[EnergyPlus_Support] Re: Zone Radiant HVAC Mass Flow Rate equal to 0 but system controlling the room temperature. How???
Hi Luke,
Firstly, thank you very much for your reply, it is always interesting different points of view for learning.
Regarding the blanks, I only left blanks in the ZoneHVAC:LowTemperatureRadiant:ConstantFlow
object the following fields:
- "Pump flow rate schedule name".
- "Motor efficiency".
- The 6 fields for heating since this model is only for cooling season.
So, any other field is filled with mass flow rate, pump head, pump power, etc...
The thing is that the system works for all cooling season months, remove the load, keep the setpoint
and has an energy consumption (the last one only in the hottest months). It looks like the energy
consumption wasn't showed in the csv file if it is very low, like an approximation to zero (this one in
the coldest months during the cooling season), but for me it doesn't make sense... whatever energy
consumption of the system should be showed in csv file whatever it was instead of zero.
An important note would be that I have taken the output for "Zone List Sensible Cooling Energy" and it
is 0. How is it possible when I have seen that there is a regulation in the rooms? and even more, when
the same building was simulated with a fan coil terminal unit and there was an energy consumption for
the same month.
It is very very strange, there is a control, there is a load, but no an energy consumption even if it was very low.
Zone List Sensible Cooling Energy with Fan Coil (April) = 173,03 kWh
Zone Lis
