The Research Of Solar Energy Application In The Construction Of Universities

With the development of economy, improving our quality of life at the same time,the deterioration of the environment problems are more serious, the new campusconstruction of colleges and universities nationwide general, great energy consumption,countries are also trying to promote clean energy and non conventional energy use, inorder to save conventional energy source, solve the problems of conventional (fossil)energy consumption, reduce emissions objective to Protect environment of carbondioxide.This study is based on this background, the solar energy has been studied in theapplication and economic benefits, and take Xi’an University Of Architecture AndTechnology Caotang campus solar hot water project as a case study of specific, detaileddiscussion of the related technologies to build solar heating reform and implementationstrategy, and focus on three aspects of economic benefits, energy efficiency and theenvironmental benefits of solar hot water project in the application effects of thecampus was evaluated. The evaluation can be seen, in the economic benefits, the projectbalance benefit cost ratio to return2.05. to demonstrate the benefits of the project costwas higher than that of. Investment recovery period and the project for6.73years. Xi’anUniversity Of Architecture And Technology Caotang campus use of solar heating forpre project cost shortest can be recovered in6.73years, has a higher rate of return oninvestment. From energy saving point of view, the project application, the averageannual savings of227244.9cubic meters of natural gas, calculated in accordance withthe market price of2.4yuan per cubic meter, the average annual can save natural gas costs545900yuan. As can be seen, the solar water heating way banned in natural gasboiler heating water system has significant benefits in energy conservation. Finally,from an environmental point of view, the calculation can be seen, compared withnatural gas hot water supply, solar heating levels were reduced annual362.46tons ofcarbon emissions. According to the calculation of15years service life of water supplysystem of solar energy, its life cycle that can reduce carbon dioxide emissions reached5436.974tons. Therefore, the use of solar energy the way effectively reduces thepollution of the environment.Based on the above analysis we can see, the Xi’an University Of Architecture AndTechnology Caotang campus using solar water heating mode in the investment recoveryhas significant economic benefit and environmental benefit period, energy conservationand environmental protection, and to save conventional energy, reduce emissions ofcarbon dioxide to Protect environment.
