Résumé

The performances of a solar absorption refrigerator cycle are investigated. The cycle is considered as a real irreversible plant operating in transient regime. The total entropy generation is acquired applying the two laws of thermodynamic and the performances are examined at various operating conditions. The results show that high efficiency value is obtained at high control temperature. The increase of this temperature allows reaching the minimum time to reach a prescribed cooled-space temperature. Greatest and optimal values of the stagnation temperature of the solar collector are needed to approach the real operations. The minimum time and the dimensionless size of the solar collector are significantly affected by both the cold thermal load and the thermal conductance of the walls.
