• Introduction16• Systems • Introduction226 Main features6-6 Simple and rapid installation6-6-1 Short installation time• Thanks to small bore refrigerant pipes and REFNET piping options, the VRV II piping system can be installed very easily and quickly.• Installation of the VRV II system can also be implemented floor by floor, so that sections of the building can be put into use very quickly, or enablingthe air conditioning system to be commissioned and operated in stages, rather than on final completion of the project.6-6-2 Dramatic reduction in installation spaceVRV II features a dramatic reduction in installation space - for example, the 16hp outdoor unit is housed in a single casing outdoor unit, providing a 50 %reduction in required installation space.6-6-3 Modular & lightweight• Modular design enables units to be joined together in rows with an outstanding degree of uniformity.• The design of the outdoor units is sufficiently compact to allow them to be taken up to the top of a building in a commercial elevator, overcomingsite transportation problem, particularly when outdoor units need to be installed on each floor.6-6-4 No structural reinforcement necessary• The galbarium steel allows the use of corner block foundations - earlier K and L series VRV systems required full beam foundations.• Thanks to the lightweight and vibration-free construction of the outdoor units, floors do not need to be reinforced, reducing the overall cost of thebuilding.Installation space (16 HP)3.56 m 2 → 1.88 m 2RSXYP16HP VRV K series VRV L series seriesWEIGHT REDUCTION 100 % 99.70 % 66 %K & L series M seriesRSXYP10KLY1 RXYQ16MY1B➧Approx.50 %reductionReductionof 34%
