Re: [EnergyPlus_Support] Zone controls and thermostats
Zone sensible load predicted gives you the thermostat load. If it is
zero, there is no load. The zone temperature is below the cooling set
point and/or above the heating set point. This is the thremostat dead
band region. The zone sensible load to heating setpoint predicted is
negative because the zone temperature is above the heating set point.
The zone sensible load to cooling setpoint predicted is positive because
the zone temperature is below the cooling set point.
Change your thermostat set points and you will see that when there is a
cooling load, the zone sensible load to cooling setpoint predicted will
go negative when the zone temperature is above the cooling setpoint. And
when there is a heating load, the zone sensible load to heating setpoint
will go positive when the zone temperature is below the heating
setpoint. The zone sensible load predicted should also show these same
results.
If your thermostat setpoints are correct, you will have to change the
zone loads. More outside air will likely cause a load in the zone for
both winter and summer. Or adding equipment/lighting loads will cause a
cooling load in summer (and possibly winter).
