Abstract: This paper presents the annual performance of a proposed reversible water/LiBr absorption heat pump connected to a district heating network for space cooling, heating, and domestic hot water (DHW) applications. A typical small-office building located in two cities (Barcelona and Berlin) with different climate zones was considered in this study. The absorption heat pump operated in heating and cooling modes of operation depending on the needed demand type in the building. The dynamic modelling and simulation of the absorption heat pump driven by the district heating network were carried out for each operational mode. The obtained simulation results are seasonal COP in heating and cooling mode as well as the amount of potential DHW production throughout the year. Moreover, the annual operation time and primary energy ratio of the proposed system were obtained. Then, the primary energy ratio is compared with conventional buildings’ cooling and heating systems. It is found that the proposed system has an increasing operation time up to 63% and consumes less primary energy with a reduction of up to 30%. Thus, the development of this type of system contributes towards the reduction of fossil fuel consumption for the space cooling and heating sector of non-residential buildings.
