“…The comparison aims to benchmark the proposed solar water heating system with the typical serpentine configuration. In this case, this traditional serpentine solar heating system is utilised to meet the thermal demand of the same health centre based on single hot water tank with a volume equal to the total volume of hot water demand for the three applications as in generality of much-published work with a single centralised storage tank was used for this collective application (Lima et al, 2015;Fertahi et al, 2019;Li et al, 2020). Consequently, the monthly average daily system performance is evaluated based on the sets of equations described in section 2.4.…”

The standard flat-plate solar collector utilises a single copper tube to remove the absorber plate’s heat. This type of collector’s primary purpose is to provide hot water for a single application. Hot water can be required for different applications at different temperatures. Besides, using the standard collector’s configuration may increase thermal demand and increase the collector’s size. Therefore, this study proposes a novel solar water heating configuration that uses three in-line fluid passages. The goal is to design a single collector that provides hot water for various uses: Sterilisation, washing, and postnatal care. Thus, the proposed system was modelled, and a numerical simulation conducted. This analysis compares the proposed system’s output and the standard collector’s output. The results showed that the thermal load demand was reduced by 27% when the hot water demand for these services was generated using three separate tanks. The serpentine collector’s efficiency with three fluid passages is increased by 20% compared to the traditional serpentine collector. The thermal energy delivered to meet load was 30% higher than that of the traditional serpentine system. The experimental and simulated system performance is in near agreement with an average percentage error Cv(RMSE) of 8.75% and confidence level NSE of about 87%. Since the proposed serpentine collector has a higher overall thermal production, it is recommended for use with hot water, which has to be heated to different temperatures.

“…In order to realize the sustainable use of energy, household energy conservation, building energy conservation, energy conservation behavior, and other related aspects around household energy consumption also generated considerable research interest. For example, Fertahi et al [12] carried out various dynamic simulations on the thermal performance of the collective hot water production system, and found that the Evacuated Tube Technology (ETC) is suitable for this collective hot water production application, and increasing the centralized storage tank volume enhances the annual solar fraction of the collective hot water process. Pochwat et al [13] compared two-prototype near-horizontal drain water heat recovery units on the basis of effectiveness, and proposed a method to improve the utilization rate of hydrothermal energy.…”

With the emergence of the contradictions between energy supply and demand, considerable attention has been paid to the residential household energy consumption with increasing research in this field. Based on databases of Science Citation Index Expanded and Social Sciences Citation Index, this paper applies the bibliometric method to analyze the development and evolution of this research field using the literature published in the field of residential energy consumption during the period 1970–2018. The following findings were found: (1) The research on energy consumption of households is mainly divided into three stages: cognition (1970–1989), exploration (1990–2005), and rapid development (2006–2018); (2) By analyzing the citations of high-yield authors, institutions, journals and papers in this field, it is clear that the developed countries such as the United States, Britain, and the Netherlands have significantly stronger research capabilities in this field; (3) By analyzing the co-occurrence of keywords and co-citation of the literature in this field, the research hotspots in this field are summarized as the relationship between energy supply and demand, energy use efficiency, the relationship between various household indicators and energy consumption, environmental protection, modeling and measurement; (4) In view of the reality, future works should pay more attention to the influence of micro-factors, regional energy consumption issues, and energy consumption of rural households.
