Dear all
If any one has detailed information between the difference between VRV and VRF,please send that to me .Please send that to my email id [EMAIL= E mail address removed by the moderator. [/EMAIL].

They are essentially the same thing, EXCEPT the term VRV is copyrighted by daikin. for example a system by daikin may be called a VRV, but a similar system made by fujitsu is a VRF.
VRV = Variable Refrigerant Volume, VRF = Variable Refrigerant Flow.
.
It's as Acidslasher remarked.
They are two interchangeable terms for the same machine. It means the same.
Following Daikin's registration of 'VRV' as a 'trade name', VRF has become the accepted generic term for these machines.
.
VRF as used by Mitsi and others is the more acurate term. :D
VRF - Variable Refrigerant Flow is essentialy what goes on inside the system. :p
VRV - Variable Refrigerant Volume does not really happen so therefore Daikin can keep their Guarded terminology! :rolleyes:
yeah the actual volume of refrigerant doesnt change, so i dont know why its called variable. Flow is much more accurate.
Refrigerants, when they exist in gaseous state, they are compressible and so their volume can be varied. ;)Quote:

Ø Higher COP
Ø Continuous heating during defrost
Ø No capacity loss during indoor mode change
