“…Residential energy consumption includes space heating, cooling, water heating, and other thermal applications, such as cooking. Space heating and cooling are essential for the thermal comfort of residents as the productivity and satisfaction of the building's occupants are highly dependent on thermal comfort [173]. The share of energy consumption for space heating and cooling depending on the climate varies from country to country.…”

Supply disruptions, uncertainty, and unprecedented price rises of fossil fuels due to the recent pandemic and war have highlighted the importance of using renewable sources to meet energy demands. Solar air collectors (SACs) are major types of solar energy systems that can be utilized for space and water heating, drying, and thermal energy storage. Although there is sufficient documentation on the thermal analyses of SACs, no comprehensive reviews of the exergetic performance or qualitative insight on heat conversion are available. The primary objective of this article is to provide a comprehensive review on the optimum conditions at which the thermal performance of diverse types of solar air collectors is optimized. The effect of operating parameters such as temperature rise, flow rate, geometric parameters, solar radiation, and the Reynolds number on the thermal performance of SACs in terms of thermal hydraulic performance, energy, and exergy efficiencies has been reviewed adaptively. Beyond the operating parameters, a deep investigation is outlined to monitor fluid dynamics using analytical and computational fluid dynamics (CFDs) methodologies in the technology of SACs. In the third phase, thermodynamic irreversibility due to optical losses, thermal losses between absorber and environment, heat losses due to insulation, edge losses, and entropy generation are reported and discussed, which serve as the fundamental tools for optimization purposes.

“…Both productivity and satisfaction of building occupants are affected by thermal comfort inside the building (Ismail et al 2010). A number of environmental parameters including air temperature and humidity and personal factors like physical activity and clothing are considered for defining thermal comfort of occupants (Djongyang et al 2010;Wafi et al 2011).…”

Space heating appliances require significant amount of primary as well as secondary energy. In most of the countries, energy requirements for such utilities are met by burning fossil fuel or from conventional electricity. Such usual practices for space heating result in significant increase in greenhouse gas emission and fossil fuel depletion. In the line of global emphasis on energy conservation and switch-to-clean energy approach, solar thermal energy can be harnessed using solar air heater for space heating purpose. This paper studies the potential of using solar air heater in space heating applications. Associated critical issues like demand-supply mismatch, installation space constraint, annual utilization factor and undesirable variations in output temperature are highlighted. Further, current research trends toward improving applicability of solar air heater are also briefly discussed.

“…The course of work and labor productivity will be affected when employee had uncomfortable environment. Nevertheless, it is very difficult to satisfy the comfort of a group of workers in a factory, but realistically we can achieve a thermal environment that satisfies the majority of these workers, or more simply stated, 'reasonable comfort' [4]. Study by using a theoretical model of comfort [2], then make change to the model and solve the equation using Fathran software, chart of comfort with different comfort line developed for buildings in subtropical regions in China [5].…”

The successful of manufacturing factories in industry is highly dependent on a productivity of their employees especially operators. It was identified that comfort and noise level can reduce the productivity of their workers. This study is to determine the level of thermal and noise comfort in the battery plate factory. This study was conducted in three days and location of the study is at battery plate factory in Semenyih, Selangor, Malaysia. The scope of study is focused at plate manufacturing area where the employee estimated 40 persons. The thermal comfort level can be determined by calculating PMV and PPD. This study involved six factors of comfort which is air temperature, average radiant temperature, air velocity, relative humidity, metabolic rate and clothes insulation. Then the study of noise level was conducted by determining LAeq, T, Lmax and Lmin. To carry out this study, Babuc-A equipment were used. The analysis show the area of the manufacturing battery plate having a discomfort condition and PMV result is between 1.5 until 3. Air temperature on the other hand is between 27.4°C-37.8°C while relative humidity is between range 35.35% -92.1% and air velocity 0 m/s-1.28 m/s. Meanwhile the LAeq,T value in the factory is varied from 68 to 80 dB.
