Wall Mounted Inverter Heat Pump AC

Home AC that’s easy to use – packed with smart automation technology to make your life easier, reduce energy consumption, and enhance sleep quality. Integrated self-maintenance technology helps to improves the long-term performance of the unit. airHome is the AC for people who don’t want to think about AC.

– Adjusts temperature as you arrive home or leave the house

Use the airCloud Go smartphone app to set up location awareness and temperature profiles, for example, detecting when you are on your way home and automatically adjusting the temperature ready for your arrival.

With the airCloud Go app you can also connect to your smart speaker (compatible with Amazon Echo and Google Home), use weekly schedule and timer functions and see how much power has been consumed with the integrated Energy Cost Estimator.

– Helps to reduce energy bills

Smart Eco detects when nobody has been in the room for 20mins or more, and gradually increases the set temperature to reduce energy consumption. If the additional Auto-off feature is set, the unit will switch off after a preset time and not resume again until manually started.

– Contributes to sleep quality

Set a cooler temperature to help you fall asleep, knowing that SleepSense will automatically increase the temperature once it detects you are sleeping, preventing the room from getting too cold and reducing energy consumption.

– Distributes air across your room

Distributes air effectively across any room in your house, reaching up to 24metres away^[1] and automatically distributing air across a 105º by 60º 3-dimensional arc.

– 3X better at maintaining the performance of your AC

Over time dust and dirt can build up in your AC reducing the amount of air that can flow through it and making it less powerful over time.

Hitachi FrostWash technology helps to maintain the performance of your AC for years to come by freezing dust and dirt, melting it and washing it away. Our tests show that systems with FrostWash are 3X better at maintaining air flow performance than those without this technology^[2].

– Stop the causes of AC odors

Whenever the unit is switched off, the mold guard function automatically blows air through internal components to prevent the build-up of mold – the primary cause of those nasty odors.

– Japanese quality, built to last

Heat and freezing shock, extreme humidity, torrential rain, voltage surges, lightning strikes, impacts and more… every air conditioner we sell has been tested to the extreme. In addition, our unique SafeGuard System combines electrical and mechanical systems to protect the outdoor unit from extreme weather and voltage fluctuation. These protections include a 3-minute delay circuit to prevent damaged caused by multiple fast re-starts in the event of power cuts, an ODU valve cover to channel water and condensation safely away from the outdoor unit, anti-rust paint and heat fins, and a metal fireproof electrical enclosure to protect electronics inside the outdoor unit.

– Helps to purify your indoor air

Combining 4 different air purification technologies for enhanced effectiveness against pollutants including viruses, allergens, bacteria and even odors. The pre-filter, air purification filter, heat exchange cleaner and ionizer all work together with up to 99.9% effectiveness on viruses including SARS-CoV-2^[3], up to 99.0% effectiveness on bacteria^[4], up to 86.0% effectiveness on odors^[5] and up to 97.1% effectiveness on allergens^[6].

– Vector DC Inverter technology

Our Cascade Vector DC Inverter System is equipped with a microchip to control the speed of the compressor. A split rotor with displaced electrical poles enables electromagnetic noise suppression and optimizes low-speed energy-efficiency.

With inverter technology, an air conditioner cools with maximum capacity at start-up, then automatically slows down and operates at a minimal capacity to maintain room temperature at a comfortable level. Non-inverter models can only operate with simple on-off controls. Trying to maintain the desired temperature by repeatedly switching power on and off consumes much more electricity and results in bigger temperature fluctuations.

Notes

[1] Airflow distance will vary according to fan speed setting, environmental factors and model capacity. Claim refers to models with 18kBTU/5.3kW/1.5T capacity and fan speed of 1200rpm creating an air velocity of 0.15m/s or more according to anemometer tests.
[2] Two identical units were tested for comparison; with and without FrostWash. Test chamber simulated approx. 2 years of dust and oil build up which may be experienced in a typical home environment. Airflow performance was tested before and after being in the chamber. Unit without FrostWash experienced an 18% drop in airflow performance. Unit with FrostWash experienced only 6% performance drop. Tested at Johnson Controls-Hitachi Tochigi factory, Japan Nov/Dec 2021.
[3] An air conditioner is not a replacement for any COVID control measure recommended by governments or medical professionals. Claim refers to the effect of AQtiv-Ion (optional on some models) which showed 99.9% reduction in COVID virus particles under lab conditions tested at Nara Medical University, Japan and 99.9% reduction in Hong Kong Influenza A (H3N2), tested at Biomedical Science Association. ViroSense Z1 filter shows 99.9% of effectiveness against SARS-CoV-2 NIID isolated variant: JPN/TY/WK-521 and 99.0% effectiveness against Influenza A Virus (H3N2) tested at Japan Textile Product Quality and Technology Center using ISO18184:2019 method. FrostWash technology also showed 99.0% reduction of virus particles on the heat exchanger tested at Kitasato Research Center of Environmental Science
[4] Claim refers to the effect of ViroSense Z1-filter (optional on some models) which showed 99.0% reduction of Staphylococcus aureus NBRC12732 and Escherichia coli NBRC3301 bacteria particles under lab conditions tested at Nissenken Quality Evaluation Center Japan, and also FrostWash technology which showed 99.0% reduction of bacteria on the heat exchanger tested at Kitasato Research Center of Environmental Science Japan, and also AQtiv-Ion (optional on some models) which showed 99.0% reduction in E.Coli particles and Staphylococcus Aureus tested at Boken Quality Evaluation Institute Japan following JIS Z 2801 standard
[5] Claim refers to the 86% reduction effect of AQtiv-Ion (optional on some models) on formaldehyde, tested at Kinki Bunseki Center, Ltd. Japan.
[6] Claim refers to the effect of AQtiv-Ion (optional on some models) on Cedar allergens which shows 97.1% reduction, tested at Institute of Tokyo Environmental Allergy.

– Other Benefits

Silent Mode

Specially curved fan blades reduce the buffeting noise of them cutting through the air at slower speeds.

0.5°C temperature control

Set temperature in increments of 0.5°C.

Multiple Timers

6x On/Off time and temperature settings for each day of the week (using airCloud Go). Set a specific time interval for power off, up to 12 hours.

Save your favorite settings

Quickly activate your most-used combination of mode, temperature and fan speed with a dedicated button on the remote control.
