This research article proposes the use of a box-type solar heater for the disinfection of domestic roof-harvested rainwater in Ibadan, Nigeria. Solar water heater can be used to pasteurize water thereby destroying bacteria and viruses when heated to temperatures of about 65°C.
This presentation, given by Dr. Uli Jakob of Solem Consulting, at the AHK (German-Australian Chamber of Industry and Commerce) conference in Sydney in March 2014, gives an update on the technologies and perspectives of solar cooling systems. It covers the different technologies used, such as sorption chillers, integrated hydraulic units and standardized solar cooling kits. It also provides a short overview of solar collector technologies for solar cooling.
