As we all know, Packaged Variable-volume Variable-Temperature (PVVT) systems can be used to model VRV/VRF system in eQUEST software, but what I am confused is why a PVVT system can be used.

Load adjustment in pvvt system is implemented by varying supply air flow and supply temperature. But in VRv system，load adjustment is implemented by varying refrigerant flow in each coil. There is a significant difference between the vrv and pvvt system. And l always can not get reasonable result using this way, the heating energy consumption is always too small.

Can someone explain why a PVVT is usually chosen to model VRV/VRF?

There is a significant difference between the vrv and pvvt system. load adjustment method of both systems. And l we always can not get reasonable result using this way, the heating energy consumption is always way too small.

Load used.Pvvt system is Packaged Variable-volume Variable Temperature system.Load adjustment is implemented by varying supply varing spupply air flow and supply temperature. But temperature.But it is implemented by varying varing refrigerant flow in each coil. There coil.There is a significant difference between bettween the load adjustment method way of both systems. And systems.And we always can not get reasonable resonable result using this way, the way,the heating energy consumption cosumption is always way very too small.
