Abstract: The present invention is directed to a cooling tower that has a cooling tower structure having fill material supported by the cooling tower structure and configured to receive heated process fluid and a motor mounted to the cooling tower structure. The motor has a casing and a rotatable shaft and is sealed to prevent fluids, moisture, foreign particles and contaminants from entering the casing. A fan is connected to the rotatable shaft of the motor. Rotation of the rotatable shaft rotates the fan thereby inducing an upward moving mass flow of cool air through the fill material. A basin is attached to the cooling tower structure for collecting cooled fluid. A fluid distribution system distributes the cooled fluid in the basin.

Abstract: 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 as a 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.
