An important element of a solar installation is the storage tank. When properly selected and operated, it can bring numerous benefits. The presented research relates to a project that is implemented at the Solar Energy Research Center of the University of Almeria in Spain. In order to improve the operation of the solar cooling and heating system of the Center, it was upgraded with two newly designed storage tanks filled with phase change materials (PCM). As a result of design works, commercial material S10 was selected for the accumulation of cold, and S46 for the accumulation of heat, in an amount of 85% and 15%, respectively. The article presents in detail the process of selecting the PCM material, designing the installation, experimental research, and exergy analysis. Individual tasks were carried out by research groups cooperating under the PCMSOL EUROPEAN PROJECT. Results of tests conducted on the constructed installation indicate that daily energy saving when using a solar chiller with PCM tanks amounts to 40% during the cooling season.

Solar Water Heating System

The total area of solar collectors installed in Taiwan had exceeded 2 million square meters by the end of 2010. However, there were only 98 systems in operation with area of solar collectors installed exceeding 100 square meters from 2001 to 2010. To increase industrial awareness of solar water heating technologies, a nursery greenhouse was chosen as the case study to evaluate its thermal performance throughout the months of May 2010 to April 2011. The results showed that the solar energy collected and heat loss during the night hours would affect the thermal efficiency, economic viability and attractiveness of a SWH. This study would provide useful information for all parties related to this market, manufacturers, potential users and policy-makers.
