Texto completo da fonteThe demand of energy consumed by human kind has been growing significantly over the past 30 years. Therefore, various actions are taken for the development of renewable energy and in particular solar energy. Many technological solutions have then been proposed, such as solar PV/T collectors whose objective is to improve the PV panels performance by recovering the heat lost with a heat removal fluid. The research for the improvement of the thermal and electrical productivities of these components has led to the gradual integration of the solar components into building in order to improve their absorbing area. Among technologies capable to produce electricity locally without con-tributing to greenhouse gas (GHG) releases is building integrated PV systems (BIPV). However, when exposed to intense solar radiation, the temperature of PV modules increases significantly, leading to a reduction in efficiency so that only about 14% of the incident radiation is converted into electrical energy. The high temperature also decreases the life of the modules, thereby making passive cooling of the PV components through natural convection a desirable and cost-effective means of overcoming both difficulties. A numerical model of heat transfer and fluid flow characteristics of natural convection of air is therefore undertaken so as to provide reliable information for the design of BIPV. A simplified numerical model is used to model the PVT collector so as to gain an understanding of the complex processes involved in cooling of integrated photovoltaic arrays in double-skin building surfaces. This work addresses the numerical simulation of a semi-transparent, ventilated PV façade designed for cooling in summer (by natural convection) and for heat recovery in winter (by mechanical ventilation). For both configurations, air in the cavity between the two building skins (photovoltaic façade and the primary building wall) is heated by transmission through transparent glazed sections, and by convective and radiative exchange. The system is simulated with the aid of a reduced-order multi-physics model adapted to a full scale arrangement operating under real conditions and developed for the TRNSYS software environment. Validation of the model and the subsequent simulation of a building-coupled system are then presented, which were undertaken using experimental data from the RESSOURCES project (ANR-PREBAT 2007). This step led, in the third chapter to the calculation of the heating and cooling needs of a simulated building and the investigation of impact of climatic variations on the system performance. The results have permitted finally to perform the exergy and exergoeconomic analysis

Texto completo da fonteRapid population growth and industrialization have led to a significant rise in energy demand globally, though a 1% drop occurred in 2020 due to the COVID-19 pandemic. Despite advancements in renewables, fossil fuels remain predominant. The building sector, ranking third in energy consumption, contributes heavily to CO2 emissions, with HVAC systems alone accounting for 50-60% of energy usage. Integrating photovoltaic (PV) technology into buildings via BIPV or BAPV offers a promising solution to reduce energy demand and CO2 emissions. However, the efficiency of PV cells is limited by heat generation, requiring passive cooling methods like natural convection, especially in BIPV systems, to maintain performance and longevity. Solar-assisted passive technologies like double-skin façades, Trombe walls, and solar chimneys utilize solar energy to enhance air ventilation in buildings. Among these, wall-mounted solar chimneys offer effective cooling and ventilation. Building upon NAMICO project, a unique indoor wall-mounted solar chimney with scaled-down room model have been fabricated at LOCIE for gathering reliable data on BIPV systems integrated on double-skin façade connected via horizontal inlet opening with the dwelling space.This doctoral research assesses a modular test bench in a lab setting, establishing protocols and criteria for experiments. The research explored the impact of window position and size on the performance of the solar chimney and room ventilation system. Experiments also investigate the effects of varying surface emissivity, set at either 0.08 or 0.96, and uniform heat flux injected solely from the inlet-forming wall of the L-shaped channel, at rates of 110 W/m² or 235 W/m². The top window of the room remains open while maintaining constant aspect and extension ratios of the channel. Thermal and kinematic performance of the L-shaped channel is assessed by analysing wall temperature data and conducting PIV measurements on whole channel once the solar chimney test rig reached quasi-steady state. The 2D time-averaged flow field within the channel was measured, and spatial flow structures were visualized. Additionally, the impact of room window placement and aperture size on ventilation was evaluated by measuring room air temperature and observing airflow patterns using a smoke generator. A simplified one-dimensional model, the Steady Heat Balance Model (SHBM), is also developed to predict the thermal and ventilation performance, validated using experimental data.it has been concluded chimney inlet geometry affects thermal field and flow topology in the vertical channel. Increasing heat flux boosts thermal field on walls and flow field within the chimney on both low and high emissive walls of the channel. Higher surface emissivity enhances wall-to-wall radiative heat transfer, altering wall thermal profiles and airflow patterns by modifying the thermal conditions from one-wall heating to asymmetrical of the channel. Consequently, the temperature of the heated wall decreases notably while the temperature of the opposing wall, receiving radiation, increases proportionally. Additionally, the volume airflow rate out of the chimney is computed to be higher at ε = 0.96 chimney walls compared to ε = 0.08 under the same heat flux. No reverse is observed at the outlet of the chimney even at low emissive walls of the channel. Sharp corners of the inlet create recirculation zones, the size of these structures are being affected by input heat flux and wall emissivity. It is also investigated that the size and placement of the window on room wall have no visible impact on chimney performance but influences room temperature distribution. Lastly, the modelling approach developed aids in predicting ventilation but overestimates chimney wall temperatures

The sustainability issues of recent studies are mainly focused on the energy preservation, environment protection, and economical development etc. One of the most beneficial senses is to utilize the natural driven forces to emphasize the air-exchange through the openings of the enclosure, and to reduce the dependence on utilizing the mechanical ventilation. This study, therefore, intends to develop the quantitative assess method as a tool during the design period to predict the naturally ventilated performances of rooms. Based on the literature review, numerical simulation was performed using CFD (Computational Fluid Dynamics) techniques. A full-scale bedroom Chamber was used in the experiments. Two types of windows were studied on the performances of different window positions and rotational angles. Our major findings were as below: 1. Close congruence with the experimental results shows the validity of numerical models. Those show CFD turbulence models in this study can act reasonably the role to predict the nature ventilation of buildings. 2. In the airflow of the forced convection, the standard k- model and the low-Reynolds number k- model are suitable, it, however, saves more calculated time using the standard k- model. In the airflow of the free convection, low-Reynolds number k- model performs more accurate, but a fine grid distribution near the wall boundary was necessary, and it took more calculated time. 3. In the seasons benefit the natural ventilation (spring & autumn), it is recommended utilizing cross-ventilation induced from the wind-pressure difference across the bedroom. For the bedroom-unit cases, wind-induced airflow was suitable for all of the window positions at the inlet wind-speed below 1 m/s. It was to avoid the window positions caused the mainstream through the head zone at the speed about 3 m/s. And, it was caused violently uncomfortable flow across the head zone as the air-draft effect for all of the window positions at the speed above 5 m/s. 4. In the seasons unfavorable for natural ventilation, especially in winter, it is used to close the door to keep warm in the sleeping nighttime. The single-sided ventilation, however, was harmful to provide convection. One of the solution is to utilize the central horizontal pivot window to introduce airflow into bedroom. For the bedroom-unit cases, when the window angle at 0-90°(cosθ>0), the airflow path induced from wind was against from stack, the ventilation efficiency at outdoor wind-speed UE = 0 m/s was more obvious than which at the slight wind-speed (UE = 0.3-0.5 m/s), the wind force, furthermore, become the major influence at wind-speed above 0.5 m/s. When the angle at 90-180°(cosθ<0), the airflow path induced from wind was overlapped from stack, the ventilation efficiency was greater accompanied the greater wind-speed.
