According to the diversification of its installation environment, the installation plan of the industrial air cooler is customized one-to-one according to the site environment. During the customization process, the layout of personnel, noise requirements, installation environment, air supply mode and other aspects will be considered. Comprehensive factors, that is, it is possible to use a centrifugal air cooler with higher wind pressure and lower noise, or it may be more suitable for an axial flow water cooler with low wind pressure and large flow. What is the difference

First The difference in principle 

For centrifugal air cooler: the air flow axially flows into the rotating blade channel, is thrown to the outer edge of the impeller under the action of centrifugal force, and is discharged from the air outlet.  

For axial-flow air cooler: the air enters the rotating blade channel axially, is pressurized, and then is discharged axially from the other side.

Second, the machine structure is different

For centrifugal air cooler composed of impellers, casings, current collectors, motors and transmission parts (main shaft, pulleys, bearings, V-belts and other accessories). The fan is connected through the shaft, which is more applicable to the requirements of air volume and pressure, and the cabinet can be silenced, which has obvious advantages in terms of noise.

For axial-flow air cooler is also composed of impeller, casing, current collector, and motor. The impeller is composed of blades and hubs. The diameter of the blade is limited to the diameter of the casing, and the motor can only be installed in the fan.

Three, air volume and air pressure are different

The centrifugal machine has a strong pressure coefficient, but a relatively low flow coefficient. According to the wind pressure of the machine, it is divided into three types: high pressure, medium pressure, and low pressure.

The axial flow machine has the characteristics of low pressure and large flow. According to the wind pressure, it is divided into high pressure and low pressure. The general-purpose axial flow environmental protection air conditioner host is generally a low-pressure machine, and the general high-pressure machine is a Large air volume machines need to be customized according to the parameters.
