Summary:

Cryogenic cooling of infra red detectors is a well know requirement and need for many instruments in space application. The need for higher performance and long-life cryogenic cooling system, along with already stringent requirements for vibration, compactness, and mass, is self evident in spacecraft instruments especially for long space missions. It is therefore an object of this study to provide a system that has the potential to meet these challenges.A new absorption based cryocooler is presented and studied. Different absorption working fluids are selected and studied.Thermodynamic state performance and major items of the design specifications are described and presented. The main characteristics of the absorption system in this study are the lowest temperature that could be reached in the evaporator side and the nature of the working fluid mixture. A maximum of 100 W cooling capacity in the evaporator side is considered
