Summary

Among the various possibilities for air cooling, the use of solar power to drive trithermal systems is rather interesting, especially considering absorption cycles. These latter are technologically mature and particularly used all other the world. Generally designed for nominal conditions, these machines are submitted to transient temperature and heat flux especially in the case of solar driven cycles. Being able to predict performances in such conditions reveals rather difficult. The way we chose to overcome this, consisted in modeling and numerically simulating its behavior. It has been applied to a manufactured machine that has been tested under static and dynamic conditions to identity missing or unknown parameters. This work has been done and simulated results reveal quite accurate with experiments even when external conditions applied to the machine are varying.
