Quality Level Assessment of Sorption Chillers Installed in Solar Cooling Plants

The use of reliable, representative and reproducible data for the assessment of the quality level of HVAC systems and components on seasonal basis is crucial especially in view of the obligation of energy labelling, which is due by September 2015, and of the market surveillance. An analysis on the current normative framework dedicated to sorption chiller has revealed that no exhaustive references for sorption technologies and applications exist. Therefore, two test procedures aimed at the mapping of performances of sorption chillers at full and part load have been developed. The procedures developed take into account also different machines operating modes (i.e. continuous and discontinuous). A first attempt of validation of the test procedures has been carried out and here presented.
