loss ventilation的意思|示意

The positive crankcase ventilation valve and gas caps with air-pollution control valves reduce volatile organic compound loss.

曲柄轴箱通风阀和配有废气帽的空气污染控制阀(的使用)对减少挥发性有机混合物释放有积极作用。

At the same time, excessive heat loss by ventilation in winter periods must be minimized.

同时，冬季通风带走的额外热损必须最小化。

For each project, we calculate the heat loss, the potential humidity levels and the ventilation requirements, in order to design a "system" for your unique air management needs.

对于每个项目，我们都会计算热量损失，潜在湿度水平和通风的要求，以达到你独特的空气管理要求。

The both methods enjoy advantages of higher production capacity, lower development ratio, less dilution loss and better ventilation.

两种方法均具有生产能力高，采掘比低，贫化损失较小，改善通风条件等优点。

The heat loss caused by natural ventilation is very important for energy audit and air-conditioning design of buildings.

自然通风热损失对建筑物的空调设计和能量审计是非常重要的。

Through the discussion of the resistance properties of natural ventilation induced by wind force, a method of local pressure loss superposition was proposed to calculate the pressure loss.

探讨了风压作用下大开口的自然通风阻力特性，并提出了用局部损失迭加法来计算阻力损失，即认为通过建筑物的气流是由不同的突缩段和突扩段的组合。
