Hitachi VRF Air Conditioning offers optimal solutions for architects, contractors, installers, and investors.

Modern building architecture poses stringent challenges to HVAC systems, and an ideal air conditioning solution goes beyond conventional cooling or heating capabilities. It must optimize performance, offer superior flexibility in space, and minimize operating costs. Therefore, Hitachi VRF air conditioning, exemplified by the new generation Hitachi air365 Max series, provides a perfectly balanced living environment. Combining cost savings and flexibility, Hitachi VRF air conditioning offers a comprehensive solution for architects, contractors, installers, and investors.

Hitachi air VRF solves the aesthetic, space-saving, green design, and interior space challenges for architects

For architects, the challenge of balancing technical functionality with the original aesthetics of the building is always present. One of the major difficulties is that air conditioning systems often inadvertently disrupt interior and exterior design lines if not flexible enough. Understanding this difficulty, Hitachi's VRF air conditioning system was created to solve this problem flexibly with its superior variety of indoor units. In particular, the system offers up to 18 diverse indoor unit designs, optimized for various types of spaces.

The ducted concealed ceiling units provide different static pressure levels, significantly saving ceiling space. Furthermore, the cassette, ceiling-mounted, and wall-mounted units are designed with sophistication to seamlessly integrate into any interior style, from classic to minimalist.

The compact outdoor unit design, measuring only 1.2 square meters, offers a capacity of up to 30HP, saving space for outdoor installation. It can be easily concealed on balconies or rooftops without affecting the building's aesthetics and significantly reducing weight. The new generation outdoor unit structure boasts a smaller and lighter size compared to traditional systems. This allows architects to have more valuable space on rooftops or technical balconies for architectural greenery or solar panel systems. Furthermore, the high external static pressure setting allows the outdoor unit to be installed inside ventilated technical rooms instead of being required to be placed outdoors, preserving the aesthetic integrity of the building's exterior facade.

Maximum flexibility in piping configuration is offered by Hitachi air VRF, extending the design limits with a total system piping length of up to 1,000m. The maximum practical pipe length from the outdoor unit to the furthest indoor unit is up to 200m, and the maximum height difference reaches 110m. These specifications allow for the free deployment of air conditioning solutions in any complex building design, from sprawling villas to high-rise buildings. High efficiency (EER up to 5.40) supports buildings in achieving LEED, EDGE, and LOTUS certifications due to reduced electricity consumption.

Hitachi Air VRF offers optimal solutions for contractors

For contractors, high compatibility, versatility, and the ability to operate under all weather conditions are crucial factors in winning bids and project timelines. Hitachi VRF air conditioning provides diverse options to suit different climates and functional needs:

Cooling Only Type: A specialized solution optimizing investment costs for areas with year-round hot tropical climates.

Heat Pump Type: A system that flexibly switches between heating and cooling according to the season, operating intelligently based on priority algorithms.

Heat Recovery Type: A cutting-edge technology that allows a system to run both cooling and heating simultaneously in different rooms. The intelligent automatic changeover system can utilize waste energy from areas requiring continuous cooling to convert it into heat energy for heating surrounding office areas during colder seasons, thoroughly optimizing the overall energy efficiency of the building.

The Hitachi air365 Max VRF system is designed for stable and durable operation in various harsh environments, maintaining consistent cooling performance even when outdoor temperatures reach 52°C (or automatically activating the intelligent Thermo-OFF protection feature). The robust casing structure allows the unit to withstand direct wind speeds up to 60 m/s.

If the project is located in a harsh weather environment, contractors should consider applying anti-corrosion treatment to the outdoor air365 Max units. This involves factory treatment and arrangement according to JRA9002 standards, with multiple coatings on each component of the equipment. With this therapy, lifespan in a salty sea air environment can be doubled. It is also effective against geckos/toads.

Integrating Hitachi VRF into existing air handling units (AHUs) through seamless connection with high-quality ventilation solutions and the Dx-kit connector makes it easy for contractors to integrate and comprehensively address indoor air quality (IAQ), providing fresh, clean air to entire spaces from office buildings and hotels to schools and hospitals without the need for separate installation of complex third-party air handling systems.

Our technical team optimizes the installation process with smart solutions from the new generation Hitachi air VRF

On-site installers are always under pressure regarding construction time, the complexity of signal wiring, and the risk of system errors during setup. The Hitachi VRF system is designed to work harmoniously with both indoor and outdoor spaces, is lighter and smaller, and is easier and cheaper to transport. The new outdoor unit enclosure is designed to optimize loading and unloading by integrating dedicated central access points for forklifts or hand-lifters, even without pallets. At the same time, precisely positioned external access points are available for crane cables when lifting equipment to the building's rooftop. The compact size also optimizes loading space in containers, increasing load capacity by up to 14% for L-shaped cabinet units in 40ft containers, significantly reducing long-distance shipping costs.

Hitachi's H-LINK network control communication system allows technicians to connect signal wires in a serial configuration, connecting indoor units to indoor units in series, and from the nearest indoor unit to the outdoor unit. This improvement eliminates the traditional complex star wiring structure, simplifying the electrical control installation of buildings, saving a significant amount of cabling materials, and shortening on-site signal wiring installation time by more than 50%.

In addition, Hitachi air conditioners integrate Near Field Communication (NFC) technology directly on the outdoor unit's circuit board and next-generation room controllers. Installation no longer requires opening the entire electrical box or manually flipping each DIP switch. Simply launch the airCloud Tap application on your smartphone, tap the device, and you can quickly and accurately read all data and configure operating parameters for one unit across multiple other units.
