Currently

China's energy consumption is heavily reliant on coal

which is difficult to replace. The development of non-fossil fuels faces multiple constraints

and the industry is adversely affected by the issues of high energy consumption

high emissions

and low energy efficiency. Therefore

innovative low-carbon technologies urgently require further development. Heating accounts for half of all energy consumption; therefore

low-carbon heating is important for achieving carbon neutrality. To meet the capacity and temperature requirements of industrial heating

high-temperature water/steam heat pumps must be developed. This paper presents an analysis of the current status of industrial heat pump technology

including system cycles

refrigerant compression technology

and steam compression technology. Based on the development status of fourth-generation low-global warming potential refrigerants

the corresponding heat pump technologies should be well developed. Furthermore

industrial heat pump development prospects are discussed based on the development status and applications. Finally

application scenarios are predicted based on the market capacity and carbon reduction potentials.
