Industrial sector: escorting production

In the industrial field, various factory workshops are important application places for air coolers.

Textile factory

Textile factories need to maintain certain temperature and humidity conditions to ensure the quality of yarn and the smooth progress of the textile process. Air coolers can effectively reduce workshop temperatures and avoid the impact of high temperatures on textile equipment and raw materials. For example, high temperatures may cause yarn to become brittle and increase the rate of breakage, while air coolers maintain the temperature within a suitable range, ensuring efficient and stable textile production. At the same time, its good ventilation performance can also reduce the accumulation of flying flowers and dust in the workshop, improve the working environment, and protect the respiratory health of workers.

electronics factory

Electronic factories have stricter requirements for the production environment, not only to control temperature, but also to prevent static electricity generation. The air cooler reduces the possibility of static electricity generation by adjusting the temperature and increasing air humidity. A stable temperature and humidity environment is crucial for ensuring product quality in processes such as chip manufacturing and circuit board assembly. The use of air coolers can effectively reduce the heat generated by equipment operation and personnel activities in the workshop, creating ideal conditions for the production of precision electronic equipment.

a machinery plant

In a mechanical factory, a large amount of mechanical equipment generates a large amount of heat during operation, causing the workshop temperature to rise. The powerful cooling ability of air coolers can provide workers with a comfortable working environment and improve labor efficiency. Moreover, the ventilation function of the air cooler helps to dispel the oil stains, odors, and metal dust in the workshop, ensuring the health of workers and the normal operation of mechanical equipment.

Business field: Enhancing customer experience

Commercial places have extremely high requirements for environmental comfort, and air coolers play an important role in this regard.

Shopping malls and supermarkets


Shopping malls and supermarkets are densely populated places that require a cool and comfortable shopping environment. Air coolers can provide sufficient air conditioning for large business areas without taking up too much space. Its fresh air function can also effectively reduce odors, making customers feel physically and mentally happy during the shopping process. In addition, the relatively low energy consumption of air coolers also saves operating costs for businesses.

Restaurants and internet cafes

In restaurants, air coolers can create a comfortable dining environment. Diners will not feel uncomfortable due to high temperatures while enjoying delicious food. For places like internet cafes where people stay for long periods of time, air coolers can not only lower indoor temperatures, but also increase the oxygen content in the air, alleviate customer fatigue caused by prolonged use of computers, and enhance customer satisfaction and loyalty.

In the field of agriculture: supporting the growth of animals and plants

The application of air coolers in the agricultural field is also very extensive, creating favorable conditions for agricultural production.

Greenhouse

The temperature and humidity inside the greenhouse have a crucial impact on the growth and development of crops. Air coolers can lower the temperature inside greenhouses during high temperature periods during the day, preventing excessive temperature from causing damage to crops such as burning leaves and affecting flower bud differentiation. At the same time, it can also regulate the humidity inside the greenhouse, reduce the occurrence of pests and diseases, and improve the yield and quality of crops.

farm

In breeding farms, air coolers are of great significance for the healthy growth of livestock and poultry. High temperature environments can easily lead to heat stroke, decreased feed intake, and slow growth in livestock and poultry. Air coolers can effectively reduce the temperature inside the breeding house and improve the comfort of livestock and poultry. Moreover, the ventilation function of the air cooler can reduce the concentration of harmful gases such as ammonia and hydrogen sulfide in the house, lower the incidence of respiratory diseases in livestock and poultry, and ensure the efficiency of breeding.

Family Domain: Affordable Cooling Options

The application of air coolers in households is also becoming increasingly popular.

In living rooms or bedrooms, air coolers can be used as auxiliary cooling devices. Especially in some well ventilated houses or areas where the summer is not too hot, air coolers can meet people's need for coolness. It can adjust wind speed and temperature according to different usage scenarios, with simple and convenient operation. At the same time, the air cooler has the characteristic of increasing air humidity during operation, which can improve the indoor dry environment for households in dry areas and make residents feel more comfortable.

In short, with its unique advantages, air coolers have been widely used in various fields such as industry, commerce, agriculture, and households, becoming a powerful assistant in creating cool and comfortable environments.
Knowledge

The basic knowledge of installing negative pressure fan

 

When installing the negative pressure fan, the wall of the fan here must be treated with airtight. In particular, there can be no clearance around the fan. The ideal way to assemble the negative pressure fan is that the walls on one side of the fan and the surrounding Windows and doors are all closed, and the Windows and doors on the opposite wall of the fan are opened to ensure that the air flow is in a straight line.

The assembly of the negative pressure fan is a particularly key project. The actual effect of the use of the negative pressure fan in the future has a great impact. It must be paid attention to at all times in all links of the assembly.

Before the assembly

1. Before the assembly of the negative pressure fan, we should carefully check whether the negative pressure fan is intact, whether the fastener bolts are loose or fall off, and whether the impeller has knocked against the wind cover. Carefully check whether the fan blade or louver is deformed or damaged during transportation.

2. When selecting the air outlet environment for assembly, attention should be paid to the fact that there can be no large barrier within 2.5-3m directly opposite the air outlet.

When the assembly

1. Stable assembly: attention should be paid to the horizontal orientation of the negative pressure fan when it is assembled, and it should be adjusted to the level that the negative pressure fan is firm with the foundation plane. The motor should not be skewed after assembly.

2. When assembling the negative pressure fan, the control bolt of the motor should be located in the direction convenient for practical operation. In order to facilitate the use of the control belt tight loose.

3. When assembling the support frame of the negative pressure fan, make sure that the support frame is firmly horizontal with the ground plane. If necessary, assemble the Angle iron beside the negative pressure fan to take reinforcement.

4. After the assembly of the negative pressure fan, it is necessary to check the surrounding airtightness. If there is a gap, to use the sun plate or glass glue to take airtight.

After assembly

1. After the completion of assembly, check whether the inside of the negative pressure fan is left behind props and sundries. Rotate the fan blade by hand or lever to check whether it is too tight or brushed, and whether there is no guide that prevents the rotation of the object, before the test run can be taken.

2. If the vibration of the negative pressure fan or the abnormal sound of the "buzzing" of the motor is shown during operation, it should be shut down and checked, and then started for use after repair.

What are the differences between axial flow fan and negative pressure fan

What is a negative pressure fan?
A lot of people do not understand this concept, the following details of the negative pressure fan is what. The negative pressure fan in the air cooler is a kind of suction fan, because the working principle is to use negative pressure ventilation, the physical principle of air convection to force air convection ventilation and cooling, so it is called the negative pressure fan. Negative pressure fan is the best choice for ventilation and cooling, especially used in industrial plants, pig farms, chicken farms, greenhouses, Internet cafes and other places. Negative pressure fan is mainly used for the overall solution of high temperature, sultry, smoke, odor, dust and other poor ventilation problems. Negative pressure fan is low pressure fan. Negative pressure fan is commonly known as wet curtain fan, glass fiber reinforced plastic fan, galvanized sheet fan, iron fan, industrial fan, negative pressure exhaust fan, negative pressure ventilation fan, animal husbandry fan, etc.

One, the type of negative pressure fan:
Negative pressure fan this kind of product is various, mainly from the following aspects:
1, from the frame material distinction: FRP glass fiber (FRP), galvanized sheet, plastic steel;
Galvanized sheet negative pressure fan is made of galvanized iron sheet (commonly known as tin sheet). It is the most common negative pressure fan in the market. Because it is affordable, many manufacturers choose negative pressure fan made of this material. But the service life of this negative pressure fan is short;
FRP negative pressure fan:
FRP glass fiber negative pressure fan (FRP is fiber reinforced plastic) commonly known as FRP fan;
FRP features:
(1) light weight and high strength.
(2) good corrosion resistance. To the atmosphere, water and general concentration of acid, alkali, salt and a variety of oils and solvents have better resistance.
(3) Good electrical performance. Excellent insulating material, used to make insulators. Good dielectric protection at high frequencies. Microwave transmittance is good.
(4) good thermal performance. FRP has low thermal conductivity and is not easy to deform.
Because of the above characteristics of FRP, FRP negative pressure fan is high temperature resistant, acid and alkali resistant, light and stable, and has a longer service life.
Plastic steel negative pressure fan: rarely used on the market at present;

2. Transmission mode: the transmission mode of the negative pressure fan is divided into direct type and belt type.
From the perspective of this transmission mode, the transmission mode affects the air volume, noise, and maintenance of the negative pressure fan; Direct type is superior;
1. The blades of direct negative pressure fan are directly installed on the motor, which reduces the power loss caused by transmission. For fans with the same power, the air volume of direct negative pressure fan is about 10% larger than that of belt type. The belt of belt-type negative pressure fan will become loose after a long time, and the air volume of the fan will decrease significantly after loosening.
2. Direct negative pressure fan also has no noise caused by belt friction.
3. Belt type should be maintained. Generally, the negative pressure fan belt can be used for two years (imported) and a small amount can only be used for one year, especially the negative pressure fan installed at high altitude is also difficult to replace.


What is an axial fan
Axial flow fan is the air flow in the same direction as the axis of the blade (that is, the flow of the wind is parallel to the axis), such as electric fans, air conditioning fans are axial flow fans.

A common example of an axial fan is a typical bench type fan. It is called "axial flow" because the air passing through the fan does not change direction, but flows parallel to the fan axis. Axial fan is usually used in high flow requirements and low pressure requirements of the occasion.

Axial fan blades work in a similar way to the wings of an aircraft. But whereas the latter push lift up the wings and support the weight of the aircraft, the axial fan holds the air in place and moves it around.

The cross section of an axial fan is generally a wing section. The blade may be fixed in position or rotated about its longitudinal axis. The Angle of the blade to the airflow or the blade spacing may be unadjustable or adjustable. Changing blade angles or spacing is one of the main advantages of axial fan. Small blade spacing Angle produces lower flow rate, while increasing spacing produces higher flow rate.

Advanced axial fans can vary the blade spacing as the fan is running (much like a helicopter rotor), changing the flow rate accordingly. This is called a vane adjustable (VP) axial fan.

Axial flow fan, also called local fan, is a kind of fan commonly used in industrial and mining enterprises. Its motor and blade are in a cylinder, and the shape is a cylinder. It is used for local ventilation, convenient installation, obvious ventilation effect, safety, and can be connected to the air duct to send the air to the designated area.

What are the differences between axial fan and negative pressure fan
As we all know, there are a lot of high temperature factories are installed with a large number of axial flow fans, but the workshop is still so hot to the hopper, or so much dust and odor.
To the surrounding air.
An example shows that if you stand next to the axis of an axial fan, you will not feel the air flow at all, even though there is a lot of wind on the axis.
And suction fan is like a reverse atomizer, it is to absorb the air horn shaped, not only drives the fan axis of airflow, but by the fan in the outward show trumpet-shaped scroll air, we were standing next to the axis of the fan impeller to the powder machine will also feel a strong airflow, this feature determines its exhaust thoroughly with high efficiency.

Defrosting mode of industrial air cooler

Cooling fan of the over-current protection, it is a kind of protection mechanism of air cooler, showed that the current exceeds the provisions of the machinery, equipment, and equipment failure problems, then, should immediately stop the operation of the air cooler, and inspection work, in order to find out the problems and solve in time, so, to avoid adverse effects or consequences.

1. If the air cooler is divided into categories, then, what kinds can it have? Are they the same in the application domain?

If the type of air cooler is divided, then it can be divided into two kinds: refrigeration industrial air cooler and household air cooler. However, they are not the same in the field of application, because the former is in the cold storage, cold chain logistics and other refrigeration environment, while the latter is for household use. Therefore, the above conclusion. So, on question two, the answer is no.

2. Cold storage evaporator, which can be an air cooler?

Cold storage evaporator, it can be a cold fan, so in this question, its answer is yes, and it is beyond doubt. Its specific role is to low temperature and low pressure saturation refrigeration, gasification through heat exchange, and the heat in the cold storage away, so as to avoid its abnormal temperature. So, its role, or very important.

3. Is there a relationship between the air volume of the air cooler and the refrigeration effect? In addition, how to look at the power consumption of the air cooler?

There is no relationship between the air volume of the air cooler and the refrigeration effect, because the air volume of the air cooler is large or small, but in the refrigeration effect, it is the same, and there is no big difference. If you want to know the power consumption of the air cooler, it is to see the power size marked on the nameplate of the machine, so as to get the specific value, rather than the cooling capacity. So on this point, we should be clear.
