Some large public buildings in Beijing waste energy, and corridor lighting uses ten thousand lights
The inspection of some large-scale public buildings in Beijing by the seven energy-saving monitoring agencies in Beijing found that commercial buildings and office buildings are wasteful in lighting. Generally, in order to pursue the decoration and decoration effects, energy conservation is neglected, and the installation density of lighting fixtures is very high. , high power consumption.
The inspection found that some buildings use only tens of thousands of lamps in corridor lighting. If the number of lamps is reduced by half, the building will save 600,000 kilowatt hours and save nearly 8%. Some hotels and restaurants are still using products that have been eliminated by the state. For example, some of the inspected units are still using the S7-type transformers that have been eliminated. Many refrigeration units do not have a variable frequency device, which causes a large waste when operating at low loads. Zhu Kewei of Beijing Energy Conservation Monitoring Center said that the frequency conversion related technology is very mature. It should be said that it is not difficult to install an inverter device.
In view of the contradiction between high-end office buildings, commercial buildings, hotels and the pursuit of decoration and decoration effects and energy conservation, inspectors suggest that some new technology devices can be used to solve these problems to some extent, such as installing dimming lights for incandescent lamps and fluorescent lamps to reduce illumination. Can guarantee a certain decorative effect, and can reach about 30% of the power saving. If you are uneasy with the dimming system, you should use energy-saving lamps.
