System and method for controlling temperature of industrial processing devices

Abstract

A system and method for controlling the temperature of industrial processing devices includes a central liquid supply having a supply section and a return section and at least one processing device temperature control subsystem in liquid transmission connection with the central liquid supply for generally maintaining the temperature and pressure of liquid being circulated around an industrial processing device at a designated liquid temperature set point which includes a variable-speed pump, control valve and control device which controls the temperature of the liquid in the subsystem by speeding up, slowing down or shutting off the pump to ensure that the subsystem liquid temperature remains approximately equal to the designated liquid temperature set point as determined by the processing device associated with the subsystem and opens or closes the control valve to add or release liquid from the subsystem to maintain the desired pressure within the system.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates generally to systems and methods for cooling industrial processing devices and, more particularly, to a system and method for controlling the temperature of industrial processing devices which includes a central liquid supply having a supply-section and a return section and at least one processing device temperature control subsystem for generally maintaining the temperature of liquid being circulated around an industrial processing device at a designated liquid temperature set point which includes a variable-speed pump, control valve and control device which controls the temperature of the liquid in the subsystem by speeding up, slowing down or shutting off the pump to ensure that the subsystem liquid temperature remains approximately equal to the designated liquid temperature set point as determined by the processing device associated with the subsystem.[0003]2.

AI Technical Summary

Benefits of technology

[0011]The present invention thus provides a substantial improvement over those systems and methods found in the prior art which are designed to provide cooling and heating water to industrial processing devices and systems. First of all, the proposed system has the advantage of considerably reducing the initial equipment cost by replacing expensive solid state chillers with commonly available circulation pumps and accessories. Also, the present system guarantees the desired water temperature and water flow with low energy consumption as it is part of the main water supply system, hence not requiring its own dedicated system for operation thereof. Perhaps most importantly from an operational standpoint, however, is that the present invention greatly reduces required maintenance time and expenses as the components of the system are tried and true pumps, valves and pipes, thus eliminating solid-state chillers which are notoriously prone to breakdowns and failures. It is therefore seen that the present invention provides a substantial improvement over those systems and methods found on the prior art.

Problems solved by technology

During operation, most if not all manufacturing and industrial processing devices release large quantities of heat.

Such a system has higher initial cost, higher energy consumption and very complex control requirements in order to work correctly, and yet these systems are still prone to failure due to their complexity and temperamental equipment elements.
