...H. Tabaei; M. Ameri In this work, the experimental results of a designed and installed photovoltaic water pump system with static concentrator are presented. The tests have been conducted in outdoor condition in Kerman (Latitude 30 deg 17′ and longitude 57 deg 50′), Iran. The performance...

...K. Mahkamov; E. P. Orda Solar thermal water pumps are low cost and low maintenance devices with a pumping capacity of 0.2 - 1 m 3 /hour at a dynamic head of 1.5–5 m. The working fluid in the thermodynamic cycle is an air-steam mixture. In this paper we suggest a simple mathematical model...

...E. Orda; K. Mahkamov Solar water pumps, based on electro-mechanical pumps powered by PV arrays, are commonly used and commercially available. However, one of the difficulties for their wider application in developing countries, where there is a high average insolation, is their relatively excessive...

... energy systems have been used for water purification, graphs contained in the paper can be used to determine the feasibility of powering other electrical loads. Combining a 100-W solar-PV system with a 500-W wind turbine resulted in pumping and purifying enough water to satisfy the potable water...

...T. D. Short; R. Oldach Solar (photovoltaic) powered water pumps could be a real instrument for the alleviation of water related deaths and illnesses in developing countries through the provision of clean water. However, despite the benefits that access to sustainable potable water supplies can...

...M. Liu A new variable water (VW) flow system for chilled water system application is presented. Design, operational, and control issues are discussed. Analytical models of pump power and evaporative temperature are developed. The VW systems consume considerably less pump and compressor energy than...

...Daniel L. Barth; James E. Pacheco; William J. Kolb; Earl E. Rush A new hot-salt pump has been developed for molten-salt solar power tower applications that will reduce the capital cost of the plant, eliminate many of the piping, valve and sump problems associated with the handling of molten salt...

...Derek Baker; Gary Vliet Component failures and system performance degradation in SHW systems due to scaling are common in areas with hard water. It appears that many valve and pump failures on the potable water side are related to scaling, and any scale build-up on heat transfer surfaces...

...Sathyajith Mathew, Assistant Professor,; K. P. Pandey, Professor, A method for predicting output of simple multi-bladed windmill mechanically coupled to a reciprocating pump is proposed. The present method adopts an integrated approach by considering the interaction between the rotor, pump...

... pressure pump crucially affect energy consumption. The desalination cost also has been estimated for a small scale system that linearly scale with the TDS value of the feed water. [S0199-6231(00)00104-0] Contributed by the Solar Energy Division of The American Society of Mechanical Engineers...

... substances would enable the greatest specific work output to be attained. For this purpose, a generic machine is visualized, in which the expanding element is coupled with a driven element, represented in the form of a double-acting reciprocating pump. In practice, this might be a hydraulic pump...

...C. L. Putta Swamy; Bhim Singh; B. P. Singh; S. S. Murthy This paper describes the experimental study carried out on a Permanent Magnet Brushless DC (PMBLDC) motor coupled to a pump load powered by a Photo Voltaic (PV) Array for a Water Pumping System. A simple low cost controller has been designed...
