High-Temperature Heat Pumps

This project develops and demonstrates a heat pump portfolio that exploits the variety of natural refrigerants to provide optimal solutions for a variety of applications. The portfolio is based on natural refrigerants, while three pilot plants are going to be developed and tested. The three pilot plants are using R718, R744, and hydrocarbons.
