{"title":"Enhancement of Building Thermal Performance: A Comparative Analysis of Integrated Solar Chimney and Geothermal Systems","authors":"S. Agarwal, Rafael Cavicchioli Batista","doi":"10.56578/jse020205","DOIUrl":"https://doi.org/10.56578/jse020205","url":null,"abstract":": A comparative investigation is conducted, employing Computational Fluid Dynamics (CFD) simulations to study two distinct room space configurations: one featuring a solar chimney and another integrating both a solar chimney and a geothermal system. The primary objective of this investigation is to scrutinize the thermal behavior, energy efficiency, and mass flow rates of these systems. Results underscore the considerable positive implications of the geothermal system integration. This amalgamation precipitates diminished average room temperatures and elevated mass flow rates, signifying superior thermal comfort and energy performance. The room implementing the geothermal system exhibited an average temperature of 302.2 Kelvin and a mass flow rate of 4 . 134 × 10 − 6 kg / s , in contrast to the room without the geothermal system, which demonstrated an average temperature of 309.6 Kelvin and a mass flow rate of 1 . 878 × 10 − 6 kg / s . These findings have practical repercussions for architects, engineers, and policymakers, facilitating well-grounded decisions in the domain of sustainable building design. The observed enhancement in thermal performance and mass flow rates underscore the potential merits of integrating geothermal systems, thereby promoting wider acceptance. Further research is recommended to investigate the influence of varied climatic conditions, building orientations, and room layouts on the efficiency of integrated solar chimney and geothermal designs. Examination of alternative renewable energy sources (RES), innovative building materials, and technologies is also suggested to elevate energy efficiency and sustainability in room space designs. This study contributes substantially to the expanding realm of sustainable building design, providing valuable insights for refining room space performance, curbing energy consumption, and heightening thermal comfort. By highlighting the advantages of renewable energy integration, particularly geothermal systems, the study stimulates the development of more energy-efficient and environmentally friendly building spaces.","PeriodicalId":191087,"journal":{"name":"Journal of Sustainability for Energy","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115464153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results provide valuable insights for refining application-specific design guidelines and enhancing the performance of PFHEs. Using Computational Fluid Dynamics (CFD), the PFHE geometry was created in SolidWorks and Ansys Fluent, with fins modeled in three layers inside the heat exchanger both with and without a cover. To investigate the fins’ performance, flow field, and heat transfer, fin thickness, entry velocities, and locations of water and air were varied across three wavelengths (10, 20, and 30) during the numerical investigation. The analysis focused on the variations in pressure, temperature, and fluid velocity within the heat exchanger. Key findings include the observation that temperature distribution is influenced by the velocities of both water and air, with the upper layer experiencing a temperature increase due to the warm fluid stream, while the opposite effect is observed near the bottom layer. Furthermore, fluid temperature variation in the depth direction is attributed to conductive heat transfer through side plates and convective heat transfer to the surroundings. The outcomes of this study have the potential to reduce the pressure difference generated during heat exchange and increase the thermal efficiency of PFHEs.","PeriodicalId":191087,"journal":{"name":"Journal of Sustainability for Energy","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124628710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A field of vacuum tube solar collectors is sized to work in replacement of the heat recovery system of the water chiller. An economic and environmental analysis of the proposal is made. With the installation of the solar collectors, the hotel will deduct 27,545 liters (15,425 kg) of liquid gas propane (LPG) from its annual consumption, equivalent to 51,728 USD, avoiding the emission of 104,583 kg of CO2eq into the environment. The simple recovery time of the investment will be 5.88 years. The results obtained demonstrate the feasibility of using solar thermal energy in the heating of sanitary water due to the decrease in the consumption of liquefied petroleum gas and, therefore, the environmental damage is reduced when greenhouse gases are no longer emitted.","PeriodicalId":191087,"journal":{"name":"Journal of Sustainability for Energy","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133215459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
