1. Keep main piping

2. Install indoor units with a higher total capacity

Zero ozone depleting

R-410A not only has a zero ozone depletion potential, it is also

proven to be more energy ecient than R-22.

Possibility to Increase Capacity

Cooling loads often increase after to the initial installation of

the air conditioning system. The Replacement VRV(VRVIII-Q)

enables system capacity to be increased without changing

the refrigerant piping (depending on system characteristics).

For example: It is possible to install a 16 HP Replacement VRV on

the refrigerant piping of an R-22 10 HP system.

Technologies of VRV-Q

Reduced Pressure

As R-22 VRV systems used to work on a lower pressure than R-410A

systems / thus the copper refrigerant piping was also designed for

these lower pressures. Therefore the Replacement VRV must operate

at lower pressures than the standard VRV series. However thanks to

the sub cool circuit a high eciency level can be kept even with

the lower pressures.
