Standard system configurations reduce the design effort for single applications considerably, since sizes and layouts are stated. To identify and promote such configurations a user friendly online tool was developed to disseminate the main results of a number of simulated case studies selected through economical and ecological ratings, for different typical working conditions (i.e. application, climate, etc.).
The structure of the tool is divided into input values selected by the user (location, application, cold distribution system, heat rejection system, solar collector type) and output values given by the database (total solar fraction, cooling solar fraction, relative primary energy saved, specific primary energy saved, total electric efficiency, gross solar yield). No direct comparison between industry partner chillers is deliberately presented but the user through different configurations can use different chillers. The effects of different technological options are easily manageable by professionals and end users as a function of the system size.
