6 Simple and rapid installation
6-9 Downsizing refrigerant piping
• Reduced piping diameters
Use of high efficiency R-410A enables the VRVII to operate on a smaller refrigerant charge to be used, leading to a reduction in liquid and gas pipe diameters.
• Reduced piping costs thanks to modular design
Smaller diameter liquid and gas piping contributes to a reduction in installation space and installation costs.
