太阳能热水器与居住建筑热水节能

介绍了我国居住建筑热水的能耗现状，太阳能热水器在热水节能中的最新进展、节能性、经济适用性。太阳能热水器的经济性取决于气候条件、系统造价、能源价格体系等多种因素。有必要进一步提升太阳能热水器性能，特别是提高气候适应性。改进建筑规划设计，实现太阳能热水器与建筑的有机结合．太阳能热水器的推广应当细分市场，对于中国广大农村，整体式、平板型太阳能热水器更有适应力。

Solar Water Heater and Hot Water Energy-saving in Residential Building

The present states of hot water energy consumption in Chinese residential buildings, the recent progress, energy-saving efficiency and economic applicability of solar water heater in hot water energy-saving are introduced. The economic efficiency of solar water heater depends on climate conditions, system fabrication cost, energy price system and other factors. It is necessary to further improve the performance of solar water heater, especially its climate adaptability. The organic combination of solar water heater with building carl be achieved by improving the architectural planning design. The promotion of solar water heater should be based on market segmentation. For the vast countryside in China, the integrated collector storage solar water heater and flat plate solar water heater have better adaptability.
