V6R Heat Recovery system can perform both cooling and heating operation simultaneously in one system. The energy efficiency can be maximum through divert exhaust heat from indoor units in cooling mode to areas requiring heating. As a result of this, energy efficiency is maximized and electricity costs are reduced. The part load efficiencies are high as well (EER up to 7.8 in 8 HP category). The latest and greatest system is here with many industry First features and functions.
