Despite the widespread use of HVAC technologies in residential and commercial buildings, there is growing awareness of thermal comfort, leading to more studies on this issue. According to international publication indexes nearly 60% of publications belongs to the categories of construction building technology, energy fuels, and civil engineering. It should also be noted that 40% of world energy consumption pertains to construction sector. In this context, radiant cooling and heating systems come forward with their low exergy destruction rates pointing out the potential to be energy-efficient due to their higher and lower operation temperatures. Displacement ventilation, with its low heating and cooling capacity, has not gained widespread preference. However, the increasing consciousness of global warming and energy efficiency, along with the fear of airborne virus contamination, views stand-alone or hybrid applications of radiant heating/cooling and displacement ventilation as potential future solutions. This review study investigates the impact of radiant heating/cooling and ventilation types, mixing, and displacement on thermal comfort performance, focusing on factors affecting thermal comfort in trending radiant cooling and heating applications like radiant walls, ceilings, and floors. The study emphasizes the importance of considering occupant preferences, building characteristics, and energy efficiency when choosing the most suitable heating and cooling systems for different indoor environments. Stand-alone and hybrid applications of radiant heating/cooling and displacement systems can enhance thermal comfort performance, with the exception of specific cases requiring a high thermal load or ventilation rate.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"149 23","pages":"13551 - 13579"},"PeriodicalIF":3.0,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the application of Al₂O₃ nanoparticles mixed with water as a base fluid to analyze the effect of intercooling in a two-stage reciprocating air compressor. The study employs a shell and tube heat exchanger with parallel and counter flow conditions. The computational analysis, facilitated by computational fluid dynamic software compares the thermal conductivity and heat transfer rates of water and Alumina Oxide based nanofluid to an air-intercooled system. Additionally, the study evaluates the isothermal and volumetric efficiency of the compressor, along with the work requirements for its low-pressure and high-pressure cylinders without using a chiller or external medium. While, achieving ideal intercooling conditions remains elusive in practical experiments, ongoing research focuses on enhancing intercooler efficiency through various nanofluid techniques.

However, most sensitivity analyses for these collectors are conducted under steady-state conditions. Because of the inherently dynamic nature of ambient conditions, dynamic modeling and sensitivity analysis are needed to better understand and determinate important influencing design parameters. This study presents a comprehensive parametric analysis using a dynamic model of the solar flat-plate collector. The impact of deviations from nominal values of each parameter on system performance and final storage tank temperature is investigated. The findings reveal that pitch tube and absorber thickness significantly influence system efficiency, with a 20% deviation in each parameter resulting in a 10% efficiency change. Moreover, ambient temperature and irradiance have a high impact, causing changes of over 10%. Additionally, a multiparameter sensitivity analysis utilizing the Monte-Carlo method (MPSA) is employed to assess the relative importance of each parameter on FPSC performance. The results highlight that system efficiency is highly sensitive to absorber thickness, while tube pitch, ambient temperature and solar irradiance are crucial for tank temperature. The MPSA is further applied across various ambient temperatures (ranging from 5 to 35 degrees) to determine changes in parameter sensitivity indices. The outcomes indicate that at lower ambient temperatures, certain parameters, such as solar irradiance and tube pitch, exhibit increased sensitivity. However, the sensitivity of system efficiency to all parameters remains relatively constant across different ambient temperatures.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"149 23","pages":"14313 - 14324"},"PeriodicalIF":3.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142758034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combustibility of the cigar wrapper, binder and filler was evaluated by the mass loss rate obtained from thermogravimetric experiments and the heat release rate obtained from the microscale combustion calorimeter experiments. The pyrolysis products were analyzed by infrared spectroscopy and mass spectrometry. The research results show that the similarities between wrapper, binder and filler lie in the elemental composition, combustibility and the main components of pyrolysis products. The difference lies in the fact that the surface microstructure of the wrapper is the smoothest, while the filler is the roughest with the leaf vein. The concentration of pyrolysis products in filler is significantly higher than in wrapper and binder after 400 °C.

Efficient thermal management is crucial to maintain temperature within safe operating limits. Using nanofluids in mini-channel heat sinks and optically tuned nanofluids in agricultural greenhouses has emerged as a viable solution for active cooling. This study investigates the thermal cycling performance of PCM-based heat sinks with and without pin fins to assess their suitability for long-term thermal management applications. Thermal cycling tests are conducted on PCM-based heat sinks containing RT-42 PCM and different pin fin configurations made from aluminum 2024-T851. The tests evaluated stability under a constant 10 W heat flux during both charging and discharging phases for baseline cases without fins. The results indicate that the maximum temperature difference between the 30th and 40th thermal cycles was only 0.97 °C, representing a mere 2.08% variation. This observation highlights the ability of PCM-based heat sinks to maintain a consistent temperature profile even under repeated thermal loading conditions. The PCM-based triangular pin fin heat sink was more effective than the circular and square pin fin heat sinks. It maintained the lowest average temperature at 32.83 °C and had the lowest rate of temperature increase during charging, at 0.463 °C per minute. Furthermore, the combination of PCM and triangular fins demonstrated superior thermal stability compared to other configurations. The maximum temperature difference between the first and 40th thermal cycles for this configuration is observed at only 0.83 °C with 1.38% variation. This exceptionally low-temperature difference underscores the effectiveness of the triangular pin fin design in promoting heat dissipation and maintaining thermal stability. The results highlight the potential of PCMs to enhance the long-term performance of electronic devices by maintaining optimal operating temperatures.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"149 22","pages":"12895 - 12915"},"PeriodicalIF":3.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142736896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
