Product characteristics and working principle of industrial air cooler

Cooler, through continuous learning, we have a preliminary understanding and understanding of it. Well, the industrial chiller in the chiller may not be familiar to everyone, so it is necessary to study, and at present, there are still many applications of this chiller. With a comprehensive understanding, we can make the best use of it without causing waste.

    Industrial cooler, from the perspective of industrial cooler manufacturers, is a very good environmental protection product, because it has no compressor, no refrigerant and no pollution, it can completely meet the green environmental protection standard. Moreover, compared with air conditioners, it can reduce the cost and reduce the occupied area, but it can achieve the same ventilation and cooling effects. Therefore, in terms of performance, industrial air coolers are slightly better.

    1.Working principle of industrial air cooler

    When an industrial air cooler works, air enters its interior, creating negative pressure. When the dry bulb temperature at the outlet of the cooler is lower than the outdoor dry bulb temperature, a temperature difference is formed. Moreover, the larger the temperature difference, the more obvious the cooling effect. Therefore, through the continuous introduction of air, the indoor air can maintain freshness, thereby achieving the purpose of ventilation.

    2. The main characteristics of industrial air coolers

    (1) It has a low operating cost and can save a lot of power compared with an air conditioner with a compressor, which only needs one-eighth to one-tenth of that.

    (2) The cooler has a good cooling effect, especially in hot and dry areas, and its cooling range can reach about 10 to 15 degrees Celsius, which can be said to be very obvious.

    (3) The industrial air cooler is easy to install and maintain, even if it is not a professional, it can perform its installation and other tasks.

    (4) This kind of air cooler has low noise and small vibration during operation. Relatively speaking, its operation is very stable and reliable. In addition, because its body does not dissipate heat to the surroundings, it does not increase air temperature, and it does not experience problems such as local overheating.

Notes and influencing factors on the cooling of negative pressure fans

In terms of the specific aspects involved in the negative pressure fan, its cooling can be said to be important, and it must be understood and mastered, otherwise our learning is incomplete. Therefore, since it has a certain degree of importance, it is not too late in the following, so let's do it well so that we can grasp it in time and use it reasonably for the benefit of ourselves.

    1.Notes on the cooling of negative pressure fans

    In terms of negative pressure fan cooling, for all of us, especially learners, we should know and master, mainly:

    (1) Check the opening and closing action of the regulating valve in the negative pressure fan and some other related valves, whether it is flexible and reliable, and whether the mark is clearly visible to avoid problems and cause adverse effects.

    (2) For each component on the negative pressure fan, a comprehensive inspection should be performed without any omissions, mainly to see if there are any abnormalities or problems, and whether the voltage and current of the fan are within the normal range and whether their fluctuations are Normal wait. Because if the above problems occur, it will affect the cooling effect of the negative pressure fan.

    (3) In the installation of the negative pressure fan, to be correct and in place, there must not be a slight deviation, so as not to affect its cooling effect.

    2. What are the relevant factors in the cooling of negative pressure fans?

    In terms of the cooling of the negative pressure fan, its related factors, through the working principle of the fan, it can be known that in the rotation speed, the number of impeller blades, the blade installation angle and the chord length, if they are well matched, then it can be The negative pressure fan has a good cooling effect. In addition, if the number of blades, the blade installation angle, and the blade section chord length are determined, then the speed can be determined to match it.

    In addition, it should be noted that under the given design technical parameters, the speed of the negative pressure fan should be the design speed. This is better, and it should avoid too large or too small problems, so as not to affect the negative pressure fan. The cooling effect affects the performance of the fan.

Advantages of negative pressure fan in industrial environment

We have encountered many customers who have installed a large number of axial fans in high temperature plants. But the workshop was still so stuffy, and there was still so much dust and odor. What is the reason? If everyone is standing next to the axis of the axial flow fan, you will not feel the airflow at all, although there is a lot of wind on the axis. His air flow is linear. It is rarely driven by the surrounding air. It's like a high pressure faucet spraying water, standing on the side of the stream, your body won't get wet.


    The negative pressure fan is different. The negative pressure fan is like a reverse sprayer. Its absorption of air is horn-shaped, not only driving the airflow of the fan axis, but the horn-shaped scrolling air from the fan outward. When we stand next to the axis of the fan, we also feel a strong air flow. Its characteristics determine the thoroughness and high efficiency of its exhaust.

    Another important point is that when installing a negative pressure fan, the wall on the side of the fan must be sealed. Especially there must be no gap around the fan. We often see many customers install many negative pressure fans by themselves, but the workshop is still very stuffy, so they judge that the negative pressure fans have no effect. I have seen many scenes, often a large window. After installing a fan, the sashes next to the fan are open. It is conceivable that a large amount of air is only circulated around the fan, and of course it cannot absorb the air in the distance of the workshop.

    The most ideal way to install a negative pressure fan is to close the wall on the side of the fan and the nearby doors and windows, and open the doors and windows on the opposite side of the fan to ensure that the air flows in a straight line.
