A METHOD AND DEVICE FOR TREATING A FLUID

摘要

A method comprising the steps of flowing a flow of relatively cold fluid along at least one photovoltaic solar panel being heated by solar energy towards and into a fluid treatment device, at least heating the flow of fluid in a fluid treatment device to divide the flow of fluid into a flow of a first fluid part and a flow of a second fluid part, flowing the flows of the first fluid part and the second fluid part from the fluid treatment device along the flow of relatively cold fluid. Before entering the fluid treatment device the flow of relatively cold fluid is preheated by the relatively warm photovoltaic solar panel and the relatively warm flow of the first fluid part and the relatively warm flow of the second fluid part.
