Heat pumps provide heating in winter and cooling in summer. While they’re OK for moderate climates, they are not efficient in extreme cold climates. Building on work that began five years ago, researchers at Purdue University are developing a new type of heat pump that is much more efficient and could allow residents in cold climates to cut their heating bills in half.
