Abstract

The continuous search for the effective cold generation methods resulted in the creation of thermally driven ejector refrigeration systems (ERS). Producing cold at various temperatures, the ERS serves to save electric energy and reduce greenhouse gas emissions. The theoretical analysis of the ejector cycles carried out for various ERS has proved its capability to generate the cold at +12°C to –40°C, reaching the COP values at 0.7 to 0.1 respectively. The combined cycles of water conversion, heat and cold production appear to be especially effective.
