Energy efficiency of pumps and heat exchangers

Charbonneau, Talwyn January 2021 (has links)
Energy efficiency is a growing field that concerns more and more companies, individuals as well as governments in order to reduce costs and use less energy for a more sustainable development. Engie is no exception and values energy efficient projects. In this paper will be documented three energy efficiency related projects that I carried out during my five month end of studies internship. This work spans different topics, the parallel operation of hydraulic distribution pumps, the modeling of an heat exchangers as well as pid calculations for a dedicated ehating network. We delve into the technical aspect of each subject before introducing the tools developed, with some of their results. / Energieffektivisering är ett växande område som berör allt fler företag, privatpersoner såväl som myndigheter för att minska kostnaderna och använda mindre energi för en mer hållbar utveckling. Engie är inget undantag och värdesätter energieffektiva projekt. I den här artikeln kommer tre energieffektivitetsrelaterade projekt att dokumenteras som jag genomförde under min fem månder långa praktikperiod. Detta arbete spänner över olika ämnen, parallelldrift av hydrauliska distributionspumpar, modellering av en värmeväxlare samt pid-beräkningar för ett dedikerat värmenätverk. Vi fördjupar oss i den tekniska aspekten av varje ämne innan vi introducerar de utvecklade verktygen, med några av deras resultat.

Teplovodná deska s řízeným teplotním polem / Thermal conductive plate with controlled thermal field

Masár, Pavol January 2010 (has links)
This work deals with design of thermal source of panel shape for scientific biological application. Panel has adjustable surface temperature and thermal gradient. The first part of this work concern with design and numerical modeling of the thermal system, application of materials and arrangement of thermal and cooling devices – Peltier elements. Second part of this work is about construction of the panel and experimental measurement.
