负压风机是怎么降温的?

发布时间:2019/05/21

  负压风机是怎样给我们降温的,是什么原理呢?今天就给大家细致的引见一下,希望大家可以分明这些方面的问题。
  How does the negative pressure fan cool us? What is the principle? Today I would like to give you a detailed introduction. I hope you can clarify these issues.
  负压风机应用机械动能强迫使室内空气排出室外,使室内气压降落,室内空气变稀薄,构成一个负压区,空气由于气压差补偿流入室内。在工业厂房实践应用中,负压风机集中装置于厂房一侧,进气口于厂房另外一侧,空气由进气口到负压风机构成对流吹风。
  The negative pressure fan uses mechanical kinetic energy to force the indoor air to discharge outdoors, which makes the indoor air pressure drop and the indoor air become thinner, forming a negative pressure area. The air flows into the room due to the compensation of the air pressure difference. In the practical application of industrial plant, the negative pressure fan is centralized on one side of the plant, the air inlet is on the other side of the plant, and the air is convective blown from the air inlet to the negative pressure fan.
  在这个过程中,靠近负压风机左近的门窗坚持关闭,强迫空气由进气口一侧门窗补偿流入车间。空气排着队、有次序的由进气口流入车间,从车间流过,由负压风机排出车间。换气彻底、高效,换气率可高达99左右%。
  In this process, the doors and windows close to the left side of the negative pressure fan are kept closed, forcing air to flow into the workshop by compensating the doors and windows on the side of the intake port. The air flows into the workshop in line and in sequence from the intake port, flows through the workshop, and is discharged from the workshop by the negative pressure fan. The ventilation is thorough and efficient, and the ventilation rate can be as high as about 99%.
  经过这样的原理,配上依据需求设计换气速度微风速的设计、让车间高热、有害气体、粉尘烟雾均能疾速排出车间,通风不良问题均能一次性彻底处理。从开启风机的几秒钟内即可到达通风的效果。
  Through this principle, with the design of ventilation speed and breeze speed according to demand, the workshop can rapidly discharge high heat, harmful gases, dust and smoke, and the problem of poor ventilation can be thoroughly dealt with at one time. Ventilation can be achieved within seconds of opening the fan.

  一、换气降温:由于阳光映照建筑物、机器设备、人体等热源招致需求通风的场所气温高于室外。负压风机能将室内热气疾速排出,让室温和外界温度持平,不至于车间内温度不流通持续升高。
  1. Air exchange and cooling: The temperature of places requiring ventilation is higher than that of outdoors because of the heat sources such as buildings, machinery and equipment, human body, etc. which are reflected by sunlight. Negative-pressure fan can expel the hot air from the room rapidly, so that the room temperature and the outside temperature are equal, so as not to keep the temperature in the workshop from rising continuously.
  二、空气活动带走人体热量,空气活动加速汗液蒸发而吸收人体热量,从而让人体觉得凉快,和自然风一样凉快。
  2. Air activity takes away human heat. Air activity accelerates sweat evaporation and absorbs human heat, which makes the human body feel cool, as cool as natural wind.
  三、负压风机只要通风降温的作用,没有制冷的功用,对人体安康无伤害,安康环保。
  3. As long as the negative pressure fan has the function of ventilation and cooling, it has no function of refrigeration, and does no harm to human health, health and environmental protection.
  负压风机假如能配合降温湿帘运用的话,在夏季最酷热的时分可将车间内温度控制在28摄氏度左右。但人体的凉快觉得可与空调相比,由于采取的是自然风,稍长时间对着水帘的人会觉得神清气爽不易疲倦。
  If the negative pressure fan can cooperate with the cooling and wet curtain, the temperature in the workshop can be controlled at about 28 degrees Celsius at the hottest time in summer. But the cooling of the human body can be compared with air conditioning. Because of the natural wind, people facing the water curtain for a long time will feel refreshed and not tired.
