Performance of a solar water pump with ethyl ether as working fluid

摘要

This paper presentes the description and operation of a solar-powered thermal water pump with ethyl ether as the working fluid. A simple flat-plate collector with an exposed area of 1 m~2 is employed to pump water ranging form 700-1400 1/day depending upon the lift (6-10). Such a pumping system could achieve efficiency of about 0.42-0.34.
