In this course, you will explore the principles and practices of engineering and designing district cooling networks. We will discuss the key differences between district heating and cooling networks, examine different pipeline materials (steel and plastic), delve into frequently occurring problems in DC systems, learn about solutions to these, and conduct hydraulic calculations to ensure efficient system operation. Modelling tools will be introduced too.

District Cooling Engineering and Design 

11:00 - 12:00 CET
District Cooling Networks Specificity -
Different Pipe Materials, Pressures and Temperatures

This introductory lecture by Aleksandr Ledvanov (HeatConsult, Estonia) highlights the fundamental differences between district heating and cooling networks. Participants will gain insight into the unique challenges and considerations (like pipeline materials, pressures and temperatures) in district cooling system design. 

12:00 - 13:00 CET
Dynamic District Cooling System Analysis

In this lecture by Mikael Jakobsson (CEO of NXITY), participants will learn how to perform hydraulic calculations for district cooling systems. Topics include flow rates, pressure drops, pipe sizing, and pump selection. Real-world examples and case studies will be used to reinforce hydraulic calculation principles.

13:30 - 14:30 CET
Current Problems in District Cooling Systems

In his lecture, Dr Alaa Olama (Egypt) will focus on critical aspects of modern District Cooling systems, addressing pressing concerns such as over-capacity in DC systems and the challenge of low delta T syndrome. With a keen eye on industry benchmarks, Dr. Olama will elucidate key performance indicators (KPIs) essential for effective system management. Moreover, he will underscore the imperative of adherence to international agreements, notably the Montreal Protocol, in ensuring sustainability and environmental stewardship within the realm of DC engineering.

14:30 - 15:30 CET
