Abstract: The need for retrofitting of residential buildings with energy efficient solutions requires for the development of a wide range of solutions, suitable for different climates and buildings. In the present paper, a concept based on a gas-driven sorption heat pump using geothermal source for evaporation is presented. A dynamic lupedparameter model was implemented in Dymola and used to verify the flexibility of the system in terms of response to variable load and comfort conditions. The outcomes of the activity will be used to propose an improved design of the system.
