Spoelstra, S. (author)In het CATCH-IT (2012 .. 2015) project is een stoom producerende compressie warmtepomp ontwikkeld waarmee restwarmte van 50˚C tot 80˚C kan worden opgewaardeerd tot lage druk stoom (tot 2,5 barg). De schaalgrootte was 200 kWth en er werd gebruik gemaakt van butaan als werkmedium. De warmtepomp is bij Smurfit Kappa Roermond Papier met het...report 2022

Spoelstra, S. (author)Het totale energiegebruik in Nederland in 2017 bedroeg 3131 PJ. Het gebruik van warmte heeft daar een groot aandeel in. Dit geldt in nog versterkte mate voor de Nederlandse industrie. Figuur 1 toont het energiegebruik van de Nederlandse industrie in 2016. Het finale energetische gebruik bedraag 685 PJ, waarvan 550 PJ (80%) de behoefte aan warmte...report 2019

Spoelstra, S. (author), Tijani, M.E.H. (author), Lycklama a Nijeholt, J.A. (author), Energieonderzoek Centrum Nederland (author)A thermoacoustic heat pump is a promising innovative heat pump technology which can be applied in the industry to upgrade industrial waste heat. The thermoacoustic heat pump consists of a regenerator flanked by two heat exchangers and placed in a gas (helium) filled acoustic resonator. An acoustic wave is generated and sustained by an acoustic...conference paper 2016

Spoelstra, S. (author), Tijani, M.E.H. (author), Lycklama a Nijeholt, J.A. (author), Energieonderzoek Centrum Nederland (author)Efficient use of energy and lower global warming emissions can be achieved by applying heat pumps in the industry. Heat pumps can be used to increase the temperature of industrial waste heat to useful temperature levels. This enables the reuse huge quantities of energy that would otherwise be rejected to the environment. However, widespread use...conference paper 2014

Spoelstra, S. (author), Kleefkens, O. (author), Energieonderzoek Centrum Nederland (author)More than 80% of the total energy use in industry consists of the need of heat in the form of steam at different pressure levels and for firing furnaces. The total industrial heat use together with exothermic heat from chemical reactions is eventually released to the ambient atmosphere through cooling water, cooling towers, flue gasses, and...conference paper 2014

Spoelstra, S. (author), Tijani, M.E.H. (author)Significant energy savings can be obtained by implementing a thermally driven heat pump into industrial or domestic applications [1]. Such a thermally driven heat pump uses heat from a high-temperature source to drive the system which upgrades an abundantly available heat source (industrial waste heat, air, water, geothermal). A way to do this...article 2013
