3 reasons to choose Hitachi Mini VRF Set Free for your air conditioning system
Connect multiple indoor units and optimize installation space
For buildings with multiple rooms requiring air conditioning, equipment placement must be carefully planned to meet cooling demands while optimizing the space allocated to outdoor units. Hitachi Mini VRF Set Free allows multiple indoor units to be connected to a single outdoor unit within the same system. The HNRQ series supports 2 to 18 indoor units, while the HNSKQ series supports 2 to 10 indoor units, depending on the model and system configuration.
In addition to supporting multiple indoor units, the outdoor unit features a compact design that helps optimize the space available for equipment outside the building. This is an important consideration for projects with limited installation space or those requiring the overall architectural design to maintain a high level of visual appeal. These advantages make the system worth considering for townhouses, villas, offices, and commercial buildings with multiple air-conditioned areas.

Outstanding cooling and heating efficiency
Equipment efficiency is one of the key factors to consider when selecting an air conditioning system. For Hitachi Mini VRF Set Free, the two series, HNRQ and HNSKQ, have different Energy Efficiency Ratio (EER) and Coefficient of Performance (COP) ratings.
- Hitachi Mini VRF HNRQ: Cooling EER of up to 4.5 and heating COP of up to 4.59.

- Hitachi Mini VRF HNSKQ: Cooling EER of up to 4.0 and heating COP of up to 4.2.

EER indicates cooling efficiency, while COP indicates heating efficiency under the respective test conditions. These indicators provide investors and design consultants with additional information to evaluate energy efficiency when selecting equipment.
In addition, Hitachi has introduced improvements that reduce standby power consumption to below 5 W. This feature is designed to limit electricity consumption when the system is not operating in its primary mode. However, actual energy consumption depends on the cooling load, environmental conditions, equipment configuration, and operating mode. Therefore, system selection should be based on the technical calculations for each individual project.
Flexible design to support system installation and maintenance
Every project has different floor plans, structural characteristics, and installation conditions. Therefore, flexibility in piping arrangements and ease of technical inspection are important factors to consider when selecting a central air conditioning system.
Hitachi Mini VRF Set Free HNRQ & HNSKQ is designed with multiple piping connection directions on the outdoor unit, including the front, right, rear, and bottom. This design provides additional options for routing pipes according to the actual conditions of each project.
In addition, the system features a display on the outdoor unit that supports monitoring of certain operating information, such as temperature, pressure, and equipment status. The service panel also supports error code display, error information checks, and operating status monitoring, helping facilitate inspection and diagnostics at the installation site.

Which projects are suitable for the Hitachi Mini VRF Set Free system?
With its ability to connect multiple indoor units, compact outdoor unit design, and flexible piping configurations, Hitachi Mini VRF Set Free HNRQ & HNSKQ can be considered for various types of projects, depending on the cooling load and technical requirements.
Townhouses and villas
Townhouses and villas with multiple bedrooms, living rooms, or living areas often require air conditioning at several locations. A Mini VRF system can connect multiple indoor units to a single outdoor unit, helping optimize equipment placement according to the building's layout.
Office buildings
For offices with multiple functional areas, such as meeting rooms, management offices, and workspaces, a VRF system allows indoor unit locations to be designed according to the needs of each area. Model selection should be based on floor area, cooling load, and the overall system design.
Hotels and serviced apartments
Projects with multiple guest rooms require careful planning for outdoor unit placement, piping, and indoor units. Hitachi Mini VRF Set Free can be considered during the system design process when its capacity range and technical limitations meet the project's requirements.
Retail stores, showrooms, and commercial buildings
For commercial spaces with multiple areas requiring air conditioning, a Mini VRF system can be an option worth evaluating during HVAC design. Its ability to connect multiple indoor units provides greater flexibility in equipment placement according to the layout of the premises.
The choice between HNRQ and HNSKQ should be based on the total cooling load, number of indoor units, piping length, and actual installation conditions. The system should not be selected solely on the basis of building area or the number of rooms without proper technical calculations.
