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.

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.

The air cooler has a unique role in the preservation process of food. During the harvesting season of agricultural products, the indoor temperature is relatively high, and the temperature difference between day and night is relatively large, which is not conducive to fresh storage. The easiest way to face this situation is to find a place where the temperature is stable and cool to preserve agricultural products, such as caves, caves, cellars, etc., but these methods cannot control the temperature arbitrarily, the freshness is not enough, and the shelf life is also short. ,Time-consuming. If you really want to save agricultural products for a long time, the best solution is to create a controllable low-temperature environment by hand. The Beidou air cooler has an absolute advantage in refrigeration.

Beidou air-conditioner replaces traditional refrigeration materials with water--Freon as a refrigerant, using high-efficiency "water evaporation" cooling technology, using cooling water to contact with air, utilizing the characteristics of water absorption during evaporation to make indoor air The temperature (dry bulb temperature) is lowered. The detailed process is as follows: the outdoor humid fresh air passes through the cooling core component of the cooling fan, and exchanges temperature with the cooling water. Through the heat transfer, the temperature of the indoor air can finally drop to the temperature of the wet bulb. Moreover, when the air cooler is working, it can perform air freshness conversion indoors and outdoors, and can keep fresh and moisturize for a longer period of time.

Centrifugal fan is a disorderly equipment, mainly composed of air inlet, damper, impeller, electromechanical and air outlet. In the different state, the influence of the centrifugal fan is not the same. Therefore, some different operating conditions are not the same, and the influence of the centrifugal fan will be affected. Debugging the centrifugal fan to its optimum state can be used in many ways.

1. The centrifugal fan allows full-voltage starting or step-down electric, but it should be stable. The current at the full-voltage starting is about 5-7 times the extra current. The step-down starting torque is proportional to the square of the voltage. When the grid capacity is lacking. , should use the buck start.

2. When the centrifugal fan is in the test run, it should read the commodity imitation list and check whether the wiring method is consistent with the wiring diagram; it should be checked whether the power supply voltage supplied to the fan power supply is in compliance with the request, whether the power supply is phase loss or phase. Whether the capacity of the electrical components is in compliance with the request.

3. The number of people in the test is not less than two. One person controls the power supply. One person inquires about the state of the wind turbine. The invention is very weather-stop and immediately shut down. Check whether the twisting bias is accurate. When the centrifugal fan starts to start, check the various things immediately. Whether the current is equalized, whether the current is beyond the extra current; if there is no abnormal weather, it should be stopped for inspection. After five minutes of things, stop the machine to check if the fan is very meteorologically.

4. When testing the two-speed centrifugal fan, start the low speed first and check whether the torsional deflection is accurate. When starting the high speed, it is necessary to mobilize after the end of the fan to prevent the high speed reverse torsion, causing the switch to trip and the electromechanical damage.

5. When the centrifugal fan reaches the abnormal speed, it should measure whether the output current of the fan is abnormal. The running current of the centrifugal fan can't exceed its extra current. If the operating current exceeds its extra current, check if the supplied voltage is abnormal.

6. The electromechanical power required for the centrifugal fan means that under certain working conditions, the power required for the centrifugal fan breeze chassis and the air inlet is fully open. If the air inlet is fully open to stop things, there is a danger of damage to the electromechanical device. When the wind turbine is tested, it is best to close the valve at the inlet of the fan or the inlet pipe. After that, the valve will be drooped to open the hole to reach the end of the required working condition, and whether the current of the fan is exceeded.

For large industrial fans, because it is one of the website products and keywords, it is important to learn and understand, so that the importance of the product can be reflected. Moreover, since the website product is mentioned, it is better to continue to carry out its learning work, so that everyone can gain something and improve on their learning path.

    1. Large industrial fan, is it suitable for factory or home use?

    Large industrial fan, which is one of the industrial fans, whose main feature is the large power and air volume. However, for safety reasons, the use in the factory is more suitable, and it is not suitable for use in the home. Moreover, this conclusion can also be drawn from its name. So, on this question, the answer is for the factory.

    2. Is the tin factory suitable for large industrial fans?

    This is to look at the specific situation, mainly for the height of the iron factory, if it is high enough, you can use a large industrial fan, and vice versa. Generally speaking, the height of the factory is a limit of 5.5 meters. If it is between 5.5 and 18 meters, it can be installed and used. If it is below 5.5 meters, it will not work.

    3. How to detect the quality of large industrial fans?

    If this is done, it can be done by a multimeter. Using the resistance file of the multimeter, the resistance between the two red wires is detected. If the resistance is tens to 100 ohms, then the industrial fan is Ok. In addition, look at the short circuit between the winding and the housing.

     All of these are about large industrial fans, and at the same time, we must know and master everything, because only in this way can we make our own achievements, not nothing. Moreover, this is also a very good learning opportunity, so everyone should take good care of it, instead of wasting it, so as not to leave regrets.
