Energy efficiency facets: innovative district cooling systems

District Heating and Cooling Enable Efficient Energy Resource Utilisation

Development of Practical Drag Reduction System for District Cooling Systems

In this report, results from the project, proposed in the original research plan are presented. 10 surfactant systems effective as drag reducing agents (DRA’s) in efficient district cooling, including four commercial cationic surfactants, one commercial and three novel synthesized zwitterionic surfactants, one commercial nonionic surfactant and one zwitterionic(synthesized)/anionic surfactant m...

Distributed High Capacity Cold Storage in District Cooling Systems

The demand for comfort cooling is increasing very quickly around the world, e.g. due to improved living standards. At present, air-conditioning is consuming large amounts of electricity, often during hours of peak power demand. Also, a major part of the electricity around the world is produced from fossil fuels, and thus the threat of global warming, caused by increasing emissions of carbon dio...

Comfort, Energy Efficiency and Adoption of Personal Cooling Systems in Warm Environments: A Field Experimental Study

It is well known that personal cooling improves thermal comfort and save energy. This study aims to: (1) compare different personal cooling systems and (2) understand what influences users' willingness to adopt them. A series of experiments on several types of personal cooling systems, which included physical measurements, questionnaires and feedback, was conducted in a real office environment....

Optimize Energy Use in Industrial Cooling Systems

Chilled-water cooling systems used in the chemical processing, petroleum manufacturing, and power generation industries remain fertile ground for electrical energy savings. This is in spite of the lack of attention given to industrial cooling by energy auditors and rebate program designers. This article discusses the large energy savings that can be achieved through hardware and operational imp...
