
of lighting power for the underground garage, avoiding the peak power
consumption of the power grid during the day. The photovoltaic modules are
integrated with the majestic architectural appearance, which not only saves
energy but is also very environmentally friendly, intuitively demonstrating
solar photovoltaic utilization technology to the public.
The Shanghai Xizang South Road cross-river tunnel will use solar energy as
energy for the first time. The tunnel is located in the Expo Park between the
Lupu and Nanpu bridges. The tunnel is a two-way 4-lane tunnel. The main line
starts from the intersection of Zhongshan South Road, Tibet South Road, and
crosses the Huangpu River in the southeast direction to the Binzhou intersection
of Pudong South Road. The total length is about 2.67 kilometers, of which The
Jiangzhong Tunnel is 1,170 meters long. A total of 250 square meters of solar
photovoltaic panels are designed and installed on the top layer of the light
transition section at the entrance and exit of the cross-river tunnel. They use
sunlight during the day to store electricity and generate 40 kilowatts per hour
to provide part of the power for tunnel lighting. It is reported that the
relevant design is basically completed and is only waiting for the funding of 4
million yuan to be implemented.
Ground source heat pump technology
Among the components of energy consumption in underground streets, the two
main items are the electricity consumption of air-conditioning systems and
lighting systems. The energy consumption of the air conditioning system changes
with the seasons, while the lighting system does not change with the seasons
throughout the year and is relatively stable. It can be seen that the
energy-saving design of underground streets should focus on reducing the energy
consumption of air conditioning and lighting systems.
At present, the energy-saving air-conditioning cold and heat source
equipment used in underground space facilities include: water source heat pump
air conditioners, ground source heat pumps, energy storage air conditioners (ice
cold storage, water cold storage air conditioners), cold, heat and electricity
combined power supply (CHP) equipment, among which water source heat pumps The
air conditioning system is a new type of energy-saving equipment that utilizes
energy in the ground. Shallow ground energy is the energy conversion form of the
earth absorbing solar radiation. It exists in the constant temperature zone in
soil and groundwater within hundreds of meters below the surface. It is
basically not affected by region and climate, and the temperature is relatively
constant. It is both recoverable and renewable, and is an inexhaustible
low-temperature energy source (10℃~25℃). In winter, the circulating water pipe
of the heat pump obtains heat from the soil and heats the building after being
heated by the heat pump. At the same time, it transfers the cold energy of the
building to the earth, gradually reducing the temperature of the earth, and
storing the cold energy for use in summer. On the contrary, in summer, the
circulating water pipe of the heat pump obtains the cold energy from the earth,
cools the building after being refrigerated by the heat pump, and at the same
time transfers the heat in the building to the earth, storing the heat for use
in winter.
