Markets for heat pumps have been expanding at a healthy rate over recent years. Two major drivers have been uncertainty over energy prices and growing environmental and climate concerns, which have highlighted the need to save energy and optimize renewable energy sources. Heat pump markets in many countries have focused chiefly on residential heat pump
applications. Turning to heat pumps for high capacity in commercial and industrial applications has been much less of a natural reflex. Increased energy cost and awareness of the need for reduction of CO2 – emissions are drivers for large heat pumps. The main market barriers are expected to be lack of experience and thus lack of acceptance in market. This paper summarizes the objective of a new started IEA Annex to reduce the use of
energy and greenhouse gas emissions by the increased implementation of large heat pumps. This paper will also highlight some successful applications.
