2602.等效发光效率——发光器的发光效率标准化指数
[计算机、通信和其他电子设备制造业,水利、环境和公共设施管理业] [2015-07-15]
The luminous efficiency do make four impact factors confused such as existing of dissipated light,ability for transmission of lighting sources,distortion of visual effects and different values of power choosing during the luminous efficiency comparison under its current definition.In this paper,the equivalent luminous efficiency was introduced based on the discussion of these factors which maintains the form of current definition of luminous efficiency while it sets the equivalent coefficient to make test results comparable under different measurement conditions,so as to be clear when we compare and evaluate the properties of energy-saving and luminescence of luminaries.

2605.通过简单廉价的高级电源板减少办公室插头负载
[水利、环境和公共设施管理业] [2015-07-15]
In recent technology demonstrations, data from occupancy sensors tracking plug load reductions with occupancy have shown energy-saving potential for both business and nonbusiness hours. Also, dense panel-level sub-metering has been used to quantify whole-building receptacle circuit energy consumption, energy savings, and return on investment for the whole building. Receptacle-level metering has been used to show the plug load energy consumption of individual devices and workstations. This paper documents the process (and results) of applying advanced power strips with various control approaches.

2607.冷屋面措施能源消耗的初步分析
[水利、环境和公共设施管理业] [2015-07-15]
The spread of cool roofing has been more than prolific over the last decade. Driven by public demand and by government initiatives, cool roofing has been a recognized low cost method to reduce energy demand by reflecting sunlight away from structures and back into the atmosphere. By use of commonly available calculators, one can analyze the potential energy savings based on environmental conditions and construction practices.

2608.使用光还原法的聚四氟乙烯工业废水中全氟化碳的消除
[水利、环境和公共设施管理业] [2015-07-15]
Decomposition and defluorination of PFCs in wastewater by photo-induced hydrated electrons was well and firstly investigated in this paper.In this work the proposed method was tested to deal with PFCs containing wastewaters from a Teflon-manufacturing plant in Jiangsu Province, China.95.5％ of perfluorooctanoic acid (PFOA) was decomposed after 12 hours treatment and defluorination rate of PFCs could reach about 60％.PFCs were transformed into harmless fluoride, acetic acid and formic acid.It was suggested this system can efficiently decompose PFCs from fluorine chemical plant.In brief, this study demonstrates that the photo-reduction is a high efficient, energy-saving method which produced less-toxic products for PFCs removal, compared with activated carbon absorption and combustion.
