One of possibilities of reduction of F-gas emission is application of low grade heat to drive the refrigeration systems as well as application of natural or low GWP working fluids. The own experimental investigation of ejector refrigeration system operating with refrigerant R-1234ze(E) are presented and discussed. The system is driven with low grade heat source of temperature below 70 degrees C and thermal capacity approximately 90 kW. The experiments covered the effect of condensation, evaporation and generation temperatures on the capacity and thermal efficiency of the ejector refrigeration system operating for air-conditioning purposes. Obtained results showed that the proposed system may be thought as the promising thermally driven refrigeration system with application of low grade motive heat sources. (C) 2016 Elsevier Ltd.
