There is a fan design in the combined air conditioning purification equipment, and the performance of the equipment is also closely related to this part, so the selection of the fan is very critical. The following will teach you how to choose a suitable fan for the combined air conditioning purification equipment to ensure the best operating state of the device.
When choosing a fan, the main thing is to look at its quality and several important parameters, such as the air volume and air pressure margin should not be too large. Moreover, due to the improvement of construction quality, the intimacy of the air duct has also been greatly improved, so the lower limit of the air leakage coefficient of the air duct system can be taken.
Because under normal circumstances, the air volume and pressure head of the fan cannot be satisfied at the same time, so after careful calculation of the system resistance and consideration of the margin, priority should be given to meet the needs of the pressure head, while taking into account the requirements of air volume. In this state, even if the air volume is smaller in time, it will not have a great impact, because the surplus has been taken into account in the calculation.
However, the fan pressure head cannot be selected arbitrarily. If it is too high, it will easily cause adverse effects, including increased operating noise, increased air volume, etc., which is also a waste of energy.
