Abstract
The paper provides the results of a theoretical and experimental study of a steam jet refrigerator. A small-capacity steam jet refrigerator has been tested with boiler temperatures in the range 120-140 degrees C. The experimental data were found to be within 85% of the theoretica l values. The experiments showed that choking of the secondary flow in the mixing chamber of the ejector plays an important role in the syst em performance. Maximum COP was obtained when the ejector was operated at its critical flow condition. Off-design performance characteristic s of the system are provided.
