在特定的流动条件下,一部分流体动能转化为流体振动,其振动频率与流速(流量)有确定的比例关系,依据这种原理工作的流量计称为流体振动流量计。目前流体振动流量计有三类:涡街流量计、旋进(旋涡进动)流量计和射流流量计。流体振动流量计具有以下一些特点: 1)输出为脉冲频率,其频率与被测流体的实际体积流量成正比,它不受流体组分、密度、压力、温度的影响; 2)测量范围宽,一般范围度可达10:1以上; 3)精确度为中上水平; 4)无可动部件,可靠性高; 5)结构简单牢固,安装方便,维护费较低; 6)应用范围广泛,可适用液体、气体和蒸气。 本文仅介绍涡街流量汁(以下简称VSF或流量计)。

工程技术上所谓的制冷,就是使某一系统(即空间或物体)的温度低于周围环境介质的温度,并维持这个低温的过程,这里所说的环境介质是指自然界的空气和水。制冷与空调设备以流体(气体与液体的总称)作为载能物质,实现热能与其它形式能量(主要为机械能)之间的转换或热能的转移。本章介绍流体的性质、热能与机械能之间的转换规律和热量的传递规律,这些知识是空调技术必不可少的理论基础。

Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many power-delivery solutions. Yet sometimes a device has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.
