    This paper presents a theoretical calculation method for designing the steam ejectors for refrigeration applications. The working fluid is assumed to be an ideal gas. The flow processes inside the ejector are analyzed by using thermodynamic and ideal gas equations. The advantage of this paper is that the presentation of the theory and calculation procedure are very easy to understand and follow. A design criterion of a steam ejector is also provided. The experimental results at several operating conditions are used to validate the theoretical results. The validation results show that this calculation method can be used as an efficient tool in the design of steam ejectors.
