Title:
SYSTEM FOR POWERING A CHILLER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/020034
Kind Code:
A3
Abstract:
A generator system is operated at variable speeds to provide power to a plurality of motors. The motors are connected to the generator system through a common electrical bus and a disconnect device. The motors each drive a compressor in a chiller system. The chiller system includes a speed and control algorithm, and a data collection network to obtain operating parameters from the associated chiller system. A control system determines a number of compressors to operate and manages the loads of the chiller systems, and determines an operating frequency of the generator required to obtain an operating speed of the motors to maintain a desired temperature of the chiller system.
