Abstract

A kind of new regulative and control technologies is proposed in this article, which is used to adjust the temperature and cool of supply water reversely from air conditional terminal equipment, second cooling station to centralized cooling station in tune. The cold energy regulative technology of constant flow rate and variable temperature difference with self tuning PID algorithm based on expertise is used to increase the supply chilled water, furthermore improves the efficiency of refrigerating compressor. This method has been put into operation with district cooling system in Guangzhou University town with great satisfactory and would be widely used in the future.
