counterflow

基本解释

The ventilation system consists of a supply and exhaust air unit with a counterflow heat exchanger which provides 85% heat recovery.
通风通风系统包括一个送风单元，一个排风单元，与一个可回收85%热能的逆流式换热器。
For example, shifting beds are improved to be floating beds, which have both advantages of high effluent as in shifting beds and of low consumption of counterflow regeneration as in fixed beds.
如移动床改造成浮动床，它具有移动床出水大和固定床逆流再生消耗低的优点，克服了移动床设备维修和操作工艺复杂等缺点。
Lastly, the results of unsteady flow point out, counterflow thrust vectoring nozzle is a efficiency fluidic vectoring nozzle.
最后，非定常流的结果进一步表明，逆流喷管是一种较高效率的射流式矢量喷管。
