Performance Variability of Air-Water Heat Pumps in Cold and Warm Years Across European Climate Zones

Опубликована: Янв. 1, 2025

This study examines the performance and economic feasibility of air-water heat pumps (ASHPs) across diverse European climate zones under varying energy price scenarios. Focusing on four regions (Poland, Lithuania, Croatia, Spain), analysis evaluates Seasonal Coefficient Performance (SCOP) Net Present Value (NPV) during cold warm years. Results indicate that SCOP is highly sensitive to climatic variability, with efficiency decreasing by 40–50% in colder years, while remaining stable warmer climates such as Spain. Economic reveals high electricity scenario (S1), only Spain achieved positive NPVs both periods, smaller (8 kW) being most cost-effective. Conversely, gas (S2), all demonstrated NPVs, particularly for larger units (13 These findings emphasize importance adapting pump sizing local conditions implementing policies balance prices. Future studies should aim develop more comprehensive approaches capture interplay between variability feasibility.
