VRV Heat Recovery

Daikin’s current VRV system is the 7th iteration of the first Daikin VRV launched in 1982. Completely re-engineered to realize opportunities for VRV in taller / larger buildings, it utilizes the latest advances in refrigeration and air-conditioning technology. The totally new Daikin Inverter compressor system delivers improved efficiency and performance, while ensuring satisfaction of demands throughout connected zones across the complete operation cycle. With a choice of Heat Recovery 460V/3Ph/60Hz or 208-230V/3Ph/60Hz, the system configurations power up to 28-tons in capacity from a single piping network. The system also allows up to 58 indoor fan coil units, a 200% connection index, ventilation options and integrated controls, with BMS options and piping limitations never before seen with a DX system. With these attributes, VRV naturally positions itself wherever the attributes of traditional chilled water systems are desired.

Options & Capabilities

  • Inverter Heat Recovery units allow for simultaneous cooling and heating from one system
  • Up to 58 indoor units can be operated from a single outdoor unit using a variable-speed compressor system with 48 capacity steps
  • Continuous operation 0F DB (-4F WB) 77F DB (60F WB) in heating mode and -4F DB(with optional wind baffle and field setting) 122F DB in cooling mode
  • Daikin’s optimized scroll compressor designed for R-410A provides a quiet, reliable energy-efficient operation
  • Daikin’s management and oil-equalizing technology assures maximum reliability and flexibility to the VRV system with piping lengths of up to 540 ft., for a total networked length of up to 3,280 ft. of liquid line
