FR-E720-0.4KSA MITSUBISHI Central unit

Product  Description：

Mitsubishi Electric central air conditioning systems, primarily represented by the CITY MULTI VRF (Variable Refrigerant Flow) series, are engineered to provide high-performance climate control for both residential and commercial environments. These systems utilize advanced inverter technology to distribute heating or cooling independently to multiple zones using a single outdoor unit. The design focuses on high efficiency, architectural flexibility, and user comfort by adapting the refrigerant flow to the specific demand of each room.

Technical Parameters

The technical specifications of Mitsubishi central units vary based on the specific model and building requirements. Generally, the capacity for air-cooled heat pump systems ranges from 22 kW to over 150 kW. The systems are designed to handle significant vertical height differences, often up to 90 meters between the outdoor and indoor units, with total piping lengths reaching up to 1000 meters in larger configurations.

Most modern units utilize R32 or R410A refrigerants, which are selected for their thermal efficiency and lower environmental impact. The outdoor units feature high external static pressure settings, typically up to 80 Pa, allowing them to be installed behind louvers or in restricted spaces without compromising airflow. Sound pressure levels are kept exceptionally low, with some indoor units operating at just 19 dB(A), and outdoor units featuring specialized low-noise modes for nighttime operation.

Product Advantages

One of the primary advantages of Mitsubishi central units is their Energy Efficiency. By using inverter-driven compressors, the system only consumes the precise amount of power needed to maintain the target temperature, significantly reducing electricity bills compared to fixed-speed systems.

The Design Flexibility is also a major highlight. A single outdoor unit can connect to a wide variety of indoor unit types, including wall-mounted, ceiling-recessed cassettes, floor-standing, and ducted units. This allows the system to blend seamlessly into any interior decor. Additionally, the 3D i-see Sensor technology can detect the number and position of people in a room to adjust airflow automatically, ensuring direct or indirect cooling based on user preference.

Important Precautions

To ensure long-term reliability, it is critical that the system is installed by certified HVAC professionals who are familiar with VRF technology. Incorrect piping or improper refrigerant charging can lead to reduced efficiency or compressor failure.

Regular maintenance is essential, specifically the cleaning or replacement of air purification filters every few months, depending on the environment. For units installed in coastal or high-pollution areas, it is recommended to use models with anti-corrosion treatment on the heat exchangers. Additionally, users should avoid blocking the airflow of both indoor and outdoor units to prevent the system from overworking and triggering safety shut-offs.

Product Applications

Mitsubishi central units are highly versatile and suitable for a broad range of applications. In the Residential Sector, they are ideal for luxury villas and multi-story apartments where individual room control is desired.

In Commercial Settings, they are widely used in offices, hotels, and retail stores because they can provide simultaneous heating and cooling in different zones through heat recovery technology. They are also frequently applied in Critical Environments such as hospitals and data centers where precise temperature and humidity control are mandatory for safety and equipment performance.
