Summary

Steam is one of the most important energy carriers in industrial processes. For example, steam is used for sterilization, cooking and drying processes and as a heat transfer medium for various processes. Fossil fuels are often used to generate steam, but the use of fossil fuels, especially in industry, must be reduced in the future to reduce CO2 emissions and to achieve climate targets. Heat pumps are already being used successfully in industrial applications, valorizing waste heat. With a high temperature heat pump, waste heat can be used to generate steam. This extension of the application range of heat pumps will provide a further contribution to achieving climate targets. A model of a steam generating high temperature heat pump was elaborated to study the technology under different operating conditions. This contribution shows the simulation results of a steam generating high temperature heat pump system with different refrigerants. The results are compared in terms of COP and compressor displacement. The goal is to identify the most appropriate refrigerant for a specific steam pressure.
