Moreover, a solar cooling system can also be used to provide heat for space heating, in the case of working in heat pump mode. Besides theoretical investigations practical experience is required to evaluate the performance of solar cooling in the field. This document presents the main results from a solar cooling installation for canteen cooling, which is in operation since 2007. The data evaluation shows a seasonal electrical performance factor of 26.1 for space heating and 6.5 for space cooling. A seasonal thermal performance factor for cooling of 0.4 has been determined
