The air exchange efficiency of the air cooler is directly related to the convex surface of the diaphragm. Because of the irregular flow field of the convexity, the influence of the change of the wind changes. The vortex in the flow field from the convex cross section is not lost. In order to change the size of the partition, the height of the partition can be adjusted to prevent it. The wind structure of the cooling fan will affect the horizontal use effect, and the flow field in the axial and radial uniformity is destroyed, which will cause the unsteady flow phenomenon, which indirectly affects the stability of the insurance component.

  

   In the use of air coolers, air exchange efficiency is very important, not only can promote the effect of the cold air machine, but also the cost of the machine using the chiller to bring the economic cost of change to the user. Therefore, in order to improve the role of the air cooler to reduce costs, it is necessary to ventilate the machine of the cold air, improve the air cooler ventilation efficiency as much as possible to allow for a better air cooler.

   All in all, the efficiency of the use of chillers, in addition to these factors, the model of the chiller must be understood. The efficiency of air cooling is different, which requires the user to choose a suitable method to improve the overall efficiency of the air cooler.

Installing a chiller can help a person's health and reduce air temperature and air flow. Usually, the indoor temperature is about 8 degrees lower than the natural temperature, so that people are in the most comfortable and healthy environment, giving people a refreshing cool breeze in the hot summer. But many friends will ask if the air cooler can be combined with the air conditioner?

At present, many old office places are mostly equipped with air conditioners, but the temperature of the central air conditioner is too low, and the air will not be smooth. In the long run, it is not good for people's health. And because the cooling fan avoids this shortcoming and has excellent characteristics, many new office buildings have selected the cooling fan as an essential equipment. Because the water air conditioner can replenish fresh air in time, and the central air conditioner can replenish the air conditioner in time, I believe that the combination of the two will be more perfect.

For example, in the summer of Xinjiang, the outlet temperature of the chiller can reach below 20 °C, which can be applied to almost all occasions including hotels and hospitals. Then, in the southern region, places where chillers cannot be used alone, such as hotels, high-end office buildings, high-end and enjoyment-type places, and factories with strict requirements on humidity, can be used in conjunction with environmentally-friendly air conditioners when using split air conditioners or central air conditioners. It will not only save energy consumption in air conditioning, but also improve indoor air quality.

When the fresh air blower is used alone, the number of air changes is about 40 times. However, if it is used in combination with the central air conditioner of the split air conditioner, the number of air changes is usually 10-20 times.

As a kind of cooling equipment for cooling and ventilation, the air cooler is widely used in the enterprise workshop. Now the use field is gradually expanded to the greenhouse to cool down, and some public places are used for ventilation and ventilation. Some small models of household air coolers are suitable for summer and autumn. Seasonal household refrigeration and ventilation use, the following to understand the advantages of the lower cooling fan in the refrigeration industry. Ningbo City Air Cooler, Ningbo Air Cooler

  

1. The power consumption is low. The power consumption of the air cooler in the unit time is only one-fifth of that of the traditional air conditioner, which greatly saves the operating cost of the enterprise factory;

  

2, through the wet curtain for heat exchange and refrigeration, does not require the most refrigerated medium of Freon, safe and environmentally friendly in use;

  

3, the cooling speed of the rapid cooling effect is significant, in the relatively humid areas can reach 5-10 degrees Celsius cooling effect, in the hot and dry areas of the north can reach 10-18 degrees Celsius cooling effect;

  

4. The air cooler not only cools down but also can ventilate the indoor air. Keeping the air clean and dry for a long time, it will not produce the air conditioning disease of the traditional air conditioner, and it has no harmful feeling to the human body;

  

5. During operation, the vibration amplitude is small, the noise is low, and the air volume is large, which is suitable for the cooling of large workshops;

  

6. The operation interface of the air cooler is displayed by the LCD screen and has the function of time switch.

Negative pressure fan ventilation principle:

    The negative pressure fan and the environmentally-friendly air conditioner discharge air outward to lower the indoor air pressure, and the indoor air becomes thinner, forming a negative pressure zone, and the air flows into the room due to the air pressure difference. In the practical application of industrial plants, the negative pressure fan is concentrated on one side of the plant, the air inlet is on the other side of the plant, and the air is convectively blown from the air inlet to the negative pressure fan. In this process, the doors and windows adjacent to the negative pressure fan are kept closed, and the air is forced to flow into the workshop by the door and window on the side of the air inlet. The air is lined up in an orderly flow from the air inlet to the workshop, flowing through the workshop, and discharged from the workshop by a negative pressure fan. The ventilation is complete and efficient, and the ventilation rate can be as high as 99%. After detailed engineering design, designing ventilation speed and wind speed according to requirements, any high heat, harmful gas, dust and smoke can be quickly discharged into the workshop, and any problem of poor ventilation can be completely solved at one time. The ventilation effect can be reached within a few seconds from the opening of the fan. Ningbo City Air Cooler, Ningbo Air Cooler

Negative pressure fan cooling principle:

    First, ventilation and cooling: Because the sun shines on buildings, machinery and equipment, human body and other heat sources, the temperature is higher than the outdoor. The negative pressure fan can discharge the indoor hot air agilely, so that the ambient temperature at room temperature is equal, and the temperature in the workshop is not increased.

    Second, the air activity takes away the body heat, the air activity accelerates the transpiration of the sweat and absorbs the body heat, and then the body feels cool, and the natural wind is as cool as the natural wind.

    Third, the negative pressure fan only has the effect of cooling and cooling, there is no function of refrigeration, cool is the human body's feelings. The argument that the negative pressure fan can drop the temperature is unscientific.

    Fourth, in cooperation with the water curtain, the temperature in the workshop can be controlled within 28 degrees Celsius during the hottest hours in summer. However, the cool feeling of the human body can be compared with the air conditioner. Those who are facing the water curtain for a long time will feel cold and can't stand it.
