TY - JOUR TI - Hybrid Heating and Cooling System with Renewable Energy Sources AU - Pater, Sebastian AU - Magiera, Janusz AU - Ciesielczyk, Michal TI - Hybrid Heating and Cooling System with Renewable Energy Sources AB - This paper presents hybrid heating and cooling system with four heating devices, three of which are producing heat from renewable energy sources. The systems operate in real conditions in residential and commercial building near Cracow. Geothermal heat pumps have an additional working mode that can be used for passive cooling during summertime for the cooling of building interiors. Results from several years of installation operation with a particular emphasis upon performance, the consumption of electricity, and the amount of heating and cooling production achieved by the individual devices have been presented.
