On the Complex Indicator of Perfection in Selecting Environmentally Acceptable and Thermodynamically Effective Working Substances for High-Temperature Heat Pumps

The article discusses the new approach to the selection of a thermodynamic effective and environmentally acceptable substance for a high-temperature heat pump. The complex indicator of the perfection of working substances for high-temperature heat pumps is proposed, which makes it possible to assess the influence of the operation of heat pumps on the greenhouse effect, taking into account their thermodynamic efficiency and characteristics of the heat pump unit life cycle. An example of the choice of a working substance for a high-temperature heat pump distiller with a boiling point of the working substance 90°C is given.
