Question

随着我国城镇化的快速发展，建筑能耗逐年递增。在能源、环境问题日益严重的今天，开发和利用新能源已成为当今社会最热门的课题之一。太阳能作为最重要的新能源代表更是深受青睐，其供热采暖技术从以前的单体建筑小型系统发展成为大中型区域的集中供暖系统。因其节能、环保的优点逐渐成为建筑节能设计的重要设计方式。鉴于此，本设计主要对兰州市某办公楼进行太阳能供暖系统设计，在设计中先确定供暖系统方案，然后分别完成建筑物的热负荷计算、末端装置设计计算、采暖系统水力计算、太阳能集热器以及辅助热源、蓄热水箱、循环水泵、定压装置、水处理装置的选型设计计算，最后进行能耗分析。从结果可以看出太阳能供热采暖技术具有明显的经济实用性，同时，希望通过本设计能为同类工程提供借鉴参考，对太阳能供热采暖技术的推广起到一定的作用。

Answer 1

With the rapid development of urbanization in our country, building energy consumption is increasing year by year.In today's energy and environment problem is increasingly serious, the development and utilization of new energy has become one of the hottest topics in today's society.Solar energy is highly appreciated as a representative of the most important new energy, the heating technology from the previous monomer building small systems become large and medium-sized regional central heating system.Because of its advantages of energy-saving, environmental protection gradually become important design method of building energy efficiency design.In view of this, the design is mainly for lanzhou city a building to design the solar heating system, heating system plan in the design, then respectively to complete the structure of the heat load calculation, terminal device design calculation of hydraulic calculation, heating system, solar collector and auxiliary heat source, heat storage water tank, circulating pump, constant pressure equipment, water treatment equipment type selection design calculation, analysis of energy consumption in the end.As can be seen from the results of solar heating technology has obvious economic practicability, at the same time, hope that through this design can offer reference for the similar engineering reference, for the promotion of solar energy heating technology play a role.
