The essential difference between centrifugal fan and ion fan

What is the difference between a centrifugal fan and an ion fan? Due to the difference between a centrifugal fan and an ion fan, many people will mistakenly believe that they are the same fan, but in fact the difference between them is still very big. The following briefly introduces the differences between centrifugal fans and centrifugal fans, so that everyone can distinguish.

　　 Centrifugal fan is a heat exchange device composed of a heat exchanger and a fan. The entire heat exchange process mainly relies on the input mechanical energy, which can increase the gas pressure and discharge the gas. At present, the application range of centrifugal fans is quite wide, including ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air of boilers and industrial furnaces; And cooling and ventilation in air conditioning equipment and household appliances; etc.

　　 The ion fan can be divided into two types: DC electronic fan and AC electronic fan. The former mainly consists of two sets of positive electrodes that simultaneously emit positive and negative ions, so as to achieve the purpose of eliminating static electricity. In the latter, a set of discharge electrodes emit positive and negative ions. The positive and negative ions are emitted first to form a time difference, which is also used to eliminate static electricity. Judging from this, although the working principles of centrifugal fans and ion fans are somewhat similar, they are still different in nature.
