Thermodynamic Analysis of a Single-Stage Absorption Refrigeration System Using (HFC-Organic Absorbents) as a Working Fluids Assisted by Geothermal Energy

摘要

This work is presented as a model of operation of an absorption chiller uses heat energy of geothermal sources in Algeria. The effectiveness of this machine in the field of refrigeration and air conditioning has been studied. The simulation at various temperatures of geothermal sources of Algeria is used. The couples (refrigerant / absorbent) used are (R600a-DMF), (R32-DMAC) and (R134a-DMETEG). The curves of (H, X, T) and activity coefficient in the part of the generator and the absorber based on vapour-liquid equilibrium are plotted, and secondly COP of the system has been calculated.
