We all know that the current of the air cooler is several times of the budget quota when it is in operation. In this way, several runs will undoubtedly not only waste the excess electricity during its service period, so many air cooler manufacturers have optimized the air cooler. Let us understand next.

In equipment design, the selection of motors will have a certain capacity. Motor speed is fixed, but in specific use, it is sometimes necessary to operate at a relatively low or relatively high speed. Therefore, it is necessary to carry out frequency transformation. Variable frequency governor can change the input voltage frequency of the machine to achieve the soft start of the motor, environmental protection, energy saving and speed change, and the machine equipment to give over current, over voltage, load protection.

Large and medium-sized industrial air cooler application [tips] Large and medium-sized industrial air cooler manufacturers explain! Large and medium-sized industrial air coolers are generally used in factories and other locations, especially in summer. Standing on the roadside should also be able to feel the energy of large and medium-sized industrial air coolers. Although the application of large and medium-sized industrial air cooler is very helpful, there are still some problems that need to be paid attention to in the use of large and medium-sized industrial air cooler. Actually can master from six, follow the large and medium-sized industrial air cooler manufacturers to understand. Because of the complex application scenarios (most commonly seen in industrial plants), large and medium-sized industrial air coolers should be maintained to avoid some emergencies destroying the quality of centrifugal fans and harming the operation of large and medium-sized industrial air coolers. There are many small maintenance points for large and medium-sized industrial air coolers, which are summarized as follows:

1, each large and medium-sized industrial air cooler for 70-100 square meters of room temperature reduction. Beyond these values, the actual effect of large and medium-sized industrial air coolers is likely to be less than ideal, which is easy to cause too much work and problems of large and medium-sized industrial air coolers.

2. When large and medium-sized industrial air coolers are used, check whether there is paper debris, dust and other dirt in the wet curtain and the reservoir. Clean it 1-2 times a year.

3. Large and medium-sized industrial air cooler is the cardiovascular of cold fan. If there are common faults, the switching power supply of large and medium-sized industrial air coolers should be cut off immediately and welders should be arranged for immediate maintenance. Attention should be paid to wire joints when installing large and medium-sized industrial air coolers, and care should be taken when disassembling and installing centrifugal impellers of large and medium-sized industrial air coolers to prevent leaf deformation of large and medium-sized industrial air coolers from striking with the shell.

4. If the float switch of large and medium-sized industrial air cooler is ineffective, and it is found that there is less water or overflow water in the pool of large and medium-sized industrial air cooler, it should be corrected and replaced in time.

5, once found that large and medium-sized industrial wet curtain cooling fan power supply is not enough or not divide evenly, inspection of large and medium-sized industrial air cooler storage tank is less water, large and medium-sized industrial cooling fan pump operation, large and medium-sized industrial cooling fan flow pipe and pump channel is blocked, large and medium-sized industrial cooling fan spray nozzle head is located in the middle of the damp curtain. The relative height of normal sprinkling of large and medium-sized industrial air cooler can not be ignored. If the water level is too low, it is very easy to burn large and medium-sized industrial air cooler.

6, large and medium-sized industrial air cooler maintenance, power off, cut off large and medium-sized industrial air cooler switch power supply after a period of time, because the long-term use of large and medium-sized industrial air cooler will release static electricity, electrostatic induction is not easy to fade after power failure, so safety after maintenance. This is also the application of large and medium-sized industrial air cooler should pay attention to the six aspects. Friendship reminds us to be more careful in the use of large and medium-sized industrial air coolers, otherwise it will cause certain harm to their production activities, and may also affect the use period of large and medium-sized industrial air coolers. So that's what we have to watch out for.

Working principle of air cooler

The cooling principle of the air cooler (evaporative air conditioner) is: When the cold wind during into the cavity to produce negative pressure, make clear wet curtain air through the porous moist surface force of the curtain air dry bulb temperature dropped to close to the outside air wet bulb temperature, the cooling fan export the dry bulb temperature of 12 ℃ lower than outdoor dry bulb temperature of 5 - (dry areas can reach 15 ℃), the dry air, the temperature difference is big, the better the cooling effect. Because the air is always introduced into the room from the outside, (this time called positive pressure system) so it can keep the indoor air fresh; At the same time, because the machine uses the principle of evaporation and cooling, so it has the dual function of cooling and humidifying (relative humidity can reach about 75%), used in textile and knitting workshops, not only can improve the cooling and humidifying conditions, but also can purify the air, reduce the needle breaking rate in the process of knitting, improve the quality of needle textile products.

The air cooler (evaporative air conditioner) is surrounded by a honeycomb wet curtain using special materials, with a large surface area, through the water circulation system to constantly humidify the wet curtain; There is a high efficiency, low noise and energy saving fan in the wet curtain fan. When the fan is running, the negative pressure generated by the wet curtain fan makes the air outside the machine flow through the porous wet curtain into the machine. Because the evaporation of water on the wet curtain absorbs heat, the air through the wet curtain is forced to cool down. At THE SAME TIME, because THE water on the wet curtain evaporates to the air flowing through the wet curtain, increasing the humidity of the air, so the wet curtain cooler has the dual function of cooling and humidifying.

How about the cooling effect of the air cooler

It is understood that the air cooler can not be compared with the capacity of air conditioning refrigeration, but the price is lower. Compared with the price of 10%~20% of air conditioning, the power consumption is only about 2% of air conditioning, so it still attracts the favor of many consumers. In different regions of China, the use effect of air cooler is different, but the cooling effect is better than that of ordinary electric fan, and the reduction is at least 3~8℃. The hotter the weather, the more obvious the cooling effect, the greater the wind, the better the cooling effect.

Energy saving and environmental protection air cooler can bring a kind of fresh air for the workshop and public places of enterprises, as well as commercial entertainment and other places, and can completely reduce the temperature. This kind of product is characterized by no compressor, no refrigerant, no copper pipe, and its main core is evaporative wet curtain. The 1.1KW main motor used by this energy saving device can be said to be one eighth of the power consumption of the traditional central air conditioning, and its power saving effect can be said to be a must for enterprises.

The selection of the model of the cooling machine in the workshop is the necessary process for each cooling engineering project in the workshop. The selection of the appropriate cooling machine and equipment in the workshop is the most effective way to ensure the actual effect of the cooling engineering project in the workshop.
