For low-temperature cold storage or ultra-low temperature cold storage, we recommend using platoon pipes. Many low-temperature cold storages on the market use platoon tubes as external machines. From a long-term point of view, the use of pipes will ensure uniform cooling capacity in the cold storage, energy-saving and power-saving, but it also has shortcomings. The price is relatively high and it is inconvenient to install compared to air coolers.

   Of course, in general low-temperature cold storage at minus 18 degrees or minus 25 degrees, it is possible to use air coolers, and there is no need to worry about the problem of frosting, but if it is an ultra-low temperature cold storage, it is still recommended to use pipes. More than

1. From the perspective of cooling effect:

   The cooling effect of the pipe is slightly better than that of the air cooler. The heat conduction and cooling of the pipe is faster, especially with aluminum. Because the distribution of the pipes is relatively balanced, the cooling capacity is relatively uniform, which can achieve the effect of energy saving and power saving.

2. From the scope of application:

   Because the pipe is a pipeline evaporator, it can lock the moisture very strongly. Because the air cooler is blown by the wind, it will evaporate the water, making the products in the warehouse dry and withered. Therefore, the pipe is suitable for products with more moisture, such as Popsicle ice cream, fruits and vegetables, etc., and the air cooler is suitable for dry goods, dried fresh, frozen meat, etc. Therefore, generally choose to install the tube or the fan, mainly depends on which one is more compatible with your product.

3. From the height of the library body:

   If it is a large-scale cold storage, if the external height of the cold storage is relatively high, it is recommended to use a cooler for the internal machine. If the pipe is used, the installation is very inconvenient and there are hidden dangers. The air cooler is often used in high-rise warehouses because of its easy disassembly and assembly.

4. From the perspective of economic adaptation:

   Generally speaking, due to the cooling performance and production cost of the platoon, the price of the platoon is generally slightly higher than that of the air cooler, especially the aluminum platoon, but the long-term operation of the air cooler library consumes more power than the aluminum platoon tube library, so the specific use is The piping is still a fan, and it still depends on the budget.

As long as the environmental protection air conditioner (evaporative air cooler, water-cooled air conditioner) is maintained correctly, the service life will be longer and longer, and the effect of ventilation and cooling is also very good. So what points cause the frequent failure of industrial air coolers? How should we maintain it?

1. If the air pollution around the air cooler unit is large, the host should be cleaned once or twice a day to ensure that the air conditioner sent out is fresh and clean. It is recommended to use the automatic function mode to run.

2. The bottom basin and evaporation medium of the unit should be cleaned once after half a year of operation, and the water pressure should not be too high during cleaning to avoid damaging the wet curtain.

3. In order to prevent freezing damage to the machine body and mosquito breeding when it is not used for a long time, the water inlet valve of the tap water machine should be closed, and the unit should enter the cleaning mode, and the remaining water in the bottom basin of the water tank will be drained. Cover the dust net and lock it tightly to prevent the sandstorm from blocking the evaporation medium in late autumn and early winter.

4. When the air cooler unit is overhauled, it is necessary to turn off the power supply of the control box, and the maintenance personnel must hang up the maintenance card when in the machine and it is strictly prohibited to turn on the power.

5. When the air cooler unit trips due to a fault, it is necessary to remove the fault before pressing the air switch.

6. The smell of sawdust comes out after use, which disappears after 24 hours of continuous use.

7. Rain-proof blinds cannot be subjected to force. It is strictly forbidden to use the blinds as a stress point and move them by hand during installation or under such circumstances.

8. The memory battery should be replaced after two years.

9. The main frame should be treated with anti-corrosion and lacquer after two years. The firmness of the main frame should be checked regularly every year.

1. The fresh air coefficient is high and the air quality is good. When the traditional compressor air conditioner is running, the doors and windows need to be closed to keep the indoor temperature constant. Because the doors and windows are closed, there is less fresh air entering the room, the number of indoor air changes is low, and the air quality is poor. Dizziness, headache, and physical discomfort are caused; the indoor temperature in the production workshop of the enterprise is high in summer, and the air quality is poor, especially in the workshop that produces harmful gases. If closed cooling and ventilation are carried out, it may even cause poisoning, which will affect the human body and the production of the enterprise. Cause adverse effects. The core component of the evaporative air conditioner is the evaporative wet curtain, which is characterized by good water absorption and ventilation performance, strong texture, water immersion resistance without deformation, and corrosion resistance. By designing a special corrugated angle, the water can flow directly to the side where the air enters the wind. When fresh air passes through it, it can ensure that the water and the air are in full contact. This not only improves the evaporation efficiency, reduces the temperature, but also effectively filters out harmful substances and dust in the air. When the evaporative air conditioner is running, the doors and windows are opened (if there is an exhaust system, the doors and windows may not be opened.), there is no need to self-circulate the old indoor air, but always provide sufficient fresh and natural cold air. The fresh air coefficient is high and the air quality is good. The human body does not cause damage, which is conducive to normal production.


2. Energy-saving and environmental protection of workshop air coolers: Central air conditioning has a greater impact on the environment. For example, the chlorine ions in freon have a destructive effect on the ozone layer of the atmosphere. During operation, the condenser also continuously dissipates heat, while evaporative air conditioners The unit is an environmentally friendly product with no compressor, no refrigerant, and no pollution, and it does not dissipate heat to the surroundings. In terms of energy saving: in the same process conditions and air-conditioning area, central air-conditioning consumes a lot of energy and is wasteful; installing evaporative air-conditioning units can effectively save energy, and the power consumption of evaporative air-conditioning units is only that of central air-conditioning About 15-50%, this can not only reduce energy consumption for the enterprise, but also can actually save operating costs, but also save electricity and reduce the impact of power shortages on production and work.


3. Less investment and quicker results. In the same process conditions and air-conditioning area, the installation of traditional compressor-type central air-conditioning investment is large; and the total investment of installing evaporative air-conditioning units is less than the total investment of installing traditional compressor-type central air-conditioning 30 to 70%. In the same process conditions and air-conditioning area, the installation time of the evaporative cooling air-conditioning project is more than 50% less than that of the traditional compressor-type central air-conditioning, and the effect is quick.


4. Humidity adjustment When adjusting humidity in some dry rooms, or in some places that need to be humidified, traditional compressor air conditioners need corresponding humidity adjustment facilities; while evaporative air conditioners may not need humidity adjustment facilities, and the unit can Adjust the air humidity by itself to meet the needs of the production process.


5. Small footprint, simple and convenient installation. In the same process conditions and air-conditioning area, the installation of traditional compressor-type central air-conditioning requires a dedicated machine room, which covers a large area; while the evaporative air-conditioning unit is mainly installed on the roof and wall brackets The upper or indoor machine room occupies a small area, which is about 90% less than that of a traditional central air conditioner. Some evaporative air conditioners do not occupy any building space. The central air-conditioning system consists of chillers, cooling towers, cooling water pumps, terminal devices and other equipment, which is troublesome to install, while evaporative air-conditioning units do not require chillers, cooling towers, cooling water pumps, terminal devices and other equipment, so the system is easy to install Fast.


6. Stable performance, reliable quality and convenient maintenance. The traditional compressor-type central air conditioner has a complicated structure, requires professional operation and maintenance, and the maintenance cost is relatively high; the evaporative air conditioner unit is equipped with automatic electronic control and automatic cleaning functions , The equipment has stable performance, low noise, high efficiency, reliable product quality, convenient and simple operation and management, no professional operation, simple maintenance and low cost.
