VRF air conditioning systems

Hitachi offers a wide range of VRF AC systems, including unique solutions like the Centrifugal VRF that enables indoor installation of the outdoor unit, and the world's first slim modular VRF - air365 SideSmart. Hitachi's VRF systems also include industry-standard systems like Top Flow VRF, Side Flow VRF, and Water Source VRF.

The whole range of Hitachi VRF systems provides benefits such as individual comfort assurance, suitability for any type of room with multiple indoor unit options, reduced energy costs, greater flexibility to accommodate building aesthetics and reduce the space needed for HVAC equipment, plus simplified monitoring, maintenance and operation with centralized controls and remote management solutions.

For HVAC professionals, architects, and business decision-makers seeking a reliable partner with an unrivaled VRF portfolio, Hitachi offers unique solutions for building problems, energy-efficient equipment for NetZero or low-carbon footprint building standards, seamless integration with interior designs, and a full range of software tools to simplify and speed up all aspects of the HVAC management lifecycle.

– Wide options of VRF solutions to meet your usage

Hitachi's commercial VRF systems offer unrivaled options to meet various usage needs, including single or scalable modular systems, Cooling Only, Heat Pump or Heat Recovery, Special types for low or high ambient environments, and hot water creation. Hitachi also provides unique form factors such as Indoor Concealed Centrifugal VRF for indoor placement of the outdoor unit and the world's first small-footprint modular VRF system - air365 SideSmart.

– Wide choice of VRF indoor units

Hitachi provides an extensive range of VRF indoor units to suit any interior decoration or building function, including ducted, wall mounted, 4 types of ac cassettes, suspended ceiling, floor-mounted, concealed, and hot water modules. 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.

– VRF Systems up to 4x faster 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 AC remote controllers.

– Easy for building managers and HVAC pros 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.

– 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, allowing for output/input control.

– Lowering the cost of centralized control systems

A common barrier to centralized control of a HVAC systems is the installation and commissioning cost. Hitachi’s centralized controller lower this barrier thanks to H-LINK, which is the very flexible communication system for centralized control, 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 AC systems 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 electricity1 and equivalent CO2 emissions(4) from electricity production, achieving up to Cooling EER(5) 5.50 and Heating COP(6) 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(7) under the part-load conditions that regulatory energy efficiency ratings do not account for.

– VRF systems improve air quality in a cost-effective way

Upgrade the indoor air quality of your space affordably with practical options including the optional ViroSense Z2 filter for 4-way Cassettes with 99.9% SARS-COV-2 inhibition(8) and the optional Aqtiv-Ion kit for Ducted indoor units, which is 99.9% effective on inhibiting SARS-CoV-2(9) and more than 99% effective on a range of viruses and bacteria(10). Some indoor units also feature standard air-inlet holes to introduce fresh air into your space

– VRF air conditioning GentleCool: No more cold drafts

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 VRF cooling system 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 thanks to Hitachi VRF system

In room heating scenarios, it’s common to hear users complain of cold feet because heat naturally rises. FeetWarm(11) 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
