Decarbonization of industrial processes by using high-temperature heat pumps is one the most important pillars towards sustainable energy goals. Most are based on standard Carnot cycle which includes an expansion valve leading to irreversible dissipation and energetic losses. Especially for applications, these losses increase significantly, a replacement conventional throttle with ejector, alternative device, partial recovery some pressure lost during expansion, investigated in this paper....
In recent years, the fight against global warming and therefore CO2 reduction have become most important issue for humanity. As a result, volatile sources of energy—like wind solar power—are penetrating electrical grid an increased demand on storage capacities is required. At TU Wien Institute Energy Systems Thermodynamics, Fluidization Based Particle Thermal Storage (FP-TES) working with bulk material as sensible developed. this paper, concept experimental study cold test rig presented. By...
Abstract The pursuit of CO2 reduction targets has increased the need storage capacities for renewable energy or thermal to enhance efficiency industrial processes. To combine benefits latent and sensible systems, concept micro encapsulated phase change material is presented. microparticles are designed work in a high-temperature system considering economic technical points view. Therefore, particles sodium nitrate physio-mechanical coated with polyimide by using spray-drying fluidized bed...
To reduce CO2 emissions in the industrial sector, high-temperature heat pumps are a key technology. This work presents an approach to design such pump system capable of supplying 200 °C sink temperature and capacity approximately 1 MW. Today’s market-available using displacement compressors not suitable for reaching that high temperatures as they need lubricating oil, which is resistant enough. As consequence, this study transcritical cycle two-stage oil-free radial compressor investigated....
Renewables should become more continuously available, reliable and cost-efficient to manage the challenges caused by energy transition. Thus, analytic numerical investigations for layout of a pilot plant concept called Fluidisation-Based Particle Thermal Energy Storage (FP-TES)—a highly flexible, short- long-term fluidised bed regenerative heat storage utilising pressure gradient hot powder transport, thus enabling minimal losses, high densities, compact construction countercurrent...
In the pharmaceutical industry, energy efficiency has played a minor role compared to other energy-intensive industries. However, there is growing recognition of need address environmental concerns. With ambitious climate targets and increasing demand for significant reductions in CO2 emissions, industry now embracing opportunity enhance its sustainability practices. Mainly fossil fuels are used provide process steam at moderate temperature levels about 160-180°C lesser extent hot water or...
