High efficiency

Heat recovery technology

MV6R heat recovery outdoor units can perform both cooling and heating operation simultaneously and independently within the same system, ensuring the maximum operating flexibility for the users. Heat recovery is achieved by diverting exhaust heat from indoor units in cooling mode to areas requiring heating, minimizing the heat exchange with outside environment. As a result, power input and electricity costs are minimized, ensuring the best energy efficiency. In addition, inverter technology allows to adapt precisely to variable capacity loads.

Heat recovery technology VRF MV6R

Independent control of heat exchangers and compressors

Both in cooling and heating mode, the outdoor heat exchanger and compressor are independently controlled to improve performances.
So, in a multiple-unit system, when the compressor of an outdoor unit does not operate due to a lower thermal load, its heat exchanger is kept active to maximize heat exchange surface and efficiency.

Phe (plate heat exchanger) subcooling

Plate Heat Exchanger as a secondary intercooler boosts up refrigerant subcooling and improves 10% energy efficiency.

EMS (Energy Management System)

  • Floating refrigerant temperature for balancing comfort and efficiency

The evaporating temperature (in cooling) and condensing temperature (in heating) are automatically adjusted according to both indoor and outdoor temperature to maximize the comfort and energy efficiency, increasing the seasonal efficiency by 30%

  • Capacity output limitation for shortage of electricity

With the integration of EMS, for projects with limited electricity supply, MV6R can be set to output 40-100% capacity.

Evi (Enhanced Vapor Injection) compressor

Thanks to the vapor injection DC inverter compressor, the MV6R series can run heating mode stably down to -25°C, furthermore strongly increasing the heating capacity especially at low ambient temperature. Compressor is designed to run at 7% modulation minimum, highly improving system efficiency at part load operation.

Wide Application range

Wide capacity range

VRF MV6R series capacity is up to 18HP with a single unit and up to a maximum of 54HP for a single system with a combination of 3 modules, covering all possible applications and building dimensions.

Wide operation range

VRF MV6R can operate in a wide ambient temperature range.
It can operate stably from -15°C up to 52°C in cooling mode and from -25°C to 19°C in
heating mode.
Simultaneous heating and cooling operation is guaranteed from -15°C to 27°C in main
cooling and from -15°C to 19°C in main heating.

High Reliability

Duty cycling

Duty cycling equalizes the running time of the outdoor units in a multiple-unit system and of the compressors in each unit, significantly extending compressor lifespan.

Precise oil control technology

Three stages of oil control technology ensure all outdoor compressor oil is always kept at a safe level, eliminating any compressor oil shortage problems.

  • Compressor internal oil separation.
  • High-efficiency centrifugal oil separator (with separation efficiency of up to 99%) ensures that oil is separated from the discharge gas and returned to the compressors in a timely fashion.

  • Auto oil return program monitors the running time and system status to ensure reliable oil return.

Backup operation

In a multiple-unit system, if one module fails, the other modules provide backup so that the system can continue operating, maintaining up to 4 days interim capacity and allowing time for maintenance or repair while comfort remains guaranteed.

    Anti-corrosion protection

    Outdoor units are given anti-corrosion treatment for non-extreme conditions as standard and can also be customized with heavy anticorrosion treatment on main components for surface protection against corrosive air, acid rain and saline air (for installations in coastal regions) to extend overall useful life. The integrity of the anti-corrosion treatment is ensured by subjecting major components and parts to salt mist testing, moisture and heating testing and light aging testing.

    Please contact your local dealer for further information about customization price and availability.

    Refrigerant cooling pcb

    The MV6R series uses refrigerant cooling technology to cool the electric control box. It decreases the average temperature of electrical control components by about 8 degrees,
    guaranteeing the stable and safe running of the control system.

    Auto snow-blowing function

    The innovatively designed auto snow-blowing function enables the outdoor unit to prevent the accumulation of snow by itself.

    Dust-clean function

    The innovatively designed dust-clean function enables the outdoor unit to prevent the dust by itself.

    Enhanced Comfort

    Night silent mode

    The night silent mode feature includes various scheduling options that can be used to reduce noise levels when low noise operation is required: only during night hours or continuously, and with different noise reductions levels limiting only maximum fan speed or compressor speed also.

    Enhanced heating capacity

    Thanks to the vapour injection DC Inverter compressor, heating capacity can achieve 100% output when the ambient temperature is down to -5°C and 90% output when ambient temperature is down to -15°C.

    Continuous heating during defrost

    As an alternative to the traditional defrost technology performed reverting the refrigerant cycle, in a multiple-units MV6R system it is possible to keep heating by defrosting alternatively and independently the heat exchangers of different units. Thus, it is possible to supply continuously heating without stopping for defrost operations.

    Easy installation and service

    Automatic refrigerant charging and recycling function

    Automatic refrigerant charging function make the installation and service easier and more efficient, automatically collecting refrigerant from the tank and stopping the operation when exact refrigerant charge is done. Automatic refrigerant recycling allows to recover and accumulate the refrigerant inside the outdoor unit or on indoor units side automatically when required before repairing, strongly simplifying the technical intervention.

    Auto addressing

    Outdoor unit can distribute addresses to indoor units automatically.
    Remote and wired controllers can be used to query or modify each indoor unit’s address.

    Suitable for any application

    Maximum application flexibility

    In addition to simultaneously heating and cooling different spaces via different indoor units belonging to the same system, MV6R series can manage fresh air processing units (A), beside high temperature hydronic modules to supply hot water up to 80°C (B), or air handling units through specific kits (C). According to the different combinations of units connected, the system can manage up to 200% of outdoor units’ capacity.

    Fan esp up to 80 pa

    Fan motor can be set to provide an external static pressure up to 80 Pa, facilitating the installation of the unit in technical rooms or in areas where the proper airflow cannot be ensured, by installing ducts and directing the air towards the outside.

    Refrigerant leak detection function

    Refrigerant leakage detectors can be managed through specific input/output contacts to automatically stop the system operation and to display the malfunction on remote controllers or via possible luminous signal and activating also specific exhaust fans if needed
