| Abstract | In this study, governing equations were developed to model energy intensity containing within the spinning products. The models are intended to characterize energy efficiency of the industry, and further to explain energy consumption within various consumption situations mainly on the potential of saving electricity in application of the open air loop operation of air washer within Bangkok climate. To point out the influential parameters of the mathematical models, a selected factory was investigated in order to find its manners of production, energy consumption and co-relationship between energy and production characteristics. Parameters gathered from the factory investigation are comprised with psychometrics, and heat and mass balances to present the models. According to the model construction, influential factors of energy efficiency in spinning industry are fineness of spun yarn, adjustment of requisite ambient condition in the factory and machines' technology. A computer program was written to reduce the routine calculations. The models were verified by real condition. Furthermore, they were used to predict the effects of various parameters and also under the feasibility to improve efficiency. Consequent from the computer program computations, energy intensity existing of factory in Bangkok's climate is relatively high, application of the Open-Loop operation is much beneficial, however, the figure of energy efficiency existing in any applications cannot be precisely determined, since amount of energy consumption is much varied by the fineness of spun yarn. In addition, by increasing in requisite ambient temperature and relative humidity inside the mill to the maximum allowable range of yarn production quality control, can provide more energy saving from air conditioning system. Further, scenarios for energy efficiency improvement implementation were projected. Impacts of the proposed application under various environments on the textile & leather sector expressed relatively attractiveness. |
