Abstract

In the present study, the performance of a small saltless solar pond augmented by planar reflector is presented. Experiments are carried out in the Faculty of Engineering, Mansoura University, Egypt (31O N). The experimental pond has a surface of 1.23 m x 1.23 m and 0.83 m water depth. A glass mirror with 1.6 m height and 2.5 m width is supported in a common edge with the pond surface. The glass reflector is south facing and vertical in position. Plastic films are used as a top covers for the pond surface. Measurements of solar radiation, ambient temperature and water temperatures at different heights in the pond are carried out. Measured augmented solar radiation is compared with that predicted by the radiation enhancement model. 
The comparison has shown a good agreement between the measured and the predicted data. The temperature gradient through the storage zone of the pond ranges around 5 Co and the upper layer of water is highly dependent on the ambient conditions. Temperatures of the plastie layers are presented during the day time, and also during 1!ie build-up period. Water temperature on the pond surface of more than 60 °C could be attained in October, with a pond efficiency ranges from about 50 up to 66%.
