    """Variable Refrigerant Flow (VRF) heating/cooling system (with no ventilation).

    Each room/zone receives its own Variable Refrigerant Flow (VRF) terminal,
    which meets the heating and cooling loads of the space. All room/zone terminals
    are connected to the same outdoor unit, meaning that either all rooms must be
    in cooling or heating mode together.

    Args:
        identifier: Text string for system identifier. Must be < 100 characters
            and not contain any EnergyPlus special characters. This will be used to
            identify the object across a model and in the exported IDF.
        vintage: Text for the vintage of the template system. This will be used
            to set efficiencies for various pieces of equipment within the system.
            Choose from the following.
