Simulation of Thermal Processes in the Solar Collector Which Is Combined with External Fence of an Energy Efficient House

Due to the fact that the number of natural disasters in the world has increased in recent years, experts note that climate change is the cause. As a consequence of the nature of the needs to improve the fuel and energy complex in the countries in world. This solution could be solar energy and similar energy sources. The paper presents the classification of energy-efficient houses proposed by international standards and its critical analysis. Emphasis is placed on the problem of improving solar collectors integrated into the construction of buildings. The paper presents the temperature characteristics of an experimental solar collector. For the experimental solar collector combined with the translucent facade of the building, thermal characteristics are set, in particular, such as thermal capacity and thermal efficiency.

The background of this article is the potential energy savings of solar heat supply systems due to the use of the renewable energy of solar radiation. The motivation is to create a solar collector design that would combine the functions of both a building cover and a solar collector. It is necessary to investigate and compare different types of solar collector coatings (traditional and modern) and pipe diameters. The purpose of the article is to solve aspects of energy efficiency for new eco-friendly solar collectors. The most effective result occurred with the solar collector covered with the rubber–graphite composition of Grafplast PDA, and when using Prandelli/Tuborama pipes with a diameter of 0.016 m. Their efficiency increased by 8% compared to the second version of the collector made using a more traditional solution. The influence of the distance between the pipes and the flow rate of the heat carrier on the efficiency of the solar collectors was evaluated.

“…The above-mentioned studies highlight that the elderly population's thermal experience in urban environments differs from that of other age groups and is due to age-related factors, such as changes in heat preference, thermal sensation, thermal comfort, CTR, and metabolic rate, particularly in harsh regions where natural thermal resources are insufficient [24][25][26]. Various factors, such as climate zones, race, cultural backgrounds, and habits, also play a considerable role in the thermal perception of the elderly.…”

The harsh climate and the aging of urban populations have negatively impacted the quality of life of the elderly in severely cold regions. As a result, there is an urgent need to improve environment quality and accurately evaluate outdoor thermal comfort. However, existing studies have paid little attention to older adults living in severely cold climates. This paper aims to fill this gap by studying the elderly population in severely cold cities with high aging rates in China. By combining on-site testing, questionnaire surveys, CFD modeling, parametric computing, and statistical analysis, the study presents an adapted UTCI for elderly people, as well as multi-seasonal prediction models. The results (1) show that the neutral ranges of the UTCI are significantly affected by both climate zones and age groups. Older people are more tolerant to heat but more sensitive to cold. (2) The results also reveal the importance of factors such as air temperature, wind speed, solar radiation temperature, wind direction, relative humidity, and cloud cover in evaluating outdoor thermal comfort. (3) Multi-seasonal thermal comfort models based on neural networks were developed, and empirical studies verified that the model had the highest accuracy in the transitional season and the lowest accuracy in the winter season.
