What is it about?
Double absorption heat transformers are systems that recover low-temperature waste heat and upgrade it to higher temperatures for reuse in industrial processes. This paper focuses on defining the key parameters that describe how these systems work, such as the coefficient of performance (COP), flow ratio, and gross temperature lift (GTL). By carefully analyzing these indicators, the study provides a clearer understanding of how to design, evaluate, and optimize double absorption heat transformers. The results enable engineers to predict system efficiency, compare performance under various conditions, and identify strategies to maximize heat recovery.

Why is it important?
Waste heat recovery is crucial for reducing energy consumption and greenhouse gas emissions. This work is important because it establishes a standardized framework of parameters for evaluating double absorption heat transformers, something that had not been clearly defined before. By making system evaluation more precise, the study supports the development of more efficient and practical waste heat recovery technologies. These insights can accelerate the adoption of heat transformers in industry, helping to lower energy costs and improve sustainability.
Perspectives
This research provides the groundwork for a consistent evaluation of advanced heat recovery systems. Future work could apply these parameters in large-scale pilot plants, integrate them into simulation tools, or extend them to other thermal systems like solar-driven chillers. By clarifying how to measure and compare performance, the study strengthens the path toward wider industrial use of heat transformers.
