PAGE 32 珠海某酒店太阳能热水系统设计 摘 要 目前，中国城市化的进程日新月异，而整个建筑行业在这个过程中需要消耗的能源尤为巨大，可以达到整个国家行业能源总耗的24%~29%。依照欧美国家的城市化发展历史，随着整个国家城市化的高速发展，建筑行业的能耗一定会远远超出化学、运输、工业等其他行业，成为社会能耗的首位，最终占到整个国家总行业能源消耗的33.5 %以上，而全球总能耗的1/4才能满足中国城镇与农村建筑的能耗需求。所以，中国目前的节能工作属于重中之重，是解决国家能源供给和经济发展能耗需求的不平衡矛盾的最有效措施之一。太阳能是当今环保安全、绿色无污染的可再生能源之一，资源总量巨大，是地球已探测煤炭储量的1.7亿倍，而且分布广泛，与建筑能源的品位需求相符合。但由于中国当今太阳能热水系统的发展起步较晚，还处于摸索阶段，对于应用产品的质量也参差不齐，在没有统一规范的情况下，不同厂家生产出来的产品在规格，尺寸，具体参数上有较大差异，再加上客户的需求往往不尽相同，因此，根据具体酒店设计相对应的太阳能热水系统对于其实际应用至关重要。 本此设计中的酒店采用的为闭式强制循环、间接加热系统，通过利用太阳能热水传递热量，当太阳能资源丰富时将冷水加热，直至达到所设计的热水温度后供给用户使用；同时增加空气源热泵作为辅助热源，在太阳能资源匮乏时由辅助热源来加热冷水。此太阳能系统包含:集热系统、换热系统、储热系统、热水系统以及辅助热源。 关键词：太阳能应用；集热器；热水系统；热泵； Design of solar water heating system for a hotel in Zhuhai Abstract At present, Chinas rapid urbanization process, the entire construction industry in the process of energy consumption is particularly huge, can reach the national industrial energy consumption of 24%-29%. From the perspective of the history of urbanization, with the rapid development of urbanization in Europe and the United States, building energy consumption will far exceed that of chemical, transportation, industrial and other industries, and become the largest energy consumption in the society, exceeding 33.5% of other industries. Industrial energy consumption accounts for only a quarter of the worlds total energy consumption, meeting the needs of urban and rural development.Therefore, Chinas current energy conservation work is the top priority, and it is one of the most effective measures to solve the imbalance between the national energy supply and the energy consumption demand of economic development. Solar energy is a kind of environmental friendly, safe, green and pollution-free renewable energy.The total amount of resources is huge, which is 170 million times of the earths explored coal reserves, and widely distributed, which is consistent with the grade demand of building energy. However, as the development of solar hot water syst
