The choice of tall space air conditioning heating units
With the rapid development of my countrys modern construction project and social industry, many tall space buildings have been unplugged. In the heating of tall spaces such as some gymnasiums, conventions and exhibition centers, logistics warehouses, industrial workshop factories, and large supermarket buildings, special tall tall tall tall are used Space air conditioning heating equipment has become the main trend, and when choosing a high space air -conditioning heating equipment, it usually involves the choice of centrifugal fan and axis flow fan. What is the difference between centrifugal fan and axis flow? What are the advantages and disadvantages? Lets take a brief understanding.
1. The difference between axial flow fan and centrifugal fan
The characteristic of the axis fans is that the fluid flows along the axial direction of the fan blades, such as an electric fan and an exhaust fan in the family.The centrifugal type is to use the centrifugal force to throw the fluid out of the circular direction with the centrifugal force from the axial direction of the fan, such as a blossom.
2. The advantages and disadvantages of axis flow fan and centrifugal fan
The axial flow ventilator is generally large and the wind pressure is small, and the diameter of the blasts of the fan is limited to the diameter of the shell.
The centrifugal fan can be leaned forward or the blade backward leaning. The requirements for air volume pressure can be more adaptable, and it can be processed in the cabinet. It has obvious advantages in the noise index.At the same time, centrifugal fans are more advantageous than the combination of large air volume and wind pressure (mainly referring to the efficiency and noise indicators).
3. Applicable occasions of bearing fans and centrifugal fans
The axis flow fan is generally used in unusual ventilation systems. For example, the fire fans in the fire exhaust system use a bearing fans.Corporations are generally used in commonly used ventilation systems, such as combined air -conditioning units, air processing machines, and fan disk pipes.
4. The necessity of using a centrifugal fan with a high space heating unit
Due to the effect of hot buoyant, thermal air rises, the heating of tall space buildings will cause great energy waste.The high space air conditioning heating unit is to solve this problem. It is mainly used for the heating equipment for heating in high space. Therefore, for the heating of some high spaces, it is recommended to use a large air volume and heavy wind pressure.The hot air in the upper part of the workshop is blowing to the personnel activity area.If a small -power axis flowers are used, the expected temperature requirements cannot be met.
