AN OVERVIEW OF NATIONAL R&D PROJECTS IN HEAT PUMP TECHNOLOGY IN JAPAN


Heat pump technology in Japan has developed as the core technology of the national “Moonlight
Program/Energy Conservation Project” as illustrated by the “Super Heat Pump Energy Accumulation
Project” (1984-1992). Recently, for the purpose of reducing greenhouse gas emissions, CO2 working fluids
have become the focus, and several combinations based on CO2 working fluids have been developed and
introduced.
