IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask C1 Report, 31 October 2010
Due to the intermittent, quasi continuous operation of such an adsorption chiller, the
temperatures and thus the power in the three hydraulic circuits are fluctuating. Figure 13
shows a typical temperature curve of an adsorption chiller.
Depending on the construction type, the hydraulic circuits may be interrupted during the heat
recovery phases.
