“…New concepts in thermal storage applicable in community settings have been proposed and examined, such as systems that integrate solar collectors and storage units (Kumar and Rosen 2010;Terziotti et al 2012;Wang et al 2012). Many researchers review TES technologies suitable for building applications, with a focus on storage materials and their classifications, recent developments, limitations and possible improvements for building uses (Tatsidjodoung et al 2013;Cabeza et al 2011).…”

The status and needs relating to the optimal design of community seasonal energy storage are reported. Thermal energy storage research has often focused on technology development and integration into buildings, but little emphasis has been placed on the most advantageous use of thermal storage in community energy systems. Depending on the composition and characteristics of a community, the most appropriate community thermal storage may differ from that for a single building. District energy systems usually link thermal users to cold supplies and/or heat supplies (e.g., solar thermal energy, geothermal energy from ground-source heat pumps or geothermal hot zones, industrial waste heat, thermal energy from cogeneration or trigeneration). It is demonstrated that the optimal integration of these technologies can be enhanced through the use of appropriate seasonal thermal energy storage and that community-level seasonal storage can facilitate the development of smart net-zero energy buildings and yield efficiency, economic and environmental benefits. Issues that need to be resolved to allow optimal solutions to be attained are described. Advanced tools are required for modeling, simulation, analysis, improvement, design and optimization, which incorporate advanced methods like exergy analysis. The most appropriate scale, number and type (e.g., sensible, latent, thermochemical) of thermal storages in a community need to be better assessed, and the appropriate time duration capacities for each determined in an optimal manner. This is particularly important since a combination of short-, medium-and long-term storage is sometimes required to yield the most benefits from community energy systems.

Abstract. Solar energy is known as an environmentally friendly energy source with a wide range of applications. This energy can be utilized in various applications such as domestic and industrial water heating using solar water heating (SWH) systems. The thermal performance of an SWH system using a Vshaped absorber plate is presented in this study. Two SWH systems with different absorber plates, i.e. a flat-plate and a V-shaped plate, have been investigated experimentally. First, the absorptivity of the absorber plates was calculated analytically. The optimum V-shaped configuration with angle at β = 21° (V-shaped dimensions t = 4 cm and l = 4 cm) was determined from various V-shaped plate absorbers based on their absorptivity and applied in the experimental study. Two SWH systems were installed and tested at a low flowrate of 0.5 L/min and at a high flowrate of 2 L/min. The results showed that the SWH system with V-shaped plate absorber had a 3.6-4.4% better performance compared with that of the system with flat-plate absorber.

“…In active systems, there is a need of electric pump, valves and controllers to circulate the water, whereas the passive systems do not require external pumping for water circulation. Normally, direct systems are complicated, expensive, sensitive to freezing conditions and can only heat the water to moderate temperatures in the range of 50 to 60 o C [4]. Nevertheless, few design alterations are possible to overcome the freezing issues.…”

Abstract.A passive thermosyphon heating system was designed, fabricated and tested for its thermal performance in semi-arid and four-season climate of Pakistan. The heating system design was based on a two-stage storage and natural thermosyphon circulation of the water. The objective of the study was to enhance the heating performance of the thermosyphon systems by using a semicircular steel pot collector, water carrying copper coil cover, two step water storage, and side mirror reflectors. The experiments were conducted during April to July 2014 when ambient temperature was reported to vary between 32ºC and 44ºC. In continuous flow mode operation, the hot water temperature remained between 46ºC and 78ºC. Since water temperature in the range of 45ºC to 50ºC is considered suitable for the domestic use, the presented design can easily reach the temperatures even higher than those acceptable for the domestic use.
