Combining cooling of underground railways with heat recovery and reuse

Integrated Liquid Cooling with Heat Reuse: A New Generation of Energy Efficient Computers and Photovoltaics

The topic of this doctoral thesis is energy efficient electronic cooling using hot water as coolant. The aim of the work is to provide a viable solution to reduce the energy spent for cooling supercomputers and allow energy reuse for secondary applications. A transition from air cooling to single phase liquid (water) cooling is proposed to master the challenge of ever increasing heat dissipatio...

Reuse of Refinery Treated Wastewater in Cooling Towers

In this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. A polyamide spiral wound RO membrane followed by three filters as RO pretreatment (two activated carbon and one cartridge filter) and samples of Tehran refinery treated waste water have been used. The effect of operating conditions such as pressure differ...

Nitrogen recovery and reuse

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

iDataCool: HPC with Hot-Water Cooling and Energy Reuse

iDataCool is an HPC architecture jointly developed by the University of Regensburg and the IBM Research and Development Lab Böblingen. It is based on IBM’s iDataPlex platform, whose air-cooling solution was replaced by a custom water-cooling solution that allows for cooling water temperatures of 70◦C/158◦F. The system is coupled to an adsorption chiller by InvenSor that operates efficiently at ...
