US 2009/0020173 A1 · INDUSTRIAL PROCESS EFFICIENCY METHOD AND SYSTEM

Abstract

This Invention relates to an industrial process efficiency method and system and relates particularly to a method and system for improving the efficiency and performance of any industrial process when loading is at maximum capacity or under maximum capacity. The system incorporates plurality of identical or similar capacity motor-driven pumps to move liquids, slurries, gases and other fluid or fluid-like material at equal reduced speed or at almost equal reduced speed or at similar reduced speed in lieu of the original/traditional designed comparative inefficient pumping arrangements, thereby, to provide the optimum or same flow capacity with respective to the original pumping arrangement's operating flow capacity. In accordance with the method and system of this invention, significant energy saving can be achieved. Furthermore, the method and system can act responsive to the loading signals or some other reference from which loading can be inferred, thereby a greater extent of energy saving can be accomplished accordingly. The present invention is directed to methods and systems of improving the overall operating performance and efficiency of movement of fluids such as in HVAC systems, paper processing, water and or sewage treatment plants, or any other system that incorporates fluid pumping and the like.

Dependent claims

An industrial fluid circulating system having one or more fluid circulation circuits, the system including:

a plurality of pump means to circulate the fluid through each of said circuits,
motor means driving each pump means,
load sensing or detecting means to sense operating loads on the system and the circuits, and
speed control means to vary the speed of said motor means to thereby vary the pumping capacity of each pump means in response to the detected load on the system.

1 more element

An industrial fluid circulating system having a plurality of fluid circulation circuits comprising:

a variable capacity, compression type, chilled fluid cooling system comprising:
a single circuit chilled water system including:
at least two chilled water pumps;
a chiller with evaporator operatively coupled to a numbers of cooling loads and a suction line leading back to said chiller;
water passing through said chiller in a heat exchange relationship and being cooled;
motor means for driving said chilled water pumps;
a variable-speed drive circuit for powering each of the motor means to vary the speed of the chilled water pumps;
means for sensing the temperature of water leaving said chiller;
and
means for controlling the variable-speed drive circuit in response to the present load on a system compressor so as to regulate operation of the said at least two chilled water pumps running at equal reduced speed or at almost equal reduced speed or at similar reduced speed simultaneously in response to the load on the compressor.
