Historicay, demand for high heating capacities and efficiencies in cod and very cod regions has forced engineers to use a combination of backup heat and/ or conditioned mechanica rooms when reying on heat pump for heating soutions. Daikin VRV AURORA air-cooed systems introduce a new benchmark for the VRF industry by integrating advanced technoogies to deiver comfort, precise contro, reiabe and energy efficient heating soutions for cod cimate appications. VRV AURORA systems can simpify design and optimize cost by deivering heating capacities down to -22 F (-30 C). The increased heating capacities at ower ambient temperature, compared to VRV IV systems, provide an aternative soution to hep minimize the need for backup heat or conditioned mechanica rooms to deiver reiabe heating operations in cod cimates. 2
