[EnergyPlus_Support] simultaneous heating and cooling

["eric_zhou1223" <eric_zhou1223@xxxxxxxxx>]

Hi all,

In my model, there are always the simultaneous heating and cooling 
in central units. It seems there is a problem in Setpoint:manager 
but I just can not dig it out. Also, there are other two problems:

1. The overall winter cooling load (CoolingCoils:Energy transfer)is 
unreasonably large and the tendency from Jan to March also doesn't 
make sense. In January the cooling load get its maximum in winter 
season ;

2. Electricity spent on the space heat (see HTML) in EnergyPlus is 
about 4 times as much as that for the space cool. It seems too high 
for the corresponding weather;

3. The temperatures in zones is not well controlled

Please see the uploaded file "simul_Heat_Cool.idf" and related 
weather file in the submittal files area.

The problems keep annoying me for a long time and I tried many ways 
to fix them but failed
Can anybody kindly give me a quick hand? It is urgent. Any help 
would be much appreciated. 

Eric
