Abstract

Heat pumps enable the use of “freely” available heat at lower temperatures to provide heat at higher
temperatures (which can be utilized e. g. for process heat, district heating). Therefore, in times of increased
environmental awareness and resource scarcity, the heat pump market is experiencing massive demand and
is crucial for achieving climate goals as well as energy independence. Heat pump components usually have a
customized design to ensure good performance in the intended operating range. This applies particularly to
thermally driven absorption heat pumps which use H2O/LiBr-mixtures as working fluids since the fluid
properties (e. g. density) of the refrigerant change significantly at varying temperatures.
In this paper, the operating behaviour (e. g. capacities, efficiencies) of a H2O/LiBr-absorption chiller (nominal
evaporator capacity: 15 kW) is analysed in heating mode at varying operating conditions using measurement
data from a test bench.
