Re: [TRNSYS-users] Air Mass Flow Rate Dependent Fan

Most fan models take a rated flow rate as a parameter and a control signal as an input. These two values are multiplied together to set the fan outlet flow rate. In a way, this is the same as giving the fan an inlet variable mass flow rate provided that you have chosen a variable speed fan model where the control signal can vary between 0 and 1. There is a fan model in the TESS Hydronics library (Type744) where you truly do set the inlet mass flow rate directly as an input to the model.

kind regards,

Hello, can anyone tell me about a component used as a fan whose input is variable mass flow rate of air and whose power consumption variate with mass flow rate... Please guide me, i am stuck.......
