What’s new about VRV IV?

Optimized Installation with New Unit Ranges for low total Life Cycle Cost (LCC)
Larger capacity single modules now range up to 14 tons. Modules can be combined to provide up to 38 tons from three modules on a single piping network, saving installation cost by reducing piping and electrical connections. Plus, system components allow flexibility to handle future building changes while minimizing retrofit requirements.

Energy Efficiency with Variable Refrigerant Temperature (VRT)
VRV IV’s revolutionary Variable Refrigerant Temperature control automatically adapts to the unique requirements of your building and climate, significantly reducing seasonal operational cost compared to VRV III. Customize your operation between Automatic Mode, High Sensible Mode or Basic Mode to suit the application’s needs. >See more about VRT

VRV – Constantly Evolving, Setting the Standard.

VRV IV combines a number of substantial improvements in system capability and function compared to VRV III.

Larger capacity units now utilize new inverter compressors for all configurations. This improves overall efficiency and allows the VRV IV to start with essentially no inrush power. This is ideal for limiting demand expense and for solar installations or facilities that may occasionally run on generator power, where a high amperage starting requirement is difficult to meet.

VRV IV now uses a four-sided coil that presents a greater heat exchange surface. While allowing the same footprint for all unit sizes for ease of design, we have increased efficiency through improved heat transfer on all sizes. This change has also enabled increasing capacity in our standard modules, extending the range up to 38 tons on a single network. Many applications have been simplified, as fewer units can be used to achieve desired performance. Another added benefit to this is a reduction in system refrigerant volume.

Flexibility is everything

  • Large capacity range (6 – 38 ton), up to 64 indoor fan coil units on one system and up to 200% connection ratio
  • Long piping length, up to 3,280’ total, with up to 100’ vertical separation
  • Wide range of indoor units, including additional “mini-split” units
  • Redesigned and optimized for low total Life Cycle Cost (LCC)
  • All inverter compressors in all model sizes
  • New configuration software allows full setup offsite with PC upload
  • 10-year limited warranty* on compressor and parts is standard

* Complete warranty details available from your local dealer or at www.daikincomfort.com. To receive the 10-year compressor and parts limited warranty, online registration must be completed within 60 days of installation. Online registration is not required in California or Quebec.
