IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date:… necessary (> 70 °C) and a wet cooling mode in the h eat rejection. This value is clearly over the maximum daily value of the COP el in August 2009 with 2,3. • Due to the water temperatures in all three hydraulic circles (cold water, heat rejection and hot water circle) of the adsorption chiller daily COP th were measured in summer 2010 within the range of 0,16 to 0,58. The nominal COP th is about 0,56. • The plant optimization attempt, by using variable speed control of the heat rejection fans didn´t work due to the lack of coupling between the adsorption chiller control and the system control; on the contrary, the COP el decreased during the variable speed control mode. Generally, the usage of a system controller including the chiller control must be recommended to avoid such errors. 6 Publications A. Preisler, M. Brychta, F. Dubisch, F. Stift, T.
