Thermodynamic analysis and optimization of a solar thermal Water Pump
Applied Thermal Engineering, 2001Co-Authors: Y.w. Wong, K. SumathyAbstract:Thermodynamic analysis has been carried out in detail, to predict the performance of a solar thermal Water Pump working at different discharge heads. It is shown that the heating time of the working fluid and the condensation time of the spent vapour play an important role in determining the number of cycles that a Pump can perform in a day. The heating time in turn depends on the amount of working fluid being loaded in the system initially. Similarly, it is observed that an optimal cooling coil area dictates the effective condensation time. Hence, in the present work, an optimum design has been outlined for a solar thermal Water Pump, both in terms of the amount of the working fluid to be loaded in the system and the optimum cooling coil area.

Effect of discharge head on the performance of a solar Water Pump
International Journal of Energy Research, 1994Co-Authors: K. Sumathy, A. Venkatesh, V. SriramuluAbstract:Presented in the paper is a brief description of the solar thermal Water Pump and its operation. The performance of such a solar Water Pump working on a flat-plate collector of exposed area of 1 m2 is studied for three different discharge heads, namely 6, 8 and 10 metres. The thermodynamic analysis reveals that, while the number of cycles and the quantity of Water Pumped per day decrease with an increase in the discharge head the overall efficiency increases.

Studies on a metal hydride based solar Water Pump
International Journal of Hydrogen Energy, 2004Co-Authors: Debashis Das, M. Ram GopalAbstract:Abstract A metal hydride based solar Water Pump has been simulated and effects of various design and operating parameters have been studied. The study shows that if the cost of metal hydride is much higher than the collector and/or land cost, then one should use more number of thin hydride bed solar collectors for best performance. On the other hand, if the solar collector and/or land cost is much higher than hydride material cost then thick bed solar collectors are preferred. It is possible to optimize the system performance for different discharge heads by varying the enthalpy of formation of metal hydrides, which is a unique characteristic of the hydride based solar Water Pump. The study shows that depending on the design and operating conditions, it is possible to Pump as much as 3000 l of Water in a day over a height of 15 m using 1-m2 collector area. The maximum overall thermal efficiency of the metal hydride based solar Water Pump was found to be about 1.5%.
