Abstract

Because of easy availability and low cost, water is commonly used as a sensible heat-storage medium in solar energy applications. In this investigation two schemes of water thermal storage (active and passive) were designed and constructed from readily available materials. A dynamic computer model was developed to predict the thermal performance of the water thermal-storage systems under various charging and discharging conditions. Experimental tests were also conducted. The simulated results and measured data compared favourably, and these results showed that the water thermal-storage systems responded well to step and fluctuating input temperature changes. The water thermal storage may be satisfactorily used in varied solar energy applications where energy storage is necessary.

Performance evaluation and nanofluid using capability study of a solar parabolic trough collector
2015, Energy Conversion and Management
Citation Excerpt :
The prototype possessed a 75 m2 parabolic trough with a Miro aluminum reflector, a heat collection element with a selective coating and air-filled annulus between the absorber tube and glass envelope [7]. Thermal performance of trough collector was first evaluated by Arinze et al. [8] using water as the working fluid. A dynamic computer program was evolved by them for predicting the thermal performance of a water storage system under different charging and discharging conditions.
The aim of present work is to prepare a standard pilot of trough collector to investigate the ways of its performance enhancement. In this paper, a pilot of trough collector was designed and manufactured in a simple way with a 0.7 m width and 2 m in height reflector, which was made of steel mirror. The design, construction procedure and the new shape of receiver coupling are defined by details in the manuscript. The transient response and the optical and thermal performances of the collector were compared using four kinds of receivers: a black painted vacuumed steel tube, a copper bare tube with black chrome coating, a glass enveloped non-evacuated copper tube with black chrome coating, and a vacuumed copper tube with black chrome coating. Then 0.2% and 0.3% carbon nanotube/oil based nanofluids were prepared as working fluid and tested in the pilot with the black chrome coated vacuumed copper absorber tube. All the operating conditions were considered according to ASHRAE Standard 93 (2010) in all steps of test procedure. The results show that the global efficiency of vacuumed tube is averagely 11% higher than the bare tube efficiency, which is in good agreement with the previous works. Also, the nanofluid shows high thermal potential for further and more complete examinations. At last, a model of global efficiency is curve fitted for present prototype and compared with the previous models.
Performance investigation of a solar heating system with underground seasonal energy storage for greenhouse application
2014, Energy
Citation Excerpt :
However, in cold climate, the greenhouse structure is usually not sufficient to keep the inside air temperature at an appropriate level, so auxiliary heating systems are required concurrently. According to the different heating methods, these greenhouses are classified into active and passive ones [1,2]. In addition to the conventional gas boiler, several important existing heating systems with alternative energy sources, mostly solar energy, are documented by Refs. [3,4], including water storage, rock bed storage and phase change material storage.
This study reports the performance of a demonstrated 2304 m² solar-heated greenhouse equipped with a seasonal thermal energy storage system in Shanghai, east China. This energy storage system utilises 4970 m³ of underground soil to store the heat captured by a 500 m² solar collector in non-heating seasons through U-tube heat exchangers. During heating seasons, thermal energy is delivered by the heat exchange tubes placed on the plants shelves and the bare soil. The system can operate without a heat pump, which can save electricity consumption and further enhance the solar fraction. It was found that in the first operation year, 331.9 GJ was charged, and 208.9 GJ was later extracted for greenhouse space heating. No auxiliary heating equipment was installed so that solar energy covered all the heating loads directly or indirectly. It was demonstrated that this system was capable of maintaining an interior air temperature that was 13 °C higher than the ambient value when the latter temperature was −2 °C at night. The ECOP (electrical coefficient of performance) of the first operation year was approximately 8.7, indicating a better performance than the common heat pump heating system.
Performance studies of a solar parabolic trough collector with a thermal energy storage system
2012, Energy
Citation Excerpt :
The use of the PTC on a small scale model for hot water generation was performed in [13]. The investigation of thermal performance evaluation of sensible heat storage system using water as heat transfer fluid was conducted in [14]. A dynamic computer model was developed by the authors to predict the thermal performance of the water-storage systems under various charging and discharging conditions.
Concentrating collectors are used primarily for power generation applications, though recent applications include industrial process heating and institutional cooking. In the present work an experimental study is carried out to investigate the performance of a solar parabolic trough collector (PTC) integrated with a storage unit. The system consists of a PTC, a thermal energy storage (TES) tank containing 230 L of Therminol 55 which is also used as the heat transfer fluid (HTF) and a positive displacement pump. An increase in the temperature of the Therminol 55 in the storage tank is observed during the experimental trial conducted for a day, and the performance parameters like the collector's useful heat gain, thermal efficiencies of the individual/overall components of the system are evaluated and reported along with the operational experience gained. The scope for further increasing the efficiency of the system is also highlighted.
