Solar still

A parametric investigation was theoretically performed for the vertical multiple-effect diffusion-type solar still, which consists of a number of vertical partitions in contact with saline-soaked wicks with narrow gaps between the partitions, coupled with a heat-pipe solar collector. The proposed st

The transient performance of a stepped solar still with built-in latent heat thermal energy storage was studied. The still was designed for heating and humidification of agriculture greenhouses (GH) in remote areas. The solar still consists of five stepped basins with an inclined glass cover and is

A numerical study has been carried out to investigate the transient thermal performance of a naturally circulated humidifying/dehumidifiying solar still. A comparison of forced circulation performance and the influence of different environmental, design, and operational parameters on the still produ

Solar distillation is one of the important methods of utilizing the solar energy for the supply of potable water to small communities where the natural supply of fresh water is inadequate or of poor quality, and where sunshine is abundant. Solar energy utilization in two different types of solar sti

Technology for solar desalination has been studied for a long time as a process friendly to the environment and also energy saving. We found a new aspect by diverting attention from industrial mass production systems to the consumer’s life-style and resource recycling problems. Thus, desalting solar

We proposed a newly designed, compact multiple-effect diffusion-type solar still consisting of a heat-pipe solar collector and a number of vertical parallel partitions in contact with saline-soaked wicks. The solar collector and the vertical multiple-effect diffusion-type solar still can be folded o

A simple and efficient method for the behavior description of solar stills, developed on the basis of extensive testing, is theoretically and experimentally evaluated. The method relates the main climatic data and operating conditions of the still with distilled water output in daily and night base

A conventional solar still produces 6 litres of fresh water per square metre per day of collector surface. With heat recovery and air mass circulation we can reach up to 20 litres m3/d. The quality of the processed water is always very high so that the investment costs are justified. This depends on

In the present paper a techno-economic analysis of a multi-stage stacked tray (MSST) solar still coupled with a solar collector has been developed. The thermal model developed earlier by the authors for predicting the system performance has been used here also; the model considers transient heat and
