Design and experimental investigation of an ejector in an air-conditioning and refrigeration system.

Summary

The paper discusses the conservation of energy in a refrigerant ejector refrigerating machine using heat driven from the concentrator collectors. The working refrigerant was R113. The design of an ejector operating in an air-conditioning and refrigerating system with a low thermal source (70 to 100 deg C) is presented. The influence of the three major parameters (boiler, condenser, and evaporator temperature) on the ejector efficiency is discussed. Experimental results show that the condenser temperature is the major influence at a low evaporator temperature. The maximum ejector efficiency was 31%.
