Abstract:

Buildings account for 36% of worldwide energy consumption, with the Heating Ventilation and Air Conditioning system representing up to 55% of a building's consumed energy.

The most thermally inefficient building envelope elements are the glazing units, causing (28-36) % of the total heat inputs during summer.

The project aims to study the efficiency of translucent phase change material (PCM) layers in the structure of photovoltaic (PV) skylights, that provide a level of daylighting.

PCMs store high amounts of thermal energy through phase change (latent heat), are classified into organic and inorganic substances, and are commercially available, with a wide range of properties, such as phase change temperatures, latent heat values, etc. It is estimated that a PCM with a phase change temperature of 25 °C will be adopted, for nighttime solidification to occur in the climate of Cluj-Napoca. PCMs have less effective thermal insulation properties compared to air/argon and can cause overheating after daytime melting. Thus, within the PCM layer, a coil manufactured out of transparent tubes will be immersed. The extracted heat will be transferred to the domestic hot water (DHW) heating system, to preheat the DHW. Therefore, the final product will obtain Building Integrated PV thermal (BIPVT) system features, increasing buildings’ energy efficiency by reducing cooling load and boiler energy production, and increasing PV power generation, with the disadvantage of decreasing daylightin

Abstract:

Cities are the main focus of demographic, economic and territorial development in the European Union. However, urbanization has also revealed the existence of social and environmental problems implicit in this process. Urban gardens are a key component of the traditional urban and peri-urban landscapes of the main European cities. Beyond food production and consumption, urban gardens provide several ecosystem services in terms of social, cultural, territorial or environmental benefits. Thus, the main aim of this project is to promote the implementation of urban gardens and agroforestry experiences as key components of the strategic framework for sustainable urban development in Europe, from an interdisciplinary approach.

Abstract:

In the development phase of the energy audit documentation, a significant volume of calculations is generated when evaluating the thermal performance of the building envelope elements.The number of distinct elements of a standard building, e.g. types of exterior walls whose thermal performance is influenced by the position of the wall on the building height,by the geometric dimensions of the elements, by the existence of various types of door and windows openings, leads to an increased variety of thermal performances that should be assessed.For the energy auditing and expertise activity, several computer programs are available, programs that can determine the energy consumptions of buildings requiring as entry data the thermal performance of the building envelope elements.These thermal performances are given with varying degrees of accuracy, usually in the current field of the element without considering the linear thermal bridges.When the linear heat transfer coefficients ψ are used, the details existing in the thermal bridges atlases do not cover the real situations encountered in the current design, thus resorting to approximate details.There exist situations when the technical documentation of the building is not available, which leads to various assumptions regarding the detailing of the building envelope.In this regard, the project proposes the development of a methodology accompanied by software called THERMOG that evaluates the thermal performance of the building envelope under actual operating conditions using the aerial and terrestrial thermography method.The thermal performance assessment is carried out based on the geometrical and physical properties of the component materials upon making the expertise and not based on the normed values or the values declared by the manufacturer.The methodology developed in the project significantly reduces the duration of the auditing activity of a building and obtains results based on the actual behaviour of the build

Abstract:

Building sector is one of the biggest energy consumer being responsible for more than 45% of the total worldwide energy demand. Moreover, year by year the CO2 emissions around the world are higher and global warming threats are more and more visible. In this context, the use of renewable energy sources in order to achieve indoor comfort and low energy consumptions is mandatory. Transpired solar collectors are usually a cost-effective solution taking into account their low cost of investment, high efficiency and fast return of investment. Through the nanoSUN project we propose a new innovative transpired solar collector with integrated nano-enhanced phase changing materials (NEPCMs). This solution can improve the thermal conductivity of the storage material thus achieving our goal to obtain a solar collector with low outlet temperature variations and a large amount of operating hours during the periods when solar energy is not available. Our idea is to take advantage even of the concept of climate adaptive building shell proposing an improved concept where a NEPCM core will stay in fixed position in the façade and an advanced insulation - aerogel based module – will change position as a function of season and day/night period, allowing to a true optimal behaviour of the dynamic element of solar façade.

Abstract:

Întreaga omenire a fost perturbată de extinderea pandemiei de COVID 19 de la o țară la altă utilizând căile de comunicație ale lumii moderne. In timp ce statisticile indică aproximativ 220 milioane persoane infectate pe glob, IATA a înregistrat o scădere a veniturilor anuale globale din transportul de pasageri de aproximativ 126 miliarde euro precum și alte pierderi indirecte legate de aspectele economice și sociale grav afectate de virus.

Proiectul SAFE își propune o abordare cuprinzătoare în acest sens pentru a putea răspunde noilor cerințe în ceea ce privește asigurarea un microclimat îmbunătățit al pasagerilor la bordul aeronavelor comerciale în scopul reducerii semnificative a transmiterii aeriene a virușilor de tip SARS sau similari. Pentru a atinge acest obiectiv, ne propunem să investigăm o combinație de strategii diferite de ventilație personalizată de protecție (PPV) utilizând mijloace de protecție precum ecrane, hote sau cabine. Conceptul SAFE folosește avantajele dispozitivelor clasice de ventilare personală care asigură o curgere cu impuls redus pentru a crea în jurul capului pasagerului un curent de aer protector. Vom explora comportamentul și interacțiunea fluxurilor menționate mai sus cu panașul termic al corpului uman. De asemenea vom testa aceste fenomene și atunci când jetul provenit de la al doilea difuzor este umidificat și vom analiza efectul combinat obținut prin cuplarea sistemului de ventilare personalizată.

Abstract:

The goal of the XTREME project is to contribute to the challenge of the development of new components, systems and architectures required for the next generation of EVs allowing to meet end-users expectations in terms of cost, convenience of long range travel and comfort. Our project is proposing a breakthrough heating and cooling concept to minimize the impact on electrical vehicles range in extreme conditions through a complementary technology, such as localized conditioning of the human thermal environment.

The scope of XTREME project is to develop an experimental demonstrator in order to proof the functionality of the concept for a smart system allowing local heating or cooling of EVs passengers in the same time with the reduction of the electric energy consumption.

Cold weather presents two main challenges for EVs: cold air limits battery performance and running the heating system drains the battery. As temperatures go below freezing, some drivers accustomed to traveling 150 km on a single charge have seen their car’s range drop to 100 km. Drivers in extreme climates might see the range decrease even more. In the same time, during the summer, the air temperature in the vehicle and its interior surfaces could easily reach very high values resulting in a cooling load that is difficult to control only with the air conditioning system (i.e. only through convective heat transfer). The project’s concept is oriented towards the development of a smart heated/cooled car seat prototype for the next generation of EVs. This goal will be achieved by implementing the following objectives: O1. Development of new detailed thermal sensitivity maps of the back seat and gluteal regions with application to local and heating with contact elements, using a new approach based on a grid of sensors and IR thermography; O2. Design of optimal shape of thermal elements based on the previous new detailed high-resolution thermal sensitivity regions; O3. Choice of the best solutions of thermal elements in order to combine them in the new prototype. Several resistive and TE elements solutions will be tested; O4. Design of a control module based on pressure sensors and integration of a metabolic rate control law; O5. Smart heated/cooled seat integration along with its control module and final tests. The completion of all five previous objectives will allow the two general objectives to be achieved.

Abstract:

The building and food sectors are two major actors in the world energy consumption. Researchers are indicating that world food and energy consumption is set to mark a significant growth by 2050. The rapid urbanization that is taking place goes together with a rapid increase in urban poverty and urban food insecurity. The overall goal of BISCUIT project is to endorse the circular economy concept, helping local urban agriculture development for a sustainable food future. The project aims to prove that the renewable energy sources used for heating the buildings during the cold period can successfully also address the energy needs of urban farming, in the process of food preservation during the cropping period, closing the loop. Thus, the symbiotic system of the building, as a shelter and as a food source, integrates seamlessly in sustainable urban communities. The scope of BISCUIT is to develop an experimental demonstrator to prove the all year-round functionality and efficiency of the concept building adaptive solar energy system, integrating cascaded Phase Change Materials, for passive air heating and food drying purposes. The specific objectives of the project are : O1: Definition of the requirements and conceptual design of the demonstrator; O2: Thermo-dynamic optimization of the solar dryer; O3: Optimization of the adaptive solar façade; O4: Integration of the optimized dryer system and solar collector in a functional experimental set-up; O5: Creation of the building integrated system model. Thus, the adaptive solar system will lead to two main objectives: providing the pre-heated building fresh air during the cold period and providing heated air for drying process of the crop resulted from local urban farming during the warm period. This project proves a technical application of energy recovery of the wasted heat generated by energy usage during summertime, also contributing to the heat island effect.

Abstract:

In the construction domain, the energy represents the key-point in achieving efficient buildings.

The project proposes the improvement or institutional performances between three universities and two research institutes for the revival of the research activities and transfer of knowledge between partners.

The 4 proposed projects, centred on the efficient energy buildings, are focused on two principal research directions: (i) use of smart facades with low-thermal transfer, actively integrated for the enhancement of internal comfort and possessing a passive control of energy (by using the solar energy) and (ii) smart energy efficiency through building automatization and solar energy collectors. The resulted system, the smart house, is conceived thus to minimize the input energy for maintenance.

The Project 1 has as main objective the determination of mechanical properties of cellular materials used as thermal insulations in smart façade systems, through mechanical compression, bending and toughness fracture testing of such cellular materials.

Project 2 is focused on obtaining, characterizing and testing of high-property materials used for smart facades as thermal insulation materials and as support for special property layers: photo-catalytic layers and with reduced absorption/reflexion of UV-VIS-IR radiation.

The Project 3 has as main objective the theoretical and experimental investigation of the implementation of the electric power distribution in direct current for individual households or in small communities (smart-grid), with renewable energy sources integration.

The scope of the Project 4 is to implement the knowledge and data resulted from projects no. 1-3 through a modular laboratory demonstrative application. The project will perform an integrated study on the influence of the facades and the energetic contribution to the internal comfort of the building by considering different façade systems and respectively by integrating a smart-grid energy system.

Abstract:

In many industrial applications, heat and mass transfer is controlled by the use of impinging jets. These particular flows can produce very high heat/mass transfer rates since they exhibit amongst the highest known levels of transfer capabilities for single phase flows, especially at low nozzle-to-plate distances. The great implications that vortical structures can have on surface heat or mass transfer rate motivated the flourishing of countless investigations devoted to passive and active strategies of enhancement. Passive strategies are mainly based on the optimization of the shape of the nozzle. For instance, nozzles with chamfered outlets produce 20–30% increase of the heat transfer rate when compared to non-chamfered ones. Less studied from this point of view, but maybe the most promising passive devices, lobed nozzles are also examples of configurations that lead to enhanced heat transfer values. With respect to the circular impinging jet, a cross-shaped lobed jet attains the highest average heat transfer rate in the considered range of the Reynolds number compared with other devices in the literature, with very high heat transfer peaks. On the other hand, mixing and turbulence enhancement can be also promoted directly on the impinged surface with surface structure modification, an increase of the average Nusselt number value by 12–23% can be produced. Surface roughness, in the form of cubes, was found to produce heat transfer augmentation in the range of 8–28% while a dimpled surface is reported to reduce the heat transfer coefficient as compared to a smooth surface.

The general objective of the project is to propose an optimal combination of the two types of passive flow control methods in order to achieve higher heat and mass transfer rates for impinging jet flows. Applications of this fundamental problem are related generally for impinging flows to paper and fabric drying, furnace heating, food processing, electronic industry, etc.

Abstract:

Wastewater treatment plant Glina was built as a prerequisite for joining the European Union. Construction of a modern wastewater treatment in three steps was absolutely necessary, as required by EU, being put into operation by Apa Nova SA in 2011. On the sludge dewatering line in the Highly Dehydrated hall, the working environment for the process treatment is inadequate to exploitation for humans, due to a malfunctioning ventilation system. After processing the sludge it results different chemical compounds such as water vapor, hydrogen sulphide and ammonia, and calcium oxide powder or polymer. To avoid these problems, Apa Nova SA has to suspend the human activity, with long pauses to protect their employees. In the current conditions of operation and maintenance of this technological line there are high costs caused by increased maintenance time and hence the equipment unavailability time. To solve these problems, Apa Nova SA decided collaboration with UTCB in order to provide an optimal ventilation solution, obtained using the latest technologies available in the University. The research team can ensure concentration measurements, numerical studies conducting air flow (CFD) and experimental investigation by optical techniques (PIV and LDV) and also proposing solutions supported by the best technical skills of the team. The project aims defining an optimal solution for ventilation of the hall for highly dehydrated sludge and improvement of technological parameters and working conditions. This solution will adapt existing general ventilation system and will prepare for the introduction of local solutions to capture and treat effluent from the process line. The interdisciplinary quality of the research team recommends it as the only alternative approach absolutely necessary of such a study.

Abstract:

The scope of SMARTSENSE project is to develop an experimental demonstrator of smart system which automatically monitors the level of pollution in urban areas based on a real time monitoring network. This demonstrator will allow in a future development to propose a useful tool. On one hand the citizens will have an awareness tool allowing the effective public participation and contribution to subjective perceived air proquality. On the other hand, public stakeholders (city municipalities, traffic police, ministries of health e.g.) will have an effective tool for helping them in their short, mid and long term decisions regarding specific control actions. Some of such actions can be done automatically based on well-defined scenarios and available urban controls (e.g. automatic change of the average traffic speed, density, re-routing, commands to specific emitter to change the emission level temporarily due to particular wind rose or fog e.g.). The concept of the smart system proposes to constantly map the outdoor air pollution quality and to correlate the levels with the relevant international and European standards. When the risk of over passing is calculated, the smart system further calculates an associated risk with the traffic dynamics, obtaining risk predictions for certain areas of the city and certain hours. The project will have two general objectives: The project will have two general objectives: (i) developing hardware components of a platform dedicated to monitor the outdoor air quality of a representative neighborhood one hand and (i) developing mathematical models from the experimental data in order to provide predictions for uncovered spatial points and forecasts on the other hand. Both general objectives will allow the integration of a small scale experimental demonstrator of the proposed smart system. The validation of the demonstrator, both in laboratory and at a small neighborhood scale, will show the possibility of future extension.

Abstract:

The building sector remains an important player on the international economy dynamics, regulations demanding a high energy performance for significant reduction of the energy consumption. The purpose of project SCOPE is to prove the efficiency increase due to innovative lobed geometries of collector’s perforations and other pass-through elements disposals complementary with the inertial components implementation, underlining the benefit of passive solar systems. The project starts at TRL3 from the previous work which proves that the concept of solar collector with lobed perforations is functional and effective, but not yet integrated in a complete system. Project ends at TRL4 as a validated technology. There are 5 specific objectives: 1. Thermo-dynamic characterization of large-scale TSC models by CFD methods. 2. Experimental set-up for permanent regime conditions. 3. Experimental set-up for transient regime conditions. 4. TSC mathematical model coupled with solar radiation stability model. 5. Determination of the selection process constraints for the proposed TSC. During the SCOPE project the innovative ventilated solar facade will be studied experimentally to validate the technology and numerically for optimization and testing. The numerical models will serve for parametric studies of the proposed technology in order to find the optimal configurations. The solar façade element will be integrated in a functional ventilation system for fresh air heating. The analytical model will offer a powerful tool for simulation of the system in transient regime and the possibility of integration in dynamic energy simulation programs, including a technical selection data file, which will give important information on application domain.

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:

This project will develop an advanced system for active flutter and vibration control and gust alleviation for critical aerospace applications. Flutter is a critical phenomenon of unstable structural vibration occurring without warning when a critical flight speed is exceeded and may lead to flight accidents and loss of lives. Gust is a dynamic aeroelastic phenomenon resulting in excessive fatigue and vibration that shortens the aircraft life and may lead to unpredicted failures. Our proposed Antiflutter Demonstrator with Piezoelectric Actuation (AFDPA) system will prevent these critical phenomena by applying advanced control laws and algorithms based on the Maximal Lyapunov Exponent (MLE) methodology. The implementation of this active flutter and vibration control approach will be done through the use of high-bandwidth piezoelectric actuation embedded into a “smart wing” design that will be able to respond with great speed and precision to the MLE controller and thus prevent in flight accidents. The AFDPA team (INCAS, ROMAERO, UPB, COMOTI, STRAERO, UTCB, INAV) is uniquely positioned to perform this research because INCAS technical staff, in collaboration with experts from the other team members, has unmatched expertise and there is no other team in Romania and even South Eastern Europe that could perform this challenging project.

The idea of flutter vibration active control and gust alleviation is not historically new but the technological enablers for implementation have only recently become available through induced-strain actuated smart structures using piezoelectric active materials. The literature reports several concepts of smart-materials active vibration control of helicopter rotor blades, some of them even built and flight tested. However, there are almost no similar results for fixed wing aircraft; this is due to the more difficult challenges posed by the fixed-wing smart-structures aeroelastic applications, i.e., greater torsional wing stiffness, larger aerodynamic forces, and greater required deflections, difficult to overcome with conventional piezoelectric actuators. In this project, we are going to address this challenge by applying the theory of maximum energy extraction from induced-strain actuation in the presence of stroke amplification and kinematic linear-to-rotary conversion. We will aim at achieving efficient stroke conversion from linear to rotary with optimum energy transduction and maximum efficiency through an innovative kinematic analysis and design coupled with advanced modeling of the unsteady aerodynamic forces. In the proposed project, we will utilize the servo-tab concept that uses aerodynamic forces to obtain control surface deflections with fractional actuation force. However, the use of servo-tabs with unsteady aerodynamics requires very fast (high bandwidth) actuation and controller since otherwise the system may go unstable. Our proposed piezo actuation solutions will ensure the required bandwidth whereas the MLE controller will assure avoidance of unstable feedback situations. We will also develop a simpler smart flap solution where the piezoactuation is applied directly to the flap through an adequate linear-to-rotary stroke amplifier. Both solutions will be implemented into a smart wing wind tunnel model that will be extensively tested and analyzed. Essential for the project success are the MLE controller algorithms.

The outcome of the proposed project will be a methodology and experimental confirmation of a smart-wing solution for flutter vibration control and gust alleviation, that will enable aircraft to fly faster and more efficiently in turbulent atmosphere under adverse weather conditions. The effective collaboration of Romanian research institutions, academia, and industry will ensure a high technology readiness level (TRL) of the project results with high chances of industrial implementation and patentable innovation.

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:

HVAC systems have to provide clean air and to maintain comfortable conditions for the occupants. Usually applied total volume ventilation (TV) is inefficient because clean and cool air supplied has time to mix with the polluted warm air from the room before it is inhaled. TV is also energy consuming due to the principle of generating an uniform environment in the entire room, including areas which are not occupied. Personalized ventilation (PV) is a new development in the field of air distribution for buildings but is widely used in the automotive, train wagons, aircraft cabins. The main idea of PV is to provide clean air close to the face of each occupant and to improve thermal comfort in his microenvironment. Main objectives of the current project are: 1.Studying and developing innovative passive methods for generation of free isothermal and non-isothermal jets with different characteristics; 2.Studying and optimizing the interaction of the jets with the thermal flows generated by human body with focus on cooling effect and supply of personalized air to the breathing zone; 3.Development and integration in a real environment of two innovative prototypes, one with high mixing and one with reduced mixing; 4.Patenting innovative prototypes of air diffusers for PV. Project's objectives will be achieved both through parallel numerical simulation of the flow and by experimental measurements by optical diagnostics techniques.
