高层建筑热水供应系统能源选择的比较研究

Comparative Study of Energy Options in High-rise Building Water Supply Systems

从经济性及环境污染等方面比较研究了高层建筑各类热水供应系统能源类型的优缺点,通过对油、气、电三种热源进行比较,得出使用电力的能耗费用最高,其次是轻柴油,能耗最低的是天然气;若采用电蓄热式中央热水系统,会取得一定的社会和经济效益;燃油燃烧对大气的污染,比天然气燃烧造成的污染严重;指出选择清洁、无污染或少污染的燃料,对改善大气环境有着重要意义。

This paper introduces the advantages and disadvantages that the high-rise buildings of various types of hot water supply systems of energy from economic and environmental pollution. After Comparing the sources of heat of oil, gas and electricity, it shows that electricity use reached the highest energy costs, followed by light diesel oil, natural gas energy consumption is the lowest; If central hot water electric heat-storage system used ,that will achieve a certain degree of social and economic benefits. It also shows the fuel combustion will pollute worse than combustion of natural gas serious. So choosing the cleaning, non-polluting or less polluting fuel will improve the atmospheric environment significance.
