Highly efficient operation

VU-V provides environmentally conscious, high-efficiency operation while ensuring comfort.

Highly efficient operation

Energy saving technology that boosts operation efficiency

Energy saving technology that boosts operation efficiency

1. Powerful large propeller fan

The fan uses CFD* technology to achieve both high performance and low noise operation.

2. 3-phase DC fan motor

3-phase DC fan motor

The use of a DC fan motor with sophisticated driver control improves energy efficiency substantially. In addition, this motor operates quietly.

3. Sine-wave DC inverter control

Sine-wave DC inverter control

High-efficiency is realized by the adoption of reduced switching loss IPM.

4. Subcooling heat exchanger

Subcooling heat exchanger

High heat exchange efficiency is achieved by using an internal projection-shape double-pipe construction.

5. Scroll compressor

Scroll compressor

The combination of a scroll compressor with a wide rotational frequency range from 15 to 120 rps and our proprietary sensorless sine-wave control that smoothly controls the input power into the motor achieves more energy-efficient and quieter operation.

Refrigerant flow control

Refrigerant flow control

Refrigerant flow is automatically adjusted within the heat exchanger depending on airflow balance.

If the outdoor air intake airflow of the left and right heat exchangers is different, the system automatically monitors the refrigerant status and adjusts the refrigerant flow rate of each heat exchanger to prevent loss of thermal efficiency.

8-16 HP models

1. 4-face heat exchanger

4-face heat exchanger

2. Front intake port (Corner cut air inlet structure)

In multiple outdoor unit installations, the unique front intake design improves airflow into the heat exchanger.

Reducing outdoor unit installation space

A single outdoor unit can handle air conditioning up to 22 HP. This reduces reduce installation space and the number of outdoor units required.

Reducing outdoor unit installation space

High external static pressure

High external static pressure

The outdoor unit’s external static pressure is adjustable up to 110 Pa (18/20/22 HP).

This facilitates mechanical room and hood installations.

Piping flexibility and safety measures

Piping flexibility and safety measures

RB Unit includes Shut off valve kit function

In addition to switching between cooling and heating modes, an electronic expansion valve function has been added to shut off the refrigerant. This eliminates the need to install a separate shutoff valve kit, reducing costs and improving installation efficiency.

No need to use Shut off valve kit for heat recovery use, provide simple installation

Enhanced disaster safety measures

Piping flexibility and safety measures

It features a power backup function for use during power outages. Furthermore, to prevent refrigerant leakage during power failures, the shut-off valve closes when a power outage occurs.

Extended operating range for ambient temperature

Extended operating range for ambient temperature

*In the case of heat recovery .

Extended operable ambient temperature enables an offer to different regions with different temperature condition.

Rotation defrosting

Rotation defrosting

Heat Recovery type & additional type only

Rotation defrosting uses heat from other units instead of room heat, minimizing temperature drops and maintaining comfort during defrosting.

Environmentally conscious with low-noise mode

Environmentally conscious with low-noise mode

*When using this function, cooling and heating performance may decrease.

5-steps low-noise modes are available.

This allows for detailed noise control in various external environments.

Safety measures in case of refrigerant leak

Safety measures in case of refrigerant leak

*It is necessary to connect the required products according to the floor area of the space requirement and the amount of system refrigerant.*2: The operation varies depending on the type of remote controller.

Indoor units compatible with R32 refrigerant are equipped with a refrigerant leak detector. (Some indoor units require optional purchase.) Depending on the conditions of the room where the indoor unit is installed, countermeasures can be implemented using detection equipment.*1 When activated, the refrigerant leak detector triggers the “Shut off valve kit” and “Wired Remote Controller” to operate simultaneously. This notifies the user or administrator of a refrigerant leak while simultaneously stopping refrigerant circulation.
