✦ Synopsis

Thermodynamic analysis has been carried out in detail, to predict the performance of a solar thermal water pump working at dierent discharge heads. It is shown that the heating time of the working ¯uid 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 ¯uid being loaded in the system initially. Similarly, it is observed that an optimal cooling coil area dictates the eective 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 ¯uid to be loaded in the system and the optimum cooling coil area.
