Why Do Many Small Projects Choose Hitachi RAC Systems?

In Vietnam, the trend for smaller buildings such as houses, apartments, small offices, or shops is gradually shifting from using Chiller systems to Hitachi RAC systems. Hitachi RAC systems (Room Air Conditioners – wall-mounted or residential air conditioners) are becoming a popular choice thanks to advanced Japanese technology, offering convenience, cost savings, and easier installation for personal use, making them more suitable than VRF (Variable Refrigerant Flow) systems, which are typically designed for larger buildings.

U.P Tech – the exclusive distributor of Hitachi air conditioners in Vietnam with over 25 years of experience – is proud to be a supplier of genuine Hitachi RAC systems in the Vietnamese market, helping families and small businesses enjoy cool, clean, and healthy spaces, leading the way in advanced technology without incurring high costs.

What is the Hitachi RAC system?

The Hitachi RAC system These are residential air conditioners (wall-mounted or semi-wall-mounted), designed for single spaces or several small rooms. Popular models incorporate advanced Inverter technology and FrostWash automatic cleaning/air filtration, resulting in fast, comfortable cooling and energy savings.

Note: RAK: Is the code for the indoor unit (evaporator) - RAC: Is the code for the outdoor unit (condenser).

The Hitachi RAC system is divided into main types to suit a variety of consumer needs:

• Single Zone refers to a single-zone system: consisting of one outdoor unit and one indoor unit, suitable for small spaces or single rooms such as bedrooms or offices. This is a cost-effective solution that is easy to install and operate.
• Multi Zone refers to a multi-zone system: consisting of one outdoor unit and multiple indoor units, allowing for independent temperature control in each room. This is an ideal choice for apartments, townhouses, or offices that require separate climate control for multiple areas.

This demonstrates that, with its flexible and advanced technologies, the Hitachi RAC system effectively meets the needs of both individual users and large spaces, providing optimal comfort, convenience, and high efficiency.

• For homes, detached houses, and apartments (1-4 bedrooms), it is preferred for use in living rooms, bedrooms, and offices, keeping the space cool and comfortable.
• In small office spaces, shops, and showrooms, each area can have its own temperature control, creating comfort for employees and saving energy.
• For serviced apartments, hostels, homestays, or small-scale civil constructions, the Hitachi RAC system is considered a cost-effective solution, saving installation space while enhancing the aesthetic value of the space.

Thanks to its flexible adjustability and advanced technology, the Hitachi RAC system is the top choice for those seeking a modern, durable, and energy-efficient air conditioning system.

Why do many small projects choose Hitachi RAC systems instead of VRF systems?

VRF is a central inverter air conditioning system, suitable for large buildings, multi-story offices, or hotels requiring flexible zoning and high capacity. However, for smaller projects (under 100-200m², 3-5 rooms), the Hitachi RAC system is superior for the following reasons:

• Significantly lower initial investment cost: VRF requires a large central outdoor unit, long copper piping, and a complex control system, resulting in high installation costs. In contrast, the Hitachi RAC system only requires one outdoor unit for one indoor unit (or a simple multi-split system), saving 30-50% on costs compared to mini VRF systems for the same small scale.
• Simple, quick, and minimally invasive installation: No need for large wall excavations, long piping runs, or complex construction like with VRF. Hitachi RAC systems are easy to install in homes, apartments, or small offices, with installation taking only 1-2 days, ideal for those who want to minimize disruption to interior design or daily operations.
• Energy saving and flexible operation for small needs: The DC Vector Inverter technology in Hitachi RAC systems saves up to 60% on electricity, precisely adjusting power output according to room size. For small buildings where heat load varies from room to room, RAC allows independent on/off control without waste like VRF (more suitable for large, stable loads).
• Focus on health and clean air with exclusive FrostWash technology: FrostWash™ technology freezes the evaporator coil to -15°C and then melts, washing away dirt, bacteria, and mold, maintaining performance and fresh air without the need for frequent cleaning. This is a significant advantage for families with young children or the elderly, while VRF systems often focus on overall performance rather than detailed self-cleaning.
• Aesthetic design, quiet operation, and ease of use: The slim, modern wall-mounted indoor unit suits any interior space. GoodSleep mode, controlled via mobile app (depending on model), and multi-stage air filtration with virus/bacteria protection provide optimal comfort for small homes. Easy maintenance and low costs for small projects; Hitachi RAC systems require simpler maintenance than VRF systems (fewer complex components), reducing the risk of malfunctions and long-term repair costs.

Hitachi RAC systems save costs while ensuring high performance, clean air, and Japanese durability.
