[Equest-users] Fan Diversity Factor Adjustment

[Larry Yang]

If I remember it right. the system you mentioned is a heat pump system. With this type of system, the ventilation air is usually provided by a central AHU where the central fan power will be reported. If this is the case of your whole system then your heat pump unit fan power should be modeled at each zone component instead. The fan diversity factor is correct.

Hope this helps,

Regards,

Larry

Subject: [Equest-users] Fan Diversity Factor Adjustment

 

Dear Users,

Could anyone kindly advise that under Detailed Mode, where I can adjust the "Diversity Factor" of fans? For reason I don't know, the default value in one of the HVAC systems in my model is 0, which lead to 0 kW of fan power under huge amount of ventilation capacity, as SV-A report shows. However, I cannot find that under Detailed Mode, where I can input this factor. Any answer will be greatly appreciated. 

Cheers,
Rick, LEED AP
