Heat load calculation
Heat load calculation
(OP)
We have a 600V 3 phase 500 KVA motor generator set. I need to do a calc to determine how much this unit loads the A/C system for this building. I have all the electrical data for the motor and sychronous generator. Where can I find guidance on how to do this calc?






RE: Heat load calculation
Out = Motor Generator Output Power
In = Motor Generator Input Power
Losses = Power Dissipation to be removed by ac
If you have output and input power:
Losses = In - Out
If you have In and Eff
Eff = Out/In = (In-Losses)/In
In * Eff = In - Losses
Losses = In*(1 - Eff)
If you have Out and Eff
Eff = Out/In = Out/(Out+Losses)
Eff*Out+Eff*Losses = Out
Losses = Out * (1/Eff-1)
