Influence parameters on the performance of an experimental solar-assisted ground-coupled absorption heat pump in cooling operation

The experimental plant is located in a tertiary-use building in Valladolid (Spain). A model of the experimental installation has been developed using the TRNSYS software. The model has been validated with experimental results obtained in the installation for its cooling mode operation during the summer of 2011. For a defined control strategy, the influence of the generator and condenser temperatures on the heat pump COP and on the overall system energy efficiency is analyzed.
