Résumé

This paper aims to present a convenient way to improve the development process of vapor compression cycles, heat pumps specifically, by using transient and dynamic simulations. These capabilities are applied to develop a workflow for the design of heat pumps seamlessly integrating both types of simulations into the design process. One part of the workflow focuses on the steady analysis for design exploration, and charge optimization. Thereafter, a selected set of optimized systems is evaluated using dynamic simulations for long term performance analysis. The mentioned workflow was applied for the simulation of a heat pump system. The study demonstrates a potential enhancement in selected Key Performance Indicators (KPIs), specifically Coefficient of Performance (COP), Heating capacity, and Seasonal COP. This improvement is pronounced when accounting for both the inherent design restrictions and the variability in performance conditions. The findings underscore the importance of integrating design considerations and accounting for real-world variability in evaluating and optimizing the performance of heat pumps.
