Abstract

一种车辆用供暖装置具有多个功率级。在这种供暖装置由一功率级转换到另一功率级时，换挡过程本身及供暖装置中燃烧器(2)的燃烧鼓风机(10)的转速的快速变化会引起恼人的噪声。为避免出现该噪声，在由一个功率级到另一功率级的转换时，本发明将燃烧鼓风机风扇转速的过渡过程设计平滑和渐变的。

Description

车用供暖装置
本发明涉及一种车用供暖装置，它包括一具有燃料供给装置和燃烧鼓风机的燃烧器和一加热功率调节装置，使用加热功率调节装置可实现不同功率级之间的转换，燃烧鼓风机在不同功率级时分别以一预定的转速运转。
已知有多种这样的供暖装置。按照一个或多个参数，例如热介质(空气或水)的温度来调节加热功率。
从前通常该种装置仅设有一个唯一的功率级，此时，燃烧器或开或关取决于一预定的温度，这另外会导致待加热区急剧的温度波动。
较舒适类型的该种装置设有多个例如两个功率级。在正常运行时，根据对调节过程起决定作用的参数大小进行诸如满负荷和部分负荷间经常的转换。
在由一功率级到另一功率级的转换过程中，特别会发生燃烧鼓风机转速的改变，相应地，经由燃料供给泵供应的燃料亦发生改变。
特别是不仅在使用继电器控制装置时燃烧鼓风机的转速转换会带来相当大的转换噪声，而且在使用半导体开关元件等此类装置时也会如此。燃烧鼓风机转速的急剧改变通常伴随有明显听得着的且可能会令人不舒服的噪声，噪声是由例如机壳或其它构件的振动引起的。
本发明提供一种弥补上述不足的方法，目的是改进前面所述的供暖装置，以便不同功率级之间的过渡过程基本上无噪声发生。
解决此任务的方法是将从一个功率级到另一功率级的过渡过程设计成平滑的过程。
这里“平滑过渡过程”特别是指没有燃烧鼓风机转速的突变。燃烧鼓风机例如由满负荷时的高转速下降到约其一半的部分负荷时，则“平滑过渡过程”发生在一时间间隔内，如一分钟内。而且转速增加时也有一相应时间间隔的过渡过程区。
结果令人惊喜，通过这样由一个到另一个功率级的一渐变过渡过程，燃烧鼓风机其转速改变过程基本上无噪声而不被人察觉。随着燃气鼓风机转速从一值到另一值的平滑过渡，燃料供给泵的功率其过渡过程亦不象往常普遍的那样突变，而是渐变的。
在极限情况下，燃烧鼓风机由一转速到另一转速的过渡过程所占时间很长，以致在达到所力求达到的功率级(燃烧鼓风机的转速)之前，就向反档方向转换，结果燃烧鼓风机转速例如逐渐下降之后，其转速随后会渐渐增加，反之亦如此。
下面依照附图对本发明一最佳实施例进行详述。附图中：
图1是车辆供暖装置方框图，
图2是供暖装置的燃烧鼓风机不同的转速曲线。
图1所示车辆供暖装置的构造本身是已知的。
为在燃烧室4中生成火焰，燃烧器2包括一带燃料泵8的燃料输入管6，用于往图1中未画出的汽化器、雾化器或者其它类似装置中输送燃料。燃烧鼓风机10用于按图示箭头方向输送燃烧用空气。运行周期开始时，点火装置12将燃料/空气混合物点燃，使在燃烧室4的焰道14中产生火焰。废气经由废气通道16逸出。
焰道14被水冷却套18包围，由一泵20循环其中用作热载体的水。温度传感器24采集出水口区域的水温，给出相应的信号到加热功率调节装置26。
焰道14和水冷却套18的结构形成一热交换器18，它用于把燃烧气体的热传导到位于水冷却套中的水中。按图示箭头方向流动的水由如图1右侧所示的水/空气热交换器28冷却。其中由热交换器28生成的热空气到达图中虚线所示的乘客车厢。
图2中“A”表示在图1左下方所示的燃烧鼓风机10的风扇转速随时间变化的曲线。在满负荷(VL)和部分负荷(TL)之间不断进行转换。该曲线相应与现有技术，因为在热功率控制装置26中的换档是通过继电器或通过半导体开关进行的。换档所产生的换档噪声以及燃烧鼓风机比较快的转速变化所产生的噪声按本发明应当被消除。
按图2中“B”曲线，由满负荷(VL)到部分负荷(TL)风扇转速的过渡过程是渐变的，例如，过渡过程时间超过一分钟。回档时由部分负荷(TL)到满负荷(VL)的过渡过程也是渐变的，如在约一分钟时间间隔内。
除了燃烧鼓风机10的转速外，还产生燃料泵8的功率变化；但是，鉴于其运转噪声不严重，所以在此它并不特别重要。
图2中曲线“C”表示了按本发明供暖装置亦或其运转的一种特殊情形。风扇转速由相应满负荷时的值过渡到相应部分负荷时的值的“渐变过渡过程”如此平缓，也就是说，转速下降的“时间常数”如此之大，以致于在低功率级完全达到之前，可能会发生功率增加方向的再度换档。时间常数对不同功率级之间的过渡过程长度起决定性作用，通过对其作相应调整，则能够达到几近正常运转状态。
图1所示的热功率调节换档装置包括相应的换档元件，用其可实现如图2B和C曲线所示的渐变过渡过程。特别是在热功率控制装置26中设有微处理器用以调整燃烧鼓风机转速的所期望的变化曲线。
