Around ten percent of the global consumption of electricity is currently spent on air conditioning – by 2050 a threefold increase is expected. Refrigerants are used that partly contribute to the greenhouse effect. Consequently, the EU and other countries are gradually refraining from using these refrigerants.

Alternative refrigerants place new demands on the design of refrigeration and air conditioning systems. With the “phase down” of traditional refrigerants and the emergence of new substitutes, the EU F-Gas Regulation brings a considerable increase in costs.
