空气采暖的方法铁路客车的传统采暖法是对流采暖,从有铁路的初期起即不用燃材或烧煤的炉子采暖。对流采暖利用对流加热体,它装在窗壁的地板处和座位下方。蒸汽与热水采暖时的加热体由一些管路和暖气片组成,电热采暖时对流加热体是电阻加热器。室内空气在对流加热体表面被加热,加热后重量减轻而上升,上升过程中被冷却而下降又重复加热,完成一定的循环途径。因此,对流采暖(人们都忽略了它的辐射加热部分)也是一种热空气采暖,但空气的流动场完全是由于室内不同空间、不同温度的空气具有不同重量而产生的,并且采暖设备不从 Air heating method The traditional heating method of railway passenger cars is convection heating, from the early railway that is not burning fuel or coal stove heating. Convective heating uses a convection heating body, which is mounted on the floor of the window wall and under the seat. Steam and hot water heating body by a number of pipes and radiators composed of electric heating convection heating body is a resistance heater. The indoor air is heated on the surface of the convection heating body, the weight decreases after heating, and rises while being cooled down and then heated repeatedly to complete a certain circulation route. Therefore, convection heating (people ignore the radiation heating part) is also a hot air heating, but the air flow field is entirely due to different indoor space, different temperatures have different weights of air produced, and heating equipment not from
