Conventional systems air-condition a building as a whole, whereas the VRV system air conditions each room individually. Hence it is ideal for the constantly changing occupancy of a typical building. Even further, precise level control is possible that reacts to the exact conditions in each room. Individual control promotes a far more economical and efficient system.
Space efficiency is enhanced by the compact size of the individual units, the long maximum piping length, and the ability to realize a large scale air conditioning system with a single piping circuit.
