Fan selection, air volume calculation
Thread Content
May I ask, in fan selection, how is the required air volume for the system calculated?
Without any background information, it’s impossible to answer this
First of all, your wealth isn’t necessary :) The fans should be configured according to the requirements of the system, right?:)
Different processes require different fan selections. For conventional processes, the air volume required is determined by multiplying the process’s air volume demand by a coefficient. For some large-scale fans, such as those used for boiler exhaust, it is necessary to determine the air volume at the BMCR and TB points
Specifically, what is this fan used for? The operating conditions are very important
It depends on your purpose; the calculation method varies depending on the use case
