文档介绍：摘要
人们在日常生活和社会生产中都需要使用大量的热能。将自然界的能源直接或间接地转化为热能,以满足人们需要的科学技术,称为热能工程。供暖就是用人工方法向室内供给热量,使保持一定的室内温度,以创造适宜的生活条件或工作条件的技术。所有供暖系统都由热媒制备(热源)、热媒输送和热媒利用(散热设备)三个主要部分组成。
本设计主要采用集中式供热系统,散热器给室内供热方式有对流供热和辐射供热。根据此建筑物的特点采用垂直单管跨越式同程系统,此系统的好处是既可以避免垂直方向的垂直失调,即底层用户不至于过冷;又可以避免水平方向的水平失调,即不至于使距干管最远用户无法达到要求的温度。同时,还考虑了经济、可靠、节能等方面。

Abstract
The people all need to use mass heat energy in day-to-day life and society produce. The sources of energy with nature directly or a ground connection changes to heat energy, are called the heat energy engineering with the science and technology that satisfies people's needs. The heating supplies quantity of heat to the indoor with the man-made method exactly, the indoor temperature that makes to keep fixed, and with the technology to create suitable living conditions or hot conditions. All heating systems are all prepared ( heat source ) by hot matchmaker and hot matchmaker transport and hot matchmaker use ( dissipating heat equipment ) three major parts to form.
This design chiefly adopts concentrated(ly) type supplies the hot system, the radiator supplies that the hot method has the convection to supply to heat up and the radiation supplying heating up to the indoor. The characteristic according to
this building adopts perpendicular one pipe striding across type with the range system, and the benefit of this system is can avoid the perpendicular imbalance of above-below direction, namely first floor user does not go so far as the overcooling; Can avoid the horizontal imbalance of horizontal direction, and does not go so far as to make again apart from doing the temperature that the farthest away user of pipe can not achieve the requirement. At the same time, still think over economically and the aspect synthesis such as reliable and save energy etc thinking over.
Key Words: Heating systems; Hot matchmaker; Heat source; Convection; Radiation
