Résumé

This investigation deals with the design and modeling of an integrated energy system (IES) for district heating. It consists of a heat pump, district heating network, phase change material (PCM) thermal storage, photovoltaic (PV) panels, borehole, and battery. The system harnesses the power of a cascade high-temperature heat pump utilizing zeotropic refrigerants such as CO2/butane (3%/97%) and CO2/pentane (2%/98%) for low stage and high stage, respectively. The heat pump design was specifically sized to generate hot water at 100°C, coupled with a Coefficient of Performance (COP) above 3.6. The IES was simulated in Oslo, Norway, with a Matlab model over a year on an hourly basis, underlying the practical applicability to real-world scenarios. The system provides enough heat to satisfy the demand for 9/12 months of the year while also achieving self-sustainability during its operation. Zeotropic refrigerants add an extra layer of efficiency and adaptability thanks to their temperature glide. This remarkable success is a significant jump forward for clean and sustainable district heating.
