Abstract
The transition from a fossil fuel-dominated heating market to a renewable system rep-resents a significant challenge for the present era. The integration of high-temperature heat pumps (HTHP) is a crucial aspect of this transition and cannot be overlooked. In the absence of a substan-tial corpus of experimental data, it is imperative that models demonstrating resilience and robust performance be employed in the design and planning of heat pump projects. The compressor rep-resents the most significant and intricate component within the heat pump cycle, with a multitude of available technologies currently on the market. This submission focuses on reciprocating piston compressors, which are widely used in heat pump processes due to their flexibility and extensive range of available sizes. The literature demonstrates a variety of approaches to simulating the per-formance of the compressor, including physical models, empirical models, and semi-empirical models. The objective of this study is to develop a semi-empirical model based on experimental data obtained from a test rig and to convert it into a scalable polynomial model in accordance with the approach proposed by Kaufmann et al. [1]. Following the validation of the model with the test rig, a comprehensive validation with manufacturer data will be conducted. This will result in the creation of a low-order model that combines the advantages of low computational cost, high accu-racy, physically correct predictions over a wide operational range and scalability to different ma-chine capacities. Additionally, the variation of working fluids will be analysed and validated using datasets provided by manufacturers.
