| Abstract | This research purpose is to design and construct an automatic thermal water pump (TWP) with steam-air and study the appropriate amount of air added to a steam working fluid for use within the system. Direct contact cooling was employed. The system consisted of feed water tank, liquid piston tank, heating tank, storage tank and well tank. The objective is a feasibility study of the air quantity in the LT was set at 0%, 10%, 20%, 30% and 40% with a constant discharge head of 1 m, a constant suction head of 0.8 m and 1 hours test time. However, in this research we uses heater as a substitute of renewable energy. Thermal energy input was supplied by an electric heater as a substitute of renewable energy. An operation of the pump consisted of 5 stages: heating, pumping, vapor-flow, cooling and water suction. Results of the experiment use air in conjunction with system the maximum pumping efficiency 0.01903% at quantity of air 10% the maximum pumped water 96.4 l at quantity of air 0% the maximum numbers of pumping cycles 17 cycles at quantity of air 40%. As the quantity of air increased, the numbers of pumping cycles increased but the pumped water could be reduced accordingly, which affected the pumping efficiency. However, HT temperature could be further reduced. Using air in conjunction with the steam working fluid could lower the working temperature suitable to solar application. |
