2631.RTU挑战单元的部分负荷性能表征和节能潜力：大金反抗
[水利、环境和公共设施管理业] [2015-07-15]
This report documents the development of part-load performance curves and there use with the EnergyPlus simulation tool to estimate the potential savings from the use of Rebel units compared to other standard options. The conventional direct-expansion cooling model in EnergyPlus and its performance curve equations are not appropriate to use to capture the Rebels performance; therefore, performance curves suitable for the Rebel unit were developed. The data for the performance curves were collected through a series of laboratory tests. A detailed Energy Plus model was developed for a prototypical big-box retail store. The model used the new performance curves along with detailed energy management control code to estimate the energy consumption of the prototypical big-box retail store in three locations (Houston, Log Angeles and Chicago). The energy consumption by the big-box store was then compared to a store that used three different reference units.

2632.基于低碳经济的甘肃省旅游业能源消耗与CO2排放量的粗略估计
[水利、环境和公共设施管理业] [2015-07-15]
This article selects GanSu Province, the weak ecological environment, as the research object.In accordance with the documents research and mathematical statistics, and the "bottom-up" study method., we made an research on energy consumption and the CO2 emission of GanSu province from the tourism travel , tourism accommodation, and tourism activities, respectively.From the result, GanSu's tourism with low-carbon and energy-saving characteristics, accounting for 0.45％ energy consumptions and 0.86％ CO2 emission in that of the GanSu's tourism.It shows that tourism fits in with the requirements of low-carbon tourism development.However, one of the most important factor in the tourism energy consumption and the CO2 emission is the tourism transportation, accounting for 68.83％ energy consumptions and 65.96％ CO2 emission in that of tourism respectively, which should be focus on as the key link in low-carbon tourism development.

2633.办公楼地源热泵应用的初步筛查工具研究
[水利、环境和公共设施管理业] [2015-07-15]
The current practice for evaluating the payback period for a GSHP application can be time consuming and expensive owing to the large number of inputs required by simulations and the complexity of the simulations. It is highly desirable to have a tool that can estimate the payback period with reasonable accuracy but minimal expenditure of both time and money. An approach to simplifying the evaluation effort is to identify the key parameters that most significantly affect the payback period of GSHP applications. Through a comprehensive parametric study, key parameters are identified that, within a typical range of variations, can make more than a 30% difference in the payback period for implementing a typical GSHP system in typical medium-size office buildings.

2634.高层建筑的串并联结合恒压供水管道设计
[水利、环境和公共设施管理业] [2015-07-15]
The existing parallel type pressurized water supply pipeline of high-rise buildings has been improved to build energy-saving high-rise building water supply systems.Series-parallel combined constant pressure water supply pipeline is designed.Antipollution high water tank is reasonably installed above the middle area of the building to supply water for the middle area high water tank and supply pressurized water by water pumps for high-rise district.And PLC control system is designed to control the work efficiency of the water pumps according to the sensor feedback information.Verified by calculation and simulation,series-parallel combined constant pressure water supply pipeline is better than parallel water supply pipes in saving the energy which is about the middle-Hybrid phase consumption of the latter.PLC control is simulated and the results show that PLC can effectively control the water supply system to ensure stable water pressure so as to save energy.

2635.佛罗里达当地政府项目改造的最佳实践应用
[水利、环境和公共设施管理业] [2015-07-15]
The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annual energy savings of 15-30% and higher. This report describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the 'current best practices.' A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market. Our new local government partner, the City of Melbourne, implemented the best practices in a community-scale renovation program that included ten homes in 2012.

2636.在严峻的环境中使用地理信息系统评估能源倡议
[信息传输、软件和信息技术服务业,水利、环境和公共设施管理业] [2015-07-15]
This research examined the energy savings potential of improving the thermal properties of expeditionary shelters, and then evaluated these measures using a fully burdened cost savings technique. Geographic Information Systems, Radiant Time Series cooling load analysis, and fully burdened concepts were applied to develop a model that analyzes the economic effectiveness of various shelter improvements in any climate and location in the world. Specifically, solar flies developed through Solar Integrated Power Shelter System (SIPSS) program for installation on fabric shelters were examined. The model was validated against test data provided by the SIPSS program, and then it was applied to two case studies. Results indicated that the energy savings in transportation associated with point-of-use energy reduction initiatives can represent a substantial portion of the overall fuels savings, which validates the idea that cost savings should be evaluated on a fully-burdened basis.

2637.上海居住建筑的外窗固定遮阳的能源消耗和效率的效果分析
[水利、环境和公共设施管理业] [2015-07-15]
The building energy consumption simulation software DeST is used to analyze the effects of fixed shading over external window on energy consumption and efficiency, on the base of a residential building in Shanghai.The simulation results show that the fixed shading over south window has little effect on the overall energy saving of residential building.For east and west external window, if window area is not very large and its shading performance is better, the effect of fixed shading installation on energy saving is not obvious.On the contrary, if its area is large and its shading performance is ordinary, the effect is remarkable.Furthermore, when room ventilation capacity is poor, the effect of energy saving by fixed shading installation is more prominent.

2640.干湿循环对三峡支流消落带沉积物中可转化态氮及其形态分布的影响
[水利、环境和公共设施管理业] [2015-07-04]
水体富营养化的形成与沉积物中氮素的“源-汇”关系密切，本研究选取三峡典型支流澎溪河消落带上、中、下这3个水文断面，160M和170M两个水位高程，0~20、20~40、40~60、60~80、80~100cm共5个深度的沉积物样品，通过研究其总可转化态氮（TF-N）与各形态可转化态氮含量及分布特征，旨在揭示周期性水位变化对消落带沉积物氮释放的影响。结果表明，澎溪河消落带沉积物总氮含量在313.02~3255.53mg﹒kg-1之间，空间分布上呈上站位（渠口）>中站位（高阳）>下站位（双江）的趋势；总可转化态氮含量范围为288.54~1123.27 mg﹒kg-1，均值为639.40 mg﹒kg-1，空间分布趋势与总氮一致；TF-N中各形态氮的大小顺序为：OSF-N（有机态和硫化物结合态）>IMOF-N（铁锰结合态）>CF-N（碳酸盐结合态）>IEF-N（离子交换态）。沉积物中TF-N主要以OSF-N（50.9%）和IMOF-N(33.3%)形态存在。OSF-N很难释放，不易参与氮循环。IMOF-N受水文条件影响显著，表现为在低水位高程和下采样站位沉积物中含量更低。淹水胁迫、水体富营养化等情况下氧含量较低，相对还原条件下有利于其向水体释放。而TF-N及其形态分布在垂直深度上无显著差异。可见，三峡库区特殊调蓄水制度加速了澎溪河下流、低水位高程消落带沉积物中IMOF-N向水体的释放。
