Experimental Investigation of a Small Capacity Steam-Ejector Refrigerator

Abstract

This paper describes an experimental study of a steam-ejector refrigerator. A 1kW cooling capacity refrigerator has been tested with boiler temperatures from 120 /span>C to 140 /span>C and evaporator temperatures from 5 /span>C to 10 /span>C. The cooling capacity and COP were found to be very sensitive to all operating temperatures. The choking of the working fluid in the mixing chamber of the ejector was found to be very important to the system performance.
