Directly coupled solar thermal water pumping concepts for agriculture. Final report, October 1978-May 1979

PDF Version Also Available for Download.

Description

The directly coupled solar thermal water pumping system has been analyzed for both performance and cost. Performance estimates for a real operating system exceed 8% for the typical environmental conditions expected. The cost of such a system, using currently available flat-panel collectors, is highly competitive with alternative, remote location, water pumping systems. Although the system has a fairly low relative cost, there are areas such as valve and actuator cost that have a high potential for reducing system cost, especially for smaller systems. The performance of the system can be improved by high-performance, moderate-temperature collectors such as evacuated glass tubes. ... continued below

Description

The directly coupled solar thermal water pumping system has been analyzed for both performance and cost. Performance estimates for a real operating system exceed 8% for the typical environmental conditions expected. The cost of such a system, using currently available flat-panel collectors, is highly competitive with alternative, remote location, water pumping systems. Although the system has a fairly low relative cost, there are areas such as valve and actuator cost that have a high potential for reducing system cost, especially for smaller systems. The performance of the system can be improved by high-performance, moderate-temperature collectors such as evacuated glass tubes. The advantages of the directly coupled solar thermal system are simplicity and limited failure modes. Results of the experimental phase indicate that the analytic models provide an accurate estimate of achievable system performance.
