Easy and flexible design

5-1 Total room layout flexibility - VRVII & VRV-WII
• VRVII systems are easily adaptable to changes in room layout : extra indoor units can be added to a VRV outdoor unit up to a capacity level of 130%.
• Also, since VRVII heat recovery systems offer simultaneous cooling and heating, existing indoor and outdoor units can continue to provide year round
air conditioning from their existing locations, even if office layouts are altered or extended.

5-2 Complete flexibility - VRVII & VRV-WII
• The VRVII/VRV-WII system enables different floors or even rooms to be rented to different customers, because each room has independent control of its air
conditioning.
• Thanks to inverter technology, as many as 40 indoor units (32 indoor units for VRV-WII) with different types and capacities can be installed in one
system. This system automatically and effectively controls each unit to provide individual rooms of different sizes with a comfortable working or
living environment.

Year round cooling and/or heating

VRVII & VRV-WII
• Designed to provide simultaneous year round cooling and/or heating, VRVII heat reovery systems are modular in concept and are therefore, ideal
for use in rooms or zones that generate varying thermal loads according to building orientation or local cold or hot spots.
VRVII & VRV-WII
• It is possible for the same meeting room to give rise to differing thermal loads depending on the time of day, number of occupants present, location
and usage pattern of lighting and electronic office equipment.
VRVII & VRV-WII
• Until the advent of the VRV, a complex 4-pipe fan coil was needed to meet this requirement. The VRV however, is easier to design and install an in
its heat recovery format, can conserve energy in two or more rooms at the same time.
VRV-WII
• The colder it is outside, the warmer it needs to be indoors, which means that the capacity of the air-cooled outdoor unit drops. Water-cooled air
conditioners are not subject to this problem. The boiler ensures that sufficient enough additional heat is always available indoors.
