The importance of negative pressure centrifugal fan. Basic elements of negative pressure ventilation: It is to assemble a negative pressure centrifugal fan at one end of an independent space, which may be able to provide external ventilation system equipment. Aluminum alloy doors and windows are opened at the front or far side of the centrifugal fan as the air inlet, allowing air to circulate in the positive direction of the fire exhaust fan, and allowing the gas in this area to undergo convective heat transfer. This is called negative pressure ventilation—— In short, discharging is negative pressure ventilation.

Importance of negative wind pressure equipment

(1) Immediately remove excessive heat generated in the workshop;

(2) Immediately remove industrial waste gas and odors from the workshop;

(3) Immediately remove smoke and dust from the workshop;

(4) Immediately remove excessive moisture from the workshop to reduce discomfort with corrosion management methods for equipment;

(5) Improve the oxygen content in the workshop, enhance work efficiency and production capacity;

(6) Ventilation in the room can prevent the gathering of influenza viruses.

Nowadays, there are more and more users who use cold air fans for natural ventilation and cooling in factory workshops. Everyone highly recognizes the quality and actual effects of their products. Some new friends want to assemble, but they are concerned about the effectiveness of the machine equipment. We can understand this concern. In the end, some customers may not be very familiar with it, and may only have heard of it. Therefore, it is better to give it a try after hearing a lot, Today, the editor will talk to you about the advantages of air coolers!

1. Immediately remove excess heat from the workshop;

2. Immediately remove organic waste gases and odors;

3. Immediately remove thick smoke and dust;

4. Immediately remove too much moisture to reduce erosion of machinery and equipment;

5. Improve the oxygen content in the workshop, enhance efficiency and production capacity;

6. Indoor ventilation to reduce discomfort for relevant personnel.

Because the air cooler uses water evaporation to cool down, it can reduce the temperature by 4-10 degrees during hot summers. In extremely hot and dry climates, it can drop to over 15 degrees. When air enters the air cooler from the cooling water curtain, the water on top of the cooling water curtain evaporates and absorbs heat, producing strong cold air that is sent to the workshop for cooling. Therefore, it will change with external temperature changes, and the larger the external temperature, the greater the temperature, The better its actual cooling effect. It is worth mentioning that Yaoxian Industrial produces air coolers that are very energy-efficient, requiring only 1 kWh of electricity per hour to cool the total area of 100-150 square meters, which is very green and environmentally friendly. Because there is no refrigeration compressor, physical methods are directly used for cooling, making it completely green and pollution-free.

There are generally several types of roof fans commonly seen in the market nowadays, and the types are good for statistical analysis. This type of fan is installed on the roof, so it has the advantage of saving indoor space compared to some fans assembled indoors. But no matter what kind of machinery and equipment, there will also be some difficulties. If the temperature of the roof fan is too high, what is usually the cause?

When the roof fan operates at room temperature, there may be some phenomenon of high temperature, but it is only within the normal range. This is because the parts of the machine itself rub against each other, generating heat and causing the overall body temperature to be high. However, not all situations where the temperature is too high are normal. The main factors that cause the body temperature of the fan equipment to exceed the standard value are as follows:

The first type: motor phase failure or incorrect wiring.

The second type: excessive friction resistance in the system software or unscientific selection of fans can cause the motor to operate under overload, mainly due to excessive resistance coefficient in the pipeline network or failure to open the pipeline index gate valve.

The third type: low pressure of switch mode power supply.

Fourth type: Damaged motor bearings with small assembly clearance that does not comply with regulations.

Summer has arrived, and the annual hot weather has reappeared. I believe everyone is trying to find a way to relieve the heat, either by using fans, central air conditioning, or air coolers.

Air conditioning fans, in simple terms, combine the advantages of central air conditioning and electric fans. For example, central air conditioning produces equipment air and needs to be in a closed environment, which can easily cause discomfort. Although an electric fan is used for blowing, if the surrounding environment is very dirty, the wind blown out will also be very dirty. Most air conditioning fans have a dust removal mesh that can filter the air. If there is a layer of nano photocatalyst on the mesh for dust removal, it can also have a sterilizing effect.

When the air conditioning fan is turned on for cooling, it only consumes 60-80W, just like a refrigerator, which is why it consumes electricity.

The air conditioner, also known as the cooling water curtain air conditioner, is known for its environmental protection and mobile environmental protection. It is composed of a special corrugated honeycomb shaped wet curtain paper with a very large area, high-efficiency energy-saving fan, circulating water system, float switch water replenishment and moisturizing device, shell and electrical components, etc. It is also known as the cooling water curtain air conditioner, and is famous for its energy-saving and environmental protection; In the East China region, air conditioners use water to evaporate and absorb heat from the hot air, which in physics is called evaporative cooling. It is widely used in our daily lives, and when we stand by the sea, we feel very cool. When water is applied to the surface of the skin, the wind blows and it feels very cool. The East China region air conditioners use this weather phenomenon to combine intelligent and immediate evaporative cooling technology, and develop air conditioners (mobile environmentally friendly air conditioners or refrigeration units) that integrate cooling, ventilation, environmental protection, energy conservation, and environmental protection. Many years ago, it was widely used in Europe, foreign countries, and Middle Eastern countries. It has been 10 years since it entered China. Currently, China's production technology and processing technology are already very complete. It is more energy-efficient than central air conditioning, has a wide range of available options, and has good cooling effects, so it is being accepted by more and more entrepreneurial enterprises. At present, the overall market development trend is excellent, with prices ranging from over 1000 to 7000 to 8000 yuan per unit, most of which can meet the application requirements of each level. If manufacturers can provide good after-sales maintenance services, there should be no problem with short-term applications, but there is a significant difference in reliability and service life, which is mainly determined by the selected components and the technical level of the manufacturer. In addition, the attitude of the operator is also a decisive factor.
