What does the meaning of air cooler have
   The application scope of air cooler is very wide, widely applicable to workshops, factories, Internet cafes and other places in all walks of life. Cooling fan running at work, outdoor hot air through the filter unit, and then after wet shelter, cooling and oxygen is high, the strong cold air flow through the duct to the workshop, workshop space pure and fresh, ventilation cooling, air in air pressure increases the size of the old workshop through the doors and Windows, discharge, outdoor air in the workshop has air conditioning, About 20 times per hour or more of the overall ventilation of the workshop heat, dust, odor discharge, make the workshop air quality fresh, comfortable and achieve cooling effect.
    It is worth mentioning that the cooling effect of the air cooler is directly related to the air exchange rate. Compared with the traditional air conditioning, the air cooler has a very alternative unit, that is the air exchange rate. So does it mean that the larger the air exchange rate, the better? Of course not.
Different places, the amount of air change will certainly be different. In general, the required number of air changes is about 25-35 times per hour. The general place referred to here is the place where the flow of people is not very large and there is no heating equipment, such as the conference room. At this time, if you enlarge the number of air changes, it is a bit of a waste of suspicion. For crowded places, the required number of air changes is about 30 to 40 times per hour. If it is a production workshop with heating equipment, then how also need to have 50-60 times/hour air change.
    The energy-saving cold air machine mainly makes the air in the workshop timely update and conditioning to humidity, the improvement of air quality, and the human body can absorb fresh air in time. Thus determining human health. Let's start by understanding the sources of air pollution.
    Workshop air has two sources of pollution, it is people use carbon dioxide, from exhaled carbon dioxide concentration in the human body to nearly 40 times higher than the natural concentration in the atmosphere, when 0.2% of carbon dioxide concentration in the air, will constitute a harm to human body, the second pollution sources are machinery and equipment at work a smell to smell and the product itself, People have a kind of compliance with gas and smell fatigue phenomenon, living in the workshop for a long time, the indoor smell will not feel out, according to scientific experiments, in order to make the workshop gas does not exceed the degree of harm to human health, it is necessary to keep the workshop fresh air.
We use a 400 square workshop of 100 people to calculate, the general environment of the workshop requires air change 25-30 times/hour, and the crowded public places require air change 30-40 times/hour; In the humid southern region, the number of ventilation should be appropriately increased, while in the hot and dry northern region, the number of ventilation can be appropriately reduced. The air volume of the air cooler is 18000 cubic meters/hour, and the number of ventilation in the room (H-1)= the total air volume of the air cooler (m3/h)/[room area (㎡)× the height below the air supply port (m)]. (Usually the air nozzle will be two meters high, 400 square condition of the common configuration of cooling fan according to 150 square one, about three) H-1=[18000*3/ (400*2)] the result is 66 times/hour. This is enough to deal with the plant heat, smell, high temperature problems. Thus, the workshop environment is greatly improved, the enthusiasm of the staff is greatly increased, and the production efficiency of the staff is improved.
     Air cooler can solve the problems of sultry and peculiar smell for you. If you use fans and central air conditioning, it is impossible to solve this problem perfectly. Fan is short of refrigeration, ventilation and ventilation effect, is the wind blowing out hot, said the pack fan weather in the south is also can't do any improvement, with the high cost of central air conditioning costs, electricity is also a expensive digital, also cannot achieve the effect of ventilation and ventilation, because the central air conditioning is negative pressure, doors and Windows are closed. Air is not moving. So the cooling is fixed, but the smell is not. So no matter from which aspect to consider, the choice of energy-saving cooling fan is the most sensible.

Air is not moving. So the cooling is fixed, but the smell is not. So no matter from which aspect to consider, the choice of energy-saving cooling fan is the most sensible.

    Negative pressure fans and environmental protection air conditioners discharge air to make indoor air pressure drop, indoor air becomes thinner, forming a negative pressure area, air due to pressure difference compensation into the room. In the practical application of industrial plants, the negative pressure fan is installed on one side of the plant, and the air inlet is on the other side of the plant, and the air from the air inlet to the negative pressure fan forms a convection secondary wind. In this process, the doors and Windows close to the negative pressure fan are kept closed, and forced air is compensated by the door and window on one side of the air inlet into the workshop. The air is lined up and orderly from the air inlet into the workshop, flows through the workshop, and is discharged from the workshop by the negative pressure fan. Thorough and efficient ventilation, ventilation rate up to 99%. Through specific engineering design, according to the need to design ventilation speed and wind speed, any high heat, harmful gases, dust smoke dew can be quickly discharged from the workshop, any poor ventilation problems can be solved once and for all. Ventilation can be achieved within seconds of starting the fan.
Negative pressure fan cooling principle
    1. Ventilation and cooling: the air temperature in places requiring ventilation is higher than outdoor due to the sunlight shining on buildings, machinery and equipment, human body and other heat sources. The negative pressure fan can discharge the indoor hot air quickly, so that the room temperature and the outside temperature is flat, so as not to increase the temperature in the workshop.
   2.air flow takes away heat from the human body. Air flow accelerates the evaporation of sweat and absorbs heat from the human body, thus making the human body feel cool, just as cool as the natural wind.
   3. negative pressure fan only ventilation cooling function, no refrigeration function, cool is the feeling of the human body. It is unscientific to say how much temperature a negative pressure fan can drop.
   4. When used with water curtain, the temperature in the workshop can be controlled within 28 degrees Celsius in the hottest days of summer. But the cool feeling of the human body can be compared with air conditioning, slightly long time to the water curtain people will feel cold and can not stand.

Working efficiency of negative pressure fan

Negative pressure fan is the use of cooling principle, ventilation, smoke and odor exhaust equipment. How effective does it work? Let's take a look:
1. Improve indoor air
The addition of negative pressure fan can improve the indoor air quality, provide a comfortable working environment, can improve certain work efficiency. In some industries where fans are used, air pollution in factories can be caused, especially because of the special nature of production. Therefore, not only is the environmental quality relatively low, but in the long run, the health of employees will certainly suffer to some extent.
Therefore, the installation of negative pressure fan can improve the indoor ventilation effect to a certain extent and effectively protect the health of employees. It mainly uses some nozzles, mufflers and some fan body, as well as front and rear fluid. Streamline industrial fan is mainly used in the nozzle series, with very high efficiency and good performance. The equipment is not allowed to collide with other metal shops, but also to gently handle the stainless steel tube.
2, noise treatment
After some noise reduction, the negative pressure fan generally does not reach the corresponding national standards and national noise emission standards, so as to achieve the satisfaction of the owner. Of course, the working principle of this fan is to use the gas loss is low, and then the pressure is low. In general, the gas can be directly treated as an incompressible fluid, without considering the gas contraceptive changes. According to the principle that the corresponding kinetic energy can then be converted into potential energy, the gas is continuously accelerated by the high-speed rotating impeller, and then the flow kinetic energy is changed.
Negative pressure fan is generally installed outside the window of the workshop, choose the outlet for exhaust, extract odor gas, general chemical plant and other applications are more.
