How to choose the distance of the air cooler

People who use subcoolers know that the cooling effect of the cooler is very good, and its effect is comparable to that of air conditioners, and in terms of energy saving, it is more than a little bit stronger than air conditioners, so when many people choose refrigeration to stir up Air conditioners are often given priority. When selecting the air cooler, you need to choose the film spacing. Many people don't understand the selection of the film spacing. Let me introduce it to you below.
      Choice of air-cooler space
      Air cooler As the evaporator commonly used in refrigeration systems, its proper selection directly affects the efficiency of the refrigeration system. As we all know, the chiller will use different fin spacing according to the required ambient temperature. In our common air cooler, the fin spacing is 4mm, 4.5mm, 6 ~ 8mm, 10mm, 12mm, and there is a variable pitch between front and back. The fin spacing is small, suitable for high temperature environment; the lower the temperature of the cold storage, the larger the fin spacing required. If the selection is unreasonable, the fins will be frosted fast, and the wind passage will be blocked soon. It is difficult to cool the cold storage, and the efficiency of the compressor cannot be exerted, resulting in increased power consumption of the refrigeration system.
      According to engineering experience, generally 0 ℃ ~ 20 ℃ environment, such as workshop air conditioners, cool storage, cold storage wear hall, fresh storage, air conditioning storage, ripening storage, etc., choose the 4mm or 4.5mm air cooler; -16 ℃ In the environment of ~ -25 ℃, such as low-temperature freezing and refrigerating, low-temperature logistics warehouse, the air cooler with a slice distance of 6mm ~ 8mm is selected; and the quick-freezing warehouse of -25 ℃ ~ -35 ℃, generally use a cooler with a slice distance of 10mm and 12mm. If the fast-frozen cargo has high humidity, the variable blade is selected from the cooler, and the distance between the fins on the inlet side can reach 16mm.
      However, in some occasions, the fin pitch of the cooler cannot be selected based on temperature alone, such as rapid pre-cooling and acid removal of meat and vegetables. Although the temperature of the cold room is generally set above 0 ° C because of the high incoming temperature and cooling Fast speed and high humidity of the goods. If the air cooler with 4mm or 4.5mm space is used, it is not suitable. It is necessary to use an air cooler with 8mm or even 10mm space.
      There is also a fresh-keeping store similar to the storage of fruits and vegetables such as garlic and apples. The suitable storage temperature is generally -2 ° C. Such a fresh-keeping or modified atmosphere store with a storage temperature below 0 ° C also requires the use of cold air at a distance of not less than 8mm. Machine to avoid rapid air-frosting that can cause blockage of the air duct and increase power consumption.

Five characteristics of industrial air coolers and installation instructions

    Among the environmental protection products, the industrial air cooler can be regarded as one, and its use is similar to that of ordinary air coolers, which are used to achieve the purpose of ventilation and cooling. Then, through different aspects, we have a preliminary familiarity and understanding of the industrial air cooler, in order to distinguish it from the ordinary air cooler.

    Why is the industrial air cooler an environmentally friendly product? This is because such a chiller does not have a compressor and a refrigerant, and does not cause environmental pollution. Therefore, this chiller is classified into the environmental protection category. In principle, the method of convection ventilation is used to ventilate and cool the room to achieve the desired temperature and humidity.

1. The main characteristics of industrial air coolers
    (1) It can be green and environmentally friendly, and it hardly pollutes the ambient air. In addition, the cooling effect is very obvious. For different regions, there can be a suitable cooling range to stabilize the temperature.
    (2) From the perspective of its operating costs and investment benefits, industrial coolers are also very good, with better investment recovery and lower operating costs.
    (3) Compared with the traditional air-conditioning system, the cost can be effectively reduced, and some can be reduced to less than half.
    (4) The industrial chiller is simple and convenient to operate, requires little maintenance and is easy to carry out. No professional maintenance and repair personnel are needed, and some simple problems can be handled.
    (5) During the operation of the industrial air cooler, the noise and vibration are small, and the body itself will not dissipate heat to the surroundings, which can avoid overheating.

2.Instructions for the installation of industrial air coolers
    Generally speaking, it is better to install industrial air coolers outdoors. If the ambient air quality is good, it will be of great benefit to it. However, it cannot use the return air method because problems may occur. For the air ducts, it should be avoided to be too long, it is better to control it to 15-20 meters. The use of elbows should be minimized or even not used.

    Through the above two parts, we can clearly know what the characteristics of the industrial air cooler and some must-know contents on the installation, so that it can be used in actual operation to improve its performance and effect. From another perspective, these are also necessary prerequisites and preparations for in-depth discussion.

How to identify the performance of negative pressure fans? How to solve the noise?

Negative pressure fans believe that everyone has heard of it, it is the main cooling equipment in many factories, workshops, farms and other places. How to identify the performance of the negative pressure fan? And the mechanical equipment will inevitably produce a certain noise during the use of the process, how to solve the noise of the negative pressure fan? Today we will look at it together.

How to identify the performance of negative pressure fans?
1. To ensure dynamic balance. As we all know, dynamic balance is the basis for ensuring the effective operation of negative pressure fans. The negative pressure fan with good quality and excellent quality has low vibration and low noise during operation, which can greatly improve the working efficiency of the negative pressure fan.
2. In the treatment of noise, the enterprise can judge the noise by changing the sound during the working process of the negative pressure fan.
3. When observing the air volume of the negative pressure fan, it can be judged by observing the condition of the blade of the front louver during operation and the wind pressure when the negative pressure fan is working.
4. Determine whether the negative pressure fan meets the technical requirements by measuring the current.
How to solve the noise of the negative pressure fan?
1. When the negative pressure fan is installed, the contact with the window frame is too tight, so that the window frame resonance occurs when the negative pressure fan is running.
Solution: Reduce the packing between the window frame and the water air conditioner properly, and use a softer material to fill it. If the bottom of the installation is not stable, the bottom plate should be stabilized and placed securely and securely.
2. The negative pressure fan is not properly installed. The installation of the negative pressure fan should be in a suspended state. The spring of the foot bolt cannot be crushed.
Solution: Ask the maintenance personnel to adjust the installation status of the negative pressure fan to make it in suspension.
3. The anti-vibration pad or fixing screw of the negative pressure fan base is screwed too tightly, and the vibration-absorbing effect is lost.
Solution: Adjust the screw tightness of the damping pad of the negative pressure fan base to make the base surface smooth.
4. The power supply voltage is too low. When the negative pressure fan starts or runs, abnormal noise and vibration are generated.
Solution: Control the power supply voltage within the rated voltage range. A voltage regulator or power regulator can usually be used to stabilize the voltage.
5. The negative pressure fan blades collide with the fan casing (cover).
Solution: Reasons for adjusting the blade: The fan motor of the negative pressure fan is poorly driven, the screw of the axial fan is loose, the blade is not fixed on the shaft, and the gap between the top of the blade and the hood is too small. Solution: Replace the negative pressure fan motor bearing to tighten the screws on the axial fan base and the shaft. According to the production technical requirements, the distance between the tip of the blade and the casing is generally not more than 1.5% of the length of the blade.
6. The base screw of the negative pressure fan is loose, the impeller is poorly assembled, the rotation speed is too fast, the fixed screws on the shaft are loose, etc.
Solution: Fasten the fan base of the negative pressure fan and the screws on the shaft. Reassemble and adjust the impeller clearance according to technical requirements
The above is the identification method of the performance of the negative pressure fan and the solution of the noise, I hope to be helpful to everyone.
