The present invention relates to a kitchen ventilation system to which a fan having a positive pressure-to-output characteristic is applied.
本发明涉及一种厨房通风系统，其应用了具有正压力至输出特征的风扇。I built an air ventilation system. I could have survived for weeks.
我做了个通风系统我可以在这里待好几个星期But then farms began to use new ventilationsystemsinsteadsystemsInstead of windows, the new systems used tunnel fans to circulate air.
但后来，农场开始使用新的通风系统以取代窗户，这种新系统利用通风扇的循环气流取代以前的窗户进行通风。Experts recommend that your ventilation system should provide at least one air change every hour.
专家推荐你的通风系统应该至少要每小时换一下气。Natural ventilation system of the building can be divided into wind pressure and thermal pressure ventilation systems by driving forces.
建筑的自然通风系统由于动力的不同而分为风压通风系统和热压通风系统。Therefore its ventilation capability and related emergency measures have to be reliable.
其通风系统平时运作与事故应变能力和处置措施必须确实可靠。The fuel tank of any motor vehicle must have some form of ventilation system.
任何汽车的油箱都装有通风系统。On this basis, the artificial neural network model and system architecture of the ventilation systems evaluation is established.
在此基础上，建立了评价通风系统的人工神经网络的数学模型和系统结构。But then farms began to use new ventilation systems. Instead of windows, the new systems used tunnel fans to circulate air.
但后来，农场开始使用新的通风系统以取代窗户，这种新系统使用隧道排气扇来循环空气。
