Heat pump technology is important for boosting the reduction of CO2 emissions, reducing primary energy
consumption, and increasing the amount of renewable energy used. The scope of industrial applications is also
expected to expand, further enhancing these effects. Trends introduced in industrial heat pump technology in
Japan include pioneering high-temperature heat pumps, such as CO2 refrigerant transcritical cycle heat pumps
for hot water and hot air supply, reverse Rankine cycle heat pumps for heating and cooling of circulating water,
and steam-generating heat pumps.
