What is it about?
This work explores how to better control and monitor a type of heat pump called an absorption heat pump. Unlike traditional electric heat pumps, absorption heat pumps use a special fluid mixture—in this case, water and a substance called Carrol™—to recover waste heat from industrial processes and make it usable at higher temperatures. The study focuses on designing the instruments and software needed to control how this fluid mixture moves and behaves inside the pump. By simulating different conditions and calibrating temperature sensors, the researchers built a computer-based system to track energy flows and mass balance in real time. This makes it possible to run the pump more efficiently and plan for automation in future systems.

Why is it important?
Recovering waste heat is a key strategy for improving energy efficiency and reducing environmental impact in industry. However, controlling absorption heat pumps is technically complex because many variables must be balanced at once. This study is important because it provides a preliminary but practical method for monitoring and controlling these pumps using object-oriented software and real-time data acquisition. The approach helps shorten the startup process, improve stability, and lays the foundation for automated systems. In the long run, this kind of research can contribute to cleaner technologies, reduced energy waste, and more sustainable industrial operations.
Perspectives
The paper represents an early but significant step toward integrating advanced instrumentation and computer-based control into absorption heat pumps. While it focuses on the water/Carrol™ fluid pair in a single-stage system, the methodology could be extended to other working fluids and more complex systems. Future work will likely refine the automation and test real-world applications at larger scales. This positions the research within the broader field of applied thermodynamics, renewable energy, and sustainable process engineering.
