Recent Development in Heat Pump Technology in Japan

Since the nuclear disaster caused by the Great East Japan Earthquake in 2011, energy supply problem in Japan has been grave. Currently all nuclear power plants are out of operation, majority of power supply are by-fired power generation by fossil fuel. Under this situation the compatibility with environmental issues, energy saving strategy is very important. In this article, the recent progress of heat pump technology following Japanese
policy of energy saving including the elements fundamental research is described. As a conclusion, it should be noted that the future development efforts more research is needed, but the seedlings of technology breakthrough is expected to realize in basic research.
