Absorption chiller cooling is a recent technology based on a source of heat coming from hot water as driving energy. This hot water can come from renewable sources such as solar heating or from district heating networks as a by-product of combined heat and power plants (CHP). This technology reduces notably the electrical consumption in comparison with traditional compression cooling technologies. These benefits usually have their counterpart, which is a larger investment. This thesis describes some of the test sites that TU Berlin is currently operating in Germany and Jordan and describes some of the advanced control strategies that have been designed to regulate the operation of certain components of the system. Further in this work, specific values of system components consumption are analysed in order to explain the behaviour of the system under different operation conditions when some strategies are active or not. The thesis shows that when advanced control strategies are active in the sites and no abnormal operation conditions are given, the specific electrical consumption of the components involved in the strategies is significantly reduced, helping the absorption cooling plant to be more energy efficient.
