Total comfort solution for heating, cooling, ventilation and controls.

Daikin’s VRV IV systems integrate advanced technology to provide comfort control to help maximize energy efficiency and reliability. 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 assembled in North America.

  • VRV with Variable Refrigerant Temperature (VRT) technology
  • Energy efficient simultanoues cooling and heating from a single system
  • Capacity range from 6 to 38 tons
  • 208-230V / 3ph / 60Hz
  • 460V / 3ph / 60Hz

N/A Features

  • Variable Refrigerant Temperature (VRT) control allows the VRV IV to deliver up to 28 % of improvement in seasonal cooling efficiency compared to previous Daikin VRV heat recovery systems
  • Improved efficiency with IEER values now up to 29.3
  • Can provide heating down to -13 ºF WB as standard
  • Larger capacity single modules ranging up to 14 tons and systems up to 38 tons allow for a more flexible system design, when compared to VRV III
  • New configurator software designed to simplify the commissioning and maintenance of the system
  • Standard Limited Warranty: 10-year warranty on compressor and all parts
  • Larger capacity single modules allow for opportunity to reduce electrical connections, piping connections and outdoor unit mounting fixtures
  • All inverter compressors to increase the efficiency and avoid starting current inrush
  • Assembled in the US to increase flexibility and reduce lead times
  • Factory standard coil guards

N/A Benefits

  • Can operate up to 64 indoor units on a single piping network
  • Inverter control board cooled by refrigerant to avoid influence from ambient temperatures
  • Integrated inverter technology deliver maximum efficiency during part load conditions and provide precise individual zone control
  • Heat exchanger coil wraps around on all 4 sides of the unit to increase the surface area/efficiency
  • Modular and lightweight - enables flexibility in system layout and installation
  • Ultra gold fin coating with a salt spray test rating of 1000 hours provides superior corrosion resistance for applications near seacoasts and other corrosive environments
  • Design flexibility with long piping lengths up to 3,280 ft. total and 100 ft. vertical separation between indoor units
  • Designed with reduced MOP to optimize installation cost
  • Digital display on the unit for improved and faster configuration, commissioning, and troubleshooting
