Author(s) : WATANABE C., UCHIYAMA Y., HIRANO S., et al.


Industrial heat pumps for hot water supply, hot air supply, heating of circulating hot water and steam generation have been developed with a pioneer spirit in Japan. This paper describes the industrial heat pump technology reported by the IEA HPP Annex 35 national expert meeting of Japan. Firstly, a trans-critical CO2 cycle heat pump, single-stage compression reverse Rankine cycle heat pumps, two-stage compression reverse Rankine cycle heat pumps and a hybrid vapor recompression system are presented as the high-temperature heat pumps for industrial processes. Secondly, the industrial applications of these heat pumps are described.
