Modules can be combined to provide up to 34 tons from three modules on a single piping network, saving installation cost by reducing piping and electrical connections. Reduced install cost and increased flexibility as compared to VRV III with larger capacity single modules up to 14 tons and system capacity up to 34 tons Daikin’s new VRV IV Heat Pump offers a simplified range of condenser unit combinations with the expanded capacity to fit more projects when compared to VRV III. Ranging from 6 to 34 tons in a single system, all versions of the VRV IV feature inverter controlled compressors and the new Variable Refrigerant Temperature control cycle for improved seasonal efficiency when compared to VRV III. Currently available in heat pump and heat recovery configurations, VRV IV provides a solution for multi-family residential to large commercial applications desiring heating or cooling. The VRV IV is the first variable refrigerant flow (VRF) system to be be assembled in North America.
