Classification of Hitachi wall-mounted split air conditioners

Hitachi wall-mounted split air conditioners boast high energy efficiency ratings (CSPF) and incorporate FrostWash and SafeGuard technologies. At U.P Tech, we offer a diverse range of Hitachi RAC systems wall-mounted air conditioner across various models and price segments.

The airHome 600 series is our top-of-the-line product with superior energy savings (CSPF up to 6.48 - 5.96). With capacities of 18,000 BTU (RAK-PH18ASV) and 24,000 BTU (RAK-PH24ASV), it features built-in Wi-Fi (airCloud Go), a ViroSense Z1 filter, and a Smart Eco mode that automatically adjusts temperature to save energy using intelligent motion sensors. It's ideal for large living rooms or spaces requiring the highest level of luxury and comfort.

The airHome 500 series is a 5-star standard inverter series, focusing on absolute quietness. Capacity ranges from 9,200 BTU (RAK-PC10ASV), 12,300 BTU (RAK-PC13ASV) to 23,000 BTU (RAK-PC24ASV). Additionally, the Refresh mode reduces humidity for faster cooling while maintaining quiet operation, making it the perfect choice for master bedrooms or offices requiring maximum quietness.

The airHome 400 series features built-in Wi-Fi connectivity, allowing users to control it via smartphone immediately upon purchase without needing additional accessories. It offers common capacities ranging from 9,000 BTU to 18,000 BTU.

The airHome 300 series utilizes DC Vector Inverter technology, ensuring stable operation even with voltage fluctuations. Capacity ranges are concentrated at 9,000, 12,000, and 18,000 BTU. This is a popular choice for modern serviced apartments and townhouses.

The airHome 100 series (Fixed Speed ​​Compressor - standard model) is designed for users prioritizing extremely fast cooling and low initial investment costs. While not using an Inverter, the airHome 100 series is still equipped with comprehensive protection systems and corrosion-resistant heat exchangers. With durability comparable to high-end models, it's suitable for small spaces or areas with low usage frequency.

The airHome dual-mode cooling and heating series (HJV/HMV series) is the optimal solution for harsh climates, especially the winters in Northern Vietnam or highland regions with cold climates, with two models: RAK/RAC-HJV or RAK/RAC-HMV. It utilizes an intelligent reversing valve system, flexibly switching between cooling and heating. Hitachi wall-mounted split air conditioners offer high heating efficiency, keeping the air in the room from drying out and providing a natural warmth instead of conventional heating with heating elements.

Hitachi air conditioners are particularly known for their higher current cooling capacity compared to other brands on the market. For example, models with a capacity of 10,000 BTU are 1 HP units, while 13,000 BTU are 1.5 HP units. All Hitachi air conditioners listed in this table use the new generation R32 refrigerant, which increases cooling efficiency by 1.6 times compared to R410A and is extremely environmentally friendly, minimizing the global warming potential (GWP).

Notes on Buying Hitachi Wall-Mounted Split Air Conditioners

Customers/investors need to choose the right model according to their needs and the specifics of each building project. Prioritizing health and technology, Hitachi Home Air Conditioning like the airHome 600 or 500 are the best choices, integrating features such as self-cleaning, filtering, and eliminating 99% of viruses, along with a dehumidification sensor. However, if customers prioritize convenience and remote control, models with built-in Wi-Fi like the airHome 400 are very suitable, allowing them to turn on the unit before arriving home via the airCloud Go app. And in cold climates like Northern Vietnam, choosing a two-way model to utilize heating capabilities in winter saves the cost of purchasing a separate heater.

Calculate and select the appropriate capacity based on the size and characteristics of the room. For bedrooms, a heat load of 600-700 BTU per square meter may be suitable. For living rooms or rooms with many windows, or those facing west, 800-900 BTU per square meter is needed. Choosing the wrong capacity will cause the compressor to run continuously at high temperatures, reducing its lifespan and increasing electricity costs.

Check the SafeGuard protection features if installing the air conditioner in coastal areas or humid environments. Customers should choose Hitachi air conditioners to ensure they have the SafeGuard system, which includes corrosion-resistant fins and a high-voltage circuit board. Additionally, pay attention to the installation locations of the indoor and outdoor units to achieve a quiet operation of 19dB. Avoid installing the indoor unit directly above beds or in a position that blows air directly at people; it should be installed in a location that allows for optimal air circulation. The Hitachi outdoor unit is designed to be rust-resistant and should be placed in a well-ventilated area, avoiding direct sunlight for better heat dissipation.

Choose an authorized Hitachi air conditioner distributor and distribute through official channels. U.P Tech is the exclusive authorized distributor of Hitachi air conditioners in Vietnam, guaranteeing the supply of the latest products. The warranty policy is transparent, and genuine spare parts are provided to customers.

Hitachi wall-mounted split air conditioners are the optimal technical solution for projects requiring high independence while still ensuring durability and reliable operation. By integrating advanced technologies such as FrostWash and the SafeGuard protection system, Hitachi air conditioners optimize long-term operating and maintenance costs for investors. Hitachi air conditioners are not just cooling devices, but also investments in long-term health and comfort.
