Choose the right system type for your climate

Hitachi's commercial VRF portfolio offers unrivaled options to meet various usage needs, including single or scalable modular systems, Cooling Only, Heat Pump or Heat Recovery, and special versions for high ambient environments.
VRF Systems_1

Wide choice of VRF indoor units

Hitachi provides an extensive range of indoor units to suit any interior decoration or building function, including ducted, wall mounted, 4 types of cassettes, suspended ceiling, floor mounted, concealed. Optional accessories are also available, including the Twin-Sense panel for 4-way cassettes which automates operation to save energy based on occupant sensing, or the Aqtiv-Ion kit for Ducted units to achieve a healthier indoor environment.

Configure systems up to 4x faster(1) with airCloud Tap

4X faster(1) to configure ODUs and 2X faster(2) to configure IDUs using Hitachi special support mobile app “airCloud Tap”, via NFC technology embedded in selected outdoor units and wired remote controllers.
VRF Systems_3

Easy to operate & automate with airCloud Pro

Control and optimize your HVAC system with ease using airCloud Pro - Hitachi's web/cloud-based Centralized Controller. With a user-friendly smartphone app or web browser interface, remotely monitor and manage your system's energy usage for optimal efficiency. airCloud Pro has won multiple design awards for its innovative and intuitive interface.
VRF Systems_4

Range of individual room and centralized controllers

Hitachi's VRF system provides occupants with award-winning, easy-to-use individual room controllers, while the centralized control system offers complete control of the entire system as an alternative or complement to airCloud Pro IoT control solution.
VRF Systems_5

Lowering the cost of centralized control systems

A common barrier to centralized control of a HVAC systems is the installation and commissioning cost. Hitachi H-LINK lowers this cost by enabling any type of wiring route based on layout rather than on air conditioning system structure. Units can be ‘daisy-chained’ together so that an indoor unit can connect to the nearest indoor unit rather than back to a central control point.
VRF Systems_6

Cut your energy consumption and carbon footprint in half(3)

Compared with VRF technology of just 15 years ago our best-performing air-source VRF systems use half the electricity(3) and equivalent CO2 emissions(4) from electricity production, achieving up to Cooling EER(5) 5.50 and Heating COP(5) 5.21.At the same time, Hitachi's direct capacity control technology SmoothDrive, available on some Hitachi VRF systems, utilizes precise temperature monitoring and control of the scroll compressor frequency to reduce compressor on/off cycles under part-load conditions. SmoothDrive 2.0 is up to 39% more energy efficient(6) under the part-load conditions that regulatory energy efficiency ratings do not account for.
VRF Systems_7

Affordable indoor air quality upgrades

Upgrade the indoor air quality of your space affordably with practical options including the optional Aqtiv-Ion kit for Ducted indoor units, which is 99.9% effective on inhibiting SARS-CoV-2(7) and more than 99% effective on a range of viruses and bacteria(8). Some indoor units also feature standard air-inlet holes to introduce fresh air into your space.

No more cold drafts: GentleCool

When starting up, air conditioners can discharge very cold air to quickly reach the required temperature for the room, but this can result in cold drafts making occupants uncomfortable. With Hitachi GentleCool you can adjust the balance between achieving a lower room temperature quickly and avoiding cold drafts because you can now set your preferred wind (air outlet) temperature separate from the room set temperature.

Warm floors in winter

In room heating scenarios, it’s common to hear users complain of cold feet because heat naturally rises. FeetWarm(9) helps to solve this problem by optimizing airflow in heating mode to ensure that the leg zone is consistently heated. Requires optional cassette panel with Motion Sensor & Radiant Sensor.
