THERMO-ECONOMIC ANALYSIS OF CONCENTRATED SOLAR HEAT APPLICATIONS IN HOSPITALITY INDUSTRIES

Abstract

Indian hospitality industries are under considerable strain to move from fossil fuel to clean energy technology. Hospitality industry is one of the major industries in India which have huge energy requirements in the form of both electrical and thermal. Hospitality industry involves various heat processing steps like in kitchen, for laundry and for bathing. The use of an appropriate solar thermal technology can have a positive impact on the energy and environment scenario of hospitality industry at a large. There are various solar thermal technologies including CST technologies that are available for hospitality industries. Objective of the present work is to design solar paraboloid dish based heat system for Indian hospitality industries for cooking, laundry and bathing purpose. A solar paraboloid dish is designed with dual axis tracking for better efficiency. Concentrating characteristics of the sunlight have an important effect on the optical-thermal conversion efficiency of solar concentrator and the application of the receiver. Result of the performance of 14 m diameter solar paraboloid dish at Delhi site has been compiled with major parameters like physical dimensions of the paraboloid dish, energy generation potential of single dish and complete array, total energy requirement for plant, integration within plant, costing of the installation of SIPH system and its economic analysis in the form of payback period. The solar paraboloid based SIPH system can be installed at various hospitality industrial plants with region of high DNI values to make hospitality industry more environment friendly by reducing green house gas (GHG) emissions. Also SIPH system will help companies’ dependence of quickly depleting fossil fuels for thermal energy requirements and save them from highly fluctuating fossil fuel prices. Finally the technical feasibility of the solar process heating system for the industry has been proved along with its economic feasibility.
