  • 175m equivalent pipe length with a total system pipe length of a 1000 metres.  When the outdoor unit is located above the indoor unit the standard height difference is 50m. When the outdoor unit is located below the indoor unit, the standard height difference is 60m.
  • Heating and cooling to all commercial premises and many other industrial applications. It enhances the indoor environment and creates a basis for increased business prosperity. Whatever the air conditioning requirement, a Gree  indoor unit will provide the answer. GMV-R air conditioning can be supplied via 5 different indoor unit models in a total of 53 variations.

  • GREE GMV intelligent controls and modulating valves can deliver the required capacity, according to the load variation from
    10% to 100%.
    The intelligent controls and modulating valves limit or increase the cooling capacity dynamically, so humidity and temperature are kept in the comfort range.

    Electronic expansion valves respond to the charges in load of indoor units and control the flow rate of refrigerant. In this way, we can get a nearly constant room temperature with the GMV system without common temperature fluctuation that occurs with a conventional ON/OFF control system. The precise PID controls maintain the room temperature within +- 0.5  C of the set temperature.

  • Central Control Available (provided with weekly time function)
    Network monitoring system available.
    Wireless remote controller or wired controller for indoor units.
    Diagnostic software for service purposes.

  • Temperature, time and airflow can be controlled individually
    in each room by the digital technology within the indoor and outdoor
    units.

  • Rm series and Pdm series are modularly designed so that a maximum of 4 basic modules can be freely combined together to achieve max capacity of 72HP (201Kw). With advanced controlling, the outdoor modules have no differences so there is no need to appoint master or slave units.

  • Due to the high-efficiency of the DC inverter fan motor, the outdoor units are highly efficient and very quiet.
    The ESP (external static pressure) is up to 50Pa, which means that the hot air exhaust can be ducted without a fan.
    (Note: Only specified models are equipped with a DC inverter fan motor, the others have an AC inverter motor). For more details please contact  ACD Sales department.

  • The central controller can control 64 communication modules, which can connect with up to 1024 indoor units. The system can central control all units, a single control, or select multiple indoor units.
    2. Several displays and functions including: error code display, auto detect display, indication of operation state, time, clock, and self diagnostic function.

  • The communication net that is formed by the central controller and several communication modules can use a communication wire that is up to 1000 metres of 2 core cable (without using communication interrupter).
