| Abstract: | The use of the environment-friendly and natural refrigerant ammonia (R717) for industrial heat pumps is described. Compressors for higher operating pressures equivalent to 40 bar have been developed and characteristic data such as COP, performance and operating limits are specified. The operating data from two application examples are presented. |
