The impact of climate change on air source heat pumps
Climate change will impact the building sector, but the related consequences are not fully known, especially at energy system level. This paper investigates the effect of a changing climate on heat pumps, worldwide recognized as one of the most promising technology to decarbonize the building sector. The research aims to understand how air-source heat pumps (ASHPs) will perform within climate change depending on locations and scenarios. ASHPs are considered in several locations around the world selected to cover the climate variability of the Köppen-Geiger climate classification. Future projected climate scenarios to the years 2030, 2050, 2070 are studied under three Representative Concentration Pathways (RCPs: 2.6, 4.5, 8.5) that reflect an increasing climate change severity. The forecast analysis is conducted in terms of ASHPs seasonal coefficients of performance, working hours, seasonal and annual energy consumption. Differences are found among locations, scenarios, and RCPs. The research illustrates how the two effects of heating decrease and cooling increase offset or whether one seasonal consumption prevails and where this occurs. The general trend foresees a noteworthy reduction of winter energy consumption in all climate zones. Higher decreases are found for RCP 8.5 compared to RCP 2.6 and RCP 4.5 scenarios, for both radiant floor panels and fan coils. Concurrently, a major rise is estimated in cooling consumption in almost each climate zone, with wider differences within RCP 8.5. ; JRC.C.2 - Energy Efficiency and Renewables
