摘要： The present invention is directed to a direct-drive fan system and a variable process control system for efficiently managing the operation of fans in a cooling system such a as wet-cooling tower or air-cooled heat exchanger (ACHE), HVAC systems, mechanical towers or chiller systems. The present invention is based on the integration of key features and characteristics such as tower thermal performance, fan speed and airflow, motor torque, fan pitch, fan speed, fan aerodynamic properties, and pump flow. The variable process control system processes feedback signals from multiple locations in order control a high torque, variable speed, permanent magnet motor to drive the fan. Such feedback signals represent certain operating conditions including motor temperature, basin temperature, vibrations, and pump flow rates. Other data processed by the variable process control system in order to control the motor include turbine back pressure set-point, condenser temperature set-point and plant part-load setting. The variable process control system processes this data and the aforesaid feedback signals to optimize the operation of the cooling system in order to prevent disruption of the industrial process and prevent equipment (turbine) failure or trip. The variable process control system alerts the operators for the need to conduct maintenance actions to remedy deficient operating conditions such as condenser fouling. The variable process control system increases cooling for cracking crude and also adjusts the motor RPM, and hence the fan RPM, accordingly during plant part-load conditions in order to save energy.
摘要翻译：本发明涉及一种直接驱动风扇系统和可变过程控制系统，用于有效地管理诸如湿式冷却塔或风冷式热交换器（ACHE），HVAC系统，机械式塔或冷却器系统。本发明基于塔式热性能，风扇速度和气流，电机转矩，风扇间距，风扇转速，风扇空气动力特性和泵流量等关键特性和特点的集成。可变过程控制系统处理来自多个位置的反馈信号，以便控制高扭矩，可变速度的永磁电动机来驱动风扇。这种反馈信号表示某些操作条件，包括电机温度，盆温度，振动和泵流量。由可变过程控制系统处理以控制电动机的其他数据包括涡轮机背压设定点，冷凝器温度设定点和设备部分负载设置。可变过程控制系统处理这些数据和上述反馈信号，以优化冷却系统的运行，以防止工业过程中断，并防止设备（涡轮）故障或跳闸。可变过程控制系统警告操作者需要进行维护操作以补救诸如冷凝器结垢的不良操作条件。可变过程控制系统增加了用于裂解原油的冷却，并且在工厂部分负载条件下相应地调节电动机RPM，并因此调整风扇RPM，以节省能源。
