β¦ Synopsis
of air-conditioning, there is a report on how performance differs according to outdoor summer thermohygrometric design conditions, such as those indicated by UN1 10339, by ASHRAE and by the processing of TRY data. Finally, this paper discusses the optimal choice of design conditions according to the type of application.
