Ejector Refrigeration Cycle with Internal Cooling

摘要

This paper introduces a new refrigeration / thermodynamic cycle (Ejector refrige ration cycle with internal cooling) and its possible applications, as well as compares it with the absorption refrigeration cycle for the same generator temperature. As it is generally known, an ejector refrigeration system (ejector chiller) utilizes thermal energy (solar-thermal energy, geothermal energy, waste heat from thermal / nuclear power plants, as well as foundries, etc.) from a heat source for cooling buildings / industrial facilities. Compared to conventional chillers, ejector chillers have a pump and an ejector (thermal compressor) instead of conventional (mechanical) compressor. F or the same refrigeration effect, the work of a pump is significantly lower than the work of a mechanical compressor. This results in reducing electric power input for a refrigeration system while maintaining the same cooling capacity. As the efficiency of the conventional ejector refrigeration system is too low, the conventional ejector (thermal compressor) is replaced with an ejector with internal cooling.
