Re: [EnergyPlus_Support] Sizing: system object -





Thank you for answering, but if we have a situation with a significant internal latent load, lets say a theater wonâ??t this mean that that the design air flow calculated for the system will be insufficient to achieve comfort conditions for the occupants?

 

Thanks once again

Field: Type of Load to Size On

The user specified type of load on which to size the central system. The choices are Sensible, Latent, Total and VentilationRequirem ent. Only Sensible and VentilationRequirem ent are operational. Sensible means that the central system supply air flow rate will be determined by combining the zone design air flow rates, which have been calculated to meet the zone sensible loads from the design days. VentilationRequirem ent means that the central system supply air flow rate will be determined by the system ventilation requirement.

Hello to everyone

In the sizing: system object, according to the Input/Output reference guide, on the type of load to size on field there are two options, sensible and latent, being the sensible load the only one operational. But while working with the IDF editor I found that there is another option: Ventilation Requirement. 
Does anyone know why is the type of load to size on only the sensible and what's with the field Ventilation Requirement, what does it do?

Thanks and have a good day
