✦ Synopsis
07 Alternative energy sources (solar energy) important role ar low altitude for thermal heating of either a building or a greenhouse during winter months. It mainly depends on the shape and size of greenhouse and time of the nth day of the year. Based on the analycis it can he concluded that the modified arch shape greenhouse is suitable for thermal cooling through out the year. Uneven \pan shape greenhouse is most suitable for thermal cooling ot living space in winter and heating in summer. in comparison to other chapes.
03/02413 Flow distribution in solar collectors with laminar flow conditions Weitbrecht, V. of cl/. Solar ,%PI. ~Y, 2002, 73, (6). 433-441. This paper presents the results of an experimental study conducted in a water solar flat plate collector with laminar flow conditions to analyse the flow distribution through the collector. LDA-measurements were carried out to determine the discharge in each riser, as well as pressure measurements to investigate the relation between junction losses and the local Reynolds number. Analytical calculations based on the measured relations are used in a sensitivity analysis to explain the various possible flow distributions in solar collectors. In addition, a simple parametric approach to predict the flow distribution without performing a pipe network calculation has been realized.
03102414 Forecasting the demand on solar water heating systems and their energy savings potential during the period 2001-2005 in Jordan Kablan. M. M. Erie,%), Con~'rrrion crnrl Mun~gc~mcirr, 2003. 44. (12). 2027 2036. Jordan is an example of a developing country that depends almost exclusively on imported oil. Luckily, Jordan is blessed with good solar energy resources. However. only 24% of Jordanian families are installing solar water heating systems (SWHS). The objective of this research is to forecast the yearly demand on SWHS by the household sector during the period 2001-2005 and to compute the potential energy savings throughout the investigated period due to the use of SWHS. It is found that the net energy collected over the entire investigated period ia about 1454.4 million kW h. In addition, the capital savings over the entire investigated period is estimated to be 46.28 million US$ if SWHS are used to heat water instead of the commonly used LPG gas cookers. The results of the research may assist decision makers in the energy sector to implement more comprehensive plans that encourage more families to install SWHS and save on imported oil.
