AN OVERVIEW OF THE RESEARCH AND THE MARKET FOR HEAT PUMPS IN KOREA


The heat pump is one of the most effective among those technologies for carbon
dioxide reduction. However the popularity of heat pumps is not so common because of
geographical, economical and technical reasons. In Korea, during winter season the ambient
temperature is very low (about -5°C) and the unit charge of electricity is expensive, the direct
heating from boiler costs less than that of a heat pump system. Continuous efforts have been
made by researchers for the last decade to overcome these obstacles. Nowadays the heat
pumps systems for specified locations such as cold area, multi-zone and module-based
systems with high performance are available in the market. Also with the development of IT,
the optimized control techniques are developed and the application of heat pump system
became easier. It is commonly used in GSHP with the policy of government. In this article an
overview of the researches and the market trend about the heat pumps in Korea are
described.
