IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date:… respect to the autonomous solar thermally driven cooling, can be applied very well to the conditions of the cooling loads in the building. The system serves at the same time as support in the education of students from the Technical College. This results in a big multiplier effect. In case the system should be transferred to a similar application it can be simplified considerably, as for example by installing just one chiller (for appropriate cooling loads) and thereby reducing respectively the hydraulic complexity. On the hot water part, the system is already simplified by being a pure water system and therefore not needing a heat exchanger in the collector circuit. In the following points optimization potential can be given or a further revision is reasonable: - possibly testing of the chiller operation with higher driving temperatures; - a further examination of the second chiller’s capacity in the coming cooling season; - a further examination of the backwashing intervals in the cooling water circuit: at present a high fresh water demand is required. There might be found an optimum between water consumption, backwashing intervals and pollution degree in the cooling water circuit. - checking if a careful pruning of the trees shading the collector is possible. Estimations show that in comparison to conventional heating and cooling systems primary energy savings and CO 2 emission avoidance was achieved. 8 Bibliography E. Wiemken, J. W. Wewiór, A. R.
