Summary

Ammonia is a natural working fluid, and has been used in industrial refrigeration plants for a long time. Although it has significant thermodynamic and environmental advantages, it has not been used in small heat pumps so far. The reason for this is the need to use copper-free materials and the fear of leaks. The Institute of Energy Technology at the University of Applied Sciences in Rapperswil (Switzerland) is presently conducting a research project for the development of a single-stage compression ammonia heat pump with arotating blade compressor and a thermal power of 17 kW.
