摘要
This paper describes the calculation of main cross sections of a steam-ejector, operating in a refrigeration system. For the detailed calculation of ejector a method has been developed which employs functions describing the thermodynamic properties of steam. The influence of three major parameters: generator pressure.. condenser and evaporator temperature on cross sections of ejector is discussed. The design conditions were: generator pressure (6-8 bar), condenser temperature (40-50 degreesC) and evaporator temperature (4-10 degreesC). It is confirmed that the dimensions of ejector depend on the operation conditions. (C) 2004 Elsevier Ltd. All rights reserved.
