In the previous issue of the IEA Heat Pump Centre Newsletter (Vol, 12, No.3, pp. 29-31), an article by these authors described the use of pinch analysis (also known as pinch technology) in a buildings application. This article describes a similar procedure ...
Pinch analysis is a powerful analysis and design methodology for the integration of thermal processes. Although originally developed for and applied to continuous industrial processes, pinch analysis can be equally beneficial when applied to buildings. In ...
For the most part, district heating demands can be met by an appropriate integration of cogeneration and heat pumps units provided that advantage is taken of the fact that many urban regions are concentrated around surface waters. Such an integration resul ...
The H fragment produced in the photodissocn. of water (H2O -> H + OH) is lighter than the lattice atoms and a local heating occurs over long time scales and large spatial regions. Therefore, use of a continuum model for the lattice is justified. The local ...
JET was extensively modified in the 1992/93 shutdown. The new pumped divertor and many new systems were brought into operation early in 1994. Operations have progressed to 4MA plasma current and, with substantial additional heating, H-mode confinement resu ...
The combined sugar and ethanol production process from sugar cane is a paradigmatic application for energy integration strategies because of the high number of hot and cold streams involved, the external hot utility requirement at two temperature levels fo ...
Geothermal energy is heat energy generated and stored in the Earth. With the awareness of the society about environmental issues, geothermal power is developing worldwide. It is cost-effective, reliable, sustainable, and environmentally friendly but has hi ...
The paper describes two 3.9 MWth ammonia heat pumps of a District Heating plant which also includes two gas turbine cogeneration units. After nine years of reliable operation the heat pumps still show excellent coefficients of performance of above 4.1. Thi ...
