说实话草莓视频在线看片都知道，负压草莓视频入口和正压草莓视频入口是一个通风降温功效十分非常好的设施。问题来了，什么是负压草莓视频入口和正压草莓视频入口呢?一起来掌握下。　　

什么是负压草莓视频入口和正压草莓视频入口

　　负压草莓视频入口因为它的特性是由居室的空气排掉、使居室空气稀缺而相对性外部是属于气体压强为负值，因而就叫负压草莓视频入口。

　　而正压草莓视频入口，能解读为强制性送风进居室，换句话说将佳锋负压草莓视频入口的安装大方向、由原来的向外排气管变为往里面送风，这就是正压草莓视频入口了。

　　负压草莓视频入口因为它的特性是由居室的空气排掉、使居室空气稀缺而相对性外部是属于气体压强为负值，因而就叫负压草莓视频入口。正压草莓视频入口将佳锋负压草莓视频入口的安装大方向、由原来的向外排气管变为往里面送风。

　　负压草莓视频入口的原理是当电动机根据连轴器或皮带轮推动主动轴旋转时，组装在转动轴上的传动齿轮推动从动轮上的传动齿轮，按相反方向同歩转动，使齿合的电机转子相伴旋转，进而使壳体与电机转子产生一个室内空间，汽体从进风口进入空间。这时候空气会得到缩小并被电机转子挤压排气口，而另一个电机转子则转至与**个电机转子在缩小逐渐的相对位置，与壳体的另一边产生一个新领域，一个新的汽体又进到这一室内空间，被挤出出。持续健身运动进而做到鼓草莓视频入口的目地。

　负压草莓视频入口和正压草莓视频入口的差别

　　1、组装不一样

　　正压草莓视频入口一般安装在房屋建筑相对性高的窗子，而负压草莓视频入口一般会安装在厂区的窗户外，安装到下风口，有利于向外边排风，室外新鲜的空气进到，具有空气热对流的功效。

　　2、排气管基本原理不一样

　　负压草莓视频入口是向外排出空气，让居室空气稀缺，进而造成负压力区，外部的空气流进来，具有通气的实际效果。

　　正压草莓视频入口恰好相反，这是向居室抽真空。

　　3、作用不一样。

　　负压草莓视频入口重点是通风降温、清除臭味及其清除尘土。

　　正压草莓视频入口一般情况下多运用在脱险楼梯道中，当发生安全事故情况下，其里边的电机遇打开出风口，感温烟感探测器或手动式消防报警系统会运行，塔屋顶正压草莓视频入口自动式打开，对送风立井施加压力送风，室内楼梯的前处理室通过正压送风嘴会持续不断的对前处理室送风，让前处理室维持正压，保证烟尘不会再此地域扩散，而给人脱险的室内空间。当环境温度超出280℃世人早已并没有脱险的很有可能，其里边断路器会融断，出风口自动式关闭，防止火灾扩散。

　　另一种正压草莓视频入口与负压草莓视频入口差别:

　　一、基本原理不一样

　　1、正压草莓视频入口：将户外气压送进房间内。

　　2、负压草莓视频入口：向外排出来空气使房间内标准气压降低，房间内空气变较稀，产生一个负压力区，空气因为气压差赔偿注入房间内。

　　二、产品特点不一样

　　1、正压草莓视频入口：当一栋草莓视频APP色版下载建筑发生火灾时，它会造成很多的浓烟、一氧化碳等有害气体并阻塞视野，根据正压通草莓视频入口逃出消防楼梯，使房间内浓烟没法抵达室内楼梯，为大家脱险发挥特长。

　　正压草莓视频入口一般组装在房屋建筑顶端，与各层正压电动风阀相接。火灾事故前期，开启进气阀，运行正压草莓视频入口，使楼梯口、电梯间处在正压情况(送风情况)。

　　2、负压草莓视频入口：整个设备选用CAD/CAM设计，具备注资低成本、排风量大、噪音低、耗能低、运作平稳、使用寿命长、效果好等特性。百叶窗帘可自动升降关掉，做到防污、防潮、漂亮的目地。可吹草莓视频入口或排风，是当代生产车间制冷自然通风的**的选择。环境保护环保型负压草莓视频入口将变成通风设备销售市场的流行。

　　To tell the truth, we all know that negative pressure fan and positive pressure fan are very, very good facilities for ventilation and cooling. The question is, what are negative pressure fans and positive pressure fans? Let's master it together.

　　What are negative pressure fan and positive pressure fan

　　Negative pressure fan is called negative pressure fan because its characteristic is that it is discharged by the air in the room, making the air in the room scarce, and the external relativity is that the gas pressure is negative.

　　The positive pressure fan can be interpreted as forced air supply into the room. In other words, the installation direction of Jiafeng negative pressure fan is changed from the original outward exhaust pipe to inward air supply. This is the positive pressure fan.

　　Negative pressure fan is called negative pressure fan because its characteristic is that it is discharged by the air in the room, making the air in the room scarce, and the external relativity is that the gas pressure is negative. The positive pressure fan changes the installation direction of Jiafeng negative pressure fan from the original outward exhaust pipe to inward air supply.

　　The principle of negative pressure fan is that when the motor drives the driving shaft to rotate according to the coupling or belt pulley, the transmission gear assembled on the rotating shaft drives the transmission gear on the driven wheel to rotate in the same step in the opposite direction, so that the toothed motor rotor rotates together, so that the housing and the motor rotor create an indoor space, and the steam enters the space from the air inlet. At this time, the air will be reduced and squeezed by the motor rotor into the exhaust port, while the other motor rotor will turn to the relative position with the first motor rotor gradually reduced, creating a new field with the other side of the shell, and a new steam will enter the indoor space and be squeezed out. Continue to exercise to achieve the goal of the blower.

　　Difference between negative pressure fan and positive pressure fan

　　1. Different assembly

　　The positive pressure fan is generally installed in the windows with high relativity of buildings, while the negative pressure fan is generally installed outside the windows in the plant area and installed at the lower air outlet, which is conducive to the outward exhaust, and the outdoor fresh air enters, with the effect of air heat convection.

　　2. The basic principle of exhaust pipe is different

　　The negative pressure fan is used to discharge the air outward, which makes the air in the room scarce, and then causes the negative pressure area. The external air flows in, which has the actual effect of ventilation.

　　Positive pressure fan is just the opposite, which is to vacuum the room.

　　3. The effect is different.

　　The key points of negative pressure fan are ventilation and cooling, odor removal and dust removal.

　　Normally, the positive pressure fan is mostly used in the escape stairway. In case of safety accident, when the motor inside opens the air outlet, the temperature and smoke detector or the manual fire alarm system will operate. The positive pressure fan on the tower roof will automatically open to apply pressure to the air supply shaft. The pre-treatment room of the indoor stairs will continuously supply air to the pre-treatment room through the positive pressure air supply nozzle, so that the pre-treatment room can maintain positive pressure, Ensure that the smoke and dust will not spread in this area and give people an indoor space to escape from danger. When the ambient temperature exceeds 280 ℃, it is very likely that the world has not been out of danger for a long time. The circuit breaker inside will melt off and the air outlet will be closed automatically to prevent the spread of fire.

　　Difference between another positive pressure fan and negative pressure fan:

　　1、 Different basic principles

　　1. Positive pressure fan: sends outdoor air pressure into the room.

　　2. Negative pressure fan: the air discharged from the outside reduces the standard air pressure in the room, and the air in the room becomes thinner, creating a negative pressure zone. The air is injected into the room because of the pressure difference.

　　2、 Different product features

　　1. Positive pressure fan: when a fire occurs in an engineering building, it will cause a lot of smoke, carbon monoxide and other harmful gases and block the view. According to the positive pressure fan, it escapes from the fire stairs, making it impossible for the smoke in the room to reach the indoor stairs, so as to give full play to its strengths for everyone to escape from danger.

　　The positive pressure fan is generally assembled at the top of the building and connected with the positive pressure electric air valve on each floor. In the early stage of the fire accident, open the air inlet valve and operate the positive pressure fan to make the stairwell and elevator room under positive pressure (air supply).

　　2. Negative pressure fan: cad/cam design is adopted for the whole equipment, which has the characteristics of low capital injection cost, large exhaust air volume, low noise, low energy consumption, stable operation, long service life and good effect. The shutter curtain can be automatically lifted and closed to achieve antifouling, moisture-proof and beautiful destination. It can be blower or exhaust, which is the best choice for natural ventilation of refrigeration in contemporary production workshops. Environmental protection and environmental protection type negative pressure fans will become popular in the ventilation equipment sales market.

　　The above difference between positive pressure fan and negative pressure fan was created by Shanghai Ruizhe environmental protection Co., Ltd. at the end of June 2022!
