GreenHVAC4Rail Gesamtoptimierte emissionsfreie Heating Ventilating und Air Conditioning-Anlage für Rail-Anwendungen

GreenHVAC4Rail focuses on the development of an environmentally friendly air conditioning system with integrated heat pump for use in rail vehicles. So far synthetic HFC refrigerants with a very high global warming potential (ca. 1500 CO2 equivalent) have been used. This now is replaced by the natural refrigerant CO2, which is obtained as a residuary product from industrial processes, avoiding any emission of harmful HFC greenhouse gases. The heat pump, in turn, saves up to 40% of electric power as compared to current commonly used electric heating systems, especially in winter time. At the end of this project a prototype system with newly developed components will be available. This makes possible an early world market launch of innovative CO2 air conditioning systems, developed and produced by an Austrian consortium.
