This thesis deals with the investigation of an absorption chiller concept, which provides cooling capacity from waste heat of an engine-driven cogeneration unit. In order to increase the efficiency of energy conversion an innovative absorption chiller is introduced in comparison to the state of the art one-stage absorption chiller. This innovative absorption chiller is based on a double-effect absorption cycle with an additional integrated one-stage absorption cycle. This allows an optimum adaptation to the high as well as the low temperature heat sources of the cogeneration unit. At the same time, this absorption chiller achieves a major flexible changeover between heating and cooling provision. The operational reliability and different possibilities of solution cycles are tested and analyzed in two pilot plants. Furthermore, an advanced high temperature generator with an adapted tube boiler is presented and tested.
