摘要
城市中各类商业建筑卫生热水能耗占这些建筑总能耗的比例达到10%～40%,城市民用建筑热水能耗约为城市民用总能耗比重的20%～30%,节能是热水技术发展的永恒主题。电热水器、燃气热水器的技术已趋于完善,但从根本上只是“热水壶的高档化”,高能耗是常规热水技术无法克服的缺憾;深化开发太阳能、热泵热水器是热水器发展的两个必然方向,政府应从可持续发展角度出发,加大支持力度。
Energy efficiency is the perpetual subject of water heaters development, for energy consumption for heating water has takes account 10%～40% of total energy consumption of commercial buildings in urban district, and the amount of civil buildings is 20%～30%. In the view of energy efficiency, consummating electric or gas water heaters are essentially high-grade kettles for their insurmoun table shortcomings of inefficient energy consumption, so deepening development of solar or heat pump water heaters are the inevitable approaches of developing water heaters in the future. It is suggested that, and governmental departments should strengthen the support of these technologie sincrease the strength of policy supports for the sustainable development of society.
