✦ Synopsis
Non-convecting solar ponds have the potential of provrdlng low-temperature heat well helow current fuel prices. The development of multi-etfect distillation plants operating below IOO'C alloys solar ponds to be considered as the heat source. The paper discusses optimization of the size of the pond and the number of effects used, taking into account the large variation of pond heat output between summer and \inter. One result is that, for current cost data, it pays to oversize the pond-leading to some rcjcction of heat in the summer (which IS referred to as peak clipping--because this leads to a better utilization of the desalination plant and a reduction in the summer-winter yield ratio. For Israel conditions. the peak clipping reduces the summer-winter output ratto from 4:l to approximately 2:i with the summer output maintained for X0-230 days in the year.
