Differences between industrial large fans and negative pressure fans

1. Different assembly

(1) Installation of industrial large fans. Industrial large fans are generally installed above industrial factories and their workshops, which have a wide range of work and can provide cooling for a large part of the area.

(2) Installation of negative pressure fan. Negative pressure fans are generally installed outside the workshop window and at the lower air outlet for convenient external ventilation.

2. The principle is different

(1) The principle of industrial large fans. The cooling principle of industrial large fans is that the cyclone forms a conical shape from top to bottom and promotes towards the road surface, with vertical flow on the ground. When encountering a horizontal cyclone that is isolated on the side or adjacent to the fan, it promotes upward to the flat roof, achieving effective overall ventilation for tall spaces and reasonable cooling for staff. Unclosed spaces with low environmental requirements can also be cooled reasonably.

(2) The working principle of negative pressure fan. Quickly achieve a larger exhaust volume when the fan is plugged in for operation. It can quickly create an air pressure difference between the indoor living environment and the outdoor environment, forming a strong negative pressure, driving dirty and hot gases in the room to be quickly discharged from the outdoor according to the flow direction set by everyone, and reducing the standard air pressure in the room.

3. Different efficacy effects

(1) The actual effect of industrial large fans. At the level of personnel cooling. The natural wind generated by a large energy-saving fan gently blows on the body, promoting the evaporation of sweat to carry away heat, and cooling the body, generating a cooling experience. Generally, this type of cooling experience can reach 5-8 ℃. In terms of air circulation, industrial large fans can accelerate indoor air flow and achieve air circulation effects; In terms of dehumidification and dehumidification, the dehumidification effect of industrial large fans is immediate and effective, as they promote the mixing of gases throughout the room.

(2) Actual effect of negative pressure fan. Due to the sunlight shining on buildings, mechanical equipment, bodies, and other heat sources, it is necessary to ventilate the site at a temperature higher than outdoors. The negative pressure fan can quickly exhaust the indoor heat flow, making the indoor temperature similar to the external environment temperature and preventing the temperature inside the workshop from rising. The negative pressure fan only has the effect of natural ventilation and cooling, and does not have the effect of cooling. Cooling is what the human body feels.

4. Different places of use

(1) Places where industrial large fans are used. Large public buildings such as shopping malls, sports venues, subway stations, airports, etc. promote indoor ventilation, eliminate odors, create a comfortable shopping and natural environment, and increase total sales. And the movable fan in the industrial fan can be used in relatively wide areas, which is also very convenient to use.

(2) Place where negative pressure fans are used. For example, clothing factories, hardware factories, leisure and entertainment clubs, breeding farms, garden flowers, etc

The demand for air conditioning fans in the Ningbo market has always been very high, and they play an important role in the market. What should air conditioning fan manufacturers pay attention to in ensuring after-sales service?

1. Transportation

Due to the large size of the air conditioning fan in terms of external dimensions, it is necessary for air conditioning fan manufacturers to pay attention to transportation and provide users with comprehensive transportation. During transportation, attention should be paid to the preparation of waterproof canvas and its packaging in advance to ensure the safety and efficiency of the air conditioning fan during transportation.

2. Installation

The installation of air conditioning fans requires professional personnel, and the attention of air conditioning fan manufacturers during installation is also necessary. Professional personnel should be prepared for installation to ensure the quality of air conditioning fans.

3. Maintenance

Air conditioning fans have their own warranty period, and air conditioning fan manufacturers should pay attention to the protection requirements in after-sales service. During the maintenance process of air conditioning fans, attention should be paid to repair, replacement, and compensation to ensure that the air conditioning fans are used normally and meet the requirements of the application.

Overall, the guarantee of air conditioning fan manufacturers in after-sales service requires attention to these aspects. In order to improve the reputation of the manufacturer, it is particularly important to enhance their reputation.

Water cooled environmentally friendly air conditioning has a wide range of main uses. During the process of using water-cooled eco-friendly air conditioners, some customers have noticed that water-cooled eco-friendly air conditioners may leak water. The main reason for water leakage may not necessarily be product quality issues. The problem of water leakage should be promptly inspected and resolved. Why do water-cooled environmentally friendly air conditioners leak water?

Difficulties in the drainage pipes of water-cooled and environmentally friendly air conditioners: It is necessary to inspect and clean the outdoor drainage pipes of water-cooled and environmentally friendly air conditioners. If the drainage outlet is blocked or blocked by dirt, it will not be able to drain, leading to water leakage. In addition, if the drainage pipe itself has many problems such as aging, bending, and looseness, it can also lead to abnormal drainage and leakage.

Difficulties in assembling water-cooled and environmentally friendly air conditioning equipment: Improper installation of water-cooled and environmentally friendly air conditioning equipment, vertical deviation, high joint orientation, and various factors can also lead to drainage blockage and leakage. The main reason for this situation may also be due to loose installation methods, weak positioning plates, and long-term displacement, which can cause the drainage side to be too high, causing drainage confusion and leakage, and should be dealt with in a timely manner.

The problem of water cooled environmental friendly air conditioning cooling water curtain: Water seepage is more common in water cooled environmental friendly air conditioning cooling water curtain. The long-term failure to clean the surface of the water cooled environmental friendly air conditioning cooling water curtain results in serious accumulation of smoke and dust, obstructed condensation water flow, and leakage of refrigerant in the refrigeration unit pipeline, resulting in partial freezing of the internal structure of the heat exchanger and water leakage.

In addition, due to poor quality of water cooled and environmentally friendly air conditioning insulation pipes or incomplete packaging, the pipes may also push dew droplets, leading to water leakage. In fact, this condition can avoid regular maintenance and upkeep in daily use, and regular maintenance and upkeep can also improve the use of water-cooled environmentally friendly air conditioners

How can energy-saving and environmentally friendly air conditioners solve the problem of cooling and ventilation in workshops? Due to the widespread popularity of energy-saving and environmentally friendly air conditioning equipment, more and more factories and workshops are reducing costs to overcome ventilation and cooling problems, which has been favored by many companies. The functional loss of energy-saving and environmentally friendly air conditioning equipment is not too high, but the actual cooling effect can reach the effect that traditional household central air conditioning cannot achieve. In terms of the cost of energy-saving and environmentally friendly air conditioning equipment, energy-saving and environmentally friendly air conditioning equipment is also the best cooling machine equipment.

In addition to the key ventilation and cooling of energy-saving and environmentally friendly air conditioning equipment, gas pressure can also be used to exhaust the factory's turbid air and hot air outdoors, followed by introducing fresh air, and then blowing in subtropical evaporation through water curtains to achieve ventilation, cooling, and odor removal effects. The use of traditional central air conditioning for cooling requires a sealed structure. It can indeed bring good cooling effects for a period of time, but over time, it will increase the turbidity in the air, which can be harmful to the health of employees working in the factory workshop. Relatively speaking, the actual ventilation effect brought by energy-saving and environmentally friendly air conditioning equipment cooling methods is conducive to solving this problem.

When dealing with the issue of ventilation and cooling in the workshop, water is used as the material, and a certain amount of environmental humidity needs to be brought during the cooling process. This moderate environmental humidity will give the human body a more comfortable feeling and is less likely to cause harm. However, due to temperature difficulties, energy-saving and environmentally friendly air conditioners need to be installed in factories and workshops, and there are certain requirements for relative humidity. Some factories are always worried that the products will be dry and cause damage to the products, and energy-saving and environmentally friendly air conditioners can also play a certain regulatory role.
