Method for Reducing Energy Consumption of Pumps in Multi Source District Heating and Cooling System

Abstract

We propose a method for reducing energy consumption of pumps in multi source district heating and cooling system. The method consists of an optimization technology and a control technology to compensate for modeling error. The proposed method automatically modify a parameters of the optimization model according to an actual valve aperture of a target system and prvent heat supply shortage or oversupply. The simulated results show the method is able to reduce 11.7% of the total energy consumption of pumps.
