Abstract:

INSIDE project will allow to join forces of several teams among most productive in research in engineering sciences in Romania, establishing a knowledge pole dedicated to support one of the major industrial player in our country which is Renault Technologie Roumanie. This way teams Technical University of Civil Engineering, the National Institute for Aerospace Research "Elie Carafoli", the University of Pitesti and the Technical University of Cluj Napoca will connect some of the most advanced facilities and measuring techniques in Europe in the fields of air distribution, evaluation of Indoor Environment Quality (IEQ), applied fluid mechanics, automation and control, automotive systems design. A series of objectives that would integrate solutions for high indoor environmental quality in vehicles are proposed:

(1) The first project end-objective will be: Developing an experimental real scale facility for studying IEQ and ventilation strategies in the vehicles. The project end-product: a unique national experimental facility dedicated to thermal comfort assessment in vehicles. The expected results are new possibilities of local research development oriented towards the car models from the national Dacia brand.

(2) The second objective is: Reconsidering thermal comfort theory applied to vehicles in order to deepen the knowledge on thermal comfort and its numerical methods of prediction and on the other hand to analyze the real role played by transient environment parameters. The project end-product: new models and evaluation indexes for thermal comfort assessment in vehicles. The expected results are several scientific articles, indexed in ISI Web of Knowledge data base which will contribute to the national prestige of our academic community, and the starting point of developing new standards in the field.

(3) The third objective will be the Evaluation of the impact of multi-zone ventilation and air conditioning strategies on thermal comfort and IEQ in general, on ergonomics and fuel consumption. Several strategies of ventilation and air conditioning – i.e. one zone, multi-zone, of air distribution will be tested along with an optimized fuzzy logic approach for a semi-automatic climate control using variable air flow. Best scenarios for improved comfort and reduced consumption will be assessed. Project end-products: a data base of numerical and experimental results which will allow extrapolating best case scenarios and optimal configurations. Expected results: a Romanian concept car with multi-zone air distribution and semi-automate climate control.

(4) The fourth objective will focus on implementing innovative air diffusion grilles in a Romanian prototype vehicle. The idea behind this objective is to introduce air diffusers with a special geometry allowing improving mixing between the hot or the cold conditioned air introduced in the cockpit and the ambient. The reduced air mass fluxes being introduced in the occupied zone, should uniformly distribute fresh air and conditioning cooling or heating loads in order to achieve thermal comfort and acceptable air quality. The project end-products will be air diffusers prototypes for vehicles. The expected results are: the integration of these prototypes in a Romanian concept car, along with national and international patents, as well as several scientific articles.

(5) The final objective will be a Good Practice Guide for ventilation strategies vehicles and their associated assessment methods. Based on experimental and numerical data from objectives 3 and 4 a coherent series of strategies for designing ventilation systems for vehicles will be proposed. Project end-products: Good Practice Guide for ventilation strategies and thermal comfort assessment in vehicles. The expected results are: the starting point for a new (at least national) standard.

Abstract:

The EST IN URBA project proposes a complex, highly interdisciplinary approach for extending the implementation of solar-thermal systems in urban areas. The project gradually develops novel solutions for: flat-plate solar thermal collectors (FPSTC) – solar thermal arrays (STA) –solar thermal systems (STS) implemented in buildings (facades, balconies, roofs), architectural objects (fountains, decorative walls), parks, focusing on locations with cold/temperate climate.

Novel solutions in the FPSTC are proposed for: the collector’s shape (case geometry), coloured solar absorber plate, multiple (coloured) glazing, ducts, tracking system, tracking algorithm based on thermal response, to avoid overheating. Testing and standardisation methodologies (saline environments) are proposed for the FPSTC and for the absorber plate, and will be submitted for inclusion in the new standard EN-12976.

The STA will be modelled in various geometries of the implemented area. The inter-connection will be optimised for the FPSTCs with the best thermal efficiency, respecting the built integration restrictions (geometry, colour). Tracking mechanisms optimised for STA and tracking algorithms will be developed. Model implementation projects will be developed for the STS with collectors arrays, as transferrable solutions to the market/users.

The laboratory/virtual prototyping optimised solutions will be manufactured as prototypes and tested on indoor and outdoor testing rigs. Small series production will develop the FPSTCs for the façade integrated array, then installed/operated in a functional STS. Maintenance issues focus on façade integrated STS. Cost-performance analysis of the FPSTC and STS allow benchmarking and possible simplifications.

The partnership involves three universities and one industrial partner with broad and complementary expertise in developing solar energy conversion systems. The results will be disseminated by publications in main stream journals (13),and patenting (5)

Abstract:

Our ambitious project aims to extend the research directions already developed at TUCEB in cooperation with the French University of La Rochelle transforming our new created research center CAMBI in a confirmed reference of the international community dedicated to Indoor Ambiental Quality, air diffusion and thermal comfort. One of our objectives is to conceive an advanced thermal breathing manikin prototype which would be able not only to simulate the human body and measure quantities like thermal fluxes exchanged with its environment adapting its thermal response as a function of the environmental stimuli. Once this powerful tool that we want to develop will be functional, we will test several combinations of innovative air diffusers and air diffusion strategies in terms of capability of improving thermal comfort and indoor air quality.

Abstract:

The buildings’ sector is the major energy consumer of the EU's total final energy and energy efficiency is an important point on the agenda of objectives to be attained by EU countries by year 2020. At the same time, we cannot neglect the true purpose of a building: to provide the occupants a comfortable and healthy indoor environment. Indoor environmental quality (IEQ) is a concept that deals not only with thermal conditions but it also goes much further, because it involves air quality, lighting and acoustics. Given the many interactions between building energy performance and IEQ, these two issues must be addressed and researched in a connected manner. Clearly, this research field is facing a big dilemma and the need to find a dual-estimator along with a decision process is mandatory. Considering this panorama, it is highly important to search for solutions of building design that provide the highest benefit for both energy saving and IEQ at the lowest cost. This research project proposal has the main aim to put forward a new methodology to couple IEQ & Energy and to solve the mentioned dilemma with a multi-criteria decision method. This unique approach will be applied for educational facilities with surveys and experimental measurements which are needed for prediction models development and their use in the decision process. The final objective is to find optimum design/rehabilitations solutions for IEQ & Energy in schools.

Abstract:

Indoor air pollution level has the highest influence upon people’s inhaled pollutants. The number of deceased due to the inhaled pollutants overcomes that caused by the cancer. The research field Indoor Air Quality is focusing on the indoor air pollution level and its relation to the outdoor pollution. The importance of this pollutant transfer phenomenon is given by the fact that the air infiltrations and the ventilation system represent the main pollution vectors of the indoor spaces with atmospheric pollutants. Research studies of the pollutant transfer (theoretical and experimental) proved their limitations: high prediction error of the pollutant transfer. We wish to overcome the current limitations) by proposing a new approach for the study of this phenomenon: laboratory experiments of pollutant transfer with a special preliminary treatment of the air introduced for the study. We will divide our project into four stages: Experimental stand design, Experimental study oriented towards one or multiple pollutants, Mathematical modeling and finally the Indoor Environment Quality assessment and control tools. The mathematical modeling stage presents also new approach (new type of mathematical analysis and model form for this research field) that will be suited for the multiple pollutants simultaneous transfer. The project has two main targets: to understand the basic phenomena of pollutant transfer and new ventilation strategies to assure the indoor environment quality.
