High Efficiency Operation (V Series)

High efficiency operation system
    Effective use of the heat exchanger of other outdoor units
    This system takes advantage of the features of the multi type outdoor unit

    The heat exchanger is operated at maximum efficiency by effectively using the heat exchanger of each outdoor unit reciprocally.

    Example

    The larger heat exchanger than the capacity of a compressor is used in each outdoor unit. (V series)


    Conventional method



    High Efficiency Outdoor unit

    Large propeller fan
    A newly designed fan is adopted for achieving higher performance and reducing the noise level.

    Sine-wave DC Inverter Control
    By adopting Sine-Wave DC Inverter Control for smoothing the motor running, energy saving and high efficiency operation are realized.

    DC inverter + Scroll compressor
    By combining the DC inverter controlled scroll compressor with the constant speed scroll compressor, an operating system of energy saving and high efficiency is realized.

    Equipped with DC inverter scroll compressor
    High efficiency
    All key features of the outdoor unit result in a higher level of COP

    We have achieved cooling COP is 3.2 and Heating COP is 3.7.
    • The data refers to a 10HP outdoor unit.
    • "COP" is the coefficient of performance
      [= capacity (kW) 惻input power (kW)].

    * COP values are base on our own testing method.
