Distributed Pumping and Control in Heating and Cooling Systems

Carsten Skovmose Kallesøe, Grundfos

Abstract Energy savings is a major issue when designing pump installations. In this presentation, focus is on pump installations for heating and cooling. This could be district heating systems or air conditioning for large buildings. There are two main issues when considering energy savings in these types of systems: Firstly, thermal energy can be saved by decreasing pipe diameters. This calls for larger pump efforts, which is best introduced by distributed pumping. Secondly, there are normally a number of balancing valves in these systems. Energy can be saved by exchanging these valves with pumps, which results in a distributed pumping system. Here we presented problems related to the control of a distributed pumping system over a communication network, with special focus on distributed control and distributed optimization.
