6) adaptive demand-controlled ventilation
自适应按需新风控制
1.
For multi-zone variable air volume(VAV)air conditioning systems,presents an adaptive demand-controlled ventilation(DCV)strategy with temperature resetting in critical zones to meet the indoor air quality demand of each zone with minimum energy consumption.
针对多区域变风量空调系统,提出一种关键区温度重设定的自适应按需新风控制策略,以最少的能耗满足各区的室内空气质量要求。

按需型心室起搏器
demand ventricular pacemaker
该起搏器内有一个感知装置，可感知心室自身活动，如果心脏本身的节律比预设的起搏频率快，感知装置即断开起搏器；当患者自己的心率比预设的起搏频率慢时，感知装置又起动人工起搏器。因此对短暂或间歇性心动过缓较为安全。此外节省电能，在埋藏式起搏器中可维持较长时间。
