Theoretical Study of a Steam-Ejector Refrigerator

Satha Aphornratana


This paper provides a theoretical analysis of a seam-ejector. An ejector model is developed based on one-dimensional ideal gas theory which was first introduced by Keenan. This theory is modified to include losses associated with the primary nozzle, mixing chamber, and diffuser. This ejector model is then used to analyse thermodynamic performance of a steam ejector refrigeration cycle over a range of operating temperatures. The theoretical results are compared with the experimental results obtained from the literatures.
