[EnergyPlus_Support] Load calculation differences



Deal all

I simulated two cases for the comparation of load calcuation results
First case just divide the floor into three zones.
Second case divide two zones into eight small zones further.
The system is using purchased air. They have same setpoint, same 
schedules for miscellaneous purpose. And the simulations carry out 
successfully.
But the purchased heating results show a large difference up to 80%, 
while the purchaed cooling results are limited in 5%.
Why do the simulation results have such a large difference?
Thank you in advance

Charlie
