VRML (Virtual Reality Modeling Language) is a language for describing three-dimensional (3-D) image sequences and possible user interactions to go with them.
VRV is a system developed and designed by Daikin Industries and means âvariable refrigerant volumeâ. Daikin protected the term VRV so other manufacturers use the term VRF âvariable refrigerant flowâ.In principle they both work the same and are extremely efficient, reliable, energy saving ways to heat and cool all types of buildings with minimum installation time or disruption.aikin protected the term VRV so other manufacturers use the term VRF âvariable refrigerant flowâ.
