The Design of High Temperature Heat Pump Compressor using the Inverse Design Method
This paper presents a comprehensive design and optimization workflow for a high-temperature heat pump (HTHP) centrifugal compressor using an inverse design method. The methodology integrates heat pump cycle analysis with compressor meanline design, allowing for the simultaneous selection of refrigerants and compressor sizing in the initial design stage.
The study investigates three low global warming potential (GWP) refrigerants: R1233zd(E), R1224yd(Z), and pentane. The inverse design method rapidly generates viable design candidates, which are further optimized using an automated workflow. Computational fluid dynamics (CFD) and finite element analysis (FEA) are employed to verify the compressor performance. The designed system operates at 85°C evaporating temperature and 150°C condensing temperature, delivering a heating capacity of 1MW, suitable for various industrial processes.
