Carbon Footprint Analysis at the Operation Phase in a Student Residential Hall in Hong Kong
Get PDFAccording to the climate action plan published by the Environment Bureau in Hong Kong, it is expected that the absolute carbon emission to have a reduction of 36% per capita by 2030 (base year 2005). Using walkthrough combined with energy simulation, we have investigated the energy consumption pattern of a student residential hall. Due to the fluctuation nature on the number of residents in a student residential hall, we have simulated several scenario: 1) typical occupancy, 2) typical occupancy with energy optimization, 3) peak occupancy, 4) peak occupancy with energy optimization in order to estimate the range of consumption. In scenario 4, effective energy use pattern for air-conditioning system was implemented and approximately 480 tonnes (6.5%) of carbon emission can be reduced for a 50 years building life span consideration. Various energy conservation measures should be taken into consideration in order to further reduce carbon emission in the future
Mechanism of Water Oxidation by Ferrate(VI) at pH 7 – 9.
No full textThe kinetics of water oxidation by K2FeO4 has been reinvestigated by UV/Vis spectrophotometry from pH 7–9 in 0.2 m phosphate buffer. The rate of reaction was found to be second‐order in both [FeO42−] and [H+]. These results are consistent with a proposed mechanism in which the first step involves the initial equilibrium protonation of FeO42− to give FeO3(OH)−, which then undergoes rate‐limiting O−O bond formation. Analysis of the O2 isotopic composition for the reaction in H218O suggests that the predominant pathway for water oxidation by ferrate is intramolecular O−O coupling. DFT calculations have also been performed, which support the proposed mechanism
Further development of a thermal comfort based fuzzy logic controller for a direct expansion air conditioning system
No full textThe primary purpose of A/C is offering occupants with acceptable indoor thermal comfort levels. Thermal comfort is a complicated result of non-linear interactions between six parameters. However, many of current A/C systems solely control air temperature. Whenever anyone of the five parameters other than temperature varies significantly, an occupant may feel thermally uncomfortable. To address the issue, a comprehensive thermal comfort index should be used as regulator in A/C systems. One fuzzy logic controller is available. However, the approach to the fuzzy logic controller is complicated. In this paper, one previous established fuzzy logic controller is simplified for its real application. Test results demonstrated that the simplification would not reduce the control performances in terms of control accuracy and sensitivity. A local fan was installed in the conditioned space to act as personalized ventilation. It is shown that at the same thermal comfort level, about 4–7.6% energy saving of the A/C system could be achieved when a higher local fan speed was used. With simplifications, the thermal comfort based fuzzy logic controller has a high potential of commercialization. It can contribute to the realization of low carbon A/C systems while improving indoor thermal comfort for building occupants
