Development of a Small Solar Thermal Mechanical Pumping SystemPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 024184, 2002 ASAE Annual Meeting . (doi: 10.13031/2013.10580) @2002Authors: Dennis L. Larson, Salim Al Rawahy Keywords: Solar pumping, Rankine cycle The University of Arizona is developing a <1kW sized solar thermal mechanical pumping system that appears to have great potential for meeting small pumping requirements (~4000 liters/day with 10 m lift) in locations with adequate solar resource. This solar pumping system is believed to be applicable to many remote domestic and irrigation applications without access to electricity, relying on diesel power and/or having insufficient wind for pumping and to be a cost competitive, locally manufacturable alternative to photovoltaics. The system consists of solar collector, single piston diaphragm engine, custom valving, condenser and return pump. The piston actuates a lever connected to a lift pump. Testing in Oman is scheduled for Spring, 2003. (Download PDF) (Export to EndNotes)
