    Abstract Molten nitrate salts are widely used as heat transfer and energy storage medium in Concentrated Solar Power (CSP) systems. Solar Salt (60 wt% NaNO3-40 wt% KNO3) is the commercial binary molten nitrate salt, which is the preferred energy storage material with high density, high specific heat, low melting point, high thermal stability, and low vapor pressure. This paper explored the effects of impurity Cl− on the thermophysical properties of Solar Salt, including liquidus temperature, density, viscosity, and thermal stability. The results showed that Cl− can significantly reduce the liquidus temperature, and when Cl− was less than 0.5 wt%, the liquidus temperature of molten salt system decreased within 1 °C. On the other hand, Cl− had little effect on the density, viscosity and thermal stability of the mixed molten salt system at 400 °C, but at high temperature Cl− will promote the volatilization of components. By analyzing the thermostatic stability at 565 °C, it was found that the total mass loss changes less than 0.3% when Cl− was less than 0.01 wt%. After comprehensive analysis, the conclusion is that the upper limit of Cl− is preferably less than 0.1 wt% for keeping good thermal performances of Solar Salt.

    Abstract Molten salts have high solidification temperatures, so they easily solidify in the receiver tube when the incident energy fluxes are very low due to clouds drifting and floating across the sky. Additional energy and time are then wasted to thaw the frozen solid with the salt freeze/thaw cycles eventually damaging the receiver. Therefore, operators need to adopt appropriate operating strategies to ensure that the salt remains molten during extended cloudy periods. The present study presents a thermo-hydraulic dynamic model of a molten salt receiver to investigate the heat transfer processes. The model is based on the Badaling 1 MWth receiver experiment with three experimental groups of tests modeled to validate the thermal hydraulic model in both the direct-filling mode and the S-type flow mode. The model results agree well with the experimental measurements with maximum relative errors of 0.4% for the outlet temperature and 0.9% for the surface temperatures. Then, a sensitivity analysis is conducted to better illustrate the flow distribution and surface temperatures, including the effects of the flow resistance, inlet temperature, cloudy duration, and valve abnormalities. Finally, the results indicate that the S-type flow mode should be used to prevent solidification for cloudy conditions.

    Abstract Our purpose in the future will be the forecast of the global radiation for region of Hungary and certain stations. As a first step in this study we try to determine the average daily values of the relative global radiation from values of cloud coverage using satellite pictures and from other meteorological parameter (visibility). First the relative global radiation was considered as a parabolic function of the cloud coverage. A close relationship was obtained between the amount of cloud measured in tenth and the daily average value of the relative global radiation. To correct this formula the visibility was used for calculation of the relative global radiation above the cloud amount. The value of the multiple correlation coefficient was 0.96 for Budapest, and 0.91 for region of Hungary. This fact indicates a sufficiently correct formula for calculation of the global radiation.

    Abstract In this study, a typical rice paddy in Guilan province of Iran is considered and the technical and economical feasibility of the solar powered pumping system is studied. The monthly mean daily solar irradiance has been studied for this area and the measured data is compared with European Photovoltaic Geographic Information System (EU PVGIS) model for Middle East, including Iran. The investigations imply that the average monthly mean daily solar irradiance in irrigation months are reported equal to 5.92 kW h/m2/day by Guilan Meteorological Administration and 5.95 kW h/m2/day by EU PVGIS. A mean monthly clearness index from 0.54 to 0.57, in irrigation period, gives Guilan province a good potential to employ photovoltaic (PV) pumping system. In this study, the appropriate size of the PV panels and the lifecycle cost estimation of PV pumping system in comparison with conventional systems are presented. Also, the area of the PV solar panel to supply required power of the pumping system for a rice paddy with specified area is calculated. Results show that though the initial outlay of the PV system is about 9 times of the conventional systems but the total lifecycle costs of the PV pumping system is just 65.6% costs of the conventional pumping system. Also in spite of high initial costs of the PV pumping system, it is found that after around 9 years, the total costs of both systems would be equal to conventional one i.e. gasoline pumping system and after this time, the costs of the conventional pumping system will exceed the PV solar panel system.

    Abstract A thermal energy storage system (TES) is a key technology to ensure continuous power supply from solar thermal power plants. Choosing the appropriate storage method and the suitable material for energy storage remains a major challenge in research and development in the solar power field. The sensible heat storage in solid media using thermocline system is a significant cost-effective option when compared to liquid storage material in two tank system. An incorporation of this potential concept is the oil/rock thermocline system which is based on the direct contact between natural rocks chosen as filler material and thermal oil as the heat transfer fluid (HTF), and it is used in the Concentrated Solar Power (CSP) plants. The present paper highlights the thermal energy storage potential of six rocks (quartzite, basalt, granite, hornfels, cipolin and marble) proposed as filler material for thermal oil thermocline storage concept. These rocks were chosen according to their abundance in Morocco. Different technical methods were performed in order to assess the rocks properties (physical, chemical and thermal) at temperatures up to 350 °C (temperature operating conditions using linear Fresnel reflectors or parabolic trough). The thermal performances of the studied rocks inside a thermocline storage system were evaluated using a validated numerical model. Based on the experimental investigation two rocks (Quartzite and Cipolin) were identified as the most suitable filler materials to be used in direct contact with the studied HTF (synthetic oil). While, the numerical analysis revealed that Basalt rock has the best thermal performances inside the studied thermocline storage system concept, but it isn’t chemically compatible with synthetic oil. Hence, it can be used advantageously with other heat transfer medium (e.g. Air).

    Abstract Currently, the excess light above a light saturation point cannot be harnessed for plant growth in conventional greenhouse covers. In this study, we developed a solid compound parabolic concentrator (CPC) cover for use in greenhouses to convert excess light into heat. Optical simulation software was used to track the sunlight at different incident angles over time. We also conducted experiments to determine the transmittance and heating power of the solid CPC coating under real weather conditions. The maximum instantaneous thermal efficiency and thermal energy of a single solid CPC cover plate were 32.2% and 353 W/m2, respectively. The simulation results were in good agreement with the experimental output power and the trend of the actual transmittance of the covering material. The transmittance of the covering material was low when the midday sun was intense, and the transmittance was relatively high in the morning and afternoon. The variation of red and blue light in the greenhouse with the spectrum was analyzed at the same time. Studies have shown that this new greenhouse covering material can better adjust the brightness, make the illumination in the greenhouse more uniform, and thus improve the thermal environment in the greenhouse. The heat pipes converted excess light into heat, thereby achieving comprehensive utilization of solar light and heat.

    Abstract This paper presents an experimental study of a new designed Trombe wall, which is a part of the southern wall of a test room, in terms of energy performance and heating comfort during winter operation for Yazd city (Iran) desert climate. The area of the Trombe wall is 50% of that of the southern wall of the test room. Hence, it occupies less space and reduces the implementation costs. Contrary to the traditional Trombe walls in which the absorber receives solar radiation from one direction, this innovative design enables the absorber to receive solar radiation from three directions (East, South and West), therefore, the absorbing surface of the wall is subject to the solar irradiation during the all day time (from sunrise to sunset). The experimental results revealed that the range of room temperature on the coldest winter days and weeks in Yazd is kept within 15–30 °C, and this implies that the present Trombe wall design is able to provide a comfortable indoor temperature with lower difference between the maximum and minimum temperatures due to the increased stored energy of the Trombe wall. Furthermore, the present innovative design of the Trombe wall channel causes the absorber temperature to reach around 47 °C on the coldest winter days, indicating the highest possible solar intensity received by the absorber. Analysis of the hourly stored energy of the Trombe wall reveals that the more solar intensity leads to the more energy absorption and the higher Trombe wall back surface temperature, which in turn causes the hourly stored energy to reach to a maximum of 5800 kJ/h in February.

    Abstract Site adaptation refers to procedures for correcting systematic errors in an extended period of gridded modeled data using a short period of ground-based measurements used as unbiased reference. Traditionally, site adaptation leverages a single gridded product and issues point predictions. Currently, remote-sensed and reanalysis data are available from different sources providing multiple versions of estimates of a same atmospheric variable, for any location on Earth. These datasets allow what is called an ensemble prediction. In this regard, this contribution proposes a probabilistic site-adaption framework, and describes how one can use parametric and nonparametric techniques within the framework. On top of the stand-alone probabilistic site-adaption methods, heuristics are optionally used to combine quantiles, to further improve the accuracy of site adaptation. To exemplify the framework, global horizontal irradiance data from 26 sites worldwide with different climate characteristics and weather regimes are used to side-adapt the corresponding predictions from up to 5 satellite-derived databases and 2 reanalyses spanning various periods, collectively. It is found that the proposed site-adaptation methods using multiple gridded products are able to attain, on average, a 5 W/m 2 reduction in continuous ranked probability score than that leveraging just a single product.

    Abstract The random installation of various solar energy equipment on building roofs has caused visual damage to the cityscape. Keeping the rooftop equipment out of sight of the pedestrians is a new solution to eliminate visual pollution. Based on the complex urban street canyons, this paper describes a physical and mathematical model relating to the limiting height of equipment installations at any position on the roof. It is found that the limiting height of equipment varies with the building roof height, the street width, and other factors. In addition, for a case with four main urban roads, the variation patterns for the limiting height of rooftop equipment changed with the street width and the distance from the installation to the parapet have been established, which is of great relevance for determination of the limiting equipment height in actual installations. The research can not only help to remove visual pollution from rooftop equipment in street canyons, and provide a guide for the selection and installation of solar equipment, but can also provide significant information for urban space planning and building design.

    Abstract Accurate prediction of building energy performance requires precise information of the local climate. Typical weather year files like test reference year (TRY) and typical meteorological year (TMY) are commonly used in building simulation. They are also essential for numerical analysis of the sustainable and renewable energy systems. The weather year file of one city is often employed by the nearby cities for such purposes. In this paper, the developments of customized weather year formulation are reviewed. The key issues are discussed making reference to two neighboring cities, Hong Kong and Macau, using their weather data records over a century, and the typical weather year files developed. The findings support the preference of TMY over TRY. It is also suggested that the TMY selection process should include the most recent meteorological observations, and should be periodically reviewed to well reflect the long-term climate change.
