Abstract

Air source heat pumps are easily applied to buildings almost anywhere. They are widespread in milder climate regions but their use in cold regions is hampered due to low efficiency and heating capacity at cold outdoor temperatures. This article describes selected R&D activities aimed at improving their cold weather performance.
