New Energy Saving and Reducing Technology of Solar Energy and Ground Source Heat Pump

Sunlight introduction technology

A device called “Sampap” system that utilizes solar energy for indoor lighting is a device that is truly healthy, green, energy-saving, and safe. The device is composed of a lighting mask, a waterproof device, a light guiding pipe with a light guide of 30 degrees or 50 degrees, a ceiling fixture, and a light diffusion device, and can effectively put it on a sunny or cloudy day or even on a rainy day. The outdoor natural light is introduced into the system through the daylighting hood. After specially manufactured light guide pipes are transmitted and reinforced, natural light is evenly radiated into the room through the diffusion device at the bottom of the system. According to this principle, the “Tongji Oriental Sunlight” lighting system has natural light illumination and no power costs; the lighting is not affected by the orientation and the opening of the windows; the system is fully enclosed to prevent the entry of dust and mosquitoes without cleaning. And maintenance; compared with the traditional roof lighting device can avoid the summer heat transfer and winter heat loss defects, can effectively reduce the cost of summer cooling and winter heating; good for health, natural light makes people comfortable; diffuse device soft light , No glare, no reflection on the display. The underground garage of the Beijing Olympic Stadium will use the “Tongji Oriental Sun Light” light pipe technology to collect natural light and provide natural light lighting for the underground garage duty room.

Solar photovoltaic technology

As a national science and technology demonstration project, the 100 kilowatt solar photovoltaic power station of 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 systems and architectural aesthetics. Monocrystalline silicon solar panels will be installed on the roof lighting window and the glass facade of the south facade. They are not only maintenance structures for building shade, daylighting, and rain protection, but also generate electricity with an average daily generating capacity of 212 kilowatts per hour. These devices provide 15,000 square meters of lighting power for underground garages, avoiding peaks in the power grid during the day. Photovoltaic modules are integrated with the majestic architectural appearance, which not only saves energy, but also is environmentally friendly. It shows the solar photovoltaic technology directly to the public.

Shanghai Xizang Nanlu Yuejiang Tunnel will use solar energy for the first time as an energy source. The tunnel is located in the Expo Park between the two bridges in Lupu and Nanpu. The tunnel is a two-way, four-lane road. The main line starts at the intersection of South Zhongshan Road and Zhongnan Road. It passes through the Huangpu River to the southeast of Binzhou Road, and is about 2.67 kilometers long. The Jiangzhong Tunnel is 1,170 meters long. A total of 250 square meters of solar photovoltaic panels were designed and installed on the top of the light transition section of the entrance and exit of the cross-river tunnel, utilizing daylight solar energy to store electricity and generate 40 kilowatts per hour, providing part of the power for tunnel lighting. It is reported that at present the relevant design is basically completed, and only 4 million yuan will be required to implement the funds.

Ground Source Heat Pump Technology

In the composition of the energy consumption of the underground street, the main two items are the power consumption of the air conditioning system and the lighting system. The energy consumption of the air-conditioning system varies with the seasons, and the lighting system does not change with the season in a year and is relatively stable. It can be seen that the energy-saving design of underground shopping centers should focus on reducing the energy consumption of air-conditioning and lighting systems.

The energy-saving air-conditioning cooling and heat sources used in underground space facilities include: water-source heat pump air-conditioning, ground-source heat pump, energy-storage air-conditioning (ice storage, water storage air-conditioning), cold, hot, and electric triple (CHP) equipment, including water-source heat pumps. The air conditioning system is a new type of energy-saving equipment that utilizes energy in the formation. Shallow geopotential energy is a form of energy conversion that absorbs solar radiation from the earth. It exists in a constant temperature zone in the soil and underground water within hundreds of meters below the surface, and is basically unaffected by the region and the climate. The temperature is relatively constant. It is both recoverable and renewable, and is an inexhaustible source of low-temperature energy (10°C to 25°C). In winter, the heat pump's circulating water pipe obtains the heat in the soil, heats the building by heating the heat pump, and at the same time transmits the building's cooling capacity to the earth, gradually reduces the temperature of the earth, and stores the cooling capacity for use in the summer. On the contrary, in summer, the heat pump's circulating water pipe obtains the amount of cooling in the earth, cools the building after cooling with a heat pump, and transfers the heat in the building to the earth to store heat for winter use.
