  • applying a novel extra low temperature dedicated outdoor air system in office buildings for energy efficiency and thermal comfort
    Energy Conversion and Management, 2016
    Co-Authors: Han Li
    Abstract:

    Abstract A novel dedicated outdoor air system consisting of a multi-stage direct expansion coil and a zero-energy heat pipe to geneRate extra-low temperature outdoor air to avoid moisture-related problems was proposed in this study. The proposed system’s performance in achieving the desirable air conditions and better energy efficiency objectives is compared with a conventional direct expansion system for air-conditioning of a typical office building in Hong Kong based on simulation investigations. The simulations were carried out using equipment performance data of a pilot study, and realistic building and system characteristics. It was found that the proposed system, as compared to the conventional system, could reduce the annual indoor discomfort hours by 69.4%. An energy and Exergy analysis was also conducted. It was revealed that the proposed system could reduce the annual air-conditioning energy use by 15.6% and the system Exergy Loss Rate by 13.6%. The associated overall Exergy efficiency was also found 18.6% higher. The findings of this study confirm that the proposed system is better than the conventional system in terms of both energy and Exergy efficiency and the desirable air conditions.

  • studies of the unavoidable Exergy Loss Rate and analysis of influence parameters for pipeline transportation process
    Case Studies in Thermal Engineering, 2018
    Co-Authors: Qinglin Cheng, Anbo Zheng, Hao Wu, Lu Yang, Lili Lv
    Abstract:

    Abstract According to the Exergy balance relationship among the various items in the crude oil transportation process system, the Exergy balance equation is established and each Exergy Loss is calculated. In a sense, the essence of Exergy analysis method relies on the calculation and the analysis of system Exergy Loss. The unavoidable Exergy Loss is defined based on the required minimum Exergy Loss from the technology standpoint during the pipeline conveying process. In order to truly reflect the degree of effective energy utilization, this article puts forward the unavoidable Exergy Loss Rate as evaluation index, which is based on the Exergy analysis criterion consisted by Exergy Loss coefficient and Exergy Loss Rate. Taking an oil pipeline as an example, the changes of the unavoidable Exergy Loss are studied under different designed parameters. And the unavoidable thermal Exergy Loss is the dominant position. Change situations of the unavoidable Exergy Loss Rate are explored. Through analysis, the trend and the regularity of the unavoidable total Exergy Loss Rate are identical with the unavoidable thermal Exergy Loss Rate. Then the orthogonal experiment method is used to compare the different influence degrees to the pipeline unavoidable Exergy Loss Rate. The results are as follows: diameter, insulation thickness and buried depth, which can provide the reference for the energy-saving transportation of crude oil pipeline.

    Abstract:

    Abstract In order to ensure the crude oil pipeline process smoothly, the driving force has a certain Exergy Loss. Based on the Exergy analysis method, according to the required minimum potential difference of pipeline transportation, the unavoidable Exergy Loss is defined in the process. In order to reflect the real effective utilization degree of energy consumption, the unavoidable Exergy Loss Rate is put forward as the evaluation index. And it is calculated by the ratio of related the unavoidable Exergy Loss and the Exergy Loss. The crude oil pipeline Exergy Loss Rate is calculated under different conditions. The orthogonal experiment analysis used to compare the influence degree of different operating parameters on the pipeline unavoidable Exergy Loss Rate show that the influence degree on the unavoidable Exergy Loss Rate in turn is: outbound temperature, flow and outbound pressure. It also provide the reference for the energy-saving transportation of crude oil pipeline.

    Co-Authors: Mohammad Hossein Kaveh, Yousef Abbaspourgilandeh, Guangnan Chen
    Abstract:

    Abstract The purpose of this paper was to study the drying kinetic, quality, energy and Exergy performance of green peas in a hot air-rotary drum dryer using the Adaptive Neuro-Fuzzy Inference System (ANFIS) model. The effect of air temperature and rotary rotation speed was examined. The drying tests were performed at three air temperature levels of 40, 55 and 70 °C and three rotation speeds of 5, 10 and 15 rpm. The modeling of kinetic, quality (color, shrinkage, and rehydration ratio), energy and Exergy indices of the green pea drying was also investigated using the adaptive neuro-fuzzy inference system (ANFIS). The results showed that the energy utilization Rate of the process varied in the range of 0.0121–0.1556 kJ/s. The minimum and maximum values of energy utilization ratio were respectively obtained in the drying conditions at 70 °C and rotation speed of 15 rpm, and at 40 °C and rotation speed of 15 rpm. Reducing the drying temperature and speed of rotation reduced the quality properties. Minimum values of color (△E) and shrinkage was 64.95 ± 1.67 and 39.19 ± 1.05, respectively. The Exergy Loss Rate and average Exergy efficiency varied from 0.02 to 0.11 kJ/s and from 0.5434 to 0.8382, respectively. The average Rate of Exergy improvement potential increased with increasing air temperature and rotary rotation speed. The highest R2 value for the prediction of moisture ratio, energy utilization, energy utilization ratio, Exergy Loss and Exergy efficiency with the ANFIS model was 0.9996, 0.9999, 0.9995, 0.9989 and 0.9996, respectively.
