Abstract:

The building Norra Djurgården 43:12 on the main campus of the Royal Institute of Technology (KTH) in Stockholm will be retrofitted as students from the exter- nal campus Haninge will be moved there. This occasion is supposed to be used to improve the facility’s energy efficiency. Potential for this exists for both the space and the water heating system. The effect of decreasing the supply temperature to the radiators was examined based on equations for the heat transfer. It was calcu- lated that lowering the supply temperature by 5 K would reduce the space heating demand by 25 %, i.e. 94.25

Archaeological work had focused on collecting details of 160 cisterns and a small number of channels and pipes were incidental finds in other excavations. Although no-one had considered the water supply in Constantinople as a whole, the evidence seemed to indicate a sophisticated water management system. With the available data fragmented, and the potential for more evidence limited to serendipitous finds associated with construction work, the onl

Water supply system planning is concerned about the design of water supply infrastructure for distributing water from sources to users. Population growth, economic development and diminishing freshwater supplies are posing growing challenges for water supply system planning in many urban areas. Besides the need to exploit alternative water sources to the conventional surface and groundwater supplies, such as reclaimed water, a systematic point of view has to be taken for the efficient management of all potential water resources, so that issues of water supply, storage, treatment and reuse ar

In this research project, a series of obstructing devices were designed and tested for their ability to disrupt micelles and reverse the friction reducing effect in a 3/4 inch diameter stainless steel experimental test loop.

The thesis develops a high-volume water heater parallel system to cope with this problem. First, multiple cool water storage tanks are employed to store enough cool water. Next, the control valve is activated to heat cool water, when heated is to a setting temperature, the water is then transported to the hot water tank for storage. Finally, the needed heated water is delivered to the faucet or shower nozzle

M.Ing.<br>A one-year investigation on hot water consumption was conducted in South African developed and developing communities of Johannesburg to determine the personal and household average daily consumption of hot water as well as the average hourly (in summer and in winter) and monthly patterns. The motivation for this research project was to provide to engineers and water heaters manufacturers reliable experimental data on hot water consumption from various categories of dwellings. The existing sources of information in South Africa being extremely limited and results of estimations. The

碩士<br>國立交通大學<br>土木工程學研究所<br>86<br>The rapid growth on industrial and commercial development has greatly increased the demand for water. Through proper operation a water resources system achieve to satisfy various types of water demand. Due to the inherent hydrologic uncertainty and others, it is impossible and economically impractical to design a water resources project having a sufficient capacity for all demands. Therefore, to determine a reliable yield with an allowable shortage is a key issue for assessing in the performance of a water resources projects. Furthermore the issue on the toler

Consequently, concerns regarding the future water shortage in this area have emerged. Thus, this study adopted EPANET (version 2.0) software, which was developed by the U.S. Environmental Protection Agency (EPA), to investigate whether the existing water distribution network capacity in the Zhubei HSR special zone can fulfill the futu

abstract: Testing was conducted for a solar assisted water heater and conventional all electric water heater for the purpose of investigating the advantages of utilizing solar energy to heat up water. The testing conducted simulated a four person household living in the Phoenix, Arizona region. With sensors and a weather station, data was gathered and analyzed for the water heaters. Performance patterns were observed that correlated to ambient conditions and functionality of the solar assisted water heater. This helped better understand how the solar water heater functioned and how it may cont

The system can be used to assist reservoir managers for searching applicable rule of real-time reservoir operation. The DSS model is applied experimentally to the main reservoirs in Taiwan with success. The DSS includes three parts: (1) database information, (2) model information, and (3) operations information. In this study, first of all, streamflow over space and time at ungaged sites is estimated by using kriging geost

Typhoon Aere, striking northern Taiwan in 2004, caused high turbidity of inflow into the reservoir, and forced water purification plants to shut down. This resulted in suspension of the water supply in Taoyuan for over 2 weeks. In order to solve the water deficit dilemma, Water Resources Agency formulated project “Implementation Plan of Shihmen Reservoir and Its Catchment Management Project”.
