Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502, the azeotropic refrigerant binary mixture they are replacing, have been carried. Comparative results show that local flow boiling heat tran ...
Flow boiling experiments for two new non-azeotropic, three-component refrigerant mixtures (HP80 and HP62) and R-502 have been carried out inside a 12 mm bore, horizontal tube. Local boiling coefficients for HP62 are slightly larger that those for R-502 und ...
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 ...
Measurements ith tracer gases were performed, together with more classical temperature and air velocity measurements, on various ventilation systems installed in the test chamber of Sulzer Infra, in Winterthur. The test chamber was arranged to simulate an ...
Heat produced by hybridoma suspension cultures was continuously monitored in a 2-L heat-flux calorimeter. Heat measurements reflected changes in the metabolic state of the culture under different aeration conditions. A highly anaerobic metab. was indicated ...
Measurements of the heat produced by Saccharomyces cerevisiae CBS 426 were used in conjunction with elemental and enthalpic balances to control fed-batch fermns. A proportional control using the ratio of carbon dioxide evolution rate to heat prodn. resulte ...
A modified bench scale calorimeter has been employed to det. the heat generated by various microbial strains growing on a range of different substrates, covering degrees of redn. from 3 to 6.13. The results are analyzed and interpreted in the light of coup ...
The use of the heat-flux calorimeter BSC-81 as a chemostat is described. The technique was applied to study the heat generation rate by continuous cultures of the yeast Kluyveromyces fragilis NRRL 1109 as a function of specific growth rate. The maintenance ...
Four models taken from the literature, which permit calcn. of heats of combustion from elemental anal., are evaluated from a theor. point of view. In order to obtain exptl. values of heat of combustion with a higher degree of accuracy than that in the lite ...
