The simulated cooling plant equips an office building whose maximum cooling demand is about 5 MW. To meet this load, the cooling plant uses five cooling towers, four twin-screw chillers and four encapsulated ice storage tanks. The simulation of the cooling plant is carried out with the software TRNSYS. To perform the simulation, the system components are first modeled and identified on the basis of the information given by the equipment manufacturers and the installers. Once the parameter identification of the components is done, TRNSYS is used to simulate the cooling plant in each operating mode. This paper focuses on two operating modes : the pure discharging and the direct production with possible discharging. For these modes, a control strategy was developed during the cooling plant design phase. This paper discusses the impact on the plant performance of changes brought to the designed control strategies [less ▲]

The aim of the present paper is to test and compare some mathematical discrimination or pattern recognition methods in order to identify one among three air pollution sources.The basic material in this work are : - the standard gas chromatography/mass spectrometry analysis with concentrations values for different chemical compounds observed at about hundred sites in iron and steel industries : either coking plants, or cold rolling mills, or coil-coating plants. - the odours levels, measured by the method of dilution at the threshold. Generally speaking, coil-coating plants emit more chemical compounds than two others, however olfactive threshold is about the same in the three cases. Sums of compounds concentrations for different chemical families (e.g. alkanes, alcohol's, phenols, ...) are calculated and used for the mathematical treatments. Because the frequency histogram of the observed concentrations has a log normal distribution, logarithm of concentration is chosen as operating variable instead of concentration itself. The stepwise multiple linear regression is used in order to express the dilution factor at the olfactory perception threshold as a linear combination of the logarithm of concentrations. Results show that this factor can be estimated quite well on the basis of the concentrations of compounds belonging only to three chemical families. Nevertheless, these families differ following the emission source. To perform the optimal odour description of the three types of industrial plants a larger set of compounds families should be examined in a first step. Factor analysis is used with the aim of regrouping observed variables that are linked together in the plane of the first two factors. The representation of observation points is then superposed on this scheme. Some variable clusters are observed. The method, applied to the whole variables set, classes rather well the observations : the three emissions sources are well discriminated. Cluster analysis, discriminant analysis and neural network have also been used, but only with three variables common to all installations : concentrations of alkylbenzenes, polycyclic aromatics and alkanes. Cluster analysis is not a "supervised method". That means that it is free to create itself some groups showing similar behaviour with regard to the observed variables. Indeed, results show that cluster analysis does not allow to recognise the emission source. In discriminant analysis, target groups membership is provided for each set of variables values : it is a supervised method. The classification functions so deduced allow to discriminate quite well the three industrial plants and to predict the emission origin. A total of 87 % of the observations are correctly on the basis of the classification functions. Neural network approach, with backpropagation algorithm, is a so-called "pattern recognition technique" and is also a supervised method. It provides still better results than statistical ones. After the learning phase, the network is able to identify correctly 99.5 % of observations from 95.5 % the training set.The concentrations of compounds belonging to three chemical families, combined with a pattern recognition technique based either on discriminant analysis, or on neural network, prove to be efficient for recognising the source of odorous gaseous effluents. For the data set considered in this paper, the neural network exhibits better classification performances than discriminant analysis, but its learning phase is slower. However, applying one method or the other for further recognition of unknown patterns is quick and easy. [less ▲]

Il s'agit du chapitre 14 d'un ouvrage collectif consacré à la mesure et à l'instrumentation. Ce chapitre présente plusieurs aspects de la démarche de la mesure dans l'environnement. Il explicite les aspects méthodologiques propres à l'environnement et les méthodes de mesure qui en découlent, notamment les bio-capteurs, les bio-indicateurs, l'utilisation de l'homme comme instrument de mesure, … Il balaye les différents secteurs de l'environnement -air, eau, odeur- et montre comment le modèle et la théorie de l'analyse des systèmes peuvent être considérés comme des outils performants de surveillance d'atmosphères polluées ou de confort thermique dans les bâtiments.

The Fondation Universitaire Luxembourgeoise (FUL) building (completed in 1986) has been selected as a Belgian candidate for participation in the IEA (International Energy Agency) Task XI project devoted to passive solar commercial buildings. Therefore, an evaluation methodology has been set up and a monitoring plan has been defined and performed. Together with this experimental investigation, intensive computer simulation work has defined an optimized design of the building. The main results show that the recorded performance can be improved to an extent of 15% energy savings, which yields a correct performance for a passive solar building in the temperate maritime Belgian climate.
