[EnergyPlus_Support] Re: Zone Radiant HVAC Mass Flow Rate equal to 0 but system controlling the room temperature. How???
Hi Luke,
Firstly again, a thousand thanks for your help, it has been crucial for seeing the problem from new different
points of view and I finally solved it.
I think that one of the best ways to thank this kind of contribution is giving my feedback in order to get a better
understanding of EnergyPlus operation.
1. Effectively, it seems that "Zone List Sensible Cooling Energy" variable is not working with radiant
components, although I don't know if the scope of this variable is only reduced for airside. I had already
checked the "Zone HVAC Cooling Rate" variable but it was zero while I had the problem. I think that every
output variable related with the "ZoneHVAC:LowTemperatureRadiant:ConstantFlow" was set to zero or
default value due to the fact that the execution of this component in EnergyPlus was like locked, I mean,
like if EnergyPlus had jumped until the end of his zonehvac programming lines and had left everything in
zero. I explain at the end what I think was the problem.
2. I agree with you in that EnergyPlus is "something particular", but in this case it wasn't necessary to fill
the "pump efficiency" field given that it finally worked.
3. Regarding the point 1., through your mention of that no every variables are for every systems, I realized
that the "Zone Predicted Sensible Load to Cooling Setpoint Heat Transfer Rate (W)", which I was using in
order to see if there was a cooling load in the building, needs in an indispensable way the addiction to the
model the "ZoneControl:Thermostat" object since the "s
