Abstract
One of the most important steps we can take to minimize global warming is to become more energy efficient. An important example with potential for improvement is the large amount of energy wasted through waste heat streams in industry. For a long time there has already existed a solution that can efficiently upgrade waste heat streams to useful levels – heat pumps. However, heat pumps are rarely applied in industry. There are various reasons for this, including lack of knowledge and increased complexity. Another major reason is the long payback periods. This work focuses on a promising option that, for certain applications, can outperform traditional technologies by having a higher Coefficient of Performance (COP) and reaching higher temperatures: compression-resorption heat pumps (CRHP) using wet compression.
