HITACHI
airHome 400 conditioner
Smart. HITACHI airHome 400 self-maintenance technology extends the service life of the device. A household air conditioner that is easy to use and makes everyday life even more comfortable.
Intuitive. The airCloud Home smartphone app detects when you leave or return and raises or lowers the home air temperature accordingly.
Universal. Weekly program, timer function, control of electricity consumption by connecting the HITACHI airHome air conditioner to the smart speaker (compatible with Amazon Echo and Google Home).
Hygienic. The unique "FrostWash" technology helps maintain the high efficiency of the air conditioner: dust and dirt are frozen, thawed and washed away.
Odorless. The anti-mold function of the shut-off unit dries out the internal parts of the unit to prevent mold growth and prevent unpleasant odors.
Safe. By combining 3 different air purification technologies, it destroys 99.9% of viruses, including SARS-CoV-2, and bacteria.
Japanese quality - built to last
Heat and cold shocks, high humidity, heavy rains, power surges, lightning strikes, mechanical impact and more... every air conditioner we sell has been tested under extreme conditions.
The unique SafeGuard electro-mechanical system protects the device's outdoor unit from extreme weather conditions and voltage fluctuations. This protection consists of:
- 3-minute delay circuit to prevent failure due to too frequent restarts of the device after a power failure,
- outdoor unit valve cover that safely diverts water and condensate away from the unit,
- anti-corrosion paint and stainless lamellas,
- a metal fireproof housing that protects the electrical parts inside the outdoor unit.
Vector DC converter technology
Our step-down vector DC converter system is equipped with a chip that controls the speed of the compressor. The rotor with distributed electrical poles allows suppression of electromagnetic noise and improves energy efficiency when operating the device at low power.
Thanks to this technology, when the air conditioner is turned on, it starts cooling at full capacity, then slows down and operates at the lowest capacity that maintains the required room temperature. Models without an inverter work only in the usual "on" and "off" modes. Trying to maintain the right temperature by switching the device on and off uses a lot more electricity, and the temperature fluctuates more.
3 times more efficient self-cleaning system
During the operation of the air conditioner, dust and dirt accumulate in it, so less air passes through the cooling plates, which reduces the cooling or heating efficiency.
HITACHI FrostWash technology helps keep your air conditioner efficient. Dust and dirt are frozen, then thawed and washed away. The HITACHI self-cleaning system with FrostWash technology is 3 times more efficient than systems that do not use this technology*.
The anti-mold function of the shut-off unit dries out the internal parts of the unit to prevent mold growth and prevent unpleasant odors.
*Two identical devices were tested, with and without FrostWash technology. The test chamber simulated approximately 2 years of use in a typical home environment with dust and grease accumulation. Airflow was measured before and after the test chamber. The air flow of the unit without FrostWash technology decreased by 18%, and the unit with FrostWash technology - only 6%.
Tested at Johnson Controls-Hitachi Tochigi Plant, Japan in 2021. November-December
Comfort in the rhythm of your life
Let the smartphone app "airCloud Home" determine your location, predict temperature profiles, for example, when you return home. The temperature will be automatically adjusted until you arrive.
You can also connect to a smart speaker (compatible with Amazon Echo and Google Home) using the airCloud Home app. Use the weekly program and timer functions, see how much energy has been used in the integrated energy consumption calculator.
Combining 4 different air purification technologies, the air conditioner destroys 99.9% of viruses, including SARS-CoV-2 and 99% of bacteria.
