Thermodynamic and economic analysis of the absorption-ejector hybrid refrigeration cycle with R22-degdme

摘要

The absorption-ejector hybrid refrigeration cycle that could obtain high COP value,is a new kind of refrigeration cycle and it consists of two subcycles - a modified single-effect absorption cycle and a jet ejector cycle.It is a four-pressure hybrid absorption refrigeration cycle,and could be simplified as a three-pressure hybrid absorption refrigeration cycle when liquid ejector is eliminated.Based on thermodynamic energy analysis and economic analysis.the absorption-ejector hybrid refrigeration cycle has been studied and the working pair R22-DEGDME is used in the system.
