As we all kown,PVVT System can be used to model VRV/VRF system in eQUEST software,but what I am confused is Why pvvt system can be used.Pvvt system is Packaged Variable-volume Variable Temperature system.Load adjustment is implemented by varing spupply air flow and supply temperature.But it is implemented by varing refrigerant flow in each coil.There is a significant difference bettween the load adjustment way of both systems.And we always can not get resonable result using this way,the heating energy cosumption is always very too small.

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

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

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 it in VRv system，load adjustment is implemented by varying refrigerant flow in each coil. There is a significant difference between the load adjustment method of both systems. vrv and pvvt system. And we l always can not get reasonable result using this way, the heating energy consumption is always way too small.

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

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.
